“…Many studies have shown that with the development of the economy and the surge in population, increased household and industrial fossil fuel burning (Blumer andYoungblood 1975, Khalili et al 1995), and household heating and cooking (Mastral and Callén 2000), are generally the main sources of PAHs (Burns and Jones 2016, Ko et al 2014, Li et al 2019, Ranjbar Jafarabadi et al 2017. To determine the relationship between economic variables (Yunnan Statistical Yearbook, 2015) and PAH concentration, the correlation and significance of PAH concentration with total population, GDP, coal consumption, and oil consumption were analyzed.…”

The analysis of the correlation between polycyclic aromatic hydrocarbons (PAHs) and economic parameters show that the total population, gross domestic product, coal consumption, and oil consumption have significant relationships with PAH concentrations in Dianchi Lake, Yunnan province, China. An artificial neural network model was developed in order to predict the trend in PAHs concentration in the sediments of Dianchi Lake in the next ten years, based current indicators of economic development. The artificial neural network model estimated the concentration of PAHs for the period 1980 to 2014. The R2 and RMSE of the training samples were 0.97 and 44.2, respectively; the R2 and RMSE of the validation samples were 0.99 and 18.7, respectively the R2 and RMSE of the testing samples were 0.99 and 13.2, respectively; and the R2 and RMSE of all samples were 0.98 and 39.2, respectively. The concentration of PAHs in the sediments of Dianchi Lake predicted by the neural network model shows that the concentration of PAHs from 2021 to 2030 can reach as high as 2128.9 ng/g. The ecological environment of Dianchi Lake has a great impact on the lives of local residents, including through its support for the local economy. Therefore, it is necessary for the government to take more effective measures and increase investments to control the environmental problems in Dianchi Lake.

“…PAHs có thể đi vào cơ thể qua con đường hít thở, tiếp xúc da, cũng như thực phẩm. Một số nghiên cứu đã chỉ ra sự xuất hiện của PAHs trong thực phẩm bao gồm PAHs trong cà phê [8], trái cây và rau quả [9], cá [10], thịt [11] và trong chè [12]… Để đánh giá toàn diện mức độ ô nhiễm các hợp chất này trong thực phẩm, Cơ quan An toàn thực phẩm Châu Âu EFSA năm 2008 đã xác định nhóm PAH4 (BaP + CHR + BaA + BbF) và nhóm PAH8 (PAH4 + BkF + BghiP + DahA + IP) là những PAHs tồn tại trong hầu hết các loại thực phẩm và có chỉ số độc hại lớn, tức là có có khả năng gây ung thư, tăng nguy cơ ung thư [13]. Năm 2015, Uỷ Ban Châu Âu đưa ra quy định mới nhất về mức hàm lượng BaP và nhóm PAH4 tối đa trong một số thực phẩm trong đó có thảo mộc khô với mức 10,0 µg/kg cho BaP và 50,0 µg/kg cho PAH4 [14].…”

Nghiên cứu đã khảo sát quy trình xử lý mẫu và phân tích 15 hợp chất hydrocacbon đa vòng thơm ngưng tụ trong chè bằng phương pháp sắc ký khí ghép nối khối phổ. Giới hạn phát hiện của phương pháp đối với từng PAH trong chè có giá trị trong khoảng 0,07 – 0,16 µg/kg, hiệu suất thu hồi đạt từ 53 – 132 % với độ lặp tốt (RSD từ 1,1 – 7,3 %). Quy trình đã được áp dụng vào phân tích một số mẫu chè xanh của Việt Nam, cho kết quả tổng hàm lượng PAHs trong khoảng 38,1 – 123 µg/kg. So sánh với quy định của Uỷ Ban Châu Âu về hàm lượng tối đa cho phép của benzo(a)pyren và nhóm PAH4 trong thảo dược khô cho thấy tất cả các mẫu chè xanh đã phân tích đều có hàm lượng PAH độc hại ở mức thấp hơn giới hạn cho phép.

“…Coral reefs are productive and highly biodiverse shallow‐water ecosystems that are essential for the survival of several organisms (Y. Li et al., 2019; Ranjbar et al., 2018). However, the influence of organic contaminants on them has become one of the most important factors bringing about their bleaching (Y. Li et al., 2019; Xiang et al., 2018). As coral reefs in the South China Sea are not directly affected by coastal contaminant sources, such as runoff and industrial sewage, the main nonpoint source of PAHs in this area may be atmospheric inputs.…”

In this study, we collected gas, particulate, and surface water‐dissolved phase samples from 16 sites in the South China Sea from March 21 to April 12, 2018. Thereafter, all the samples were analyzed for the air‐water exchange and source apportionment of polycyclic aromatic hydrocarbons (PAHs). Thus, it was observed that the overall PAH concentrations in the water and gas phases were 8.0 ± 5.5 ng/L and 41.3 ± 24.7 ng/m3, respectively. Back trajectory simulation showed that the air masses in the South China Sea primarily originated from mainland China during the heating period, and air‐water exchange analysis showed net deposition from air to water, with fluxes ranging from −5.53 to −89.72 ng/m2/d. Further, the logarithmic gas‐particle partitioning coefficient (logKp) of the PAHs regressed linearly with the logarithmic subcooled liquid vapor pressure (log P0 L), with an average slope of −0.3 ± 0.13.
