The emission of noxious gases is a significant problem in pig production, as it can lead to poor production, welfare concerns, and environmental pollution. The noxious gases are the gasses emitted from the pig manure that contribute to air pollution. The increased concentration of various harmful gasses can pose health risks to both animals and humans. The major gases produced in the pig farm include methane, hydrogen sulfide, carbon dioxide, ammonia, sulfur dioxide and volatile fatty acids, which are mainly derived from the fermentation of undigested or poorly digested nutrients. Nowadays research has focused on more holistic approaches to obtain a healthy farm environment that helps animal production. The use of probiotics, prebiotics, dietary enzymes, and medicinal plants in animal diets has been explored as a means of reducing harmful gas emissions. This review paper focuses on the harmful gas emissions from pig farm, the mechanisms of gas production, and strategies for reducing these emissions. Additionally, various methods for reducing gas in pigs, including probiotic interventions; prebiotic interventions, dietary enzymes supplementation, and use of medicinal plants and organic acids are discussed. Overall, this paper provides a comprehensive review of the current state of knowledge on reducing noxious gas in pigs and offers valuable insights for pig producers, nutritionists, and researchers working in this area.

In this study, we conducted an assessment of the risks posed by the noxious chemicals often handled at the analysis centers of organizations involved in Work Environment Measurement (WEM) using the Chemical Hazard Risk Management (CHARM) system. For this purpose, six organizations involved in WEM located in Seoul and Gyeonggi, which conducted the risk assessment, were selected and, as a result, 29 materials were selected as chemical substances presenting a risk of exposure. In terms of their physical properties, there were 16 liquid and 10 solid materials, and for the special management materials (CMR), the findings were as follows: 'Carcinogenic' 1A - 11 and 1B - 1 (2 - 8); 'Mutagenic' 1A - 4 and 1B - 3 (2 - 8); and 'Repro-toxic' 1A - 0 and 1B - 1 (2 - 6). In the risk estimation, 30.4%, 66.1% and 3.6% of the materials presented 'low', 'average' and 'high' risks, respectively. In addition, two of these six institutions had materials presenting a 'high' risk. This study is significant in that the risk assessment was conducted using CHARM, a chemical substance assessment tool. It is expected that the results will be utilized as the basic data for safety assessment, the establishment of a plan for emergency measures and drawing up a safety management manual, and the institutional and legal management of accidents and risks in the analysis centers of organizations involved in WEM and the management of chemicals by drawing attention to the risks involved.
