Increasing levels of airborne pollutants deposited either through gravity (i.e. free-falling) or washed out by rain can result in detrimental effects to crops, human health and vulnerable ecosystems by altering critical and delicate chemical balances. Identifying areas most at risk and which would most benefit from measures to control excessive pollutant load is crucial.
