Opis:: Evidence of changes in weather parameters like ambient temperature, precipitation, wind flow, etc., are prominently visible across the world. These changes have been reported to effect global crop yield. This review compiles both direct and indirect effects of climate change on global crop productivity with highlights on existing local and global scenarios. As a conclusion, it may be stated that thorough understanding of agricultural techniques and analysis of global change factors is highly essential for achieving sustainable agricultural yield over the upcoming years.

Opis:: As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three concentrations of zinc were tested at different durations such as 24h, 48h, 72h and 96h respectively. Highly significant (P < 0.001) increased values were obtained for MN frequencies in the peripheral erythrocytes of exposed fishes compared to control groups of fishes. These results confirm that dose- and time-dependent micronucleation in the peripheral erythrocytes of fish after short-term exposure to zinc could provide valuable information regarding zinc containing effluent quality and also help in genetic biomonitoring with this test model. In this context safe concentration of zinc vis-a-vis genotoxicity range could be evaluated for future studies.

Opis:: During the past two decades, Arsenic (As) contamination via groundwater has become a serious issue worldwide and is now a major concern in the Indo-Bangladesh Gangetic delta. Arsenic enters human body through contaminated groundwater consumed as drinking water. Food safety in this region is also facing severe consequences as bio-accumulation of Arsenic is occurring in food crops irrigated with As-contaminated water. Chronic exposure to Arsenic can cause not only cancerous and non-cancer health effects. Reports suggest that about 20 % population in West Bengal is highly affected. Various techniques are being introduced to provide arsenic-free drinking water at an affordable cost. But a rigorous change in habit and mind set for procuring safe drinking water in those surviving in As-contaminated zones is the most essential step towards curbing the fatal consequences of As exposure. Harvesting rain water and utilization of proper purification techniques can be considered a possible alternative of safe drinking water.
