摘要

Cooking is a significant source of indoor air pollution (IAP) and is associated with significant morbidity and mortality. Liquefied petroleum gas (LPG; predominant cooking fuel of urban India), though safer than solid fuels, emits significant concentration of fine particles, NOx and several other pollutants, which may trigger respiratory ailments. Effect of exposure to pollutants, generated from fuel combustion and cooking activities, on subjects of differentmicroenvironments has been assessed by carrying out a health survey using a questionnaire and by conducting spirometry. A significant increase in prevalence of cough and impairment of lung functions has been found among cooks compared to non- cooks. A significant difference in prevalence of cough between smoker and nonsmoker non- cooks but no such difference in cooks suggests that kitchen pollutants and smoking have similar effects on respiratory system. Comparison of lung functions (average FEV1% predicted and average FVC% predicted) of cooks (90.6% and 82.6%) and non- cooks (93.7% and 86.2%) shows a significant difference in certain categories. The study brings out a close association between different kitchen microenvironments and specific respiratory parameters, signifying short- and long- term impairment. The impairment is prevalent in both rural and urban Indian cooks, signifying that fuel usage (biomass and LPG) and cooking practices play a prominent role in affecting respiratory health.
