Короткий опис(реферат):
There are presented original materials of the study of damageability of leaves plates of 40 wood and bush plants species by mixes of fluoric hydrogen, sulphurous anhydride, steams of sulfuric acid, and ammonia. It has been established that different plants species unequally react to pollution that allowed identifying tolerant (damaged less than 20% of the leaves), middle tolerant (damaged from 20 to 50% of the area of sheet leaves) and unstable (damaged more than 50% of the surface of leaves) plants species. Also the group of species has been marked out with variable stability whose damageability substantially depends on composition of pollution and pollutants combinations
