Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [ 2 ] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance.
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).
Six types of toxicity data are included in the file: Primary irritation; Mutagenic effects; Reproductive effects; Tumorigenic effects; Acute toxicity; Other multiple dose toxicity; Specific numeric toxicity values such as LD 50, LC 50, TDLo, and TCLo are noted as well as species studied and the route of administration used. For all data the ...
Although acute or less observable chronic poisoning can also occur in non-target organisms (secondary poisoning), including the humans who apply the biocides and other beneficial organisms. [14] For example, the herbicide 2,4-D imitates the action of a plant hormone, which makes its lethal toxicity specific to plants. Indeed, 2,4-D is not a ...

In adults, a dose of 6 grams a day over the preceding 48 hours could potentially lead to toxicity, [20] while in children acute doses above 200 mg/kg could potentially cause toxicity. [24] Acute paracetamol overdose in children rarely causes illness or death, and it is very uncommon for children to have levels that require treatment, with ...
Factors that influence chemical toxicity include the dosage, duration of exposure (whether it is acute or chronic), route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices.
If left untreated, acute iron poisoning can lead to multi-organ failure resulting in permanent organ damage or death. [ 1 ] Iron is available over the counter as a single entity supplement in an iron salt form or in combination with vitamin supplements and is commonly used in the treatment of anemias .
