||A study of respirable versus nonrespirable copper and zinc oxide exposures at a nonferrous foundry
||Nov. 1994, Vol.55, No.11, p.1047-1050. 27 ref.
||Personal air samples were collected from workers involved in the casting of a 70% copper and 30% zinc alloy. Samples were taken using 10mm nylon cyclones to categorize aerosols into respirable and nonrespirable fractions. Most of the copper (94%) and zinc oxide (65%) particulate matter collected was nonrespirable. On the whole, a larger proportion of samples of total particulate matter exceeded the OSHA PEL for these substances as fumes than did samples of respirable fractions. It is recommended that air monitoring should include particle size differentiation when comparing results to health standards for fumes or respirable dusts.
