Description:
Described are the results from studies done to provide test methods for state and local air pollution control agencies to measure accurately the lead emissions from stationary source stacks as required in the National Ambient Air Quality Standard for Lead. Inorganic lead is collected in a standard particulate sampling train, digested with 50% (V/V) nitric acid and 3% hydrogen peroxide and analyzed by atomic absorption spectrometry. The inorganic lead test method was evaluated using baghouse dust samples from a primary copper and a primary lead smelter and stack samples from a lead recovery furnace, a primary battery manufacturing plant, a gray iron foundry and a secondary lead smelter. The alkyl lead method was evaluated using alkyl lead motor mix fluids and samples from an alkyl lead manufacturing plant vent stack.
