What is Indoor air pollution in rural north-east India: Elemental compositions, changes in haematological indices, oxidative stress and health risks about?

Chronic smoke exposure, emitted by biomass fuel burning leads to many diseases, which are originated due to oxidative stress. The present study investigated the levels of PM, PM and PM bound trace metals released during cooking with fuelwood and subsequent changes in haematological parameters along with oxidative stress in rural tribal women of northeast India exposed to wood smoke. The levels of PM, PM and trace metals associated with PM (nickel, cobalt, manganese, zinc, cadmium, lead and copper) were measured. In addition, blood samples were analyzed for concentrations of different blood related parameters (haemoglobin, platelet count, red blood cells and white blood cells) and levels of antioxidants (reduced glutathione, superoxide dismutase, and catalase). Plasma malondialdehyde (MDA) was measured as a biomarker of lipid peroxidation. Health risk assessment was done to assess the potential risk posed by inhalation of fine particles emitted from cooking with fuel wood. Levels of both PM and PM were higher in wood users compared to LPG users during cooking period (644.4 ± 368.3 μg/m3 vs 50 ± 23.8 μg/m3; 915 ± 441.3 μg/m3 vs 83.3 ± 33 μg/m3) and it exceeded the permissible limits
