Comparison of recommended exposure limits for hydrogen sulphide

In 2006 DECOS assessed the consequences of occupational exposure to hydrogen sulphide and recommended a health-based occupational exposure limit for hydrogen sulphide of 2.3 mg/m3 (1.6 ppm). This Health Council advisory report then served as the basis for the SCOEL recommendation issued early 2007. Although the SCOEL derived its health-based occupational exposure limit from the same critical study and the same health effect (nasal tissue damage), the SCOEL recommended a higher health-based occupational exposure limit than DECOS.
