Abstract A mixture of 50% H2O2–H2SO4 (3 + 1, v/v) was used for decomposition of food in open vessels at 80°C. The treatment allowed rapid total mercury determination by flow injection cold vapor atomic absorption spectrometry. Cabbage, potatoes, peanuts paste, hazelnuts paste, oats, tomatoes and their derivatives, oysters, shrimps, prawns, shellfish, marine algae, and many kinds of fish were analyzed by the proposed methodology with a limit of quantitation of 0.86 ± 0.08 μg/L mercury in the final solution. Reference materials tested also gave excellent recovery.

An investigation of the natural products chemistry of the red alga Laurencia mujuscula from the Great Barrier Reef yielded three novel metabolites, (1), (2) and (3a), possessing a new sesquiterpenoid structural type. Known metabolites (6)-(11) were also isolated and the reassignment of n.m.r. spectral values for (11) is reported.
