Modeling the emission sources for polychlorinated biphenyls in India: implications for human health risk assessment.
In addition to the electronic waste generated in India, toxic wastes containing polychlorinated biphenyls (PCBs) are dumped in India for recycling purpose. In addition tropical climate facilitates the rapid entry of PCBs to the atmosphere from the contaminated surfaces. Therefore it is important to identify the pathway for atmospheric PCB loading so as to regulate the ongoing release of PCBs. Hence active and passive air sampling of PCBs were conducted along the urban and suburban transects of seven major Indian cities and from the hotspots and rural/background locations in India during 2006-2012. A sinusoidal model could very well describe the diurnal pattern observed in New Delhi, Kolkata, Mumbai and Chennai, which suggests that concentrations in air are influenced by temperature-dependent air-soil surface exchange processes.
