      Abandoned Mercury Mining Region in China.

AB  - Dragonflies (Order Odonata) often are considered to be biosentinels of 
      environmental contamination, e.g., heavy metals and/or persistent organic 
      pollutants (POPs). Dragonflies (n = 439) belonging to 15 species of 8 genera were 
      collected from an abandoned mercury (Hg) mining region in China to investigate 
      the bioaccumulation of total Hg (THg) and methylmercury (MeHg). THg and MeHg 
      concentrations in dragonflies varied widely within ranges of 0.06-19 mg/kg 
      (average: 1.5 +/- 2.2 mg/kg) and 0.02-5.7 mg/kg (average: 0.75 +/- 0.65 mg/kg), 
      respectively. THg and MeHg were positively correlated with bodyweight (THg: 
      r(2) = 0.10, P = 0.000; MeHg: r(2) = 0.09, P = 0.000). Significant variations 
      were observed among species, with the highest MeHg value (in Orthetrum 
      triangulare) was fivefold higher than the lowest (in Pantala flavescens). These 
      variations were consistent with those of nitrogen isotope (delta(15)N) values, 
      indicating that increased delta(15)N, i.e., trophic levels, may reflect increased 
      exposure and uptake of biomagnifying MeHg in dragonflies. A toxicological risk 
      assessment found hazard quotients for specialist dragonfly-consuming birds of up 
      to 7.2, which is 2.4 times greater than the permissible limit of 3, suggesting a 
      potential toxicological risk of exposure.
