Over a wide range of lead ingestion, urinary lead excretion remains constant, although renal lead content Increases.

In the first place nearly 1*0 per cent of all the lead used last year wont into chemical compounds like white lead, red lead, litharge, black oxides, lead silicates, lead chromates, and tetraethyl lead, to name only the more important few. , The other 60 per cent of the load consumed is largely in metallic form either as pure lead or as alloys.

About 60 to 70 percent of tho weight of a battery is lead and this lead is about equally divided between metallic anti monial lead and lead oxide.

The prevention of overt symptoms of lead poisoning such as lead encephalopathy, peripheral neuropathy, severe anemia, or lead cramps by reducing existing lead accumulation in these individuals is also prophylaxis.
