Results were obtained for arsenic, cadmium, chromium, cobalt, copper, lead, nickel, and zinc.
It gave off great clouds of toxic smoke, heavy with sulphurous acid gas and tinged with arsenic.
The heavy metals in the ash included arsenic, cadmium, chromium, manganese, nickel, cobalt, copper, zinc, and lead.
As a consequence, the produced white arsenic a#ects red copper by turning it into the white alloy of copper-arsenic.
There were burns that contained wood that did not have high arsenic, chromium, and copper readings (burns 11, 12, 14, 15, and 19).
Second, elemental arsenic does not combust with copper in alloying as in the case of arsenic sulfide.
The highest readings of arsenic, chromium, and copper all occurred when wood was present.
Further correlations existed between heavy metals in the ash for: arsenic and chromium; and arsenic and manganese.
