Life Science I need information on lead, cadmium and mercury poisoning and their effects on our bodies. Lead poisoning, also called plumbism, is the deleterious effect of a gradual accumulation of lead in body tissues, as a result of repeated exposure to lead-containing substances. Individual susceptibility to lead poisoning varies widely.
Symptoms also tend to be variable.
They may develop gradually or appear suddenly after chronic exposure. The poisoned individual usually becomes pallid, moody, and irritable and may complain of a metallic taste. Digestion is deranged, the appetite fails, and there may be severe abdominal pain, with spasms of the abdominal muscles and constipation. A black line may appear at the base of the gums. Lead poisoning damages red blood cells and leads to hemolysis with resulting anemia .
