In this study, the uptake and transport of seed-coating pesticides (insecticides), including cyantraniliprole (CYN) and thiamethoxam (THX), were investigated. The translocation of these pesticides from the soil to the plant and their accumulation in different plant parts were also calculated. After sowing the seeds with seed coating pesticides, soil and plant samples were taken across the study area. These samples were extracted and analyzed in liquid chromatography with tandem mass spectrometry (LC-MS/ MS). CYN and THX were used in maize plants for the first time to observe soil degradation kinetics, and CYN showed a higher half-life than THX in soil. Both pesticides have been taken up by the corn maize plant and transferred and accumulated to the upper parts of the plant. Although the THX concentration was between 2.240 and 0.003 mg/kg in the root, between 3.360 and 0.085 mg/kg in the stem, it was between 0.277 and 3.980 mg/kg in the leaf, whereas CYN was detected at higher concentrations. The concentration of CYN was 1.472 mg/ kg and 0.079 mg/kg in the roots and stems of the maize plant, respectively. However, the bioconcentration factor (BCF) indicates the soil-to-plant accumulation of CYN from 28 to 34.6 and that of 12.5 to 4567.1 for THX on different sampling days. The translocation factor (TF stem) represents the ratio of pesticides absorbed from the stem and transported to the roots. For CYN, TFstem ranges from 3.6 to 20.5, while for THX, it varies between 1.5 and 26.8, indicating a higher translocation rate for THX. The ratio of leaf to root concentration are 3.6 to 20.5 for CYN and 1.8 to 87.7 for THX, demonstrating effective translocation for both pesticides. The TF values for both pesticides are above 1, signifying successful root-to-stem-to-leaf movement. Notably, THX exhibits a notably higher transport rate compared to CYN.

Without strict monitoring and enforcement of the measures, no action plan can work. Punishment of defaulters can serve as deterrence while also instilling fear in other non-compliant enterprises. In comparison to environmental legislation, the NGT Act allows for substantially harsher fines and penalties. River rejuvenation plans must be carefully monitored to ensure that they do not suffer the same fate. Making action plans will not improve river water quality unless they are implemented with sincerity and consistency, as well as continuous monitoring and severe enforcement.

The present research work is based on a scientific hypothesis, i.e., "The removal of average pesticide residue is inversely proportional to the thickness of cuticle." The effects of boron-containing products and plant-based surfactants were tested for the removal of five pesticides (lambda-cyhalothrin, chlorpyrifos, diflubenzuron, metaflumizone, acetamiprid) on tomatoes and apples. Boron-containing products were able to remove the pesticide residues on average between 58.0 and 72.6% in tomatoes and 33.2-58.8% in an apple. While plant-based surfactants removed residues on average between 58.5 and 66.6% in tomatoes and 41.0-53.2% in an apple. The highest removal rate was 72% with etidot at 1%. The solution of 1% C8-C10 provided 66.6% average removal for tomatoes. Less removal was achieved in apples. For an apple, Log K ow and molecular mass (independent variables) were significant with p < 0.01, and the coefficient of determination (R 2) was > 0.87. However, the multiple linear regression analysis for ground colemanite was significant with R 2 of 0.96. In tomatoes, neither Log K ow nor molecular mass as significant. The correlation was found between the physical and chemical properties of pesticides, but it is estimated that the thickness of the cuticle is effective in removing pesticides.

