Assessing air quality of the recycled steel industries and associated health risks in a mega port city of Southeast Asia
Chittagong, the port city of Bangladesh, has become a major hub for the world’s shipbreaking industry, ideally suited for developing shipbreaking yards and recycled steel industries. This study aimed to evaluate the air quality of recycled steel industries in Chittagong. Formaldehyde (HCHO), total volatile organic compounds (TVOC), and Particulate matter (PM2.5, PM10) were investigated from three shipwrecking yards and five sites in the city near the recycled steel industries. The mean concentrations of HCHO ranged from 204.50 to 463.67 µg m-3, TVOC 326.67–2391.33 µg m-3, PM2.5 ranged from 125.17 to 226.67 µg m-3, and PM10 ranged from 162.33 to 276.60 µg m-3 in the air near the recycled steel industries. All these values exceeded the recommended chronic exposure limits. Calculated hazard quotient (HQ) and hazard index (HI) values consistently exceeded threshold limit 1, indicating a high risk of adverse health effects for children and adults due to air pollutant exposure. These findings highlight the urgent need for stricter environmental regulations and enforcement to promote sustainable shipbreaking and recycled steel industries that balance economic benefits with environmental and public health protection in Bangladesh.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
