Abstract:
Environmental odour not only serves as a warning of potential health risks, but the odour sensation themselves can also cause health symptoms , such as headaches, nausea, sore throat, cough, chest tightness, nasal congestion, shortness of breath, stress, drowsiness, asthma, chronic bronchitis, and alterations in mood. Swine odour consists of a mixture of volatile organic compounds (VOCs), hydrogen sulphide, ammonia as well as particulates which adsorbed odourous compounds. A plant material-based air purification (PMAP) system was evaluated for odour reduction in this study. The PMAP consisted of a mixture of plant materials which emit volatiles. Measurement was performed in two identical plastic boxes using pig manure, hydrogen sulphide and ammonia gases as odourous source. The PMAP device was placed in only one of the boxes. The results showed that PMAP reduced the intensity of swine odour by at least 50%, the concentration of hydrogen sulphide from 20 ppm to 0.2 ppm for a pure hydr
ogen sulphide source and from 0.4 to 0.02 ppm for a swine manure source. Similarly, the PMAP reduced ammonia concentration from 29 to near 0 ppm for a pure ammonia source and from 38 to 10 ppm for the swine manure source.
