Dispersed in the environment, ammonia and hydrogen sulphide are found in various factors (water, air, soil) from where they are taken up by animal and vegetable bodies. Air pollution from these substances mainly results from the decomposition of plant and animal debris. The quality and the composition of the manure, the way they are stored and handled are the main factors that determine the levels of emissions, while the pollutants and odor are being directly emitted by the housing system. This study has observed the determination of ammonia and hydrogen sulfide in a pig farm in Cluj County, and it was carried out during May-September 2011 and 2012. In order to determine the monitored atmospheric pollutants, analytical methods derived from STAS 10812-1976 - Air purity were used. Determination of ammonia from STAS 10814-1976 - Air purity. Determination of hydrogen sulfide. There were no values above the method detection limit (0.3 mg / mc for ammonia and 0.015 mg / mc for hydrogen sulfide) in the sampled and analyzed imissions, and these values were well below the maximum admissible concentration provided by STAS 12574-87 regarding air in protected areas. However, in Europe, a new environmental protection legislation imposes reductions in ammonia and hydrogen sulfide emissions from livestock production.
Key words: ammonia, hydrogen sulfide, pigs, dispersions
