摘      要：Cadmium(Cd)is one of the most toxic heavy metals in the *** deposition has been found to be the main source of Cd pollution of soil on a large scale in China,and identification of the relationships between anthropogenic emission,atmospheric deposition,and Cd accumulation in soil is important for developing ways to mitigate Cd non-point *** this study,the relationship between atmospheric emission,atmospheric deposition,and soil Cd accumulation in the Middle-Lower Yangtze Plain in China was investigated using datasets of atmospheric emission,deposition,and soil accumulation from the literatures published between 2000 and *** results showed that the soil Cd accumulation rate in the study area exceeded the national average(4.0μg kg^(–1)yr^(–1))and continued to accumulate in recent decades,although the average accumulation rate decreased from 9.45μg kg^(–1)yr^(–1)(2000–2010 period)to8.86μg kg^(–1)yr^(–1)(2010–2020 period).The contribution of atmospheric deposition flux to Cd increment in the soil was in the range of 22–29%,with the atmospheric deposition flux decreasing from 0.54 mg m^(–2)yr^(–1)(2000–2010)to 0.48 mg m^(–2)yr^(–1)(2010–2020),both values being greater than the national *** Cd deposition and emission were highly correlated in a provincial administrative region,which is close to a ratio of *** factors may be in a state of dynamic change due to the influences of new Cd emission control technologies and environmental *** the main sources of Cd emissions,dust,and smoke emissions per ton of non-ferrous metal production decreased by 64.7%between the 2000–2010 and 2010–2020 *** new environmental policies have been instigated,atmospheric emission of Cd is still *** was hoped that the findings of this work would provide a scientific basis for the rational control of atmospheric emissions and Cd pollution of soil.
