Trans-boundary movement of e-waste and the associated contaminants (e.g., polychlorinated biphenyls, halogenated flame retardants, metals) has emerged as an important research topic in the last decade. Several monitoring studies published in the peer-reviewed literature have documented elevated levels of various industrial-use organic contaminants (IUOCs) in the atmosphere near known or suspected e-waste receiving and processing sites in Asia. Surprisingly high concentrations of polychlorinated biphenyls in the atmosphere were also reported offshore of West Africa. Emissions of IUOCs linked to trans-boundary movement of e-waste have implications for chemical fate and exposure at local, regional and global scale. For example, the transfer of e-waste from temperate climates to tropical regions could lead to enhanced emissions simply through temperature-related increases in passive volatilization from open landfill sites. The main objective of this study is to develop emission scenarios for selected IUOCs considering the generation and transport of e-waste and simulate and compare chemical fate and transport using an evaluative modeling approach. All simulations were conducted using BETR-Global 2.0 (https://sites.google.com/site/betrglobal/), a chemical fate model which divides the globe into 288 zones (15o x 15o). This spatial resolution is deemed suitable for assessments at the regional as well as global scale. Breivik et al. (SETAC 2014) present an inventory of the global generation and trans-boundary exports of e-waste towards non-OECD countries, with an emphasis on locations in sub-tropical and tropical regions. This inventory along with the physical-chemical property data of selected IUOCs (e.g., partition coefficients, degradation rate constants) are the key inputs to the model simulations. Model output under various emission scenarios are compared in terms of overall persistence (POV) at the global scale as well as in terms of long-range transport potential (LTRP) at regional and global scale (e.g., atmospheric deposition of IUOCs in remote regions). The model outputs are also used to assess the potential implications for chemical exposure at regional and global scale under the various scenarios.

Denne rapporten presenterer resultatene fra en spørreskjemabasert undersøkelse i Wuhan. Ut fra 1086 gyldige spørreskjemaer samlet inn fra offentligheten, viste resultatene at de fleste deltakerne: 1) er unge studenter med bachelorgrad, 2) har grunnleggende kunnskaper om luftforurensningsproblemer i Wuhan, 3) uttrykte vilje til å lære mer om luftkvalitetsrelatert kunnskap; 4) foreslo å styrke miljøholdningsskapende aktiviteter i Wuhan, og 5) på det sterkeste appellere til de lokale myndighetene til å gjennomføre tiltak for å bedre luftkvaliteten.

The MEMORI project (Grant agreement 265132) was performed in the period 2010-2013. The project was coordinated by NILU-Norwegian Institute for Air Research, and included 14 partners, four subcontractors and an advisory end-user group with 8 members. MEMORI aimed at providing the conservation market with innovative, non-destructive, and early warning technology for easy assessment of environmental impact on indoor cultural heritage. For this purpose, a dosimeter and a portable reader instument were produced. In addition, a new web-based result's and presentation mitigation tool was developed.

Environmental Management Report 2013. NILU OR
One of NILU's main goals is to study the impact of pollution. It is thus very important for the institute to have control of the impact the institute¿s own activities may have on the environment and to reduce the impact as far as possible.
NILU has for many years been working to reduce the impact. In order to take this one step further, it was decided that the institute should restructure the work according to a relevant environmental standard and to seek certification according to the same standard.
The chosen standard is ISO 14001:2004 (Environmental management systems - Requirements with guidance for use) and NILU achieved certification according to this standard in October 2010. This report summarizes the results of the system.

Langtransport av miljøgifter med avfall: En giftfri framtid på bekostning av fattige land? NILU F
Det er nå mindre forbudte industrielle miljøgifter i rike industriland som Norge, men nivåene er blitt helsefarlige i deler av Afrika og Asia. I dette foredraget vil du få høre om hvordan kontrolltiltak i rike land kan ha medført at fattige land har blitt en dumpingplass for giftig avfall.
