Objective This study aims to clarify the situation of cadmium pollution in the agricultural soil of Shijiazhuang City from 2016-2022,evaluate potential health risks to the population,and assess the effectiveness of"the three-year initiative"in reducing cadmium pollution.Methods In six selected project counties,20 soil samples were collected annually from each county.Samples were collected from monitoring points in each county annually between July-August.Cadmium levels in the soil were evaluated using standard limits.Additionally,the study used the geo-accumulation index method,and potential ecological risk index method to assess the situation.Results A total of 840 soil samples were collected.In 2016 and 2017,cadmium levels were relatively high,primarily concentrated in Zhengding County and Zanhuang County.After"the three-year initiative",there was a decrease in the average cadmium pollution level in Shijiazhuang City.Specifically,and cadmium levels decreased in Zhengding County,Zanhuang County,Luancheng County,Gaocheng County,and Luquan County after implementation.However,Wuji County saw a slight increase in cadmium levels.Conclusions The level of cadmium pollution in agricultural soil in Shijiazhuang City significantly decreased after the implementa-tion of"the three-year initiative".This indicates that"the three-year initiative"had a certain effect in reducing soil cadmium risk.However,there is still a need to strengthen the investigation and monitoring of cadmium pollution in the soil to formulate timely policies to address potential risks.
