A recent comprehensive study conducted by researchers at the Indian Institute of Technology (IIT)-Mandi has shed light on the alarming health risks associated with traditional cooking practices in the rural areas of Assam, Meghalaya, and Arunachal Pradesh. The study, conducted in collaboration with the Institut National de Recherche et de Sécurité (INRS), France, and the National Physical Laboratory (CSIR-NPL), highlighted the immediate need for rural communities in the region to switch to cleaner cooking fuels.
In this study, the research team from IIT-Mandi, led by Ph.D. scholar Bijay Sharma and assistant professor Sayantan Sarkar, analyzed the extent and consequences of harmful emissions produced during indoor cooking using firewood and mixed biomass in the three states. The findings revealed that over 50 percent of the rural population in these states still rely on traditional solid fuels, such as firewood and mixed biomass, for cooking, resulting in the release of significant pollutants into the kitchen air.
The researchers quantified the size-resolved concentrations of aerosols and toxic trace metals, as well as carcinogenic organic compounds associated with these particles, during cooking with firewood, mixed biomass, and liquefied petroleum gas (LPG). They also modeled the deposition patterns of these pollutants in the human respiratory system and calculated the resulting inhalation exposure during cooking.
Based on the data collected, the research team estimated the health impact on the rural population, focusing on respiratory diseases such as chronic obstructive pulmonary disease (COPD), pneumonia, and various cancers. The study revealed that exposure to harmful aerosols in kitchens using firewood and biomass was significantly higher compared to LPG-using kitchens. The disease burden faced by the population using traditional fuels was also found to be much higher.
Furthermore, the study highlighted the potential for oxidative stress, which can lead to cell, protein, and DNA damage, among individuals using biomass for cooking. This stress is caused by the inhalation of metals and organic chemicals emitted during indoor cooking with biomass fuel.
In conclusion, this study emphasizes the urgent need for rural communities in Northeast India to transition to cleaner cooking fuels. The researchers recommend measures such as increasing accessibility to LPG, improving cookstove programs, raising awareness in rural areas, funding local solutions, and organizing health camps for rural women. By adopting cleaner cooking practices, these communities can significantly reduce the health risks associated with traditional cooking methods and improve the overall well-being of their population.
