FIELD: chemistry. ^ SUBSTANCE: several large sources of pollutants of river water are selected on the map of a city or some other populated place. Monitoring sites are marked before, in the middle and after each source. The first monitoring site is installed beyond the boundary of the city or some other populated place and the last monitoring site is beyond the boundary of that city or some other populated place. From the first monitoring site, growing distance to the next monitoring sites lying on the boundary on large sources of pollutants along the river bank is measured, as well as before and after the city or some other populated place, and after analysing the river water samples for concentration of pollutants and evaluation of conformity of the measurement results with the maximum allowable concentration, measurement results are evaluated along the river bank depending on the growing distance from the first monitoring site to the next monitoring site and taking river water samples. ^ EFFECT: broader functionalities of measuring pollution of large rivers with waste water and higher accuracy of associating these measurement results to river bank area. ^ 8 cl, 7 dwg |
