目的探究某电镀厂对周边作物和家禽铬富集的影响。方法 2011—2012年连续2年对北京市怀柔区某电镀厂周边1.5 km范围内的作物及家禽进行取样,对其铬含量采用石墨炉原子吸收法进行测定。结果大部分花生样品检测出的结果都小于报告限(0.025 mg/kg)。玉米样品中铬含量在0.03～0.43 mg/kg之间。白菜和萝卜样品2011—2012年检测结果表明铬含量均明显高于对照组(P<0.01),且铬含量要比花生、玉米高。样品鸡肉中铬含量最高为0.09 mg/kg。结论该电镀厂对其周边种植的花生无显著影响,但会使其周边种植的叶菜类的白菜和根茎类的萝卜富集含量较高的铬,需要引起足够的重视。
Objective To explore the effect of electroplating factory on enrichment of chromium in surrounding crops and poultry. Methods The crops and poultry within 1.5 km around an electroplating factory in Huairou District of Beijing were sampled for two consecutive years from 2011 to 2012. The chromium content was determined by graphite furnace atomic absorption spectrometry. Results Most peanut samples detected less than the reported limit of 0.025 mg / kg. The chromium content in maize samples ranged from 0.03 to 0.43 mg / kg. The test results of cabbage and radish samples from 2011 to 2012 showed that the content of chromium was significantly higher than that of the control group (P <0.01), and the chromium content was higher than peanut and corn. The highest content of chromium in chicken samples was 0.09 mg / kg. Conclusion The electroplating plant had no significant effect on the peanut planted around it, but it would enrich the chromium content of the cabbage and rhizome radish cultivated in the periphery of the electroplating plant, which needs sufficient attention.
