Recently a mussel certified reference material has been produced for the quality control of the determination of MBT, DBT and TBT (Morabito et al., 1999). The use of this material will certainly help to improve the data quality produced in the chemical speciation of butyltins. 

The programme to improve the quality control of organotin determinations in environmental matrices started in 1988 [9] by a consultation of European experts. It was decided to follow a stepwise approach for the evaluation of the performance of methods used in butyltin analyses. The overall programme consisted in a series of interlaboratory studies which started by an intercomparison on organotins in solutions followed by an intercomparison on a TBT-spiked sediment.
