| Abstract: | Presented are the results from experimental investigations into the influence of large tributaries (the Zeya, Bureya and Sungari rivers) on the water quality formation in the Amur river during the transformation of organic matter in bottom sediments. A spectral method and biochemical indication were used to show that toxic heavy metals (mercury, lead, and cadmium) accumulate in river sections of sedimentation of suspended load forming along the right bank from the mouth of the Sungari river to the city of Komsomolsk-on-Amur, and to substantiate the risk of emergence of hydrogen sulfide zones on the lower Amur. |
