Biomedical waste in healthcare: a comprehensive study on microbial analysis, radioactive analysis and prevalence of opportunistic bacteria

Abstract

Proper biomedical waste (BMW) management is one of the crucial steps in ensuring public health. Covid 19 has given an emergence to maintain proper waste management. Microbial analysis and radioactivity tests are two objectives of this paper. Microbial analysis in BRAC University wet lab and radioactivity tests in Bangladesh Atomic Energy Center (BAEC) has been performed with three tertiary public hospitals' waste disposals including solid and liquid wastes. The waste has been collected from central waste collection bins of different departments including - pathology, urology, surgery, cardiology and hospital ward. The collected waste has been in contact with human beings and affects the human immune system labeled as infectious and hazardous. In this regard, opportunistic bacteria search is also included in this research. The organisms that have been found in waste are - Escherichia coli, Enterococcus faecalis, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus. Some other biochemical tests are in process for the recognition of further characteristics. Hence this research paper has been conducted following normal safe ranges of alpha, beta, gamma ray and microbial population in human contact for radioactive analysis. The research process is carried out with analysis and preparing proper management techniques through bio-statistical analysis using SPSS. It also intends to create awareness among the people involved in the health care unit further.
