High volume air sampler has been used 0.5 HP series motor to suck in the atmospere. Carbon and copper has been discharged by friction of carbon brushes and copper comutator, And discharged particulate quantities were 2.2-2.7 mg/hr and copper quantities were 0.47-0.59 mg/hr.
As copper particulate has been discharged in atmosphere and again caught on the filter of high volume air sampler, atmospheric copper concentration obtained by this instrument is shown abnormal high level.
Thus, paticulate sampling by this instrument is not suitable for atmospheric copper determination.
