A Mini Review on Thermally Polluted Water

Henglong Xu

The impact of thermal pollution of leachate from a post-coal mine mound on three macrophyte species Phragmites australis, Typha latifolia, and Scirpus sylvaticus was examined over the entire foliage season. Hydrological measures showed that the temperature of the leachate was 50ºC at the point of leachate flux and dropped to 15ºC at the end of discharge conduit. The periodic temperature and conductivity of leachate from the two control spots, a weakened water sluice in the vicinity of the waste tip and a contaminated sluice, differ significantly. Still, only the temperature explained the differences in factory traits. In April, and in some cases in May, shops in the leachate were significantly advanced than in those on the control spots in terms of biomass and factory height. Thermal pollution caused a phenological shift in all species and also caused Scirpus shops to die out more snappily. Temperature also affected the proportion unfolding. Vegetative individualities none of Scirpus shops started to bloom.
