Chronic pulmonary effects are tbe exception rather the rule in these cases.

The treatment of all oases are discussed under tbe headings: preventive treatment, treatment after akin contact, and treatment after the lesion develops. Treatment after skin symptoms and course of poisoning. Acute poisoning is caused chiefly through the stomach; however, it abo oc curs through the respiratory tract and tltc skin. In chronic poisoning it is absoriwd princi|>aliy through the respiratory system but also through the akin and stomach. AnesicItcaring dust is the most dangerous of all.
