2010 Shanghai World Expo will tuck up the veil River on both sides of the 5.28 square kilometers of land as the site of the Expo venue. Because the region is the origin of modern heavy industry Jiangnan Shipyard is located， and the region has a large number of heavy industry factories， a large number of metal dust was discharged to the atmosphere. through atmospheric circulation enter the soil， the region has different levels of heavy metal contamination of soil. The Expo will address issues of soil pollution by heavy metals， corresponding repair line with sustainable development proposals Expo to ensure the success and future development. In the course of the study， we will collect soil samples microwave digestion and ICP - AES， and other treatment processes the same was not to the point of heavy metal soil concentrations. And through the soil and environmental quality standards， compared to draw heavy metal pollution : the choice of four heavy metals， Lead and arsenic pollution of the smaller， in line with the health needs of the human body; and cadmium pollution in the absence of the corresponding standard value， It is not possible to make precise positioning， but with the outside of the soil samples， it was found that the concentration of cadmium is generally high， likely to test the process as a result of errors; Nickel and the extent of pollution is a more serious matter. So the focus of the restoration of Nickel on. Our proposal is to have a higher concentration of nickel role of the grass in front of the vehicle to alleviate nickel pollution.
