“…Across various studies on PAHs, sediment in Bangladesh demonstrated a wide concentration range, ranging from 0.006 to 17,089.1 ng/g (16 PAHs priority compounds by USEPA) (Table 1). When comparing PAH concentrations in Bangladeshi sediment with those in other countries, similar levels were observed in the industrial sediment of India and the river sediment of Iraq (Table 1) [24,51,[56][57][58][61][62][63][64][65][66][67][68][69][70]. However, in most other countries, sediment PAHs concentrations were lower than those in Bangladesh, suggesting a higher accumulation or pollution of PAHs in Bangladeshi sediment (Table 1).…”

“…Overall, the PAHs pollution in the sediment of Bangladesh showed that coastal sediment has the highest PAHs concentration compared to river and urban sediments. Moreover, sediment PAHs concentrations are considerably higher than in most other countries [51,[56][57][58][60][61][62][63][64][65][66][67][68][69][70]. The dominant compounds in coastal sediment are the 4-ring PAHs, constituting 52% to 81% of the total concentrations [24].…”

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.

“…Surface sediment in the western and central part of the lagoon revealed higher levels in coastal areas with a main attribution by oil-related activities dating back to the 1800s [147]. Although, recently a comprehensive study indicated petrogenic origin in water and pyrogenic origin of PAHs in sediments, attributed by the difference in distribution of LMW and HMW PAHs in these environmental matrices (Figure 8) [59]. Another study in Northeastern China wetlands, showed that PAHs originated mainly from coal burning and vehicle emissions, with high concentration in industrial areas [148].…”

“…Among organic micropollutants, PAHs are one of the most abundant in freshwater systems and present toxic properties even at low doses, leading to bioaccumulation in fishes [57], invertebrates [7], and algae [58]. The prevalence of PAHs in freshwater systems poses a significant environmental concern, with their discharge into aquatic environments occurring through various pathways, including atmospheric deposition, runoff, and wastewater inputs [59]. Their hydrophobic nature promotes the adsorption of PAHs to suspended sediments in diverse aquatic ecosystems composed by wetlands, rivers, lakes, and estuarine environments [60][61][62].…”

“…A study on a typical constructed wetland specify that PAHs mainly originate from a mix of fossil fuel combustion and petroleum leakage sources, although distribution between sediments and surface water is influenced by molecular weight (Figure 9) [153]. On the other hand, urban wetlands can have diverse sources of PAH pollution, including agricultural practices [154], wastewater discharge [59], and vehicular exhaust emissions [109]. Ashtamudi Wetland, India, was confirmed that petrogenic and pyrogenic origins of PAHs are related to the impact of urban activities.…”

This review paper presents a comprehensive synthesis of current knowledge on the contamination of water systems by polycyclic aromatic hydrocarbons (PAHs). PAHs, organic contaminants characterized by two or more fused aromatic rings, are notably problematic due to their persistence, bioaccumulation, and significant health risks. The review commences with an examination of various sources of PAHs in aquatic environments, encompassing both anthropogenic activities, such as industrial discharges, urban runoff, and oil spills, and natural phenomena including volcanic eruptions and wildfires. Subsequently, the discussion shifts to the distribution patterns of PAHs within different aquatic ecosystems, with an analysis of factors that influence their transport. Considerable focus is placed on the entry mechanisms of PAHs into water systems and their interactions with diverse environmental matrices. Additionally, the ecotoxicological effects of PAHs on aquatic life are scrutinized, with particular emphasis on molecular, individual, and ecosystemic impacts. This includes an exploration of PAH bioaccumulation in aquatic organisms and their potential mutagenic and carcinogenic consequences. The review further addresses the challenges associated with detecting and quantifying PAHs in aquatic settings, reflecting on the advancements in analytical methodologies and the complexities introduced by their varied physicochemical properties. The paper concludes with a summary of existing regulatory frameworks and guidelines governing PAH contamination in water systems, underscoring the imperative for global collaboration in the monitoring and management of PAH pollution.
