Atmospheric deposition is an important source of heavy metal in soil and the use dust collection cylinders a traditional monitoring method. This method has limitations agricultural areas because polluted particles may become resuspended eventually deposited into these cylinders, leading to overestimates amount atmospheric soil. To address this concern, we propose that frequent snowfall can help suppress local resuspension fresh snow serve as efficient surrogate surface when collecting samples. investigate rationality method, 52 samples were collected from sites surrounding smelting plants Anyang, industrial region North China. The results revealed concentration cadmium melted ranged between 0.03 41.09 μg/L, with mean values three times higher around (5.31 μg/L) than background farmlands (1.54 μg/L). In addition, factories was north south prevailing winds blowing southwest. Moreover, high concentrations sulfate be categorized different groups via clustering conforming spatial distribution particulate matter emissions sulfur dioxide satellite column concentrations. Finally, positive correlation found content production capacity (R2 = 0.90, p < 0.05) total permitted 0.69, > nearby factories. These findings demonstrate reliable medium for documenting dry associated specific emissions.
