The most abundant ore is galena, in which lead is present as the sulfide (Pb$), and from which metallic lead is readily smelted.

Bipod lead determinations represent the most effective way to Monitor an individual for exposure to lead* Blood lead levels exceeding 60-8G ug Pb/100 g of blood indicate overexposure to lead, A blood lead limit pf 50 ug Pb/100 g blood was also continued.

The personal air monitor study was conducted to determine the relationship between air lead levels and blood lead levels with the air lead being measured using personal air monitors.

The blood levels of lead were higher in rats treated with lead acetate compared to the controls (lead-treated rats 40.4 1.4 fig/ dl, control rats 2.2 0.3 pg/dl; P < 0.05).

Food lead increased and lead paint exposure changed little.

Lead in gasoline the only other widespread source of lead exposure (other than occupational) is from leaded gasoline, the amount of lead used in gasoline production across the nation is available from the quarterly refiner

Central nervous system effects caused by lead exposures are usually due to the ingestion or inhalation of large amounts of lead, and an increase in the concentration of lead in the blood would have been detected before the symptoms could have been experienced, if they are to be attributed to lead exposure.

For our part, the Lead Industries Association intends to keep you apprised of any new developments and issues related to lead and the lead industry through future mailings.

Stationary sources included in the study are primary and secondary lead smelters, a primary lead refinery, battery plants and the only remaining tetraethyl lead production plant.
