Methods are described for the determination of bis(tributyltin) oxide (BTBTO)in air at concentrations in the region of the threshold limit value of 0.1mg/m3 for organic tin. The air was sampled through glass fibre filters which were extracted either with methylisobutyl ketone and the BTBTO was determined int he extract by atomic abosption spectroscopy, or the filter was extracted with toluene followed by pyrolysis gas chromatography. The former method is preferable.
