Researchers who work in science and engineering R&D laboratories are commonly exposed to a wide range of chemical, biological and physical hazards. They also may adopt ergonomically poor postures for long periods of time. These factors may increase the risk of adverse health outcomes in laboratory workers. Recently, there were several fatal accidents in the laboratories in universities and research institutes in Korea. Consequently, the ‘Laboratory Safety Act’ was enacted in 2006. However, there are concerns about the health risk associated with chronic exposures to hazards, as the management measures provided in this Act are very limited, focusing primarily on accident prevention and compensation for lab work-related accidents. In this article, the methods for assessing exposure to chemicals in laboratory environments are discussed. Also, epidemiological studies examining the association between laboratory exposure and health effects, including cancer and reproductive toxicity are extensively reviewed. Finally, the possible roles of environmental health professionals in this area are suggested, along with a list of critical research needs for properly assessing laboratory workers’ exposure and risk.
