For your better entry test preparation and better Chemistry MCQs preparation, in this section, we are going to post Environmental Chemistry MCQs.
Environmental chemistry is the branch of chemistry which deals with the study of the sources, reactions, transport, effects, and fates of chemical species in the air, soil, and water environments and the effect of human activity on these things.
