Effect of copper ions on the degradation of thiram in aqueous solution: Identification of degradation products by HPLC-MS/MS

- Cu(II) in excess accelerates the degradation of thiram in aqueous solutions.
- The [CuThi]2+ complex degrades into [(DMDTC)Cu]+ which readily decomposes.
- New degradation products of [CuThi]2+ were identified for the 1st time by HPLC-MSn.
- Some degradation products are quite persistent, at least during 2 months.
