Advance in Environmental Risk Assessment of High Level Biosafety Laboratory

Environmental risk assessment of high level biosafety laboratory is one of important parts of biosafety research, which focused on the environmental effects of pathogenic microorganism leaked from laboratory, including pollution of waste air, sewage and solids. Environmental risk assessment was firstly studied in 1970s in the developed countries, especially in the United States. Ecological assessment and human health assessment have been widely researched, while the laboratory environmental risk assessment of pathogenic microorganism leakage was still not well studied. Pathogenic microorganism can be reproduced on the host body and different types of them have different life cycles in the environment. Therefore, the risks and their changes of pathogenic microorganism are complex in the environment, leading to no guidelines for microorganism risk assessment. (C) 2011 Published by Elsevier B.V.
