摘要：
The occurrence of volatile organometallicspecies of tin was evidenced and investigatedin three major European estuaries, such as theGironde (F), the Rhine (NL) and the Scheldt(B/NL), along with the salinity gradient andfor all seasons. The most ubiquitous species,observed in surface water, were found to bemethylated forms of butyl-tin derivatives(BunSnMe4-n, n = 0–3), withconcentrations significantly higher in theScheldt (ca. 75–2000 fmol l−1) than in theRhine (ca. 5–125 fmol l−1) and the Gironde(ca. 5–90 fmol l−1). Additionally,estuarine anoxic sediments were found tocontain large amount of such volatile tinspecies.
