铁路危险品货运站环境质量调查

目的]了解上海铁路局危险品货运站环境空气、土壤、地表水质量状况.方法]选择上海南翔站(桃浦站)、无锡站(南门货场)为研究对象,通过对危险品货运站环境空气、土壤、地表水开展现场监测采样,结合实验室分析结果,开展分析评价. 结果]南翔站(桃浦站)环境空气PM10不符合《环境空气质量标准》(GB 3059-1996)二级标准,土壤监测指标中的铅、砷、汞不符合《土壤环境质量标准》(GB 15618-1995)三级标准；无锡站(南门货场)地表水监测指标中的石油类、总磷不符合《地表水环境质量标准》( GB 3838-2002)Ⅳ类标准. 结论]铁路危险品货运站的环境存在一定程度的污染,应加强监测,采取合理治理措施.

A Survey on Environmental Quality of Railway Dangerous Goods Stations

Objective ] To investigate the quality of air, soil, and surface water at dangerous goods stations of Shanghai Railway Bureau. Methods ] Shanghai Nanxiang station （Taopu station） and Wuxi station （Nanmen freight yard） were selected as study sites. On-site monitoring and sampling of air, soil, and surface water were carried out for laboratory analysis and quality assessment. Results ] At Nanxiang station （Taopu station）, the ambient air PM10 concentration was beyond the Level 2 limit as prescribed in Ambient Air Quality Standard （GB 3059-1996）; the concentrations of lead, arsenic, and mercury exceeded the Level 3 limit in Environmental Quality Standard for Soils （GB 15618-1995）. At Wuxi station （Nanmen freight yard）, the monitoring index of petroleum and total phosphorus did not meet the Class IV standard provided in Environmental Quality Standard for Surface Water （GB 3838-2002）. Conclusion ] The railway dangerous goods stations investigated are threatened by some environmental pollution to various extents. Therefore, strengthened monitoring and proper control measures should be adopted.
