Poisoning occurs by inhalation of lead dust or vapors. There are household lead poisonings, with the use of jam or pickles stored in an earthenware dish, covered with lead glaze. Lead poisoning in plants is usually chronic.
Lead poisoning – is an example of the most frequent diseases caused by exposure to the environment. In most cases this occurs while up taking of low dose and their accumulation in the body until its concentration reaches a critical level necessary for doxology manifestations.
There is an acute and chronic form of a disease.
The acute form occur when the large doses ingested or inhalation of lead vapor, or in the dispersion of lead paint. Chronic poisoning most commonly occurs in children, licking the surface painted with lead paint.

Chronic poisoning can develop when using poorly burnt ceramic dishes, covered with enamel, containing lead, with the use of contaminated water, especially in older homes where sewage pipes contain lead, with alcohol abuse made in the distiller that contain lead. The problem of chronic poisoning is also associated with the presence of lead vapors in the application of tetraethyl lead for burns as anti-shock drug.
Gaseous emissions is poisoning, not only the atmosphere but also the soil, and water, and food products. Only in North America, such emission into the atmosphere is 200 thousand tons of lead annually. Poisoning of the atmosphere is everywhere, and the average adult gets about 150 to 400 mGy, and the concentration of lead in blood and in tissues up to 25 mgr/100 ml. For the occurrence of clinical signs of disease there should be about 80 mgr/100 ml.
