Components present at trace (^g l-1) levels can have a major affect on water quality if they can bioaccumulate in organisms or have a high degree of toxicity. These components usually fall into the two categories of organic pollutants and metal ions. Instrumental methods for the determination of the components have been discussed, along with the necessary extraction and pretreatment steps. The predominant instrumental technique for organic components is gas chromatog-raphy, whereas atomic spectrometric techniques are the most frequently used methods for metal ion analysis.
