Soil mercury accumulation and emissions in a bamboo forest in a compact fluorescent lamp Manufacturing Area
Bulletin of Environmental Contamination and Toxicology, 2018Co-Authors: Chan Zhang, Sheng Chun Wu, Jin Zhang, Ming Hung Wong, Peter Christie, Peng LiangAbstract:The role of bamboo forest in soil Hg accumulation and emissions was evaluated by analyzing Hg concentration in soil and plant samples as well as Hg flux between soil and air. THg concentrations in soil samples ranged widely from 28.5 to 860 ng g−1 with a mean value of 153 ± 17.3 ng g−1. Methylmercury concentrations in soil samples from forest soil (FS, 0.94 ± 0.20 ng g−1) were significantly higher (p < 0.05) than from bare soil (BS, 0.54 ± 0.07 ng g−1). The mean foliar THg concentration (178 ± 16.8 ng g−1) was significantly higher (p < 0.05) than those in branches (63.1 ± 7.27 ng g−1) and roots (73.1 ± 16.9 ng g−1), indicating that the major source of Hg in bamboo might be from air deposition. Hg flux from FS (25.6 ng m−2 h−1) was significantly lower (p < 0.05) than that from BS (32.2 ng m−2 h−1). The annual decline in Hg emissions due to the presence of the bamboo forest may reach 6.94 kg.

Mercury speciation, distribution, and bioaccumulation in a river catchment impacted by compact fluorescent lamp manufactures
Environmental Science and Pollution Research, 2016Co-Authors: Peng Liang, Qiongzhi You, Anna Oi Wah Leung, Yucheng Cao, Xinbin Feng, Jin Zhang, Sheng Chun WuAbstract:The influence from the Manufacturing of compact fluorescent lamps (CFL) on mercury (Hg) speciation and distribution in river catchments nearby a typical CFL Manufacturing Area in China was investigated. Water, sediment, river snail (Procambarus clarkii), and macrophyte (Paspalum distichum L.) samples were collected. Total Hg (THg) and methylmercury (MeHg) concentrations in water ranged from 1.06 to 268 ng · L(-1) and N.D. -2.14 ng · L(-1), respectively. MeHg was significantly positively correlated with THg in water. THg and MeHg in sediment ranged from 15.0 to 2480 and 0.06 to 1.85 ng · g(-1), respectively. River snail samples exhibited high concentrations of THg (206-1437 ng · g(-1)) and MeHg (31.4-404 ng · g(-1)). THg and MeHg concentrations in root of P. distichum L. were significantly higher than those in shoot, indicating that THg and MeHg in the plant were mainly attributed to root assimilation. A very high bioaccumulation factor (20.9 ± 22.1) for MeHg in P. distichum L was noted, suggesting that P. distichum L. might have a potential role in phytoremediating MeHg contaminated soil due to its abnormal uptake capacity to MeHg.

Human exposure to mercury in a compact fluorescent lamp Manufacturing Area: By food (rice and fish) consumption and occupational exposure
Environmental Pollution, 2015Co-Authors: Peng Liang, Qiongzhi You, Anna Oi Wah Leung, Yucheng Cao, Xinbin Feng, Jin Zhang, Ming Hung Wong, Chan Zhang, Sheng Chun WuAbstract:To investigate human Hg exposure by food consumption and occupation exposure in a compact fluorescent lamp (CFL) Manufacturing Area, human hair and rice samples were collected from Gaohong town, Zhejiang Province, China. The mean values of total mercury (THg) and methylmercury (MeHg) concentrations in local cultivated rice samples were significantly higher than in commercial rice samples which indicated that CFL Manufacturing activities resulted in Hg accumulation in local rice samples. For all of the study participants, significantly higher THg concentrations in human hair were observed in CFL workers compared with other residents. In comparison, MeHg concentrations in human hair of residents whose diet consisted of local cultivated rice were significantly higher than those who consumed commercial rice. These results demonstrated that CFL Manufacturing activities resulted in THg accumulation in the hair of CFL workers. However, MeHg in hair were mainly affected by the sources of rice of the residents.
