Abstract:
[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.
