Radioactive contamination refers only to the presence of the unintended or undesirable radioactivity, and gives no indication of the magnitude of hazard involved. less

Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses. Workers in other industries are at risk for exposure as well.The organochlorines and anticholinesterase compounds are responsible of the toxics effects

Arsenic interferes with cellular longevity by allosteric inhibition of an essential metabolic enzyme. Symptoms of arsenic poisoning include headache, confusion, convulsion, diarrhoea, vomiting, and in severe cases coma and death. Routes of exposure include contaminated water, air, and food. Occupational exposure to arsenic may occur with copper or lead smelting and wood treatment and among workers involved in the production or application of pesticides. less

Mercury poisoning can result in several diseases, including acrodynia (pink disease), Hunter-Russell syndrome, and Minamata disease.Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure.The consumption of fish is by far the most significant source of ingestion-related mercury exposure in humans and animals, although plants and livestock also contain mercury due to bioaccumulation of mercury from soil, water and atmosphere, and due to biomagnification by ingesting other mercury-containing organisms.Exposure to mercury can occur from breathing contaminated air,[6] from eating foods which have acquired mercury residues during processing,from exposure to mercury vapor in mercury amalgam dental restorations, and from improper use or disposal of mercury and mercury-co less

Lead interferes with a variety of body processes and is toxic to many organs and tissues including the heart, bones, intestines, kidneys, and reproductive and nervous systems. It interferes with the development of the nervous system and is therefore particularly toxic to children, causing potentially permanent learning and behavior disorders. Symptoms include abdominal pain, confusion, headache, anemia, irritability, and in severe cases seizures, coma, and death.
Routes of exposure to lead include contaminated air, water, soil, food, and consumer products. Occupational exposure is a common cause of lead poisoning in adults. One of the largest threats to children is lead paint that exists in many homes, especially older ones; thus children in older housing with chipping paint are at greater risk. less
