[The ecological hygiene assessment of the water environment based on factor analysis]

Regularities of the formation and spread of pollution of water objects in the area of sewage discharges of the cellulose-paper works were revealed. The bottom nature of water pollution and their change in their contribution in relation to the distance were determined. The bottom pollution of water was comparable with that due to sewage and varied from 46 to 69%. The transformation of organic matter makes a significant contribution to the total water pollution.
