Water pollution caused by industrial effluent discharges has become a worrisome phenomenon due to its impact on environmental health and safety. The effluents of some industries were collected and samples were analyzed to assess major ionic constituents, trace metal pollution and suitability for irrigation usage. An investigation has been made to ascertain the metals concentration in the effluents samples collected from different industries located in Choto kashor, Bhaluka. This study involves determination of physicochemical parameters and trace metals of industrial effluents at different study points. The pH of the effluent water ranged from 7.5 to 9.8 with a mean value of 8.59 indicating alkalinity of water. EC of all collected effluent samples were within the range of 94.87 to 365.58 +S cm-1 with an average of 263.082 +S cm-1 indicating effluents of low salinity. The DO was within the range of 0.30 to 1.3 mg L-1 indicating that aquatic life is in under stress. Total dissolved solids (TDS) ranged from 53.68 to 267.05 mg/L. Considering TDS, all the samples were rated as fresh water (<1000 mg L-1). On the other hand, the cationic chemistry indicated that most of the samples showed dominance sequence as Na > K > Ca. Concentrations of Cu (0.0405 mg/L) and Pb (0.0003 mg/L) were found lower the allowable levels of industrial waste water. Among the studied trace metals (Cd, Pb, Ni, Cu, and Zn), the dominant metal was Zn and although the concentration varied from 0.2 to 1 mg/L, which are suitable for irrigation but unsafe for the purpose of aquaculture. Besides this, all of the effluent samples possess no Cd and Ni which comprises less the minimum acceptance level indicating there is no possibility of Cd and Ni contamination to harm aquatic organisms along with irrigation. However, the waste water of the study area can be used for irrigation hence it is acceptable considering quality for aquaculture except some sampling sites. High values of some properties of distinct samples reveals the suitability for irrigation but restricted the suitability of water in this area for aquaculture and domestic use. Moreover it demands suitable water management as well as proper treatment and possesses the necessity to pre-treat the wastes prior to release to the environment or fully treatment when the wastes will be discharged directly to surface or ground waters.

A questionnaire survey was conducted at selected community members living at or near brick field areas with aim to assess impacts of brick fields on air, water, soil, vegetation as well as socioeconomic conditions. Findings of this study were based on randomly selected respondents' perception on change of any resource or condition. Crop loss, decreased soil fertility and subsequent reductions in crop production were reported. Trees around brickfields were dusted badly and water quality of nearby water bodies deteriorated because of emerged dust and ash from brick fields. Noticeable negative impacts on aquaculture were found. Except few, majority of the respondents were suffering from various diseases like eye irritation, skin diseases and respiratory problems. Despite creating work opportunities for local people, brick fields of the study area adversely affected environment and social economy.

Plants are very crucial to the human being not only for the uses in health-care, but plants are also used for various other purposes such as sources of new pharmaceuticals. Ethnomedicinal plants have been used since a long time for human health care and most widely used for medication system in developing and least developing countries. People of different communities in Bangladesh use medicinal plants and rely on ethnomedicine because of cost-effectiveness, acceptability, biomedical benefits and less or no side-effects. It is very likely that these phytochemicals will find their way into the arsenal of antimicrobial drugs prescribed by physicians. People in Bangladesh are becoming concerned with the over-prescription and misuse of allopathic antibiotics and antimicrobial resistance is increasing simultaneously in this regard. Ethnomedicine can be used as alternatives to traditional antibiotics, hence, can overcome the problems of antibiotics.

Concentration of different parameters i.e. pH, temperature, color, odor, electrical conductivity (EC), dissolved oxygen (DO), total dissolved solids (TDS) and concentration of ionic constituents viz. Na+, K+, Ca2+ and PO42- of effluents were investigated in Bhaluka industrial area of Mymensingh, Bangladesh during August to November, 2013. Study revealed that there were distinct variations in values of different parameters. Among the samples, pH values ranged from 7.5 to 9.8 indicating alkalinity of water. Temperature (26.8-30.2oC) was found within permissible expelling limits. Observed color and odor of the effluents indicated poor quality to use for irrigation and aquaculture purposes. EC value (94.87-365.58 µScm-1) indicated low salinity level of the effluents. DO was within the range of 0.30 to 1.3 mg/L indicating aquatic life was under stress. Considering TDS (53.68 to 267.05 mg/L), all the samples were rated as fresh water (<1000 mg/L). Ratios of mean concentrations to background values were ranked in this sequence: Na+> K+> PO43-> Ca2+. Overall study revealed that due to imbalance in values of different water quality parameters all of the samples were unsuitable for irrigation and aquaculture.

Atomic absorption spectrometer (AAS) was used to evaluate the concentration of Zinc (Zn), Copper (Cu), Nickel (Ni), Cadmium (Cd), Chromium (Cr) and Lead (Pb) in the samples. The study revealed that heavy metals were present in variable amounts, where the concentrations of Cu (0.0405 ppm) and Pb (0.0003 ppm) were found lower than recommended level for industrial waste water. Among the present trace metals, the highest concentration (0.2-1.0 ppm) was found in Zn. Although the concentration is suitable for irrigation, it is unsafe for aquaculture. Besides, all of the wastewater samples possessed no Cr, Cd and Ni, which comprised less of the minimum acceptance level, indicating no possibility of contamination. However, comparing findings of this study with the safe limits for industrial wastewater, it can be concluded that the waste water of the study area except some sampling sites can be used for irrigation and aquaculture.

