Studies on the impact of xenobiotics: its molecular biomarker development in (shell and fin) fish model and bioremediation in aquatic system.


             It is well known that xenobiotics impair the aquatic organisms at different level. The potent and virulent xenobiotics at the higher concentrations cause, organism toxicity i.e. killing the animals, the moderate concentrations cause organ toxicity i.e. impair the physiology of related organs, whereas the trace (< nano) level concentrations (usually undetectable by even sophisticated instrument, thus we feel safe therefore allowed within the limits of National and international standards, as safe) impair cellular / molecular system. In most cases the exposed animal able defend against the xenobiotics through different mechanism (avoid by escaping from the area, mucous production, reducing its physiology etc) for their existence. In the cellular level, metabolic enzymes come for rescue. The secretion of enough specific enzymes to neutralize the effect of xenobiotics to its capacity, otherwise the failed animals subsequently die.
Further the long time exposure to trace concentration (or one time exposure to higher also moderate concentrations) can express its impact after a long time at molecular level i.e., they majority get disrupted their endocrine functioning either as agonist or antagonist. Thus body regulatory mechanism become tilted and most particularly affect the reproductive system, leads to irregular sex disorder causing imposex, ambiguous sex and even sex reversal in the susceptible organism. Continuation of such sex reversal in a particular population results with the development of unisex population. Generally sexual differentiation/dimorphism is essential in many animals to precede nuptial activity, thus the morphologically unisex population unable to breed and propagate; ultimately leads to the extinction of the species .Therefore trace level xenobiotic are more dangerous in the eradications of a species.
Bioremediation: the act of adding materials to contaminated environments such as oil spill sites, to cause an acceleration of the natural biodegradation process- is a promising means by which oil released environments. Microbial seedings as a means of enhancing oil biodegradation, has even greater uncertainties associated with it, especially in system such as coastal marsh where hydrocarbon degrading bacteria are naturally prevent, the implementation of this mechanism could prevent the marine oil pollutions.
