Oil pollution toxicity to marine fish has been observed from oil spills such as the Exxon Valdez disaster, and from nonpoint sources, such as surface runoff, which is the largest source of oil pollution in marine waters. Crude oil entering waterways from spills or runoff contain polycyclic aromatic hydrocarbons (PAHs), the most toxic components ...
Animals can also be internally diagnosed via necropsy by identifying petroleum hydrocarbons in their fat, liver, or kidney tissues [2] For damage assessments, the death of the animal must have occurred after the oil spill. [1] The severity of damage directly correlates with the amount of oil spilled and the animal's exposure to oil. [4]

Fouling is when oil harms wildlife via coating itself on an animal or plant physically. [101] Oil Impacts on Coral Reef Communities. Oil pollution is hazardous to living marine habitats due to its toxic constituents. Oil spills occur due to natural seepage and during activities such as transportation and handling. These spills harm the marine ...
Oil is "acutely lethal" to fish - that is, it kills fish quickly, at a concentration of 4000 parts per million [25] (0.4%). The toxicity of petroleum related products threaten human health. Many compounds found in oil are highly toxic and can cause cancer (carcinogenic) as well as other diseases. [23]
United States domestic oil production hit an all-time high last week, contrasting with efforts to slice heat-trapping carbon emissions by the Biden administration and world leaders. The U.S ...
