Welcome to the April issue of EVISA's Speciation Newsletter !
The history of speciation analysis began with the identification of organometallic species that gained notoriety, such as methylmercury (Minamata, 1959) and tributyltin (Bay of Archachon, 1986), both of which made significant headlines. Despite advancements in speciation analysis since then, these issues have not been fully eradicated. Regarding tributyltin (TBT), an international convention addressing the control of harmful anti-fouling systems (AFS) on ships was implemented in 2008 to prevent the use of organotin-containing paints. However, even post-2008, TBT continues to be detected in numerous harbors and coastal areas, either due to ongoing introduction or the slow degradation of existing deposits.
Although the use of TBT in antifouling paints has been prohibited, global production of organotin compounds has continued to increase by approximately 5% annually, now amounting to a market value of approximately USD 2.1 billion. These compounds find application primarily as catalysts for forming products like polyurethane foams, as heat and PVC stabilizers, and as biocides. Given their significant toxicity even at low concentrations, they are subject to broad regulatory oversight, including occupational exposure limits. Because toxicity can vary based on structural characteristics, speciation analysis is crucial for accurate risk assessment.
During manufacturing processes, organotin compounds (OTCs) can be emitted as vapors or dust particles. Interestingly, specific compound-focused methods for monitoring workplace exposure are currently lacking. However, this gap has recently been addressed by a team of German researchers who developed a liquid chromatographic method capable of separating organotin compounds present in workplace air. This innovative approach utilizes advanced High-Performance Liquid Chromatography-Inductively Coupled Plasma Mass Spectrometry (HPLC-ICP-MS) to accurately quantify 11 specific organotin species in less than 22 minutes (see details in the news article mentioned below).
