the surface sediment samples were analyzed for grain size carbonates (caco3) and organic carbon (oc) to obtain a preliminary view of its environmental conditions near point calimere along the southeast coast of vedaranyam, india. the total concentrations of major elements namely, si, al, fe, ca, mg, na, k and p in the surface sediments of vedaranyam coast are estimated. the element/al ratios al...
BACKGROUND Exposure to ambient particulate matter (PM) has been associated with adverse cardiovascular effects in epidemiological studies. Current knowledge of independent effects of individual PM characteristics remains limited. METHODS Using a semi-experimental design we investigated which PM characteristics were consistently associated with blood biomarkers believed to be predictive of the...
Urban lakes have a particular influence on the water cycle in urban catchments. Thermal stratification and a longer residence time of the water within the lake can boost the phytoplankton production. On the other hand, trace metals are naturally found in environment in trace amounts due to erosion and physic-chemical or biological alteration processes. Trace metals are essential to growth and r...
The intertidal copepod Tigriopus japonicus has been recognized as a potential model species for toxicity testing of marine pollutants. In last five years or so sequence information and expression pattern of several genes critical in detoxification, stress, growth and reproduction have been described from T. japonicus. A number of genes, especially those representing antioxidant and detoxificati...
Minerals are one of the components of food, though they are not synthesized in the body but they are essential for optimal health. Several essential metals are required for the proper functioning of many enzymes, transcriptional factors and proteins important in various biochemical pathways. For example Zn, Mg and Mn are cofactors of hundreds of enzymes, and Zn is involved in the synthesis and ...
