Environment lead pollution

Patterson felt he had no choice. He would have to focus on lead in the environment. He would have to demonstrate that the preindustrial world had been virtually free of lead pollution. He would have to challenge the giants of American industry carmakers, petroleum companies, lead producers, and chemical corporations.

Organic lead compounds have been introduced into the environment as pollutants, e.g. the fuel additive (anti knocking agent) tetraethyl lead, making it difficult to establish a biogenic origin of related compounds. However, methyl lead compounds, e.g. (CH3)4Pb have been discovered under environmental conditions, which are in accord with the biomethylation of lead [30]. In a comparative study, bioactive sediments methylated mercury, tin and lead substrates. Mercury underwent methylation ca. 10000 times faster than tin and lead, but lead was methylated more readily than tin [31]. 

I have considered lead pollution in detail, but lead is not the only villain in the prenatal environment. Others include methyl-mercury polychlorinated biphenyls (PCBs) dioxins pesticides ionizing radiation and maternal use of alcohol, tobacco, marijuana, and cocaine. These villains can cause a range of behavioral effects from severe mental retardation and disability to subtle changes in mental function that depend on the timing and dose of the chemical agent. Indeed, more than zoo industrial... 

Although lead pollution effectively began early in the history of mankind, the human input of this metal to the environment increased sharply in the twentieth eentury (Fergusson, 1990). For example, the burning of lead-supplemented fuels has caused the release into the atmosphere of huge quantities of lead-containing particles and aerosols (and their subsequent wet and dry deposition in waters and soils). 

Our environment is polluted in many other ways, such as pollution caused by heavy metals, including mercury (Hg), lead, plutonium, cadmium, and so on biological material pollution CO pollution methane pollution benzene and toluene pollution and radon, sulfur, chlorine, and ash pollution. All these pollutants have dire health consequences.
