In the Amur near Khabarovsk, the concentration of harmful substances is significantly increased
The maximum permissible concentration (MPC) of lead in the Amur near Khabarovsk was exceeded 17 times, aluminum 36 times. The Ministry of Natural Resources of the Khabarovsk Territory published the results of the monitoring.
According to the press service of the Ministry of Natural Resources of the Khabarovsk Territory, in addition to exceeding the maximum permissible concentration for lead and aluminum, the permissible values were also exceeded for compounds of total iron - 16,6 times, molybdenum - up to 3,2 times, manganese - up to 8,3 times ...
The analyzes showed that the MPC in water was exceeded for ammonium nitrogen - up to 1,8 times, for nitrite nitrogen - up to 1,9 times, as well as for chemical oxygen consumption.
One of the reasons for exceeding the permissible concentrations in water was the flood - the river floods to locations that cannot be reached at a normal level of water and washes away human waste from the banks - industrial and agricultural. However, as noted in the Ministry of Natural Resources of the Khabarovsk Territory, the excess of the MPC of harmful substances is caused by the negative influence of humans. So the increased content of nitrogen compounds is associated with the discharge of untreated wastewater into the Amur channel.
The monitoring also revealed the excess of the maximum permissible concentration of pollutants in the air. In Khabarovsk - for suspended solids up to 1,3 times, for formaldehyde up to 2,3 times, for sulfur dioxide up to 1,1 times, in Komsomolsk-on-Amur for suspended solids up to 2,9 times, for formaldehyde up to 2,6 times times.
