[Suspense-dust-, lead- and benzpyrene emissions in the city of Zurich].
Levels of particulate matter, lead and benzo(a)pyrene were measured during 1971--1976 at different monitoring stations in Zurich. Annual averages in city proper ranged between 90 and 180 microgram/m3 for particulate matter, 2 and 3 microgram/m3 for lead and between 6 and 7 ng/m3 for benzo(a)pyrene. Corresponding values for the suburbs as well as for the village of Netstal were about 1/3 to 1/2. Winter levels were higher than the summer ones at all the sites. These differences were more obvious in case of calms. Ambient concentrations of particulate matter and lead measured in the city center were similar to those measured in german cities and were in the same range as air quality standards. Primary attention should be paid to the reduction of emissions, as surveillance of space heating and incineration equipment, and the reduction of lead in fossil fuels.
