Even after its complete discontinued use, it will still remain in the environment for many more years after because of DDT's persistent attributes. [16] Previous studies have shown that DDT and other similar chemicals directly elicited a response and effect from excitable membranes. [18]
Aluminum is the most common natural metal in the Earth's crust and is naturally cycled throughout the environment via processes like the weathering of rocks and volcano eruptions. [21] Those natural processes release more aluminum into the freshwater environments than do humans, but anthropogenic impact has been causing values to rise above the ...
The term toxungen has also been proposed to refer to toxins that are delivered onto the body surface of another organism without an accompanying wound. [16] 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 ...
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.
Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus. This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications. The human embryo or fetus is ...
Toxins, whether produced by animals, plants, insects, or microbes are generally metabolic products that have evolved as defense mechanisms for the purpose of repelling or killing predators or pathogens." [14] Biocides are classified as oxidizing or non-oxidizing toxicants. [15] Chlorine is the most commonly manufactured oxidizing toxicant. [15]
Common examples of neurotoxins include lead, [7] ethanol (drinking alcohol), [8] glutamate, [9] nitric oxide, [10] botulinum toxin (e.g. Botox), [11] tetanus toxin, [12] and tetrodotoxin. [6] Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive ...
