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 ...
Acute toxicity symptoms have been reported and the study of long-term medical and psychological effects is ongoing. [1] As the largest marine oil spill in history, the potential for physical, psychological, and socioeconomic difficulties and long term effects remain unknown.
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]
The species most commonly claimed to be capable of producing this kind of toxicity include several species from the genus Kyphosus, including Kyphosus fuscus, K. cinerascens, and K. vaigiensis. [1] It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet, but a dietary origin may be more likely.
They may induce hallucinogenic effects similar to LSD (lysergic acid diethylamide) if eaten. [5] However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations ...
Fish oil supplements. A 2023 CDC report found that 58.5 percent of adults had used at least one dietary supplement in the last 30 days from 2017 to March 2020. However, you don't have to look much ...
