Environmental Assessment of the State of Atmospheric Air in Conditions of Different Technologies of Poultry Production

Abstract

Aim of research – the integral environmental assessment of atmospheric air pollution with hydrogen sulfide, nitrogen and sulfur oxides in zones of the intensive poultry farming and egg production.Materials and methods. The research was carried out in zones of location of poultry enterprises of broiler and egg production by variants: 1. SPZ (sanitary-protection zone) – 50 m from poultry yards;2. OD – 1 (observation district) 500 m beyond SPZ;3. OD – 2 (observation district) 1700 m beyond SPZ;4. Control 10 km from poultry enterprises.Poultry enterprises are situated in Kyiv region in identical soil-climate conditions. The analysis of the content of aeropollutants NO2,SO2,,H2S in atmospheric air was realized using the gas analyzer 604-342EH07-02 (“KSM – 05” LTD, 2013).Results of research and their discussion. The results of the quantitative analysis of mean indices of physical-chemical analysis of NO2, SO2, H2S content for 2014–2016 were received. The content of NO2,,H2S in atmospheric testifies to the stable tendency to the exceed of the mean maximum allowable concentration (MACm.d.) and maximal one-time allowable concentration (MAC max), except the control AC. For the integral environmental assessment of the state of air environment in zones of industrial poultry farming was offered the index of atmosphere pollution (IAP) and the complex index of atmosphere air pollution (Ciap). For eggs production ƩIAP may be set in such a way in order to decrease: H2S(7,94)≥NO2(6,69)≥SO2(6,43). In zones of boiler production the other tendency of Ʃ IAP change is observed: SO2(26,62)≥NO2(11,31)≥H2S(6,01).Conclusions. Thus, the important and necessary condition for eco-friendly poultry farming is a system control of the state of atmospheric air and the content of priority and dangerous aeropollutants in zones of powerful poultry enterprises location. The use of IAP and Ciap is most optimal for the integrated environmental assessment of atmospheric air pollution with aerogenic pollutant
