Community Structure of Mites in PAH-contaminated Field Soils in Eastern China
摘要
Abstract
Soil mites are good indicators for soil quality assessment, but they rarely have been used to indicate pollution levels of soil polycyclic aromatic hydrocarbons (PAHs). In former studies, mite community structure parameters (usually at group level) such as density, group richness, diversity index and evenness were mainly used as indicators. Since these indicators were established on coarse taxonomic resolution, the assessment effects have usually been found to be variable and unstable. The present study aims at finding more sensitive parameters of soil mite communities to PAHs among individual species, sex ratio and life history traits. Ef-fects of PAH contamination on mite community structure were investigated in vegetable fields in Eastern China December, 2008, by contrasting the effects observed in the polluted soil with the reference study sites. Soil properties and heavy metals were examined as well as the PAH concentrations and mite community structure parameters. Total concentration of PAHs in polluted sites was ca. 18.7 to 26.8 mg kg-1 dw soil, being 5.3 to 7.6 times of that in reference study site. Density and species richness of Macropylina, (Ori-batida), in polluted sites were 3.2 to 8.5 and 1.0 to 2.2 times more than those in reference site, respectively. Oppositely, 1r-species density, male density and sex ratio of Mesostigmata were higher in reference site than in polluted sites by 0.9 to 1.1, 2.2 to 3.3 and 1.0 to 2.6, respectively, and negatively correlated with total PAH concentration. The results suggest that Macropylina and 1r-species, male individuals and sex ratio of Mesostigmata may be sensitive to soil PAH pollution directly or indirectly and can be further de-veloped as indicators for assessment of soil pollution.关键词
