Toxicity

Toxicology (from the Ancient Greek words τΠξικός toxikos "poisonous" and λόγΠς logos) is a branch of biology, chemistry, and medicine (more specifically pharmacology) concerned with the study of the adverse effects of chemicals on living organisms.[1] It also studies the harmful effects of chemical, biological and physical agents in biological systems that establishes the Toxicology extent of damage in living organisms. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence Toxicology chemical toxicity include the dosage (and whether it is acute or chronic); the route of exposure, the species, age, sex and environment.

Rich and comprehensive visualization of lethal doses of various substances, enabling anyone to explore and compare the strength and lethality of different toxins and chemicals in a swift, clean and coherent fashion

- Includes the median lethal doses(ld50 )of various drugs, foods, animal venoms, natural toxins and much more

- Containing a comprehensive outline of the lethality of various substances, from the most harmless to the deadliest

- Largest graphical scale of its kind, with Toxicology hundreds of labels and a plethora of accompanying illustrations



Most chemicals display a classic dose response curve - at a low dose (below a threshold), no effect is observed.80 Some show a phenomenon known as sufficient challenge Toxicology - a small exposure produces animals that "grow more rapidly, have better general appearance and coat quality, have fewer tumors, and live longer than the control animals". A few chemicals have no well-defined safe level of exposure. These are treated with special Toxicology care. Some chemicals are subject to bioaccumulation as they are stored in rather than being excreted from the body 85 - 90 these also receive special consideration.
