Hence, effective mosquito control is required to enhance the health and quality of human life through the reduction of mosquito population. Therefore there is a growing need to use clean non-toxic, eco-friendly biopesticides. In this review we summarize, the current knowledge of the mosquito larvicidal activity by using different plant part extracts of Solanaceae family. Various aspects such as, instar specificity, solvents used during extraction, nature of active ingredient and promising advances made in biological control of mosquito larvae from Solanaceae plant derived secondary metabolites are also discussed . The results of the review reveal that the use of Solanaceous plant extracts have the potential to be utilized as a good, easily available, biodegradable, non-toxic and in having eco-friendly approach for the control of mosquito populat...

Fin fish and shellfish were collected from eight different sampling points within 30 km radius from the Kudankulam Nuclear Power Project site. The samples were processed and counted using HPGe γ-ray spectrometry. In fin fish, 40K activity ranged from 34.16 to 360.7 Bq kg−1 fresh, 228Ra ranged from Below Detectable Limit (BDL) ≤ 0.12 to 1.9 Bq kg−1 fresh and 226Ra ranged from BDL ≤ 0.06 to 0.18 Bq kg−1 fresh. In shellfish, 40K, 228Ra and 226Ra activities ranged from 15.6 to 96.6 Bq kg−1 fresh; from 0.61 to 6.61 Bq kg−1 fresh and from BDL ≤ 0.06 to 1.15 Bq kg−1 fresh, respectively. The total daily intake resulting from consumption of fin fish and shellfish was 63.15 Bq kg−1 d−1 for 40K, 0.54 Bq kg−1 d−1 for 228Ra and 0.096 Bq kg−1 d−1 for 226Ra. The annual dosage resulting from ingestion of n...

Various studies have been carried out around this project site; however, there is no literature pertaining to the minerals in cow milk samples in this region. Further, various minerals in cow milk are analogs of natural and anthropogenic radionuclides and a study on stable elements would help to assess the behavior of their radioactive counterparts. Materials and Methods: Milk samples ( n = 25) from the study area were analyzed for macro-minerals (potassium [K], magnesium [Mg] and calcium [Ca]) and micro-minerals (zinc [Zn], copper [Cu] and manganese [Mn]) using a Z5000 series Hitachi atomic absorption spectrophotometer. The performance of the method was evaluated by using an International Atomic Energy Agency (IAEA) reference material, i.e., the fish tissue homogenate (IAEA-407). Results: The concentration values of major and trace minerals in the milk samples were in the order Ca > K > Mg and Zn > Cu > Mn, respectively. Conclusion: The high-water Ca levels and the prevailing tropical semi-arid climatic conditions seem to be the reasons for the high-Ca levels observed in the investigated milk samples. A CaCO3 bed is present in this area and lime is being excavated by cement industries and it is also evident from the literature that elevated Ca levels would have an immense impact on the levels of natural and fall out radionuclides in cow milk.

The activity concentrations were found more in the 'pulses' group and were the lowest in 'other vegetable' category. The annual effective dose was computed based on the activity concentration of radionuclides and it was found to be higher due to the consumption of cereals and pulses. Other vegetables, cereals, pulses and nuts recorded high transfer factors for the radionuclide (228)Ra. Fruits, leafy vegetables, tubers and roots, and palm embryo registered high transfer factors for (226)Ra. Group-wise activity concentration, radiation dose to the public and soil-plant-to-transfer factor are discussed in detail.
