空气污染是对人类安全的最重大威胁之一,因为它对全球健康造成了有害的影响。这项研究使用西孟加拉邦污染控制委员会(WBPCB)运营的81个站点的数据,调查了2016年至2021年西孟加拉邦22个地区的空气污染水平。该研究评估了颗粒物(PM)对人类健康的短期和长期影响。PM10的年度变化最高的是在2016年(106.99±34.17μg/m3),最低的是2020年(88.02±13.61μg/m3),而NO2(μg/m3)的年度变化最高的是在2016年(35.17±13.55μg/m3),2019年最低(29.72±13.08μg/m3)。同样,2017年SO2水平较低(5.35μg/m3),2020年较高(7.78μg/m3)。在国家,Bardhaman,班库拉,加尔各答,和Howrah记录了最高的PM10浓度。污染的月度和季节性变化在12月表现得更高,一月,2月(冬季)和6月最低,七月,8月(雨季)西孟加拉邦南部的污染水平高于北部。由于颗粒物的短期和长期健康影响评估显示,成人慢性支气管炎发病率和儿童支气管炎患病率的估计归因病例数(ENAC)分别为305,234和14,652。PM2.5对人类健康的长期影响ENAC因成人慢性阻塞性肺疾病导致的死亡,0-5岁儿童急性下呼吸道感染,肺癌,成人卒中分别为21,303,12,477,25,064,94,406和86,272.这一结果有助于决策者和利益相关者有效解决指定区域内的空气污染和健康风险问题。
Air pollution is one of the most significant threats to human safety due to its detrimental health consequences worldwide. This study examines the air pollution levels in 22 districts of West Bengal from 2016 to 2021, using data from 81 stations operated by the West Bengal Pollution Control Board (WBPCB). The study assesses the short- and long-term impacts of particulate matter (PM) on human health. The highest annual variation of PM10 was noted in 2016 (106.99 ± 34.17 μg/m3), and the lowest was reported in 2020 (88.02 ± 13.61 μg/m3), whereas the highest annual variations of NO2 (μg/m3) were found in 2016 (35.17 ± 13.55 μg/m3), and lowest in 2019 (29.72 ± 13.08 μg/m3). Similarly, the SO2 level was lower (5.35 μg/m3) in 2017 and higher in 2020 (7.78 μg/m3). In the state, Bardhaman, Bankura, Kolkata, and Howrah recorded the highest PM10 concentrations. The monthly and seasonal variations of pollution showed higher in December, January, and February (winter season) and lowest observed in June, July, and August (rainy season). The southern part of West Bengal state has recorded higher pollution levels than the northern part. The short- and long-term health impact assessment due to particulate matter shows that the estimated number of attributable cases (ENACs) for incidence of chronic bronchitis in adults and prevalence of bronchitis in children were 305,234 and 14,652 respectively. The long-term impact of PM2.5 on human health ENACs for mortality due to chronic obstructive pulmonary disease for adults, acute lower respiratory infections in children aged 0-5, lung cancer, and stroke for adults were 21,303, 12,477, 25,064, 94,406, and 86,272 respectively. This outcome assists decision-makers and stakeholders in effectively addressing the air pollution and health risk concerns within the specified area.