Plastic and polythene are commonly used for food and water packaging. The polymer which can be shaped of anything with high pressure and temperature is known as “plastic” (Sharma, 2018). It is nondegradable solid waste (polymer of ethylene monomers). It resists microbial degradation and remains unchanged in the environment for years and therefore it is a major environmental concern. The decomposition of plastic material is serious trouble for the solid waste management sector. The first fully synthetic plastic was invented by Leo Hendrik Baekaland in the year 1907 (Crespy et al., 2008). It is used as a matrix for several composites. The extensive use of plastic in industrial, agricultural, and domestic sectors is resulting in severe environmental contamination. The general formula for polyethylene is [CH2 2 CH2]n (Yang et al., 2014). There are many types of polyethylene based on density, viz. low-density polyethylene (LDPE), very low-density polyethylene, medium density polyethylene, and highdensity polyethylene (HDPE) (Fried, 2003). However, LDPE is commonly used for the production of carrier bags; packaging and electric casing; laboratory materials; etc. (Table 28.1) (Tachwali et al., 2007). The plastic is lightweight, versatile, inexpensive, and durable (Comani ˘ ța et al., 2016 ˘ ). It can resist acid materials and therefore it is extensively employed for chemical storage in the laboratory. Wide uses of plastic in every possible sector are making it a more sensitive issue to manage solid waste. It is the peak time to solve this environmental concern. There are several chemical and physical methods of plastic degradation. Eventually, these existing physical and chemical methods are producing more toxic substances as intermediates or by-products (Jaiswal et al., 2019). Therefore, it is wise to adopt an easy and safe alternative method to degrade this plastic waste. Interestingly, microbes are the key to solve this environmental concern by bioremediation techniques.

The driving force of the hydrological cycle is the sun. We people are continuously trying to win the world and challenge nature through our everyday activities but actually, these are dangerous stepping stones towards the end of existence of life on this beautiful planet. We should not forget that the groundwater has limits. Some environmentalists have already quoted, "The third world war will be due to water crisis." and coined the term 'Water war'. This war will be very disastrous than the previous two wars. This may be stopped only and only by the daily activities of each human being. Because man is the main constructor and modular of nature and only human being has an efficient brain to think about than the other animals. Hence, it is the prior duty of humans that we all should save every drop of water as water is a very precious resource on the planet. The rainwater is the ultimate source to recharge the groundwater. Now a day groundwater level is gradually and continuously depleting because of over-extraction and injudicious use. That may be the alerting bell about the upcoming world-war and therefore being eco-friendly we should take some stand to save the water. Here are some options to overcome this environmental problem such as Judicious use of water Use recycled water wherever possible Use treated water for domestic purpose Use treated water for washing and boiling purpose at the industrial level (both small scale and large scale) Besides these one can use rainwater which is being wasted in huge quantity unknowingly every year. The way of conserving this water is through Rain Water Harvesting (RWH). This is a new trend (already adopted in many developed countries) coming in eco-friendly houses, buildings, and institutions for conservation of water. Methods of rainwater harvesting: 1. Storage of rainwater in underground or aboveground artificial tanks. The artificial tanks can be constructed above ground as depicted in Fig. No. 1 or under ground as in Fig No. 2 however, catchment area is roof top of the buildings. This kind of harvesting can store millions of litre water per rainy season. This water can be used for gardening and car wash, flushing, firefighting, etc. Each fire brigade station must have this plant of their own in heavy rains areas. Water is acquired from the direct roof of the building to the artificial tanks.

However, due to indiscriminate use of agrochemicals, growth regulators, and fertilizers, reduces the exportable quality of fruit. Therefore, it is well felt need to adopt sustainable pest management.

Evidence shows non-targeted species gets impacted more due to chemical pesticides than targeted species. Only about 1% of pesticide reaches the target pest and the rest of it induces contamination of the environment (Amoabeng 2014, Tyler and Miller, 2004). Much of the pesticide residuals also reaches the aquatic ecosystem through runoff (Tashkent 1998). Spraying of chemical pesticides also unintentionally contaminates neighbouring habitats and the atmosphere through drift and evaporation (PMEP 1993, Tashkent 1998, Gil and Sinfort 2005).

