Smoke Still Spreading Eastward Along Foot of Himalayas, India26.6N 80.3E
Smoke from agricultural fires set by farmers in northwestern India to clear land for the biannual growing season creeps along the foot of the Himalayas and spreads eastward. Although the fires have the benefit of eliminating pests that could harm the crops, the smoke also can harm human health, aggravating heart and lung disease. Older adults, children, and people with chronic health conditions are particularly at risk. The smoke may include thousands of compounds, including carbon dioxide, carbon monoxide, nitrogen oxides, and particulate matter.
