In order to improve the analytical quality of the background values in soils and crops, an intercomparison test among 23 laboratories has been organized. Precision and accuracy from results of this test showed that it pays for the effort in laboratories in the determination of Cu, Zn, Cd, Pb and Ni in soils. Content of the above elements in six soil samples was determined. It is suggested that analytical quality control technique should be used in soil background survey.

为了提高农业土壤、作物背景调查分析的质量,农业部环境监测研究所分别组织了土壤参考样品的比较测试。本工作是1980—1981年间对23个背景值调查参加单位的铜、锌、铅、镉和镍测定的准确度和精密度作了观察,估计了参考土壤的含量。结果表明准确度问题更应引起注意。建议在土壤背景值调查中试用分析质量控制。

Four heavy metals--copper, zinc, lead and cadmium were found in the dischargedwater from the lead and zinc smeltry. These four heavy metals remain a rather highcontent in the water all the year around. Most of them was deposited in the silt of theriverbed, it is considered to be the potential harmfulness to fish. These heavy metals gradually accumulate in planktons and then transfer to the fish body. The coeffcientof acamulation is Zn = 1. 6×10~4, Cu =1. 9×10~3, respectively.

Four heavy metals--copper, zinc, lead and cadmium were found in the dischargedwater from the lead and zinc smeltry. These four heavy metals remain a rather highcontent in the water all the year around. Most of them was deposited in the silt of theriverbed, it is considered to be the potential harmfulness to fish. These heavy metals gradually accumulate in planktons and then transfer to the fish body. The coeffcientof acamulation is Zn = 1. 6×10~4, Cu =1. 9×10~3, respectively. The content of lead andcadmium in the fish body is not less than 10~4.The ratio of the content of the four heavy metals in the body of the deformedfish is Zn: Cu: Pb: Cd = 59: 10: 3: 1. The content of cadmium in the deformed fish waseighteen times higher than that in the controlled group. This shows that the highconcentration of cadmium may be the causal factor of the deformation of fish.The experiment has proved that the pernicious heavy metals in the waste waterdischarged from the smeltery have toxic effects on fish. When the water contains1.4% in volume, the TLM of the experimental fish is 48. When the content of zincis high above 1 .5mg/l, fish will die in acute poisoning and the content of zinc andcadmium reach to 0. 25mg/l and 0. 0125mg/l, respectively, the symptoms of ataxia inswimming, paralysis and deformation will appear. Zinc has a quick toxic effect,always cause high mortality. Cadmium has a great effect on deformation. The mixedsolution of Zn and Cd has a combined effect on fish.

本文报道了铅锌冶炼厂废水中所含有的铜、锌、铅、镉污染物对鱼类的毒性调查。初步查明了污染物在不同季节、气温条件下引起鱼类死亡、畸变的影响。通过调查分析发现,污染区鱼体重金属含量显著高于对照区;畸变鱼高于未畸变鱼。畸变鱼体内四种重金属含量的顺序是锌>铜>铅>镉,与水中含量顺序一致。畸变鱼体内镉的含量比对照区高18倍,从而认为镉与畸变可能有密切关系。鱼体的不同部位四种重金属含量有明显差异,值得进一步探讨。

The contents of Cu, Zn, Pb, Cr, Ni, Cd, AS and Hg in the soils above high tide-line along the sea coast from Ganyu to Qidong including ten counties and cities were analysed. Through statistical analysis of these data we were informed that the soils within sampling sites were not polluted, and that the native background-values of these elements were offered. The native background-values (ppm)of Pb was 2.14~20.66; and those (ppm)of other elements in terms of normal distribution were: Cu6.30~23.74, Zn24.37~69.93,...

本研究测定了江苏省赣榆至启东沿海10个县、市平均高潮线以上海涂土壤中铜、锌、铅、铬、镍、镉、砷和汞8种环境元素的含量。通过统计分析说明,采样区内未发现污染,从而获得了各元素的自然背景值。铅的自然背景值为2.14~20.66ppm;其他元素经正态化后的自然背景值分别如下:铜为6.30~23.74ppm,锌为24.37~69.93ppm,铬为42.17~78.05ppm,镍为14.29~25.49ppm,镉为0.028~0.056ppm,砷为5.90~8.86ppm,汞为0.011~0.035ppm。
