[Arsenic contents in native copper].
Determination and comparison of arsenic contents in 11 samples of calcination and pig native copper have been conducted. The results reveal that arsenic contents in pig native copper are about 10 times of those in the calcination samples. Therefore the toxic effect of native copper can be eliminated or reduced.
