“…In addition to other processing methods, several alternative products are offered to the consumers by improving the taste and aroma of sawdust through the volatile compounds released from the wood or sawdust in the smoking process [ 5 ]. Despite these benefits, as an undesired result of smoking, toxic chemicals such as polycyclic aromatic hydrocarbons (PAH), nitrosamines, heterocyclic amines, and heavy metals are generated due to the pyrolysis of wood lignin and organic compounds within thermal processes [ 6 ]. Harmful chemicals, especially PAHs and heavy metals, that are formed or accelerated during the smoking process threaten human health through the consumption of smoked food products [ 7 ].…”

Fish are vulnerable to environmental pollutants such as polycyclic aromatic hydrocarbon and heavy metals. As one of the most commonly applied processing methods, the smoking of different species has been applied globally. Hence, this study aims to investigate the smoking process on the polycyclic aromatic hydrocarbon and elemental accumulation of the five different species (rainbow trout, Atlantic bonito, horse mackerel, sea bass, and Atlantic bluefin tuna) which are commonly processed and traded in the smoked fish industry. The processing yield, water holding capacity, and pH were also investigated. The results revealed that the proximal differences among fish species influence the water holding capacity, processing yield, and pH which are very important for process sustainability and the quality of the end product. The main finding was the proximal composition impact on the accumulation of both PAHs and heavy metals at different levels. While all of the tested samples were below the maximum permissible limit, some of the heavy metals, especially toxic elements, were found above the acceptable limit. Horse mackerel is determined to be the species most vulnerable to PAHs and heavy metal accumulation.

“…A comparable finding was found at Laizhou Bay in China (Table 4). When comparing PAH concentrations in aquatic organisms with those in other countries, the data strongly indicates a significantly higher accumulation or concentration of PAHs in aquatic organisms in Bangladesh (Table 4) [4,17,32,53,95,[97][98][99][100][101]. This finding suggests a substantial anthropogenic input of PAHs into aquatic ecosystems in the country.…”

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.

“…Additionally, the research noted that higher and medium TOC concentrations in samples were associated with greater mortality and growth inhibition of the ostracod Heterocypris incongruens, underscoring the role of organic matter in modulating PAH toxicity [204]. In the same vein, addressing the detrimental impacts of PAHs on aquatic life, Rezan Rasheed [205] undertook an investigation into the seasonal fluctuations of PAH concentrations in the muscle tissue of catfish (Silurus triostegus) within the Derbendikhan Reservoir, ranking as the second-largest reservoir in the Iraqi Kurdistan region. This study identified a surge in PAH levels during the spring season, a phenomenon attributed to the use of outdated fishing methods and the seasonal variation in water temperatures.…”

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.
