Exposure to oil. Oil spills, as well as daily oil runoff from urbanized areas, can lead to polycyclic aromatic hydrocarbon (PAHs) entering marine ecosystems. Once PAHs enter the marine environment, fish can be exposed to them via ingestion, ventilation of the gills, and dermal uptake. [10] The major route of uptake will depend on the behavior ...
Health and environmental impact of the petroleum industry
The impact on fish caught in the spill has both immediate and longer-term impacts. Immediately, the fish are tainted with oil, and they cannot be used commercially due to safety reasons. Then, the oil can spread and sink below the water's surface. If fish swallow the oil, they are also inconsumable due to the health risk posed to humans. [128]
