Abstract

Crude oil spills, oily sludge and petroleum industry effluents are considered to be a major problem due to their high toxicity and polluting nature. Terrestrial and aquatic life is being affected by it. Safe disposal of them is a serious problem, due to their polluting nature. Bioremediation is a natural and effective phenomenon to minimize their toxicity. Bioremediation simply uses the transforming nature of bacteria and other microorganisms, through which they use few toxic compounds of crude oil and uses or degrade them into simpler forms. There are several methods which can alter the rate of bioremediation such as temperature, pH, salinity, etc. carcinogenic nature of toxic components of crude can certainly affect living organisms in several ways. They have their impact on most of the systems and relate organs of the human body, such as reproductive system, digestive system, nervous system, circulatory system etc. harmful affects of crude oil are also noticed and studied on plants and animals
