【摘要】 有机污染特征研究可为采取有效的地下水污染防治措施提供科学依据,对饮水安全、可持续发展、生态平衡具有重要意义。选取北方某城市运河下段,根据实测数据,评价了河段周边地下水PAHs类有机物的污染程度,分析了有机污染特征及成因。结果表明:地下水中16项PAHs测试指标全部检出,但大多为微量检出,仅个别指标在个别井中超标,污染程度总体为轻度污染。典型河段地下水有机污染具有丰富度高、主要污染物少、污染程度低、毒性不强及浅层井水质污染重于深层井的特征。更多还原

【Abstract】 Study for pollution characteristics of organics can provide science base for effective measures to prevent and control groundwater pollution. It is of great significance on the safety of drinking water, sustainable development and ecological balance. Based on measured data of groundwater, detection and exceeded standard of the PAHs and pollution level of partial pollutant in groundwater are evaluated, characteristics and causes are analyzed by selecting the lower part of the canal in a northern city. All the 16 PAHs have been detected, but most of them are trace and only exceptional organic exceed standard in the exceptional well, and the overall pollution level is up to light level, with the characteristics of high abundance, few major pollutants, low pollution level. The groundwater quality of the shallow well are worse than those of the deep well in the lower part of the canal in a northern city.更多还原