However, increasing use of chemical pesticides and fertilizers for longer duration has shown deterioration in the taste and hence marketability of the fruit. There are several incidence of rejecting batches of mango fruits, in the international market because of presence of heavy metal traces above the internationally agreed norms. Therefore, it is well felt need that mango growers in Ratnagiri district should reduce the use of Chemical pesticides responsible for bioaccumulation of heavy metal traces. It is necessary to replace such chemical pesticides by biopesticides like Karanj, Neem, Cow urine etc. Can it be possible? If such replacement is effective, what would be the cost? Can we prepare a strategy to promote use of biopesticides and avoid heavy metals concentrations? With such questions in the mind the present study would be carried out. Such study may start with the understanding of quantity of pesticides used in the district and to carry out impact analysis of the same. The study may propose appropriate strategy to reduce the use of chemical pesticide and to encourage use of biopesticides. For this, the study entitled, "Impact of Selected chemical Pesticides on the Mango plantations ecology a case study of Ratnagiri District, Maharashtra", has been undertaken. 1.4 Hypothesis Use of chemical pesticides on mango cultivation would cause significant degradation of ecosystem. It may be checked by adopting organic methods of cultivation for which acceptance level among the mango growers in Ratnagiri district is quite promising. 1.5 Objectives To assess impacts of selected chemical pesticide (Imidaclorid, Cypermethrin, Quinalphos and Hexaconezole) and heavy metals on mango plantation. To study effectiveness of biopesticides to control frequently occurring pest on mango plantation in the study area. To carry out comparative cost benefit analysis of chemical and biopesticides used in mango orchards. To design appropriate strategy for replacing chemical pesticides with bio control methods.

India features a diverse range of wetlands, including high-altitude alpine lakes, littoral swamps in the form of mangroves and corals, and inland wetlands of various sorts. The Upper Ganga Ramsar Site is Uttar Pradesh's only Ramsar Site geographical distribution and may fluctuate as a result of climate change. Wetland reactions to climate change are frequently left out of global climate change models. The climate change adaptations must be incorporated into the economic development, planning, and implementation process.

This is the cursory study of Western Ghats Ratnagiri by adapting survey technique for 20 selected sample villages which touches the Western Ghats. The data acquired from survey is cross checked by reference books and available online material. About 88 species of medicinal plants from 53 different families are observed out of which about 5 species are endemic to Western Ghats. The results obtained from present study does not indicate the actual biodiversity of the study area but it is very useful to understand the medicinal value of the western ghats of Ratnagiri and here mitigation plan is also suggested for the conservation of the biodiversity of study area.
Key words: Biodiversity, Medicinal value, Conservation.

Alphonso variety of mango commercially grown in Ratnagiri is very famous in national and international market for its characteristics taste. There are so many evidences which show the ban on mango in the international market. Toxic chemicals used in the agriculture such as pesticides, herbicide etc are bioaccumulated. Substances that bioaccumulate include some carcinogens and heavy metals. The present study tries to find out heavy metal trace Viz. Cu, Zn, Cd, Cr and Pb in the regional mango products (5 samples) that are exported to the national as well as international market. In the present study observed heavy metals total input are in following order Zn > Cr > Cu > Cd > Pb.

Area covered by Mango canopy is 67,749 hectors in Ratnagiri District According to Census 2012-13. The expenditure going towards the mango orchard management is increasing because expense on the Chemical Pesticide used by farmers to spray is more. Expected results of these chemical pesticides are not found every time. Chemical pesticide leads to very harmful effects on the ecosystem and also on the mango plant ultimately on fruit. The present paper tries to find out effect of chemical pesticide on mango orchard in Ratnagiri district.

About 67,749 hectors of land is under Mango canopy according to census 2012-13. Unsustainable agricultural practices lead to degradation of quality of mango fruits. This year also mango grower used pesticide in their orchard but then also European countries rejected Mangoes from India Because of low quality i.e. problem of fruit flies and mango stone weevils. This may because of pest started to develop resistance towards the chemical pesticide. Therefore it is better to use organic methods for controlling the pest. It become easier for pest to develop resistance towards chemical pesticide in contrary to that it is difficult for pest to develop resistance towards organic pesticides. The present paper tries to find out consumption of pesticide used at each Tahsil. Also paper attempts to suggest possible methods to use organic pesticides.

Most individual phytoplankton is too small to be seen with the naked eye, their small size is principle adaptation for keeping them into the photic zone. Results observed in two different seasons viz premonsoon and monsoon. Data collected at high tide and low tide for the above mention seasons. Analysis is done for percent diversity, composition of abundant genera in premonsoon and monsoon seasons, comparison of surface phytoplankton abundance no/l at high tide and low tide in premonsoon and monsoon. Comparison of surface phytoplankton abundance no/l in premonsoon and monsoon season.
Navicula spp. was most abundant phytoplankton in both seasons. The phytoplankton are richly observed in HT than LT.
Diatoms absorbs carbon dioxide from the atmosphere therefore contributing to minimizing green house effect. Phytoplankton in one of the good bioindicators. it helps us to show effect of mining on the phytoplankton abundance thereby on the whole marine food chain.

