“…Although no previous study exists in which PBDE levels were measured in Korean firefighters’ serum samples, two related studies have been previously carried out in the United States, which equally reported higher levels of PBDEs in firefighters in comparison to the general population, , indicating that there may be more exposure to PBDEs in firefighters’ work environments and fire sites than in the general living environments. In the case of the general population serum samples, the mean concentration recorded in the present study was lower than the mean concentrations of 4.27–17.2 ng/g lw − previously reported for the Korean general population, which may be attributed to the decade-long ban and phase-out of the major PBDE technical mixtures. − …”

This study investigated the occupational exposure of Korean firefighters to a suite of combustion-related pollutants. Exposure to polybrominated diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs) was assessed by measurement of their levels in serum and metabolites in urine (i.e., monohydroxylated PAHs, OH-PAHs). The mean level of ∑PBDEs in the serum of firefighters (17.1 ng/g lipid weight (lw)) was significantly higher than that of the general population (1.39 ng/g lw) (Mann–Whitney U Test, p < 0.05), which is similar to the ∑PAH levels (1286 ng/g lw for firefighters and 1016 ng/g lw for the general population). Individual OH-PAH levels showed 2.1- to 4.2-fold increases in postfire urine samples compared to the control urine samples, with the mean ∑OH-PAHs being significantly higher in postfire urine samples (22,658 ng/g creatinine) than in the control urine samples (10,253 ng/g creatinine) (Mann–Whitney U test, p < 0.05). It was found that ∑PBDEs correlated with firefighters’ length of service and years dedicated to on-site dispatch, while ∑OH-PAHs was strongly associated with firefighters’ exposure duration, age, length of service, and years dedicated to on-site dispatch. Indeed, the results of the present study indicate that Korean firefighters are prone to elevated risk of exposure to toxic combustion-related pollutants compared with the general population.

“…Accordingly, NOEC data that cover aquatic organisms belonging to at least "three phyla and eight families" should be selected (European Chemicals Bureau, 2003;Lu et al, 2018). To provide adequate protection to aquatic organisms, the most sensitive toxicity endpoints including morphology, growth, development, mortality, and reproduction for every species were selected.…”

Ammonia nitrogen (AN) is evaluated with fixed water quality standards (WQSs) in aquatic environment management in China. Since the toxicity of AN can be influenced by water parameters, the current evaluation is not rigorous and may result in problematic conclusions. The present study collected the ecotoxicity and exposure data of AN in Chinese surface freshwaters in 2017. The species sensitivity distribution of AN was established, and the ecological risk posed by AN in Chinese surface waters was assessed with Chinese AN water quality criteria. The results showed that mollusk species are the most sensitive taxa to AN. Ecological risk assessments on AN suggested that, in summer and autumn, when the water temperature and pH are high, the risk of AN may occur at some sites with good water quality (Class II or III). This poses a threat to aquatic organisms at these sites, especially highly sensitive freshwater shellfish. It suggested that neglect of water parameters impact may lead to underestimation of ecological risk of AN in Chinese basins.
