Approbation of method for evaluation the sediments contamination by heavy metals and petroleum hydrocarbons using regional background standards
Keywords:
sediments quality, heavy metals, petroleum hydrocarbons, pollution coefficient, pollution degree, lakes, Republic of TatarstanAbstract
Approbation of the methodology for calculating the indicators of pollution of bottom sediments by oil products and heavy melals using regional standards for their background content. The values of pollution coefficients and the sediments contamination degree are calculated. To compare the qualitative state of various water objects it is proposed to additionally calculate the specific coefficient of pollution of the Ksp, normalized to the total amount of pollutants.
