Title: Mercury and methylmercury contamination in fish from Yongxing Island and human health risk evaluation
Abstract: Concentrations of mercury and methylmercury in the muscles of thirty-one fish belonging to four different species( Parupeneus chrysopleuron,Scarops rubroviolaceus,Chlorurus bowersi and Lethrinus atkinsoni) from Yongxing Island were determined. Human health risk assessment model suggested by US EPA was employed to evaluate the mercury pollution level. The results showed that total mercury concentration in marine fish ranged from 0. 002 × 10-6to 0. 474 × 10-6and methylmercury concentration in marine fish ranged from 0. 001 × 10-6to 0. 403 × 10-6. On average,methylmercury accounted for 82. 51% of total mercury. The present distribution trend of total mercury and methylmercury levels in marine fish was in the sequence of carnivorous omnivorous herbivorous. The human risk assessment showed that mercury in carnivorous fish( P. chrysopleuron and L. atkinsoni) would pose potential health risks to human through fish consumption.
