Grain-size partitioning of tributyltin (TBT) and its degradation products di- and monobutyltin (DBT and MBT) in coastal sediments revealed a strong tendency on the part of these compounds to adsorb on to detrital fragments (algal and leaf debris mixed with light mineral particles). Butyltins have been weakly detected in sands washed from these debris, a finding which underlined the need to separate both fractions (sands and debris) for an accurate assessment of the grain size partitioning. In debris-free sediments, butyltins were mostly detected in the silt/clay fraction. It was found necessary to consider the total amount of butyltins in each fraction, and hence the relative proportion of each fraction, in order accurately to assess the grain-size... |
