消费产品和货物释放的污染物已经成为当今西方国家占支配地位的污染源。高速公路径流是水中沉积物、金属和碳氢化合物的主要来源,并且来自英国的研究数据表明,估计水中污染物总量的10%～12%来自高速公路径流。每条轿车轮胎在磨坏之前平均行驶40 000km,在其使用期间约30%的胎面胶被磨耗掉进入环境中。胎面胶含有范围广泛的各种化合物,并且一些化合物能溶入水中,对水中生物产生毒性。最初研究对 Pollutants released from consumer products and goods have become the source of pollution in Western countries today. Freeway runoff is a major source of sediment, metals and hydrocarbons in water and data from the UK indicate that 10% to 12% of the total estimated pollutant in the water comes from freeway runoff. Each car tire runs an average of 40,000km before it is worn out, and about 30% of the tread rubber is worn away into the environment during its use. Tread rubber contains a wide range of compounds, and some compounds can dissolve in water, toxic to aquatic organisms. Initial research on
