“…The sources of PAHs in airborne p cles mainly originate from coal combustion, petroleum, and biomass resulting from w disposal [52]. When comparing sources of PAH pollution in other countries, similar terns were identified [53][54][55][56][57][58]. For instance, in the coastal areas of China, dominant sou of PAH pollution included coal, wood, and straw combustion.…”

“…In Nigeria, PAH sources comprised automobile repair industries, waste dumping, oil spills, and shipbreaking. Similarly, petroleum burning and transport in Iran, biomass burning in Thailand, oil refineries in Iraq, and petroleum combustion in India emerged as major sources of PAH pollution in sediments [54][55][56][57][58]. Overall, global sources of PAH pollution exhibited similarities across most countries, with petroleum contamination being the predominant source in Bangladesh.…”

“…Polycyclic aromatic hydrocarbons (PAHs) are common organic pollutants in sediments worldwide [54][55][56][57][58]. Due to their hydrophobic characteristics, these compounds are settled in the sediment of aquatic environments [53].…”

“…The deposition of PAHs in sediment is a continuous process that can indicate environmental changes in pollutants in sediments over time [59]. In these circumstances, the research on PAHs in sediment can evaluate the PAHs cycles in sediments, historical trends, accumulation, and risks to aquatic ecosystems [50][51][52][53][54][55][56][57][58][59][60]. The studies of PAHs pollution in sediment in Bangladesh suggest that coastal sediment had the highest PAHs concentration compared to urban and river sediments (Table 1).…”

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.
