It is of interest to document data on the comparative analysis of biomass and clean fuel exposure on pulmonary function during cooking among rural women. The study consisted of 100 biomass and 100 LPG fuel using women with no smoking habits and other related illness Parameters such as FVC, FEV1, FEV1/FVC, PEFR, FEF25-75%were obtained using the computerized spirometry to assess the pulmonary function in these subjects. The collected data were analyzed using the Student t-test method and Pearson correlation. The exposure index for biomass fuel users is 69.78±27.25 showing high exposure duration during cooking. The parameters for pulmonary functions significantly declined in FVC (42.34±13.6), FEV1 (45.55±15.98), PEFR (34.11±14.78) and FEF25-75% (45.56±23.00) for biomass fuel user. However, this is not true for FEV1/FVC ratio (107.56±16.9). The increase in PFT suggests the restrictive and obstructive patterns of pulmonary diseases. There was a negative correlation between increased duration of cooking and the value of FEV1/FVC (r = -0.2961), FEF25-75% (r = -0.3519) and PEFR (r = -0.2868). Thus, the deformation of pulmonary function due to extended exposure of biomass fuel for cooking women in rural Tamilnadu is shown using parameter features such as high exposure index, overcrowded area and improper ventilated houses.

BACKGROUND Around half a million of people still rely on biomass fuels for cooking, which is a major source of household air pollution, associated with increased morbidity and mortality. Biomass smoke exposure is associated with airway obstruction and decreased ventilatory function. Though various studies are available in relation to biomass exposure and pulmonary function, literature is limited on lung age. Hence, the current study was undertaken to evaluate the effect of biomass fuel on pulmonary function and lung age in rural women and correlate biomass exposure index with the spirometry parameters and lung age. METHODS A cross sectional study was conducted in rural areas of Tamilnadu. Around 350 women were screened and 100 women aged > 18 years with biomass exposure for at least five years and able to perform spirometry were selected for inclusion in the study. After obtaining consent, the subjects were evaluated further with detailed history and spirometry to record the lung function parameters and lung age. Biomass exposure index was calculated from hours spent in cooking per day multiplied with the years of cooking. RESULTS Mean age of the participants was 49.88 ± 10.76 years. 68 % had indoor kitchen with inadequate ventilation in 57 % of households. Majority of the women were housewives and belonged to the middle- and low-income groups. Around 19 % were symptomatic with cough and expectoration being predominant symptoms. Spirometry was abnormal in 83 % of the women and showed obstruction in majority. Mean forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), forced expiratory flow 25 - 75 % (FEF) and peak expiratory flow (PEF) were reduced in the study population. A significant negative correlation was observed between the biomass exposure index (BEI) hour-years and FEV 1 and FEF 25 % - 75 %. A significant positive correlation was observed between BEI hours-year and lung age. CONCLUSIONS Majority of the women exposed to biomass fuel smoke, though asymptomatic, had abnormal lung function with increased lung age. Intensity of exposure as measured by biomass exposure index correlated significantly with FEV1, FEF 25 - 75 % and lung age. Hence, regular surveillance of the women using biomass fuel for cooking should be done for early identification of respiratory impairment.

Combustion of solid biomass fuel (SBF) releases a high concentration of airborne pollutants, resulting in household air pollution (HAP). HAP is considered as a leading risk factor for the development of various respiratory diseases. The increased exposure to HAP significantly affects the health of the vulnerable population, including the women, elderly, and children who stay indoors for most of the time. Considering this, self-reported respiratory health symptoms were assessed using a standard American Thoracic Society (ATS) questionnaire, whereas lung function capacity of women using SBF, liquefied petroleum gas (LPG) and mix fuels were assessed using a cross-sectional study design. Lung function capacity was examined with help of spirometry. Results suggest that compared with LPG users, SBF and mix fuel users had a relatively high prevalence of phlegm (25.7%), cough (54%), and eye irritation (74.3%). Use of SBF was found to be associated significantly with lower forced expiratory volume in the first second of expiration (FEV1) values ( P < .01). The study concludes that women cooking with SBF and mix fuels have an impact on lung function and increased prevalence of respiratory symptoms. The findings suggest that women who cook using LPG have improved lung function and respiratory health status. Hence, it is suggested to increase the scope of clean fuel programmes such as Pradhan Mantri Ujjwala Yojana (PMUY) by identifying the barriers for the choice of clean fuel uses for household energy.

Urbanization and industrialization lead to the change of land cover from pervious into impervious. This can impact environmental problems such as water quality degradation that affects human health and water ecosystems. The study aimed to develop a regression-correlation model between impervious cover in Ciliwung watershed and water quality indices in Ciliwung river. The correlation-regression model can be used to predict changes in the status of Ciliwung river water quality due to impervious cover changes. Methods of assessing the indices of water quality are CCME-WQI, NSF-WQI, and STORET within the period of 2005-2016. Monitoring locations from the most upstream to downstream are Atta’awun, Katulampa, Kedung Halang, Pondok Rajeg, Panus Bridge, Kelapa Dua, Condet, Kalibata, MT Haryono and Manggarai. Impervious cover data for each water quality monitoring location is processed using ArcGIS Software. Test of correlation significance between percentage of impervious cover and water quality indices using Pearson Correlation test method. The result of correlation test is significantly a strong inverse relationship between impervious cover and water quality indices. The result of regression test is trend line between impervious cover change and water quality indices that can be used to predict the change of water quality status in Ciliwung River.

Background/AimTo study the association between exposure to biomass smoke from cooking fuels andi cataract, visual acuity and ocular symptoms in women.MethodsWe conducted a community-based cross-sectional study among women (≥20 years and without a previous diagnosis of cataract, ocular trauma or diabetes or those taking steroids) from hilly and plain regions of Nepal. Eligible participants received an interview and a comprehensive eye assessment (cataract development, visual acuity test and ocular symptoms). Participants’ data on demographics, cooking fuel type and duration of use, and cooking habits were collected. We addressed potential confounders using the propensity score and other risk factors for ocular diseases through regression analysis.ResultsOf 784 participants, 30.6% used clean fuel (liquefied petroleum gas, methane, electricity) as their primary current fuel, and the remaining 69.4% used biomass fuels. Thirty-nine per cent of the total participants had cataracts—about twofold higher in those who currently used biomass fuel compared with those who used clean fuel (OR=2.27; 95% CI 1.09 to 4.77) and over threefold higher in those who always used biomass. Similarly, the nuclear cataract was twofold higher in the current biomass user group compared with the clean fuel user group (OR=2.53; 95% CI 1.18–5.42) and over threefold higher among those who always used biomass. A higher proportion of women using biomass had impaired vision, reported more ocular symptoms compared with those using clean fuel. Severe impaired vision and blindness were only present in biomass fuel users. However, the differences were only statistically significant for symptoms such as redness, burning sensation, a complaint of pain in the eye and tear in the eyes.ConclusionsCataract was more prevalent in women using biomass for cooking compared with those using clean fuel.
