It is harmful for health .
hello,i will help you with this :)
BRIEF EXPLANATION:
*****The combustion of hydrogen sulfide and organosulfur compounds proceeds similarly. For example:!!see below!!
*****2 H2S + 3 O2 → 2 H2O + 2 SO2The roasting of sulfide ores such aspyrite, sphalerite, and cinnabar (mercury sulfide) also releases
*****SO2:[15]4 FeS2 + 11 O2 → 2 Fe2O3 + 8 SO22 ZnS + 3 O2 → 2 ZnO + 2 SO2HgS + O2 → Hg + SO24 FeS + 7O2 → 2 Fe2O3 + 4 SO2A
*****combination of these reactions is responsible for the largest source of sulfur dioxide, volcanic eruptions. These events can release millions of tonnes of SO2.
hope it helps you
pls mark as brainlist :)
