title: Urgent problems of improving background air pollution monitoring systems.
abstract: For more than 12 years, systematic observations of background air pollution have been carried out in accordance with the WMO Programme using the network of USSR stations located in sparsely populated settlements and in a number of neighbouring cities. The parameters involved include spectral radiation measurements, determination of chemical composition of precipitation and the concentrations of a number of atmospheric pollutants. Analysis of the data obtained allows conclusions to be drawn on the capabilities of the current system and to evaluate methods of improving it.In order to further improve the monitoring system, it is recommended that the system should perform the same observations on air pollution and precipitation as carried out by other international and national programs, and also to create centralized laboratories to deal with the analysis of samples from these monitoring stations. Additionally, solid sorbents are emerging as an effective means of sampling certain air pollutants. They may be sent by post, they increase the accuracy of measurements and allow air sampling intervals of up to 7-10 days, thus synchronizing this period with the interval of precipitation sampling.
