Mercury is a metal found naturally in the environment but it also comes from human activities such as metallurgy or waste combustion.
In the environment, mercury can be in the water or sediment in its organic form called Methylmercury.
This particularly toxic form of mercury is better assimilated by organisms than inorganic mercury can concentrate in high concentrations in aquatic organisms.
At present, European legislation does not set limits for this substance but a study has already been completed by EFSA and concluded the need to regroup others datas.
The CODEX has established thresholds on fish at 0.5mg/kg and 1mg/kg on fish predators (CODEX STAN 193-1995).
The fishery products are not the only ones affected by methylmercury matrices, in December 2015, chapter of USP pharmacopoeia “<561> Articles of botanical origins” on herbal drugs (dried plants) will be changed. A specific limit for Methylmercury will be set at 0.2mg/kg.
Our R & D department has recently developed a analysis method for Methylmercury by LC-ICP/MS to a LOQ of 0.02mg/kg. In the contexte of our flexible scope for heavy metals program (99-3), COFRAC has validated accreditation of this parameter on the following matrices: Fishery products, Fruits and Vegetables, Medicinal plants, Food supplements and Feed.
