“…These results correspond also to the conclusions presented by e.g. Berg et al (2001), Burton et al (2004), Fent (1996 or Hoch and Schwesig (2004), who suggested that OTs are more likely to bind to fine particles associated with higher organic carbon content, as humic acids readily form complexes with OTs.…”

Sediment samples were collected in two Polish ports of international significance-the Port of Gdańsk and the Port of Gdynia (Gulf of Gdańsk, Baltic Sea)-in order to assess their butyltin and phenyltin contamination; this was done in 2008, just after the total ban on using harmful organotins in antifouling paints on ships came into force. Altogether, 21 sampling stations were chosen to present a diversity of port sites: from port canals and shipyards to anchorages and dumping sites. The organic carbon content and grain size of all the sediment samples were determined, and some environmental parameters (oxygen content, salinity) were measured as well. Total concentrations of butyltin compounds in sediment samples were very different and ranged between 1 and 18,520 ng Sn g −1 d.w. Phenyltin

“…Several of cytotoxicity assays have been employed for the evaluation of environment pollutants (Fent andHunn 1996, Putnam et al 2002). They have a different mechanistic basis, and thus may give some hints as to the biochemical mechanism of toxic action.…”

Abstract. A battery of in vitro bioassays, including a Neutral Red (NR) assay using MCF-7 cells for predicting cytotoxic chemicals, an ethoxy resorufin-O-deethylase (EROD) activity assay using H4IIE cells to check for dioxin-like chemicals, and a recombinant gene yeast assay for screening estrogenic chemicals, was conducted to assess the removal efficiencies of trace toxic chemicals by different treatment processes in the waste water treatment plant (WWTP). The effluents were extracted by solid phase extraction (SPE) and were fractionated into three fractions based on polarities. The battery of bioassays was performed for each fraction. In the battery, the toxicities of the effluents were described according to their modes of actions (MOA) or biomarkers and the properties of the toxic chemicals were categorized by their polarities and MOAs. The proposed procedure could be used as a tool to diagnose the toxic characteristics of the complicate mixture. The results showed that cytotoxic, dioxin-like and estrogenic chemicals could be detected in all samples. In the influent, cytotoxic and dioxin-like chemicals were mainly in polar fraction and estrogenic chemicals were in non-polar and moderate-polar fractions. The secondary treatment (active sludge) could remove a small amount of these toxicants. Among different types of advanced treatments, flocculation was good enough to remove most of the cytotoxic chemicals and a combination of flocculation, ozone oxidation, and post-biological treatment could eliminate most of the dioxin-like and estrogenic chemicals.

“…Extensive applications of methyltin compounds as biocides, antifouling agents and polyvinyl chloride heater stabilizers have caused serious pollution to the environment because of their high toxicity to organisms [1,2]. Up to date the occurrence of methyltin compounds have been found in many different environmental media such as seawater [3,4], river water [5,6], lake water [6,7], sediments [8] and biological samples [3].…”

“…Up to date the occurrence of methyltin compounds have been found in many different environmental media such as seawater [3,4], river water [5,6], lake water [6,7], sediments [8] and biological samples [3]. In addition to the anthropogenic sources [1], methyltins can be produced by the biotic and abiotic methylation [9][10][11].…”

a b s t r a c tA novel on-line coupled HPLC-hydride generation (HG)-ICP/MS system was developed for rapid, direct and sensitive speciation of methyltins in seawater without any pretreatment step. Methyltin compounds were separated by reversed phase HPLC, and then on-line reacted with potassium borohydride and acetic acid to generate volatile hydride products. The volatile derivatization products were separated in the spray chamber of ICP/MS and then introduced into ICP/MS by argon gas for detection. Monomethyltin (MMT), dimethyltin (DMT) and trimethyltin (TMT) were baseline separated in less than 15 min by reversed phase HPLC. The influence of KBH 4 concentration and type of acid on the system performance was investigated and optimized. Calibration curves, based on peak heights against concentration, were linear in the range of 0.5-50 ng (Sn) mL −1 of methyltins with correlation coefficients of 0.9990, 0.9990 and 0.9996 for MMT, DMT and TMT, respectively. The relative standard deviations measured at 10 ng (Sn) mL −1 for these three methyltins were in the range of 0.6-1.4% (n = 5), and the calculated detection limits (S/N = 3) for MMT, DMT and TMT were 0.266, 0.095 and 0.039 ng (Sn) mL −1 , respectively. This method was successfully applied to the speciation of methyltins in seawater with spiked recovery in the range of 95.4-106.9%. MMT and DMT were detected in all the seawater samples with concentrations in the range of 1.0-1.5 and 0.30-0.57 ng (Sn) mL −1 for MMT and DMT, respectively.
