An improved sample preparation procedure for analysis of carcinogenic ethyl carbamate (EC) in wine by GC–MS–SIM is proposed. Differences over AOAC reference procedure were: (1) use of EC-d 5 as internal standard instead of less similar propyl carbamate; (2) extraction by diethyl ether instead of more toxic dichloromethane, and (3) concentration by vacuum automated parallel evaporation instead...
The present study, carried out in a mercury (Hg) contaminated estuary, aimed to investigate: (i) the long-term evolution of the Hg bioavailability in the environmental matrices, in a period of 5years (2003–2008), without new anthropogenic inputs; (ii) the temporal evolution of Hg load (organic and inorganic forms) in the native bivalve Scrobicularia plana, inferring the progression of human health...
