Concentrations of total recoverable inorganic tin (TRISn), monomethyltin (cas 16408-15-4) (MeSn3+), dimethyltin (Me2Sn2+), trimethyltin (Me3Sn+) and (3-dimethylsulphonio)propionate (DMSP) were determined in leaves of Spartina alterniflora from three sites in the Great Bay estuary (NH) from 8 May to 15 September 1989. Total methyltin concentration increased from 8·9 ng g−1 (fresh weight) on 8 May to 472 ng g−1 on 23 May, decreased to 52 ng g−1 on 7 June and 16ng g−1 on 20 June, and remained low until the last sample on 18 September. Statistical calculations showed that methyltin concentrations varied significantly with sampling week, but not with site. DMSP concentrations showed very different behaviour. During the same sampling period DMSP concentrations varied only from 7·5 to 26 μmol g−1 (fresh weight). DMSP concentrations varied significantly for site, but not sampling week.
