Impact of oil spill on : birds ii. Marine Life iii. Mangroves i. IMPACT ON BIRDS DUE TO OIL SPILL ANIMATION OF OIL SPILL IN GULF OF MEXICO FLOW CHART OF OUR STUDY ANALYSIS OF PROBLEM DATA COLLECTION FAULT TREE ANALYSIS PROBABLITY CALULATION MINIMAL CUTSET TECHNIQUE RELIABILITY DIAGRAM RISK ASSESSMENT A. HAZARD IDENTIFICATION Carcinogenic Component of Oil Spill : Cr, Hg, Organo-phosphorous and benzene Non Carcinogenic Components : Zn, CH4, NaOH, Pyrothroid, Ethyl Benzene, Cr, Toulene, Napthalene, Xylene B. EXPOSURE ASSESSMENT The concentration of the contaminants of Oil spill are found in air, water and in sediments and based on the data study the concentration of PHc(Petroleum Hydrocarbons) is found to be abnormally high. C. DOSE-RESPONSE ASSESSMENT Based on the Toxicity score, Cr is found to be most toxic in air while PHc in water. Where as on account of Lifetime Excess Cancer Risk benzene is found to be most carcinogenic in both air and water. D. RISK MANAGEMENT Bioremediation: ‘a cocktail of bacteria’ basically eats hydrocarbon compounds found in crude oil and turns them into CO2 and water. Surface Dispersants:. Surface dispersants absorb the oil particles suspended in the water, thus reducing the oil slick to droplets which can be easily degraded by naturally occurring bacteria. E.
