Abstract

The measurement of total antimony and antimony species concentrations in biological tissues, bacterial cultures, sediments and natural waters is
described. An emphasis is on the development of novel procedures to concentrate and measure antimony species. Antimony species can be extracted
from marine animal tissues with dilute nitric acid and tetrafluroboric acid and sediments with nitric and hydrochloric acid using microwave heating.
Antimony species can be extracted form sediments with citric acid and separated and quantified by high performance-liquid chromatography-ICPMS.
Volatile antimony species generated by bacteria cultures can concentrated by solid phase micro extraction and measured by desorption, cryogenic
trapping and gas chromatography-mass spectrometry. Antimony species in natural waters (sea and lake waters) can be converted to their hydride
forms, cryogenically trapped and measured using ICPMS. All methods are sensitive enough to measure antimony concentrations at levels commonly
found in the environment
