| 1 | Effects of heavy metal pollution of highway origin on soil nematode guilds in North Shenyang, China显示文摘Soil samples were collected with distance at 5,20,40,80,160,and 320 m from the Shen-Ha(Shenyang-Harbin) Highway,Northeast China,to investigate the effect of heavy metals of highway origin on soil nematode guilds.The contents of soil Pb,Cu,Zn,and the nematode community structure were analyzed.The results showed that the contents of total and available Pb,Cu,Zn varied significantly with the different distances from the highway.Pb was the main pollutant in the soils in the vicinity of Shen-Ha Highway.The zone from 20 to 40 m away from the highway was the most polluted area.The highest abundance of soil nematodes was found at 5 m while the lowest at 20 m away from the highway.Thirty six genera of nematodes belonging to 23 families were identified.Nematode guilds having different responses to soil heavy metals were classified into four types.Soil nematode guilds may act as a prominent indicator to heavy metal pollution of highway origin. | HAN Dechang ZHANG Xiaoke TOMAR Vijay Vikram Singh LI Qi WEN Dazhong LIANG Wenju | 2009 | Journal of Environmental Sciences2009，21，2： | 10 |
