moreThe amount of mercury in the wastewater of three dental clinics from United Arab Emirates over a period of 3 to 17 days was quantified using cold vapour-atomic absorption spectrometry technique. The total Hg concentration in the wastewater of these clinics ranged from 25 to 146 μg d-1. The Hg concentration in the wastewater samples collected from the outlets of the dental
chairs after dental treatments varies depending on the type of dental treatment: the average Hg concentration in the samples of only amalgam restoration is 39 μg per sample (std. dev. 37, range 4-142); for samples with amalgam restoration plus other types of dental treatment is 24 μg per sample (std. dev. 24, range <MDL-77); and for sample with no amalgam restoration is 18 μg per sample (std. dev. 16, range <MDL-33).
