| 摘 要： | 测定了江苏省苏州城市不同河流段底泥中各种形态磷的含量。结果表明,河流底泥磷含量总体都较高,总磷的含量大多数在1 000 mg/kg左右,远远超过了当地土壤中总磷含量的本底值。底泥污染主要是无机磷污染,无机磷占到了总磷的72%~91%;有机磷含量较低,占总磷的9%~28%。无机磷可分为非磷灰石无机磷和磷灰石无机磷,二者在不同河道底泥中的含量和比例都不尽相同。

| Abstract: | The content of various forms of phosphorus in different rivers of urban Suzhou in Jiangsu Province was determined.As indicated by the results,the P content in river sediment was generally high,most of them were above 1 000 mg/kg,far beyond the background value of local soil P content.The sediments were mainly polluted by inorganic P,which accounted for 72%-91% of total P;while organic P only took for 9%-28%.Inorganic phosphorus could be divided into non-apatite inorganic phosphorus and apatite phosphorus.Th... |
