    No full text
    An extensive ambient air pollution monitoring network was designed as part of the Vaal Triangle Air Pollution Health Study (VAPS). The objective of the outdoor study is to determine air quality levels in the Vaal Triangle region. The monitoring was designed simultaneously with the health component of the VAPS. The network HUS designed according to specific criteria and has been in operation since July 1991. Six monitoring sites, which are presently in operation, were gradually phased in over the last 12 months. The pollutants which are considered as important and which are monitored in the area on a continuous basis for 365 days a year are: sulphur dioxide, nitrogen oxides, ozone, non-methane hydrocarbons particulates and hydrogen sulphide. Meteorological parameters are also monitored. The design of the network, as well as preliminary results from two monitoring sites, will be discussed
