Abstract A sediment reference material (S-37) was prepared as analytical quality control material to be used within an international project on polychlorinated hydrocarbon analysis in two Chinese rivers. The raw material was sampled during a cruise on Yangtse River and transported afterwards to the JRC Ispra for further processing. The material was treated according to the general principles applicable for candidate reference material production. After a thorough homogeneity study of the bulk the material was bottled. A total of 1080 bottles each containing 50 g of dry sediment powder was obtained. Final homogeneity and stability testing proved the material to be fit for the purpose. Isotope dilution GC/MS was used to establish target values for pentachlorobenzene (1.17 ± 0.08 ng/g), hexachlorobenzene (3.60 ± 0.17 ng/g), octachlorostyrene (0.19 ± 0.01 ng/g), pentachloroanisole (0.52 ± 0.02 ng/g), α-HCH (0.70 ± 0.05 ng/g), β-HCH (1.38 ± 0.18 ng/g), γ-HCH (0.83 ± 038 ng/g), 2,4′-DDT (0.36 ± 0.04 ng/g), 2,4′-DDE (0.29 ± 0.02 ng/g), 2,4′-DDD (0.49 ± 0.02), 4,4′-DDT (3.42 ± 0.47 ng/g), 4,4′-DDD (1.29 ± 0.17 ng/g), PCB 28 (0.11 ± 0.01 ng/g), PCB 52 (0.09 ± 0.003 ng/g), PCB 101 (0.07 ± 0.003 ng/g), PCB 138 (0.06 ± 0.003 ng/g) and PCB 153 (0.06 ± 0.003 ng/g). Furthermore, indicative values for major and minor constituents as well as for polychlorinated dibenzodioxines and -furanes were measured.
