LD50

LD50 | APES Human Hazards 6 | Scoop.it

LD50 is a measurement used in toxicology studies to determine the potential impact of toxic substances on different types of organisms. It provides an objective measure to compare and rank the toxicity of substances. The LD50 measurement is usually expressed as the amount of toxin per kilogram or pound of body weight. When comparing LD50 values, a lower value is regarded as more toxic, as it means a smaller amount of the toxin is required to cause death.

Hazardous Compounds

Hazardous Compounds | APES Human Hazards 6 | Scoop.it

Depending on the amound of the toxin that a person is exposed to, digests, or touches changes the intensity of the hazards. The most they take in, the worse it is. Also it depends on the organism's resistance to the toxion changes the effect it has. Young and old people immune system is weaker so the toxion will be worse for them because their body cannot fight back as well as someone who is middle aged.

Dose-response relationship - Wikipedia, the free encyclopedia

Dose-response relationship - Wikipedia, the free encyclopedia | APES Human Hazards 6 | Scoop.it

The dose-response relationship, or exposure-response relationship, describes the change in effect on an organism caused by differing levels of exposure (or doses) to a stressor (usually a chemical) after a certain exposure time.

Studying dose response, and developing dose response models, is central to determining "safe" and "hazardous" levels and dosages for drugs, potential pollutants, and other substances to which humans or other organisms are exposed.
