Assessment of Water Pollution by Bioindication Method

Abstract

The quality of polluted water was assessed using bioindication method based on identification of changes of algae reproduction due to the influence of toxic substances contained in aquatic medium. This makes possible to assess the influence not only by concentration of pollutants, but also by final effect: their toxic action on living organisms. Investigation was carried out on example of water pollution by chlorination by-products and batteries. The results show high reliability of bioindication method for water pollution assessment. Besides, the method of water objects monitoring was improved. This method is based on identification of phytoplankton particles on the basis of comparison of array multispectral images using Bayesian Classifier based on Mahalanobis distance.
