Abstract or Description
Steele and Kimbrough assert that "For the two largest companies that operate secondary lead recyclers nationwide, air emissions at their California smelters have dropped from one-half to one order of magnitude from 1991 to 1993." Data quality is a major problem for environmental emissions from lead smelting, battery manufacture, and battery recycling. Steele and Kimbrough rely on data that is not publicly available. Readers can decide for themselves how much confidence to place in data where it is not possible to assess its quality or representativeness
