    Abstract A better understanding of microcystin elimination in soil will boost the development of effective strategies to mitigate associated contamination. This study addressed the role and mechanism by which earthworm Eisenia fetida take part in the elimination of microcystin-LR (MC-LR) in soil. The degradation kinetics of MC-LR exhibited good fits with the availability-adjusted first-order kinetic model (R² > 0.97), where >71% of the toxin was rapidly eliminated within the initial eight days (t₁/₂ = 2.34–3.07 days). E. fetida significantly accelerated MC-LR elimination, with a less t₁/₂ of 1.09–1.12 days; however, E. fetida did not further improve the final elimination efficiencies on Day 29 (82.59–93.57% with E. fetida vs. 82.96–92.34% without E. fetida). In soil, E. fetida accelerated MC-LR elimination mainly via biodegradation arising from elevated total organic carbon, enhanced enzyme activities (urease and sucrase) and ameliorations of bacterial bioactivity, diversity and abundance. Indigenous bacteria of Methylophilus and Methylovorus, as well as earthworm-derived Flavobacterium, were considered as potential bacterial degraders for MC-LR. These findings elaborate on the variations in soil properties and soil bacterial community structure and diversity that occurs during MC-LR elimination and lay a foundation for controlling MC-LR contamination in the soil environment.

    Abstract Road dust, household total suspended particulate matters (TSP) and PM2.5 were collected in urban area of Guangzhou, south of China, to investigate the concentrations of total mercury (THg) and methyl mercury (MeHg). The household PM2.5 concentrations varied between 16.2 and 623μg/m3. The average PM2.5 level (174μg/m3) from all of the locations exceeded 24-h concentration from WHO air quality guideline The average concentrations of THg and MeHg were: 235μg/kg and 0.392μg/kg in road dust, 600μg/kg and 1.49μg/kg in TSP; 1006μg/kg (104pg/m3) and 1.40μg/kg (0.134pg/m3) in PM2.5. Risk assessment showed that the Hazardous quotients (HQs) of exposure to Hg and MeHg via road dust and TSP were less than 1, indicating that no adverse risk was manifested. Ingestion of dust was found to constitute a relatively minor pathway of Guangzhou residents′ exposure to Hg. Furthermore, human hair samples from 88 Guangzhou citizens were also analyzed to investigate the mercury accumulation in human body in Guangzhou. The average concentrations of THg and MeHg in human hair samples were 869±831μg/kg and 104±108μg/kg respectively. However, no significant correlations of the mercury species were noted between human hair and road dust, TSP and PM2.5.

    Abstract Organic pollutants, heavy metals and pharmaceuticals are continuously dispersed into the environment and have become a relevant environmental emerging concern. In this study, a situ assay to assess ecotoxicity of mixed pollutants was carried out in three typical sites with different priority contaminations in Guangzhou, China. Chemical analysis of organic pollutants, metals and quinolones in three exposure sites were determined by GC-ECD/MS, ICP-AES and HPLC, as well as, a combination of biomarkers including: ethoxyresorufin O-deethylase (EROD); aminopyrine N-demethylase (APND); erythromycin N-demethylase (ERND); glutathione S-transferase (GST); malondialdehyde (MDA); CYP1A; and P-glycoprotein (P-gp) mRNA expressions were evaluated in Mugilogobius abei. Results of chemical analysis in sediment samples revealed that the dominant chemicals were organic pollutants and heavy metals in Huadi River while quinolones in the pond. Bioassays indicated that differences among sites were in relation to some specific biomarkers. EROD and GST activities significantly increased after 72 h in situ exposure, but no difference was observed among the exposure sites. APND, ERND and MDA exhibited dissimilar change patterns for different priority pollutants. CYP1A and P-gp mRNA expressions were significantly induced at all exposure sites, whilst P-gp activity was typical for S2 with the highest levels of quinolones. The molecular biomarkers seemed to be more susceptible than enzyme activities. These assays confirmed the usefulness of applying a large array of various combined biomarkers at different levels, in assessing the toxic effects of mixed pollutants in a natural aquatic environment.
