“…In the aquatic environment, PAH derivative and PAH concentrations are usually at ng L −1 levels [5,9]; thus, DGT devices need to be deployed for long periods in order to accumulate the measured compounds at detectable levels. The masses of the four compounds measured by the XAD18-DGT device increased linearly with deployment time (12-168 h) (SI Figure S4) and were in good agreement with the theoretical values predicted by Equation (1).…”

“…Compared to pyrene, the NPAH 1-nitropyrene exhibits a higher carcinogenicity and mutagenicity/genotoxicity in in vitro and in vivo tests [7,8]. A study in Brazil showed the mutagenicity of OPAHs in particulate matter samples increased approximately fourfold compared to their corresponding PAHs [9,10]. ClPAHs, which are structurally similar to dioxins and polychlorinated biphenyls (PCBs), are a type of highly toxic organochlorine compound [11][12][13].…”

Polycyclic aromatic hydrocarbon (PAH) derivatives are widely present in the environment, and some are more hazardous than their parent PAHs. However, compared to PAHs, PAH derivatives are less studied due to challenges in monitoring as a result of their low concentrations in environmental matrixes. Here, we developed a new passive sampler based on diffusive gradients in thin films (DGT) to monitor PAH derivatives and PAHs in waters. In the laboratory study, the XAD18-DGT device exhibited high adsorption rates and was demonstrated to be suitable for deployment in environmental waters on the timescale of months. The diffusion coefficients, D, were 5.30 × 10−6 cm2 s−1, 4.51 × 10−6 cm2 s−1, 4.03 × 10−6 cm2 s−1 and 3.34 × 10−6 cm2 s−1 for 9-fluorenone (9-FL), 1-chloroanthraquinone (1-CLAQ), 9-nitroanthracene (9-NA) and phenanthrene (Phe), respectively, at 25 °C. The DGT device’s performance was independent of pH, ionic strength, deployment time and storage time, indicating it can be widely used in natural waters. In the field study, the target pollutant concentrations measured by the DGT are in good accordance with those determined via grab sampling. Then, the DGT devices were utilized to quantify PAH derivatives and PAHs in several rivers in Hefei, China. This work demonstrates the feasibility of using the DGT technique to detect trace PAH derivatives and PAHs in waters.

“…The lower Log K ow values and higher polarity of SPAHs compared with those of PPAHs make them more water-soluble, which increases their mobility and bioavailability. , Hung et al verified that NPAHs occurred in some river water samples at relatively low levels (5.2–7.5 ng/L).

Polycyclic aromatic compounds (PACs) are widely present in aquatic environments and have attracted considerable attention because of their potential carcinogenicity, teratogenicity, and mutagenicity. However, compared with that of the 16 Environmental Protection Agency (EPA) polycyclic aromatic hydrocarbons (PAHs), information on the occurrence and ecological risks of other PACs is scarce. In this study, a liquid− liquid extraction coupled gas chromatography−tandem mass spectrometry method was established for the simultaneous analysis of 80 PACs, including 23 parent PAHs (PPAHs) and 12 alkylated, 10 oxygenated, 8 nitrated, 18 halogenated, and 9 heterocyclic PAHs, in 15 surface water and 7 industrial effluent samples collected from the upper reaches of Yangtze River. The average concentration of total PACs in surface water was 1106.4 ng/L, with ΣHPAH (974.2 ng/L) > ΣPPAH (55.6 ng/L) > ΣAPAH (48.1 ng/L) > ΣNPAH (16.8 ng/L) > ΣOPAH (10.9 ng/L) > ΣXPAH (0.8 ng/L). The average concentration of total PACs in industrial effluent was 373 ng/L with ΣHPAH (294.1 ng/L) > ΣPPAH (37.2 ng/L) > ΣAPAH (23 ng/L) > ΣOPAH (10.9 ng/L) > ΣOPAH (6.7 ng/L) > ΣXPAH (1.1 ng/L). Notably, indole concentrations up to 6466.9 and 1616.6 ng/L were detected in surface water and industrial effluent, respectively. Ecological risk assessment using the risk quotient (RQ) showed that all surface water samples exhibited high risks (RQ > 1), mainly derived from indole, 1,4-naphthoquinone, and PPAHs with high ring numbers. Additionally, 4 surface water samples exhibited medium to high risks, and 10 exhibited low to medium risks based on the total toxicity equivalent (TEQ carc ) evaluation, with the main contribution from benzo[a]pyrene. The results of this study would provide valuable data to comprehensively assess the exposure levels and risks of PACs.