A total of 42 water samples were collected from seven different locations adjacent to the Balu river area of Dhaka and Narayanganj district during September and October 2013. To study the water quality status, different physical and chemical properties viz. pH, EC, concentration of PO4, NO3-N, NH4-N, heavy metals viz. (Cu, Zn, Pb, Fe and Cd) were investigated and compared with the standards set by DOE (Department of Environment), Bangladesh. The study revealed that Balu river water properties changed with different months. Water colour was found as highly objectionable. The mean pH value (6.54 during September and 6.17 during October) indicated acidic nature of the water. Mean EC value (2.12 mS cm-1 during September and 0.39 mS cm-1 during October) and mean concentrations of PO4 (10.64 mg L-1 during September and 4.75 mg L-1 during October) exceeded the recommended limit for drinking and irrigation water. Mean concentration of NO3-N (1.74 mg L-1 during September and 1.21 mg L-1 during October), NH4-N (5.20 mg L-1 during September and 9.12 mg L-1 during October), The study indicates that the water of this river is not an immediate threat to ecosystem during September and October, but as some parameters exceeded the permissible limit, in future it may cause a potential threat to the ecosystem.

The CPP project made a sluice gate on the Louhajang River at Jugini to protect the Tangail town from flood. There is a great impact of the sluice gate on the CPP area and also on agriculture and fisheries of the two parts of the sluice gate area. A study was conducted to assess the effects of sluice gate on fisheries and agricultural production both in upstream and downstream of the Jugini sluice gate in Tangail sadar during the period of July to December 2011. The study was performed mainly through survey methods with the assist of questionnaires and secondary information’s. The results of the study showed that the agricultural production increased in the downstream where the fisheries production decreased gradually. The present data was also compared with the secondary data collected from CPP since its construction on Louhajong River at Jugini. In dry season, irrigation problems occurred due to unavailable source of water. To check the upstream problems, an embankment on the Louhajang River on the upstream part is necessary to build. The sluice gate was established aiming for controlling flood and benefits for downstream area people. Hence, there is no changed in upstream part, moreover upstream area is flooded every year and damage crops, decreases natural fish production. Therefore, it is necessary to practice alternative way for fish culturing with proper training where crop land fish cultivation might be an easy accessible method.

It also explored the possibilities of overcoming the negative impacts of floods on sources of safe drinking water and sanitation. The study result shows that, about 54% of the overall latrines were included ring slab with water seal, pit latrine, bush or hanging toilet of the flood affected people during the flood. Around 19% of the respondents use to do toilet in the open area during flood. Different NGOs e.g. Jamuna Char Development Project (JCDP), Bangladesh Rural Advancement Committee (BRAC), CARE and Red Crescent Society of Bangladesh works for rehabilitation of the flood affected people and give early warning on the flood. Depending on location and sanitation conditions, drinking water sources may be contaminated by flood water during flood and many waterborne diseases can spread out like Cholera, Dysentery, Diarrhoea, diseases of the skin, Typhoid etc. meantime. The conducted survey also reports that, drinking water and sanitation condition is not dependable (on the commentary of 64.8% of the responders). Therefore, the flood affected people of Bhuapur are usually underprivileged from appropriate sanitation facility on flood. They somehow conform themselves while a chain of problems strikes hardly during flood.

Disposition of tanning effluents e.g. Chromium (Cr) into the environment creates inauspicious outcomes by modifying the normal physiochemical properties of soil and water. It is determined that Chromium is the principal threat whenever tanning industry derives in to practice. Cr is extremely venomous and carcinogenic to humankind, animals, vegetations and as well overall environment. The paper was executed solely on secondary information by conferring literature informants including scientific journals, conference articles document and internet site that focused on the effects of tannery waste water and assessment of alternative treatment options used to reduce, removal, retrieve or reprocess Cr from the waste water. Effective management of tannery effluent is the need of the hour. Although a lot of treatment alternatives were assessed to preclude its effect on the environment, neither of them forced out Cr completely. In some cases researchers however successful enough practicing biotechnological methods to reduce the strength and fatal state of Chromium (e.g., Cr(Vl)). Hence, treatment alternatives are either; complex, energy consuming, expensive or applicable to a indisputable portions of the world due to engineering science or proficient work force requirement. Consequently, to tackle these important challenge demanding environmental ordinance with jurisprudence implementation has to be practiced to apply improve treatment scheme which is widely applicatory. Defilers must acknowledge the environmental cost of their manufacture and treated according to polluter pay or precaution precepts. Furthermore, the general public has to be aware of it and all concerned organizations and authorities have to work hard to accomplish zero discharge level or leastwise to gain the standard limit of Chromium discharge.
