Every morning and evening, millions of women in India spend an hour or two cooking their rice, dal, curry, and roti or other flat bread. Most will prepare their meals over a smoky, 3-stone open fire or a traditional clay or brick cook stove called a chulha.

Based on established linkages between ferrimagnetism and heavy metal concentration of anthropogenic particulates, we attempt here to delineate pollutant residing domains and study the role of surface runoff and
wind circulations over its redistribution in the Pune Metropolitan Region (PMR) in Maharashtra.

The grey, sulphur-laden skies overlying parts of Asia have a bright side — they reflect sunlight back into space, moderating temperatures on the ground. Scientists are now exploring how and where pollution from power plants could offset, for a time, the greenhouse warming of the carbon dioxide they emit.
