M.2013-07-30T19:57:30Z2013-07-30T19:57:30Z20001464-0325http://www.repositorio.ufba.br/ri/handle/ri/12362p. 325-328A system, based on annular gold-coated denuders, was optimized and used in the atmospheric sampling of mercury in urban and rural sites of the Alta Floresta, a region in the Brazilian Amazon. Results showed that vapour phase mercury (Hgv) is dominant in samples collected in both sites. However, particulate mercury (Hg) may sometimes be signi®cant at the urban site, with values representing up to 77% of the total Hg collected during sampling, but may also be insigni®cant at the same site, depending on the gold commercialization activity and, probably, on the meteorological conditions during the sampling period. The presence of mercury in both the vapour and particulate phases in the atmosphere of the urban site can explain the high mercury concentrations found in urban dust reported for some cities in the Amazon, and also the relatively high Hg concentrations found in soils adjacent to the urban centre of Alta Floresta. It appears that the urban dust of ``garimpo'' areas in the Amazon can act as an ef®cient adsorber of Hgv emitted by gold dealer operations during the puri®cation process. Mercury emissions from gold dealer shops in the Amazon have been considered as a human health risk through the inhalation of Hg vapour. However, although true for indoor sites, the signi®cant contribution of particulate phase Hg shown in this study in outdoor urban sites calls for a reevaluation of the risk assessment estimates performed up to now in urban centres in the Amazon.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-07-30T19:57:30Z No. of bitstreams: 1 999999999999999999999.pdf: 102653 bytes, checksum: c5ae79778f0e92cdb35cb4c028ce22fd (MD5)Made available in DSpace on 2013-07-30T19:57:30Z (GMT).
