Abstract:

This study is made to see the types and amounts of pathogen microorganisms in the waste water of hospital labarotories and also the removal capacity in thr disinfection neutralization systems of these organisms. In this pilot study, Keçiören Training and Research Hospital was chosen as study field. Pathogen microorganism levels in the monthly inlet and outlet waters in the Medical Waste Neutralization and Disinfection System of the hospital labarotory were checked on 5-month periods. Findings led by the samples were pathogen bacteria (Pseudomonas aeruginosa, E. coli, Acineto baumanii, CNS) and viruses (Anti-HCV, Anti-HIV, HBsAg, HAV-IgM, Toxoplazma-IgM, Rubella-IgM and CMV-IgM). As a resutl of these analyses, no bacteriological or pathogen viruses were detected in outlet waters whereas some were detected in the inlet waters of some samples. Another conclusion is that the package treatment system Works efficiently with regards to pathogen removal. The results of the study are especially important in revealing that there are no standards for pathogen microorganisms in the discharde regulations in our country. The fact that in the waste waters of hospitals where no treatment process is followed can contain seriously pathogenic organisms is another remarkable result with regards to environmental and public health.
