The results show that total mercury (T-Hg) and methyl mercury (Me-Hg) in Locusta migratoria manilensis and Acrida chinensis are 0.032 - 0.402 mg x kg(-1), 0.023 - 0.362 mg x kg(-1) and 0.003 - 0.031 mg x kg(-1), 0.004 - 0.015 mg x kg(-1) while the proportion of Me-Hg to T-Hg are 3.5% - 49.7% and 2.0% - 44.4%. T-Hg in arthropods is higher than that a magnitude in non-polluted areas. As primary consumers, mercury contents in Locusta migratoria manilensis and Acrida chinensis are lower than plants they eat. That is not consistent with the non-polluted areas. Paratenodera sinensis is the second consumer and there is an obvious mercury accumulation in it. For Locusta migratoria manilensis, T-Hg decreased with the body length while for Acrida chinensis that increased following a decreasing. But Me-Hg in both increased with body length. Mercury contents in tissues of arthropods are significantly different. The order is abdomen > thorax > head. Mercury and methyl mercury contents in arthropods would lead wild birds, fowls and amphibians in the ecologic risk condition. %K arthropod %K mercury %K methyl mercury (Me-Hg) %K food chain %K Huludao
