Optimal index formula of pollution harm for atmospheric quality assessment based on genetic algorithm.

Based on the concept of rate of pollution harm, an index calculative formula of pollution harm for the assessment of atmospheric environment quality and a new factors weighting mothod were proposed. It was indicated that the parameters in the formula were universal parameters independent of the numbers and kinds of pollutants, as the relative values of pollutants concentration were used instead of the monitoring values. The index formula of pollution harm for atmospheric quality assessment suitable to multi-pollutant was derived by using genetic algorithm to optimize the parameters in the formula. The results of case assessment using this formula were compared with the results using many other assessment methods, showing that application of this formula in the assessment of atmospheric environment quality possesses clear physical meaning, strong generality, simple calculation and convenient use.
