对位于美国中部佛罗里达的公路桥梁径流水中的污染物进行了定性和定量分析。这些污染物经排水渠直接排放到邻近的水体和洪泛区，或滞留在池塘，然后再排放到湖泊和溪流。径流中含有铅、锌、铜、铬、铁、镍、镉等重金属，这些重金属在邻近土壤和生物区系中富集，土壤系统对公路桥梁径流中的重金属具有较好的去除效果。建议将桥梁排水引向蓄水池/滞洪池或洪泛区，并应尽可能避免直接将桥梁排水至其下方的水体中。本文总结了中佛罗里达大学为美国佛罗里达交通部和联邦公路管理局进行的几项研究。
Pollutants associated with runoff water from highway bridges located in Central Florida, USA, were characterized and quantified. These pollutants are directly discharged through scupper drains to adjacent water bodies and floodplains or detained in ponds before being released to lakes and streams. Runoff water contains heavy metals such as lead, zinc, copper, chromium, iron, nickel and cadmium which concentrate in adjacent soils and biota.It appears that soil systems are efficient in removing heavy metals from highway bridge runoff. It is suggested that bridge drainage be directed towards retention/detention ponds or floodplains and direct drainage of bridges in water bodies beneath them should be avoided as much as possible. This paper summarizes several studies conducted by the University of Central Florida for the Florida Department of Transportation and the Federal Highway Administration, U.S.A.
