Akrylamid i utvalgte næringsmidler 2011. NILU OR
NILU - Norsk institutt for luftforskning har på oppdrag fra Mattilsynet utført bestemmelse av akrylamid i 141 matvarer. Prøveinnhenting ble utført i perioden juni-november 2011 og omfattet potetprodukter, kornprodukter, barnemat, kaffe og tørket frukt.

NILU performed a test campaign for measurements of CF4 and C2F6 for stack emissions at Alcoa Mosjøen Smelter. Time-integrated samples were taken with evacuated canisters combined with low-flow restrictors for continuous sampling periods as long as 4 weeks. The samples were analyzed at NILU with a Medusa preconcentration method combined with GC-MS SIM. As a main conclusion, time integrated sampling together with Medusa GC-MS methodology is a very precise alternative to the traditional attempts to quantify PFC-emission.

Pollutants emitted by industrial processes are deposited across the landscape. Ice core records from mid-latitude glaciers located close to emission sources document the history of local-to-regional pollution since preindustrial times. Such records underpin attribution of pollutants to specific emission sources critical to developing abatement policies. Previous ice core studies from the Alps document the overall magnitude and timing of pollution related to nitrogen and sulfur-derived species, as well as a few metals including lead. Here, we used subannually resolved measurements of vanadium (V) and molybdenum (Mo) in two ice cores from Col du Dome (French Alps), as well as atmospheric transport and deposition modeling, to investigate sources of pollution in the free European troposphere. The noncrustal V and Mo (ncV, ncMo) components were calculated by subtracting the crustal component from the total concentration. These ice core results showed a 32-fold increase in ncV and a 69-fold increase in ncMo from the preindustrial era (pre-1860) to the industrial concentration peaks. Anthropogenic V and Mo emissions in Europe were estimated using emission factors from oil and coal consumption and atmospheric transport and deposition modeling. When comparing ice core data to estimated anthropogenic V and Mo emissions in Europe, V was found to be sourced primarily from oil combustion emissions. Conversely, coal and oil combustion estimated emissions did not agree with the measured ice core Mo concentrations, suggesting that other anthropogenic Mo sources dominated coal-burning emissions, particularly after the 1950s. Noncoal-burning sources of Mo may include metallurgy although emission factors are poorly known.

Alternative approaches to standard toxicity testing, TQP ID 9 - 257430120 - NILU. NILU OR
Et aminbasert CO2 renseanlegg kan føre til utslipp av aminer til luft. I atmosfæren brytes aminer ned til mange ulike kjemiske forbindelser, deriblant til nitrosaminer og nitraminer. Disse kan ha miljø- og helseskadelige egenskaper. Denne rapporten gir en oversikt over eksisterende data for nitrosaminer og nitraminer og en anbefalning til integrert strategi for testing ved bruk av alternative metoder som in vitro metoder og (Q)SAR for å fylle kunnskapshullene og informasjonskravene for risikovurdering av kjemikalier i REACH.
