The Inter-laboratory Comparison on determining Mercury and Chloride in Water (2023) was jointly implemented by Water Quality Analysis Laboratory, Research Center for Eco-Environmental Sciences (RCEES), Chinese Academy of Sciences (CAS) and Centre of Excellence for Water and Environment (CEWE), CAS-TWAS in 2023. It is a great honor to undertake this important activity for the fifth round, with full support from the Certification and Accreditation Administration of the People's Republic of China, CNCA (Approved as CNCA[2023]37) and the Alliance of International Science Organizations (ANSO-CR-KP-2020-05).

This study was conducted to determine the levels of mercury and chloride in two different water items. Both water samples were distributed to the participating laboratories with two testing samples at the same concentration, respectively.
