To understand the S content and pollution level of cropland environment and vegetables around a coal-fired power plant,and provide a theoretical basis for evaluation of regional agro-ecological environment quality and food safety,and formulation of limit standard in food.The contents of S in air,soil and vegetables around a coal-fired power plant were determined,with their correlations analyzed.The results showed that the atmospheric SO₂concentrations a 0.5 km （0.66 mg/m³） and 1 km （0.57 mg/m³） around the coal-fired power plant exceeded the second-level limits of the national ambient air quality standard （GB 3095-2012）.The soil sulfur content at 0.5 km （540.91 mg/kg） exceeded the China’s general range and background value of Guizhou Province.The sulfur content in vegetables ranged from 4.5 to 34.3 mg/g,with an average content of 15.2 mg/g.The single factor pollution index of 11 vegetable species was higher than 1.It was found that the decreases of sulfur concentration in air and three vegetables （Brassica pekinensis,Pisum sativum and Lactuca sativa var.angustanalrish） is associated with the increase of the distance.There was a significant positive correlation with the air and soil sulfur content,but sulfur contents in the leaves did not correlated with those in air and soils.It is concluded that the air and soil in certain surrounding areas subjected to sulfur pollution caused by the production activities of a coal-fired power plant,and there is serious sulfur pollution in vegetables around a coalfired power plant.Corresponding measures should be taken to ensure the safety of regional ecological environment.
