Oil exploration and development with the threat of pollution to living marine resources has increasingly become a public issue.The shift in balance of an ecosystem from a severely altered one, immediately following a major oil spill to a stable ecosystem can require many years. Certain organisms can be killed by water-soluble fractions (WSFs) of oil and exhibit sublethal response at much lower concentrations (1 to 10 ppb). The carcinogenic properties and anthropogenic origins of polyaromatic hydrocarbons in the crude oil have led to interest in understanding their distribution and fate in the...

Indian coasts have witnessed a number of tanker disasters in recent years and regular spillage near the refineries and Mahul creeks. Refinery effluents are the major the source of oil pollution. An increasing trend of petroleum hydrocarbon in various oceans and seas has attracted attention of researchers to extensively investigate the effects of crude oil and its constituents on marine organisms. The study deals with toxicological studies gauging short term and long term sub lethal chronic toxicity of dilutions of 10 percent Water soluble fractions (WSFs) stock of Persian Gulf and Bombay High...

The present study, attempts to find out, how the degree college teachers perceive UGC's Fifth Pay commission regulations (1998) with respect to NET/SET, Contractual/ clock hour basis (CHB) appointments, In service training programmes, Work duration, Promotion conditions, Retirement age, Research and Benefits. Human resource development, at all levels, needs to be given priority and made a part of the nation's overall development strategy. For similar reasons the researcher feels that teachers view in terms of perception study can help in reviewing, monitoring and evaluation of the regulations...
