Mohit Saxena,Sudhir Kumar Sharma,Nidhi Tomar,Humaira Ghayas,A. B. Sen,Rohtash Singh Garhwal,N. C. Gupta,Tuhin Kumar Mandal +7 more
TL;DR: In this article, the authors determined the emission factors (EF) and estimated the emission of particulate matter (PM), organic carbon (OC), elemental carbon (EC), polycyclic aromatic hydrocarbons (PAHs), water soluble inorganic constituents (WSIC), and trace gases such as SO_2, NO and NO_2 from the combustion of biomass fuels (FW: fuel wood and DC: dung cake) used in rural sectors for cooking over Himachal Pradesh (HP), representing the Northwestern Himalayan region of India.
