So,
Concerns about aerosols derive from a number of other considerations. These include visibility, toxic effects and human health, interactions of aerosols with chemical processes in the troposphere and stratosphere, acid deposition, and air pollution. Of these concerns, those associated with toxic effects and visibility have led the industrialised countries to promulgate standards to reduce the concentrations of aerosols in urban and also more pristine locations.
We were able to learn a lot while the investigation of the aerosol. Aerosol concentrations and forcing will change in the future, both as a result of changing emissions and as a result of changing climate. The uncertainties associated with our knowledge of the present day distribution of aerosols will carry over into uncertainties in analysis of future scenarios. Aerosols that originate from natural emissions may also be expected to change in future scenarios.
