| Abstract | Developing industrial animal husbandry is characterized by reduced areas and sizes of premises per unit of live weight of an animal, greater capacity of buildings and individual sections, insufficient gaps between buildings with huge vent emissions and liquid manure effluents. In these conditions not only tasks of animal health but also problems of preventing environmental pollution by industrial animal husbandry wastes became urgent. Research methods. Researches were carried out during 2011 – 2013, in LLC “E & M Beautiful Land” (Cherkasy region, Khrystynivka district, urban village Verkhniachka). To control the chemical composition of air we used versatile portable gas analyzer of UG-2 type. It determined ammonia and hydrogen sulfide concentration in the air of impact zone of livestock premises. Sampling was made respectively to conventional techniques at a height of 1,5 – 3,5 m. Research results. Analyzing results of the research it can be seen that the highest content of ammonia and hydrogen sulfide in the air is at the point of emission. With increasing distance from the point of emission ammonia concentration decreases in the air: 20 m – 2,5 (in summer) and 1,5 times (in winter), 100 m – 27 and 25 times respectively. The annual average actual concentration of ammonia exceeds the maximum allowable concentration in 26 times (the distance from the point of emission – 100 m) and hydrogen sulfide concentration – in 11 times. Conclusions. The results of our researches show that the level of air pollution in the zone of a livestock complex is high on indicators of concentrations of harmful gases – ammonia and hydrogen sulfide. It is dangerous for the health of people living in the area and for the environment in general (acidification, eutrophication and disturbance of the natural balance of ecosystems). | ||
