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 ...
Early symptoms include intoxication, vomiting and abdominal pain. [1] Later symptoms may include a decreased level of consciousness, headache, and seizures. [1] Long term outcomes may include kidney failure and brain damage. [1] Toxicity and death may occur after drinking even in a small amount [1] as ethylene glycol is more toxic than other diols.
Fish acute toxicity syndrome (FATS) is a set of common chemical and functional responses in fish resulting from a short-term, acute exposure to a lethal concentration of a toxicant, a chemical or material that can produce an unfavorable effect in a living organism. [1]
Peterman documented positive effects (improved alertness, behaviour, and sleep) and adverse effects (nausea and vomiting due to excess ketosis). The diet proved to be very successful in children: Peterman reported in 1925 that 95% of 37 young patients had improved seizure control on the diet and 60% became seizure-free.
A purple sea urchin being tested for pollution using a whole effluent toxicity method.. Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.

Fish oil itself is available as a prescription, but the majority of fish oil products available via prescription are derivatives of fish oil. Such products are described elsewhere in this article. These preparations, with the purpose of treating or preventing medical disorder, are only available with a doctor's prescription.
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]
Other conditions that may present similarly include other causes of high anion gap metabolic acidosis such as diabetic ketoacidosis, toxic alcohol ingestion, and starvation ketosis. [2] Toxic alcohol ingestion includes methanol and ethylene glycol poisoning. [6] Pancreatitis, alcoholic hepatitis, and gastritis may also result in similar ...
