Abstract
There is a considerably increasing concern about the speciation of antimony because anthropogenic emission has resulted in an increasing concentration of antimony in the environment. Apart from inorganic Sb species, methylate d Sb species have been detected in a variety of environmental samples. Howe ver, little is known about the distribution of Sb species in airborne parti culate matter (APM). The speciation of Sb species in APM was performed usin g both anion-exchange and size-exclusion HPLC-ICP-MS detection. A Japanese quality control sample for APM (AS-1, 92 mu g g(-1) Sb) and an APM sample c ollected in Tokyo (APM sample, 56 mu g g(-1) Sb) were investigated. In aque ous extracts of APM sample and AS-1, apart from the major Sb(v) species (ca . 80%), trimethylantimony species (TMSb) and several hydride active unknown Sb species were for the first time detected.
