ABSTRACT

 

Saudi Geological Survey Agency conducted this study   under the supervision of the Saudi Gulf Company.  This report represents the main findingsof our work with regards to the environmental impact of the National Rock Wool Factory on the surrounding area and workers health.  Indoor and outdoor samples were collected using Staplex Hi-Vol air samplers (PM10). Personal samples were taken by personal air samplers fixed on the workers`chests during their 8-hour shifts. Air conditioner filter dust samples and dust samples were collected and analyzed for metal contents.  Carbon monoxide and sulfur dioxide concentrations were measured using an Oldham portable gas detector (The MX 21 Plus).  Raw materials and solids as well as liquid wastes were chemically analyzed in the laboratory, Manufacturing operational and handling methods for the raw materials and products were reviewed and evaluated.  The study showed mild impact from the factory on the surrounding area; however, the greater impact was indoors. Poor management combined with bad ventilation and a lack of environmental awareness resulted in exposures to high levels of air pollutants such as carbon monoxide, sulfur dioxide and particulate matter.  An initial health survey was carried out and the results showed some health impacts on workers. The preferred practical control and disposal methods for various pollutants were identified.
