According to the World Health Organization (WHO), air pollution poses a significant threat to health. Despite technical progress in the development of motor vehicle engines, the transport sector has the highest emissions of particulate matter and nitrogen oxides in particular. In addition, more and more people are exposed to harmful environmental pollution. The reason for this is not only the rising volume of traffic, but also the increasingly dense population growth in cities.
The German Federal Immission Control Act stipulates that harmful environmental impacts on areas in need of protection must be avoided when building public roads.
The legal definition of when a harmful environmental impact exists is set out in the Ordinance on Air Quality Standards and Emission Ceilings (39th BImSchV), which is based on European directives. At present, the immission limits for particulate matter (PM10 and PM2.5) and nitrogen dioxide (NO2) set out in the Ordinance are of particular importance. They are based on WHO recommendations and are frequently exceeded in conurbations at traffic-heavy sites.
In the case of new road construction and expansion planning within the framework of planning approval procedures and feasibility studies, we prepare forecasts regarding air pollution levels. In the event that the immission limit values are exceeded, Möhler + Partner Ingenieure AG proposes measures that ensure compliance with these values.
In order to control the actual air quality on existing roads, we carry out measurements for you and assess them on the basis of the legal requirements.
Besides the protection of human health, nature conservation is also important. Air pollutants from traffic and agriculture result in nitrogen depositions such as ammonia and nitrogen oxides, which reduce species/plant diversity in nature reserves. For your road construction or expansion plans, we can map the effects on fauna and flora habitats (FFH) and evaluate them from an immission control perspective.
