摘要
Abstract
Analyzing the heavy metal pollution of wheat around a smelter in Handan can provide reference for planting crops with scientific methods.This research was conducted to determine the concentrations of heavy metal in wheat,five wheat samples were collected from farmland at different distances from the smelter in Handan.Then,the contamination levels were analyzed and evaluated by using single pollution index method and Nemerow comparative index method.The results showed that contents of Cd and Pb exceeded the standards,while Cu did not exceed the standards.According to the single pollution index,within 400 meters from the smelter,wheat had heavy Pb contamination,moderate and light Cd contamination.From the smelter between 400 and 1 600 meters,wheat was not polluted by Cd,from the smelter between 800 and 1 600 meters,wheat had moderate Pb contamination.According to the Nemerow comprehensive pollution index,the index between 1.5 and 4.5,within 400 meters from smelter,wheat was heavily polluted,from the smelter between 400 and 1 600 meters,wheat was slightly polluted.There were obvious correlations between pollution level of heavy metal in wheat and distance from the smelter,the pollution index decreases as the distance increases.The wheat in the farm around the smelter is polluted by different degrees of heavy metal,wheat was not suitable for planting in the studied area.关键词
