de-icing chemicals and sand can run off into roadsides, contaminate groundwater and pollute surface waters; and road salts can be toxic to sensitive plants and animals. sand applied to icy roads can be ground up by traffic into fine particulates and contribute to air pollution.









































roads are a chief source of noise pollution. in the early 1970s it was recognized that design of roads can be conducted to influence and minimize noise generation. noise barriers can reduce noise pollution near built-up areas. regulations can restrict the use of engine braking.

noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with harmful impact on the activity of human or animal life. the source of outdoor noise worldwide is mainly caused by machines, transport (especially planes) and propagation systems. poor urban planning may give rise to noise pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. some of the main sources of noise in residential areas include loud music, transportation noise, lawn care maintenance, nearby construction, explosions, or young people yelling (sports games). noise pollution associated with household electricity generators is an emerging environmental degradation in many developing nations. the average noise level of 97.60 db obtained exceeded the who value of 50 db allowed for residential areas. research suggests that noise pollution is the highest in low-income and racial minority neighborhoods. documented problems associated with urban environment noise go back as far as ancient rome.
