Beryllium poisoning is poisoning by the toxic effects of beryllium, or more usually its compounds. It takes two forms: Acute beryllium poisoning, usually as a result of exposure to soluble beryllium salts; Chronic beryllium disease (CBD) or berylliosis, usually as a result of long-term exposure to beryllium oxide usually caused by inhalation.
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]
In addition to beryllium's toxicity when inhaled, when brought into contact with skin at relatively low doses, beryllium can cause local irritation and contact dermatitis, and contact with skin that has been scraped or cut may cause rashes or ulcers. [3] Beryllium dust or powder can irritate the eyes. [4]
Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.
A cheap fish that may cause severe food poisoning with, shall we say, explosive results, escolar is banned in some countries. While the U.S. permits it, the FDA has issued warnings about its ...
Ciguatera fish poisoning (CFP), also known as ciguatera, is a foodborne illness caused by eating reef fish contaminated with ciguatoxins. [ 4 ] [ 2 ] Such individual fish are said to be ciguatoxic . Symptoms may include diarrhea , vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness , and weakness.
PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable.
The giant moray is a reef fish at the top of the food chain. Like many other apex reef fish, it is likely to cause ciguatera poisoning if eaten. [4] [5] Outbreaks of ciguatera poisoning in the 11th to 15th centuries from large, carnivorous reef fish, caused by harmful algal blooms, could be a reason why Polynesians migrated to Easter Island ...
