This review highlights that while inorganic tin has low toxicity, organotin compounds pose significant risks. Bioavailability and ecotoxicity of organotins in aquatic environments are influenced by factors like pH and dissolved organic carbon.

Area of Science:

  • Environmental Chemistry
  • Toxicology
  • Ecotoxicology

Background:

  • Tin exists in metallic, inorganic, and organotin forms, with varying toxicological profiles.
  • Inorganic tin and metallic tin exhibit low toxicity, whereas organotin compounds are recognized for their toxicological relevance.
  • Organotin compounds, particularly triorganotins, are widely used as biocides due to their high toxicity.

Purpose of the Study:

  • To review the existing literature on the bioavailability of tin, inorganic tin compounds, and organotin compounds.
  • To elucidate the factors influencing the bioavailability and ecotoxicity of organotin compounds in aquatic ecosystems.
  • To assess the environmental fate and distribution of organotin compounds in organisms.

Main Methods:

  • Literature review of scientific articles and studies on tin bioavailability and toxicity.

  • Analysis of factors affecting tin speciation and bioavailability in aqueous systems.
  • Examination of degradation pathways (biotic and abiotic) and partitioning processes (adsorption/desorption) of organotin compounds.
  • Evaluation of bioconcentration and biomagnification of organotin compounds in aquatic organisms.

    • Main Results:

    • The bioavailability of tin in aqueous systems is linked to the concentration of dissolved tin ion species.
    • Organotin compounds, especially triorganotins, demonstrate significant toxicity and are widely applied as biocides.
    • Persistence of organotins is influenced by aerobic and anaerobic degradation, photolysis, and adsorption processes.
    • Organotin compounds are widespread in aquatic organisms, with bioavailability and ecotoxicity dependent on the bioavailable fraction.
    • Bioavailability is optimal at neutral to alkaline pH and decreases with higher dissolved organic carbon.
    • Bioconcentration from water is a more significant pathway than biomagnification through the food chain for organotins.

    Conclusions:

    • Organotin compounds present a considerable toxicological concern in aquatic environments.
    • Environmental factors such as pH and dissolved organic matter critically modulate organotin bioavailability and ecotoxicity.
    • While inorganic tin has low toxicity, the widespread use and persistence of organotins necessitate careful environmental monitoring and management.
