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]
Ship and boat propellers and engines, industrial fishing, coastal construction, oil drilling, seismic surveys, warfare, sea-bed mining and sonar-based navigation have all introduced noise pollution to ocean environments. Shipping alone has contributed an estimated 32-fold increase of low-frequency noise along major shipping routes in the past ...
A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...
The shipping industry is a source of chemical pollution, including oil spills and toxic antifouling paints, which harm marine life through direct toxicity and the accumulation of pollutants in the food chain. Shipping vessel-related greenhouse gas emissions primarily come from internal combustion engines.
U.S. officials on Thursday announced a $241 million settlement with Marathon Oil over alleged air pollution violations at dozens of the company's oil and gas facilities on a North Dakota Indian ...

Penguins are vulnerable to exposure to oil spills due to their site fidelity, aquatic lifestyle and near-surface foraging habits. Across their range, penguins have been impacted by chronic and acute oil pollution at sea. The following list includes examples of events where impacts to penguins were documented. It is not exhaustive.
