Assessment of air quality in Dammam slaughter houses, Saudi Arabia
Journal Title: International Journal of Medical Science and Public Health - Year 2016, Vol 5, Issue 2
Abstract
Background: Air pollution, both indoor and outdoor, is often considered as one of the major causes of environmental health problems. Usually, air in slaughterhouses is heavily contaminated by large quantities of dust particles of biolog - ical and nonbiological origin, toxic gases, and odors. However, t he quality of indoor air in slaughterhouses was rarely investigated. Objective : To evaluate the slaughterhouse indoor environment parameters such as particulate, toxic gases, and bioaerosol levels. Materials and Methods : Indoor and outdoor air quality parameters CO, O 3 , CO 2 , VOCs, PM 10 , PM 2.5 , SO 2 , and NO 2 were measured using references calibrated air sampling devices. Microbial air samples were taken using Staplex air sampler. To assess in door air quality in Dammam slaughterhouse, air samples were taken from two different laboratories. Result: All mean levels of CO 2 inside all slaughterhouse laboratories were higher than their Air Quality Guidelines value, which is recommended by the World Health Organization and in Europe. Indeed, the average levels of NO 2 and CO were lower than their AQGs. However, the mean levels of SO 2 and VOCs were significantly exceeding the air quality guidelines. Bioaerosols examination using Staplex air sampler indicated that limited number of bacterial and fungal strains con - taminate slaughterhouse air in the two laboratories. In comparison with laboratory A, the 44.2% reduction in total viable bacterial count, as compared with laboratory B, reflected the better hygienic standards followed in this new laboratory. Colony count remains constant after 5 and 10 min with approximately 25 CFU/m 3 near director’s offices due to limited working activities. Conclusion : Location of slaughterhouse close to second industrial city of Dammam was significantly having serious impact up on indoor and outdoor air quality data. Indeed, slaughterhouses environment should be controlled for bioaerosol production and bacterial contaminations through good and efficient ventilation system.
