Abstract
The quality of air and rainwater in Zimbabwe was assessed by analysing the levels of gaseous pollutants in the air and the chemical composition of precipitation samples. The air quality was assessed by monitoring the levels of sulphur dioxide, nitrogen dioxide, hydrogen chloride and ammonia at one urban (University Campus) and two remote sites (Mazowe and Mount Hampden farmlands) around Harare during 1991 and the results were compared with the 1990 data for the same period. Rainwater quality was characterised by analysing precipitation samples from five selected locations in Zimbabwe for the 1990–1991 season. The levels of nitrate, chloride, sulphate, ammonium, potassium, sodium, potassium and calcium ions, in addition to the pH and conductance values were determined. The cation/anion ratios were calculated based on the experimental data for the rainwater samples. The quality status of the atmospheric environment in Zimbabwe is discussed.
