Maria B. de la Calle1, Vicenta Devesa2, Yiannis Fiamegos1, Dinoraz Vélez2 1European Commission, Joint Research Centre, 2Metal Trace Element Laboratory, IATA-CSIC The usefulness of an analytical method to determine inorganic arsenic in a wide range of food matrices is demonstrated. The method consists of selective extraction of inorganic arsenic into chloroform with a final determination by hydride generation-atomic absorption spectrometry. Environment Implementation of Portable Emissions Measurement Systems (PEMS) for the Real-driving Emissions (RDE) Regulation in Europe Barouch Giechaskiel1, Theodoros Vlachos1, Francesco Riccobono1, Fausto Forni1, Rinaldo Colombo1, Francois Montigny1, Philippe Le-Lijour1, Massimo Carriero1, Pierre Bonnel1, Martin Weiss1 1Sustainable Transport Unit, Institute for Energy, Transport and Climate, Joint Research Centre The European Commission has developed a Real-Driving Emissions (RDE) test procedure to verify pollutant emissions during real-world vehicle operation using the Portable Emissions Measurement Systems (PEMS). This paper presents the experimental procedures required by the newly-adopted RDE test.
