The environment of the harmless vegetable production area must conform to certain environmental quality standards, so the study of the environmental quality is the first step to produce vegetables. In some detected spots, it was found that the content of Hg in soils and the content of Hg and NO-3 in vegetables were higher than the standard values. However the area can still be used to produce harmless vegetables, as long as effective prevention measures are taken.
