Summary

Organotin compounds like tributyltin (TBT) and triphenyltin (TPT) show variable stability. Optimal storage for butyltins and phenyltins involves freezing or freeze-drying, especially for complex matrices like sediment and seafood.

Area of Science:

  • Environmental Chemistry
  • Analytical Chemistry
  • Marine Biology

Background:

  • Organotin compounds (TBT, TPT) are persistent organic pollutants.
  • Accurate monitoring requires understanding analyte stability during storage.
  • Previous studies show limited data on long-term organotin stability in diverse matrices.

Purpose of the Study:

  • To evaluate the stability of tributyltin (TBT) and triphenyltin (TPT) in various environmental samples.
  • To determine optimal storage conditions for organotin analysis.
  • To assess the impact of different storage durations and conditions on organotin concentrations.

Main Methods:

  • Samples of seawater, sediment, oysters, and cockles were analyzed for TBT and TPT.
  • Storage conditions included refrigeration, freezing, freeze-drying, and various preservation techniques.

  • Samples were analyzed over an 18-month period using unspecified analytical methods.

    • Main Results:

    • Butyltins were stable in seawater at 4°C for 7 months, but degraded over 540 days.
    • Phenyltins showed significant losses in seawater within 60 days under various storage conditions.
    • Organotins remained stable in sediments stored at -20°C for 18 months.
    • Air-drying and pasteurization improved sediment storage at higher temperatures but still resulted in TBT loss.
    • Butyltins were stable in frozen seafood for 7 months, with losses observed in freeze-dried samples.

    Conclusions:

    • Storage conditions significantly impact organotin stability, with freezing being generally optimal.
    • Seawater and seafood require careful storage (e.g., freezing) to prevent organotin degradation.
    • Sediments are more stable, particularly when stored frozen, but higher temperature storage requires stabilization treatments.
    • Long-term monitoring of organotins necessitates validated storage protocols tailored to the specific matrix.
