“…But there has been no research about the direct exposure risk to PAHs for shipbreaking workers. Several studies suggest that direct exposure to PAHs can lead to carcinogenicity, mutagenicity, developmental dysfunction, and sexual dysfunction in humans [106]. In these circumstances, we argue that subsequent research is needed to evaluate the health risks, including cancer [117], B-cell IgE production [118], DNA damage [119], and human hormonal dysfunction [120] of local residents as well as shipbreaking workers.…”

“…So, we recommend more research on PAHs pollution in rivers and coastal ecosystems in Bangladesh in different environmental compartments such as sediment, water, and aquatic organisms. Moreover, the prospective research directions for PAHs pollution in Bangladesh would be to quantify sources [70], distribution [70], spatial and temporal distribution [65], environmental fate [38], dissolved and particulate phases [106], toxicity [38], sediment core [63], and residue concentrations [107].…”

Polycyclic aromatic hydrocarbons (PAHs) pollution has emerged as a significant environmental issue in Bangladesh in the recent years, driven by both economic and population growth. This review aims to investigate the current trends in PAHs pollution research, covering sediments, water, aquatic organisms, air particles, and associated health risks in Bangladesh. A comparative analysis with PAHs research in other countries is conducted, and potential future research directions are explored. This review suggests that the research on PAHs pollution in Bangladesh is less well studied and has fewer research publications compared to other countries. Dominant sources of PAHs in Bangladesh are fossil fuel combustion, petroleum hydrocarbons, urban discharges, industrial emissions, shipbreaking, and shipping activities. The concentrations of PAHs in sediments, water, air particles, and aquatic organisms in Bangladesh were found to be higher than those in most of the other countries around the world. Therefore, coastal sediments showed higher PAHs pollution than urban areas. Health risk assessments reveal both carcinogenic and non-carcinogenic risks to residents in Bangladesh due to the consumption of aquatic organisms. According to this investigation, it can be concluded that there are considerably higher PAHs concentrations in different environmental compartments in Bangladesh, which have received less research attention compared with other countries of the world. Considering these circumstances, this review recommends that future PAHs pollution research directions should focus on aquatic ecosystems, shipbreaking areas, air particles, and direct exposure to human health risks. Therefore, this study recommends addressing the identification of PAH sources, bioaccumulation, biomagnification in the food web, and biomarker responses of benthic organisms in future PAHs pollution research.
