The conducted genetic and physiological and biochemical analyzes of water and ash from the reservoir and drainage ditches Dobrotvir thermal power station (DTPS). It was established that the content of heavy metals in the studied samples is largely complies with the maximum allowable concentration (MAC), but when compared with similar surveys in 20102011 observed increase is isolated to individual metals. In conducted the physiological analyzes of stimulation observed morphometric parameters of Brassica napus L. seedlings in the aqueous extract of ash concentration of 2550 g/l, and an increase in the content of photosynthetic pigments concentration of 25 g/l. We found that the induction of chromosomal aberrations for the actions of ash DTPS about 35 times and by the action of water from drainage ditches and reservoirs DTPS 24 times compared with the control.
