摘要:
用等离子发射光谱仪测定了公路两侧苹果中的Pb含量。结果表明,汽车尾气对苹果造成的Pb污染,在公路两侧30 m范围内较高,5 m和30 m处果实果皮中的Pb含量分别为0.292m g/kg和0.291 m g/kg,是无公害苹果生产标准(0.2 m g/kg)的1.46和1.45倍。随着偏离公路距离的增加,苹果中Pb含量逐渐降低。在距离150 m处降至当地的背景值。对苹果套袋能够有效地降低果实中的Pb含量,最高可降低80%左右。
Abstract:
Lead concentration in apple cultivated along the road sides by ICP-AES. The? results demonstrated? apples had been polluted by the lead of vehicle emission. The Pb contents in the apple at 5 m and 30 m along the roadsides were 0.2917 mg/kg,0.291 3 mg/kg,which were 1.46 and 1.45 times higher than the standard of the pollution-free fruit.With the increase of the distance? from the road, the Pb concentration in apple decreased gradually, it would reach the blank level at the distance of 150 m.Bagging? apple fruit could effectively decrease the Pb concentration, by 80% in maximum.
