摘要: <正>公路路面结构是影响路面径流污染的重要因素之一。为探讨公路沥青路面径流污染物的特性。对沪宁高速南京段沥青路面径流排水进行连续取样监测,采用单因子指数法进行评价。结果表明,高速公路沥青路面径流污物SS、COD、BOD;及重金属Cr、Ni、Pb、Cd都具有很强的污染性,且生物可降解性很差。

Abstract: The changes of activities of peroxidase and peroxidase isoenzymes in stem cuttings of Sinojackia xylocarpa during rooting were investigated using colorimetry and polyacrylamide slab gel electrophoresis, respectively. The results showed that changes of the activities of POD increased twice during the different rooting stages. The amounts and the intensities of the isoenzymes bands were also changed regularly with the progress of rooting. Among them, bands of Rf 0. 22 and 0. 31 were charactive.
