for developing and implementing restoration strategies. We used various
data analyses to identify and quantify sources of arsenic, cadmium,
chromium, copper, mercury, nickel, lead, and zinc in vegetable-growing
soils. A new method of collaborative assessment, combining soil environmental
quality and agricultural product safety, showed that approximately
5.20% of cultivation systems were multi-contaminated by heavy metals.
The nonlinear relationship between pollution sources and the comprehensive
contamination situation was established, deriving from a fitted bivariate
model. The model revealed that anthropogenic sources and natural origins
accounted for 65.8–86.0 and 34.2–14.0% of the comprehensive
pollution, respectively. These results suggested that both human activities
and natural factors contributed to the decline of local soil quality
and the influence of the former was more substantial than that of
the latter.
