“…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.

“…PAHs xâm nhập vào cơ thể có thể gây ra các bệnh ung thư [5][6][7][8], ảnh hưởng tới DNA [9][10]. Trên thế giới đã có nhiều nghiên cứu đánh giá về sự xuất hiện của PAHs trong môi trường không khí [3,11,12] đặc biệt là trong môi trường nước hồ [13][14][15][16] và trầm tích hồ [17][18]. Tại Tây Ban Nha, nghiên cứu của Hijosa-Valsero và các cộng sự tại một số hồ tại Mediterran cho thầy, nồng độ PAHs rất cao từ 200-1000 ng/l [15].…”

Tóm tắt: PAHs (Polycyclic Aromantic Hydrocacbons) là các hợp chất có khả năng gây ung thư xuất hiện ngày càng phổ biến trong môi trường đất, nước, không khí, trầm tích. Nghiên cứu tiến hành đánh giá hiện trạng nồng độ các hợp chất PAHs trong nước Hồ Tây, thành Phố Hà Nội bằng các phương pháp khảo sát, lấy mẫu và phân tích mẫu, thống kê. Kết quả nghiên cứu cho thấy, nồng độ trung bình của các hợp chất PAHs dao động từ 0,88 ng/l đến 10,34 ng/l. Tổng hàm lượng các chất PAHs từ 1,80 ng/l đến 52,20 ng/l. Nồng độ PAHs tại các điểm quan trắc đều thấp hơn so với tiêu chuẩn của Mỹ (USEPA), Tổ chức Y tế Thế giới (WHO), Cộng đồng kinh tế Châu Âu (EEC). Các hợp chất PAHs chiếm tỉ lệ cao nhất trong số 16 hợp chất PAHs tại Hồ Tây là Naphthalene (21%), Anthracene (17%), Phenanthrene (12%). PAHs có nồng độ cao xuất thiện tại các vị trí có nhiều hoạt động của người dân tại các vị trí quan trắc phía Nam và phía Bắc của Hồ Tây.

“…Exposure to PAHs has the potential to induce various health issues, including numerous categories of cancer and reproductive ailments (Das and Ravi, 2022). The United States Environmental Protection Agency (USEPA) designated sixteen PAHs as priority contaminants based on their abundance and toxicity (Akter et al, 2023;. 7 among the 16 PAHs designated by USEPA were identi ed by the International Agency for Research on Cancer (IARC) as potential carcinogens (Roy et al, 2022).…”

Dust serves as a primary source and reservoir for polycyclic aromatic hydrocarbons (PAHs) in metropolitan areas worldwide. Therefore, this research investigated the pollution levels, origins, and exposure threats linked with PAHs in dust sampled from twenty vehicle parks in Lagos, Nigeria -one of the fastest growing African cities. Diverse PAH origins were identified with positive matrix factorization (PMF) technique and diagnostic ratios. Total PAH concentrations ranged from 4.81 µg/g to 8.48 µg/g. Four-ring PAHs, particularly Fluoranthene (Flan), were the most prevalent, with concentrations ranging from 0.26 µg/g to 1.33 µg/g in Lagos parks. Benzo(k)fluoranthene from road traffic sources, emerged as the leading PAHs among the seven considered cancer-causing PAHs, ranging from 0.31 µg/g to 0.99 µg/g. The PMF model identified eight sources of PAHs, including biomass combustion, gasoline vehicle exhaust, coke oven emissions, lubricating oil burning, unburnt fossil fuel, diesel combustion, petrol combustion, and fugitive dust. Applying the probabilistic cancer risk model, Lagos average cancer risk from chosen vehicle parks was calculated as 1.27 x 10− 5 for children and 1.41 x 10− 5 for adults, falling within acceptable risk levels.
