“…Thus, determining Cd concentrations in different food items and assessing the risk of their potential threat to human health have attracted increasing attention (Copat et al 2012;Chary et al 2008;Mapanda et al 2007;Shao et al 2012;Stewart et al 2011). Although several researchers reported that the Cd dietary intake for residents in selected areas of different countries such as China, Italy, and Chile was considered safe (Beccaloni et al 2013;Yuan et al 2014;Munoz et al 2005;Liu et al 2010;Hu et al 2013), a number of other studies indicated that potential health risks caused by Cd intake exist for people who consume leafy vegetables and rice on a daily basis.…”

A total of 484 rice samples were collected from five polluted areas in China to investigate the cadmium (Cd) contamination of rice and its potential health risks. The mean Cd contents of analyzed rice samples obtained from different areas ranged from 0.149 to 0.189 mg·kg(-1). Cd concentrations in more than 18% of rice samples exceeded the maximum allowable Cd concentration, and the highest level of 41.1% was observed in samples from Hezhang, Guizhou, which was characterized by serious Cd pollution. Target hazard quotient (THQ) values of 1.5 to 7.8 from rice intake indicated a significant non-carcinogenic health risk for humans, particularly for highly exposed consumers. Children are more at risk than adults, as indicated by the higher THQs. Moreover, carcinogenic risks of Cd from rice intake for average and high consumers in the selected areas were two to three and four to eight greater, respectively, than the threshold value recommended by the International Commission on Radiological Protection.

“…Extremely high Hg concentrations in air, up to 16, 000 ng · m −3 , have been reported in CFL manufacturing zone, resulting in a severe exposure of CFL workers to Hg vapor through inhalation (Xu et al 2007). Our previous study has also demonstrated that CFL manufacturing activities may lead to Hg contamination of the local soil and agricultural products (Shao et al 2012). Moreover, elevated concentrations of THg and MeHg in local cultivated rice samples were observed when compared with the commercial rice samples from the markets.…”

“…The percentage of MeHg to THg in the river snails accounted for only 14.6-37.6%. Shao et al (2012) reported that THg and MeHg concentrations in fish from the local market in Gaohong, and ranged from only 14 to 170 and from 11 to 143 ng · g −1 , respectively; which were significantly lower than those in the river snails that lived in sediment. Furthermore, THg and MeHg concentrations in fish samples from the abandoned Hg mines in China ranged from 61 to 680 and from 24 to 98 ng · g −1 , respectively ).…”

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.

“…In areas of the upper Songhua River, the concentration of MeHg was 0.04-0.45 mg/kg (Wang et al, 2005). In sediment samples around compact fluorescent lamp factories in the province of Zhejiang, China, the concentration of MeHg was 0.03-1.02 mg/kg (Shao et al, 2012). Because specific F oc values were not available for these studies, we were unable to obtain the RQ values.…”

Mercury (Hg) exists in different chemical forms presenting varied toxic potentials. It is necessary to explore an ecological risk assessment method for different mercury species in aquatic environment. The predicted no-effect concentrations (PNECs) for Hg(II) and methyl mercury (MeHg) in the aqueous phase, calculated using the species sensitivity distribution method and the assessment factor method, were 0.39 and 6.5 × 10 −3 μg/L, respectively. The partition theory of Hg between sediment and aqueous phases was considered, along with PNECs for the aqueous phase to conduct an ecological risk assessment for Hg in the sediment phase. Two case studies, one in China and one in the Western Black Sea, were conducted using these PNECs. The toxicity of mercury is heavily dependent on their forms, and their potential ecological risk should be respectively evaluated on the basis of mercury species.
