Soman was the third of the so-called G-series nerve agents to be discovered along with GA (tabun), GB (sarin), and GF (cyclosarin). When pure, soman is a volatile, corrosive, and colorless liquid with a faint odor like that of mothballs or rotten fruit. [3] More commonly, it is a yellow to brown color and has a strong odor described as similar ...
Lead is a potent neurotoxin whose toxicity has been recognized for at least thousands of years. [97] Though neurotoxic effects for lead are found in both adults and young children, the developing brain is particularly susceptible to lead-induced harm, effects which can include apoptosis and excitotoxicity. [97]
Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
Developmental toxicity is any developmental malformation that is caused by the toxicity of a chemical or pathogen. It is the structural or functional alteration, reversible or irreversible, which interferes with homeostasis , normal growth , differentiation , development or behavior.
The starting compound studied by the United States was the carbamate EA-1464, of notorious toxicity. [34] Compounds similar in structure and effect to EA-1464 formed a large group, including compounds such as EA-3990 and EA-4056. [34] The Family Practice Notebook claims carbamate-based nerve agents can be three times as toxic as VX. [35]
Organophosphate poisoning is poisoning due to organophosphates (OPs). [4] Organophosphates are used as insecticides , medications, and nerve agents . [ 4 ] Symptoms include increased saliva and tear production, diarrhea , vomiting, small pupils , sweating, muscle tremors, and confusion. [ 2 ]
Beyond their acute toxicity, long-term exposure to organophosphates is associated with a number of heath risks, including organophosphate-induced delayed neuropathy (muscle weakness) and developmental neurotoxicity. [28] [43] [44] There is limited evidence that certain compounds cause cancer, including malathion and diazinon. [45]
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.
