Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
A rather informal terminology of individual toxins relates them to the anatomical location where their effects are most notable: Genitotoxin, damages the urinary organs or the reproductive organs; Hemotoxin, causes destruction of red blood cells ; Phototoxin, causes dangerous photosensitivity; Hepatotoxins affect the liver
Exposure to certain chemicals can cause acute or long-term adverse health effects. Chemical hazards are usually classified separately from biological hazards (biohazards). Chemical hazards are classified into groups that include asphyxiants , corrosives , irritants , sensitizers , carcinogens , mutagens , teratogens , reactants , and flammables ...
Because the available scientific studies provide limited information regarding toxicity and health effects to humans, the increase in use of these chemicals and their effects on human health are ...
However, our research team determined that Fusarium toxins in cannabis potentially pose a greater risk to human and animal health than Aspergillus. Researchers have isolated 16 species of Fusarium ...
A variety of symptoms occur depending on how and where the toxic injuries affect the body. Generally, if the toxins affect the respiratory system the symptoms are coughing, tight chest, difficulty in breathing and nose and throat irritation. Miscarriage or infertility can occur if it occurs in the ovaries or testes. Depression, severe headaches and
The most prominent natural toxin groups that exist in aquatic environments are mycotoxins, algal toxins, bacterial toxins, and plant toxins (8). These marine biotoxins are dangerous to human health and have been widely studied due to their high potential to bioaccumulate in edible parts of seafood.
In hazard identification, sources of data on the risks associated with prospective hazards are identified. For instance, if a site is known to be contaminated with a variety of industrial pollutants, hazard identification will determine which of these chemicals could result in adverse human health effects, and what effects they could cause ...
