Research Interest :
Fate of organohalogens (Organochlorine pesticides [DDTs, HCHs, HCB, and chlordane compounds such as {cis/trans-chlordane, cis/trans-nonachlor, oxychlordane, heptachlor, heptachlor epoxide} cyclodienes {aldrin, dieldrin, endrin}, toxaphene, mirex]), Polychlorinated biphenyls (PCBs) and its hydroxylated metabolites (OH-PCBs), Chlorinated and Brominated Dioxins (PCDDs/PBDDs), Chlorinated and Brominated Furans (PCDFs/PBDFs), Brominated Flame Retardants (BFRs) such as Polybrominated diphenyl ethers (PBDEs) and its hydroxylated metabolites (OH-PBDEs), Polybrominated biphenyls (PBBs), tetrabromo bisphenyl A (TBBPA), hexabromocyclodecane (HBCD), polychlorinated naphthalanes (PCNs), Polychlorinated alkanes (PCAs), Fluorinated Organic Compounds (FOCs such as perfluoro carboxylic acids “PFCs” and perfluoro sulfonic acids “PFSs” and fluoro telomer alcohols[FTOHs]/aldehydes and Butyltin compounds “BTs”), antibacterial chemicals such as triclosan (TCS), triclocarbon (TCC), environmental hormones such as bisphenol-A (BPA), nonylphenol (NP), octylphenol (OP) in the environment.
Food-web transfer of organic contaminants such as bio-concentration factor (BCF), bio accumulation factor (BAF) and bio-magnification factor (BMF) and biological metabolism.Sources, formation, human and wildlife exposure and intrinsic toxic effects.
Specialized interests in avifauna, marine mammals, freshwater animals, terrestrial animals and environmental samples. Especially on levels, distribution pattern, homologue distribution, congener pattern, toxicology, toxic threshold.
Grassland beneficial microbial dynamics such as litter decomposing fungi, N2-fixing -bacteria, -azospirillum, -azotobactor, P-solubilizing -bacteria, -actinomyces, -fungi, arbuscular mycorrhizal (AM) fungi colonies in root & AM spore species in rhizosphere soil. Grassland soil chemistry such as physical, chemical and biological properties. Biomass production, productivity, turnover rate and time in dominant grass, legume and other dominant plant species in natural grasslands. Litter decomposition by fungi percentage frequency and occurrence of decomposing fungi in decomposing plant litter and in rhizosphere soil. Grassland ecology, microbiology etc.,