The polymer which can be shaped of anything with high pressure and temperature is known as “plastic” (Sharma,
2018). It is nondegradable solid waste (polymer of ethylene monomers). It resists microbial degradation and remains
unchanged in the environment for years and therefore it is a major environmental concern. The decomposition of plastic
material is serious trouble for the solid waste management sector. The first fully synthetic plastic was invented by Leo
Hendrik Baekaland in the year 1907 (Crespy et al., 2008). It is used as a matrix for several composites. The extensive
use of plastic in industrial, agricultural, and domestic sectors is resulting in severe environmental contamination. The
general formula for polyethylene is [CH2 2 CH2]n (Yang et al., 2014). There are many types of polyethylene based on
density, viz. low-density polyethylene (LDPE), very low-density polyethylene, medium density polyethylene, and highdensity polyethylene (HDPE) (Fried, 2003). However, LDPE is commonly used for the production of carrier bags;
packaging and electric casing; laboratory materials; etc. (Table 28.1) (Tachwali et al., 2007). The plastic is lightweight,
versatile, inexpensive, and durable (Comani ˘ ța et al., 2016 ˘ ). It can resist acid materials and therefore it is extensively
employed for chemical storage in the laboratory. Wide uses of plastic in every possible sector are making it a more sensitive issue to manage solid waste. It is the peak time to solve this environmental concern. There are several chemical
and physical methods of plastic degradation. Eventually, these existing physical and chemical methods are producing
more toxic substances as intermediates or by-products (Jaiswal et al., 2019). Therefore, it is wise to adopt an easy and
safe alternative method to degrade this plastic waste. Interestingly, microbes are the key to solve this environmental
concern by bioremediation techniques.

India features a diverse range of wetlands, including high-altitude alpine lakes, littoral swamps in the form of mangroves and corals, and inland wetlands of various sorts. The Upper Ganga Ramsar Site is Uttar Pradesh's only Ramsar Site geographical distribution and may fluctuate as a result of climate change. Wetland reactions to climate change are frequently left out of global climate change models. The climate change adaptations must be incorporated into the economic development, planning, and implementation process.

fight against the coronavirus disease 2019 (COVID-19)
pandemic. All the affected 223 countries are endeavouring and
adopting every measure to put a stop to community
transmission. The mortality rate of the critically sick patients
with COVID-19 is very high. Hence, the present review is an
effort to create an exact awareness among researchers and
readers. Primarily, this review possesses the data regarding the
origin of the virus, classification and structure of the Severe
Acute Respiratory Syndrome coronavirus-2, symptoms of
corona disease, possible treatments undertaken, preventive
measures adopted, etc. However, the major focus is on the
impact of lockdown on air and water quality as well as the
ozone (O3) layer. In this review, it is observed that Air Quality
Index is drastically decreased for metropolitan cities like Delhi,
Mumbai, Chennai, and Kolkata. The concentrations of
particulate matter (PM) 10, PM 2.5, SOx, NOx, CO are
decreased. However, ozone concentration in the atmosphere is
increased substantially. Whereas, rivers seem to be clean due to
the improvement in their self-cleansing property. The remedies
are given to maintain the environment clean after lockdown.

contamination. Evidence shows non-targeted species
gets impacted more due to chemical pesticides than
targeted species. Only about 1% of pesticide reaches the
target pest and the rest of it induces contamination of the
environment (Amoabeng 2014, Tyler and Miller, 2004).
Much of the pesticide residuals also reaches the aquatic
ecosystem through runoff (Tashkent 1998). Spraying of
chemical pesticides also unintentionally contaminates
neighbouring habitats and the atmosphere through drift
and evaporation (PMEP 1993, Tashkent 1998, Gil and
Sinfort 2005).

