Analysis of precipitation,The implementation of a precipitation chemistry measurement programme can be an extremely complicated and expensive task. It is necessary that the measurement programme be well designed so that the resulting data will be useful and the programme cost effective. Mancy and Allen suggest eight key steps in the design of a monitoring system:

Planning and execution of an air pollution study,Pollution monitoring is an expensive business and it should not be undertaken lightly. In a world of limited resources, any monitoring programme will probably have taken priority over some other socially useful exercise. It will therefore be assumed in the following discussion that data are being acquired because:

Because of the variety of sampling schemes which may be used to obtain ‘ambient’ air samples, the objectives to be achieved by the sampling programme and subsequent analysis must be thoroughly and clearly defined before proceeding further.

Aerosol pollutants may be formed within the atmosphere as a result of gas-phase reactions followed by condensation of the products, or by reactions taking place in the existing atmospheric aerosol phase.

More recently, interest in this general field has been concentrated on investigations into the identification and measurement of levels for groups of compounds or even individual pollutants.
