目的了解哈尔滨市区主要交通干道土壤中铂、钯、铑的污染状况。方法于2013年9月,采集哈尔滨4个市区(南岗区、香坊区、道里区和道外区)主要交通干道以及对照区(松北区)土壤样品进行铂、钯、铑含量的检测。结果哈尔滨市区交通量大的主要交通道路土壤样品中铂、钯、铑的含量高于交通量小的主要交通道路土壤样品,差异均有统计学意义(P<0.05)。与对照区比较,南岗区、香坊区交通量大的主要交通道路土壤样品中铂、钯、铑的含量,道里区交通量大的主要交通道路土壤样品中铂、钯的含量以及道外区交通量大的主要交通道路土壤样品中钯的含量均较高,差异均有统计学意义(P<0.05);而各地区交通量小的主要交通道路土壤中铂、钯、铑的含量均无明显变化。结论铂、钯、铑三种金属在哈尔滨市区干道土壤存在一定的污染,其污染水平与交通量相关。
Objective To understand the pollution status of platinum, palladium and rhodium in the main traffic road in Harbin. Methods In September 2013, samples of soil samples from four main urban areas of Nonggang, Nangang District, Xiangfang District, Daoli District and Daowai District and the control area (Songbei District) were collected for determination of platinum, palladium and rhodium contents. Results The contents of platinum, palladium and rhodium in the main traffic roads with heavy traffic in Harbin were higher than those in the main traffic roads with low traffic volume (P <0.05). Compared with the control area, the content of platinum, palladium and rhodium in the main traffic road soil samples with high traffic volume in Nangang District and Xiangfang District, the contents of platinum and palladium in the main traffic road soil samples with high traffic volume in Daoli District, The content of palladium in the soil of the main traffic road with high volume was higher than that of the soil with the heavy traffic (P <0.05), while there was no obvious content of platinum, palladium and rhodium in the main traffic road with small traffic volume Variety. Conclusion The three metals, platinum, palladium and rhodium, have some pollution in the main roads in Harbin, and the pollution level is related to the traffic volume.
