Objective: A study on indoor air play important roles in human health by polluted indoor labrotory and causes some diseases such as infections skin, eyes, respiratory system , allergy and biotoxicity. Air is made up of enormous of microorganisms mainly bacteria. Their estimation is important as an indication of cleanliness of any particular environment. The presence both bacteria and fungi in indoor air is problem of health protection due to a long time period that workers and students stay indoors. Determination of level microbial pollution indoors is necessary to assess the health hazard for indoor air quality control. This study provides information on microbial contamination level of indoor air of biological labrotary was estimated. Material and Methods: Collected air samples from seven bio-laboratories and low, up corridors locations during April-June 2019. Air samples were taken three months : in the in the afternoon. Results: The higher of percentage of isolated airborne bacteria Staphylococcus aureus and Staphylococcus epidermis, it was 58.57% and 26.84% for all biological laboratories respectively at study location, while the lowest percentage were Klebsiella sp. and Protus sp., it was 11.98% and 4.29% for all biological laboratories, respectively. Conclusion: It is concluded from the current study that is advisable that estimate to check microorganisms loads in Laboratories and prevent their increase and spread

The following studies have shown the results of low, moderate, strong and very strong soil contamination as well as the change of soil morphological characteristics, the strains separation of oil-breaking bacteria and the development of recultivation technology. According to the results, the changes in soil morphological characteristics differ in contamination degree, and the morphological characteristics of very strong soil contamination (more 25 g/kg) have dramatically changed. The oil-breaking bacterial strains such as MFD-100 Pseudomonas stutzeri, MFD-200 Pseudomonas caryophyllis, MFD-5000 Bacillus subtilis are separated from oil-contaminated soils. Based on these strains, the three-stage recultivation technology has been developed, and as a result of the conducted recultivation, the soil cover is purified up to 81.8%. Soil purification rate is divided into the following efficiency indicators: 1 - soil purification rate 0-20%, 2 - soil purification rate 20-40%, 3 - soil purification rate 40-60%, 4 - soil purification rate 60-80% and 5 - soil purification rate 80-100%. After the soil recultivation, the productivity indicators such as nutrient and humus content as well as pH environment are improved.

Clinical waste management in the hospital plays a considerable role in healthcare facilities, as it serves as the frontline that deals with clinical disposal, where zero cross-contamination exposure to the public must be ensured. In this paper, a preliminary study was conducted to investigate the biohazard container etiquette in a selected Malaysian healthcare facility. The yellow bin is a designated container used to dispose of contaminated clinical waste that could spread pathogenic microorganisms to humans. The findings show that several biohazard bins were positioned in non-restricted pathways containing general plastic, papers, and rejected medical parts. It is assumed that a lot of effort is required to educate both the public and the staff regarding biohazard bin etiquette. To date, more inspections are still being conducted to determine the impact of misusing the biohazard bin. Nevertheless, the authors are currently developing descriptive statistics to investigate the public awareness of biohazard bin etiquette in hospitals. A new strategy to improve clinical waste management sustainability in a healthcare facility is also being proposed
