ABSTRACT
The worsening health conditions of the inhabitants of large cities, and especially the increasing occurrence of allergic diseases and asthma in children, has led to a new approach towards street dust as an aspect of the urban environment, which has a significant impact on the health of city dwellers. We must also take into account the fact that streets form a large percentage of urban areas. We are not able to eliminate street dust; we can only reduce its emission or remove it regularly by cleaning streets. The presence of heavy metals in suspended dust and soils of the urban environment is a well-investigated subject both in Poland and all over the world. The problem of street dust (loose material deposited on streets and squares in cities) is very poorly investigated in the world, and almost hardly at all in Poland. Street dust is common in cities.The composition of street dust may include soil erosion from land, industrial emissions, construction and automotive exhausts, debris from the surface of streets and car tires. Research scientists from Norway have shown that street dust and suspended matter PM10 depend on each other.
