Alternative approaches to standard toxicity testing. TQP ID 9-OPTION-257430181-NILU. NILU OR
An amine based CO2 capture plant may cause harmful emissions to the atmosphere. Amines and degradation products from reactions in the process and in the atmosphere are of particular concern, but there is limited knowledge about the behaviour and potential effects of these chemical compounds. The substances produced can pose a risk to the environment and human health. This report is an option for the TQP ID 9 - 257430120 - NILU report (or 14/2011) and includes a review on nitrosated and nitrated amino acids with detail physicochemical data and (eco)toxicological endpoints for these substances. Furthermore evaluation of toxicological concepts and parameters related to risk assessment of these compounds, such as mutagenic potency, DNEL/DMEL and TD50/T25, has been provided. An evaluation of the use of a new developed QSAR model to predict TD50 of an extended list of nitrosamines was performed. In addition a current knowledge status on the use of (Q)SAR within REACH have been carried out.

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.

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.

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.