Though, several researchers proved that many plant extracts are effective against varieties of insects. But there is lack of information regarding its economic analysis as compared to competitive chemical insecticide available in the market. In present study economic analysis of formulated bio insecticide (by using Strychnos nux vomica and Neem oil) and synthetic insecticide (Imidacloprid) against mango leaf hopper is carried out. The results obtained were compared with control where no spraying of either synthetic or formulated insecticide. The cost benefit analysis was carried out to check feasibility of formulated botanical insecticide.
The cost benefit ratio (CBR) obtained for formulated insecticide was 1:1.83 However, CBR for selected synthetic insecticide was 1:1.25. Therefore formulated insecticide proved to be safer and feasible as it is produced from widely available plant in Konkan region viz. Strychnosnux-vomica and Azadirecta indica. The newly formulated insecticide can be produced on large scale and provided to the other farmers. Consequently, it can be a source of income for local people in the Konkan region.

Alphonso variety of mango is world famous because of its taste and longer shelf life.
However, increasing use of chemical pesticides and fertilizers for longer duration has
shown deterioration in the taste and hence marketability of the fruit. There are several
incidence of rejecting batches of mango fruits, in the international market because of
presence of heavy metal traces above the internationally agreed norms. Therefore, it is
well felt need that mango growers in Ratnagiri district should reduce the use of
Chemical pesticides responsible for bioaccumulation of heavy metal traces. It is
necessary to replace such chemical pesticides by biopesticides like Karanj, Neem, Cow
urine etc.
Can it be possible? If such replacement is effective, what would be the cost? Can we
prepare a strategy to promote use of biopesticides and avoid heavy metals
concentrations?
With such questions in the mind the present study would be carried out. Such study may
start with the understanding of quantity of pesticides used in the district and to carry out
impact analysis of the same. The study may propose appropriate strategy to reduce the
use of chemical pesticide and to encourage use of biopesticides. For this, the study
entitled, "Impact of Selected chemical Pesticides on the Mango plantations ecology a
case study of Ratnagiri District, Maharashtra", has been undertaken.
1.4 Hypothesis
Use of chemical pesticides on mango cultivation would cause significant degradation of
ecosystem. It may be checked by adopting organic methods of cultivation for which
acceptance level among the mango growers in Ratnagiri district is quite promising.
1.5 Objectives
To assess impacts of selected chemical pesticide (Imidaclorid, Cypermethrin,
Quinalphos and Hexaconezole) and heavy metals on mango plantation.
To study effectiveness of biopesticides to control frequently occurring pest on
mango plantation in the study area.
To carry out comparative cost benefit analysis of chemical and biopesticides used in
mango orchards.
To design appropriate strategy for replacing chemical pesticides with bio control
methods.

The driving force of the hydrological cycle is the sun. We people are continuously trying to win the world and challenge nature through our everyday activities but actually, these are dangerous stepping stones towards the end of existence of life on this beautiful planet. We should not forget that the groundwater has limits. Some environmentalists have already quoted, "The third world war will be due to water crisis." and coined the term 'Water war'. This war will be very disastrous than the previous two wars. This may be stopped only and only by the daily activities of each human being. Because man is the main constructor and modular of nature and only human being has an efficient brain to think about than the other animals. Hence, it is the prior duty of humans that we all should save every drop of water as water is a very precious resource on the planet. The rainwater is the ultimate source to recharge the groundwater. Now a day groundwater level is gradually and continuously depleting because of over-extraction and injudicious use. That may be the alerting bell about the upcoming world-war and therefore being eco-friendly we should take some stand to save the water. Here are some options to overcome this environmental problem such as Judicious use of water Use recycled water wherever possible Use treated water for domestic purpose Use treated water for washing and boiling purpose at the industrial level (both small scale and large scale) Besides these one can use rainwater which is being wasted in huge quantity unknowingly every year. The way of conserving this water is through Rain Water Harvesting (RWH). This is a new trend (already adopted in many developed countries) coming in eco-friendly houses, buildings, and institutions for conservation of water. Methods of rainwater harvesting: 1. Storage of rainwater in underground or aboveground artificial tanks. The artificial tanks can be constructed above ground as depicted in Fig. No. 1 or under ground as in Fig No. 2 however, catchment area is roof top of the buildings. This kind of harvesting can store millions of litre water per rainy season. This water can be used for gardening and car wash, flushing, firefighting, etc. Each fire brigade station must have this plant of their own in heavy rains areas. Water is acquired from the direct roof of the building to the artificial tanks.
