Document Summary

There are many subdivisions and categories that play into toxicology. It studies the negative consequences in biological systems caused by chemical/physical agents. You need to look at moa to understand what they are doing and to figure out how to treat them/create a better material. Important factor is risk assessment how much of something can we be exposed to and tolerate it: 2 basic functions: risk assessment and basic science. Toxicants are all around us, prevalent in nature people tend to think of fungi, but most of the plant life around us are toxic (e. g. fox glove plants poisonous) Biological toxins that act on nicotinic receptors: too much activation/blockage is detrimental to the body (i. e. : many wildlife have poisonous effects on nicotinic receptors) Galantamines: floods the synapse with ach dangerous. This is why you cannot survive in the woods without a specialized guide because most plants are extremely poisonous. Atropine: blocks ps found in green berries.
