Lead is a toxic metal. Exposure is usually via inhalation of fumes, vapour or dust.
Symptoms of exposure include headaches, tiredness, irritability, constipation, nausea, stomach pains, anemia and weight loss. Prolonged exposure can cause damage to kidneys, nervous system and brain.
Unborn children are a particular concern, so any woman of child baring age must take particular care if exposure is possible.
Tests of concentration in blood can pick up exposure.
