There’s been a general ban on use of mercury in Sweden since 2009 but it’s still estimated that the Swedish population have between 40 – 60 tons of amalgam in their teeth. Dental amalgam contains about 50 % mercury and studies have shown that despite the installation of amalgam separators mercury emissions from dental clinics still occur. Environmental officers in Swedish municipalities are important in the work to reduce mercury emissions from dental clinics in Sweden. The purpose of this report was to investigate how Swedish municipalities carry out supervision of mercury management in dental clinics as well as to investigate the legislative demands on the mercury management in dental clinics. The purpose was also to investigate possible similarities and differences between municipalities with varying populations. Environmental officers in Swedish municipalities answered a web survey. The results show that the knowledge about mercury management in dental clinics is greater among environmental officers in larger municipalities compared to smaller municipalities. Some of the smaller municipalities don’t carry out any inspections of dental clinics whereas every larger municipality does. Larger municipalities have higher demands on mercury management in dental clinics than smaller municipalities. The legislations used are broadly the same among the municipalities but because the demands made by the municipalities differ, it indicates that the interpretation of the legislations vary between municipalities in Sweden. Collaborations between different municipalities, more distinct guidelines and guidance are probably necessary to achieve a consensus amongst the municipalities when it comes to mercury management in dental clinics.
