Abstract

Increased urbanisation throughout South Asia has increased the number and output of the brick kilns that typically surround major cities, but the environmental and health impacts of their atmospheric emissions are poorly understood in Pakistan. We report the negative effects of hydrogen fluoride (HF) emissions from brick kilns near Peshawar, Pakistan on mung bean (Vigna radiata cv. MN 92) and maize (Zea mays cv. Azam). HF air concentrations, and fluoride concentrations of mung bean and maize grains, were greater close to brick kilns than at more distant sites. The 100-grain weight of mung bean and maize close to brick kilns was significantly lower, by about 30% and 45% respectively, than at control sites. These findings, added to evidence of major impacts on local fruit orchards in this area, suggest that fluoride emissions from brick kilns may have a significant impact on pen-urban agriculture in South Asia.
