Contaminants and beach front zones: bits of knowledge from the ELOISE and IMPACTS ventures Knut Breivik, Jozef M Pacyna and Kevin Barrett Center for Ecological Economics Norwegian Institute for Air Research (NILU)

Slide 2

1. Presentation – Overview of undertakings Persistent Organic Pollutants (POPs) ADIOS, AIRWIN, BIOCET, EROS-21 , FAMIZ, POPCYCLING-BALTIC Oil hydrocarbons COMMODE, MATBIOPOL Other ACE (antifouling operators), SUB-GATE (methane) Projects part of the ELOISE group are given in italic , different tasks have a place with the IMPACTS bunch

2. Contextual analysis: POPCYCLING-Baltic venture The general objective of the RTD venture "POP-CYCLING-BALTIC" was to build up a complete, multicompartmental model to ponder the destiny and conduct of POPs in the Baltic Sea environment (Pacyna et al 1999 ) Specific goals comprehend and measure the significant sources, pathways and misfortune procedures of the contaminants set up a connection between contaminant loadings and natural fixations evaluate the time reaction to stacking decreases decipher spatial examples and transient patterns of the sullying

Contextual investigation: POPCYCLING-Baltic venture The POPCYCLING-Baltic Model plans to evaluate the pathways of POPs from the earthbound environment to the marine environment by means of climate and streams (Wania et al 2000) The model is uninhibitedly accessible for download at www.scar.utoronto.ca/~wania

2. Contextual analysis: POPCYCLING-Baltic undertaking Model assessment for two HCHs (Hexachlorocyclohexanes) Breivik and Wania, 2002a a - HCH measured demonstrated g - HCH measured displayed Spatial examples: measured (Gaul, 1992) and displayed surface water focuses in ng/L amid the late spring of 1983 and 1988.

2. Contextual analysis: POPCYCLING-Baltic task Air fixations Seawater focuses a - HCH Breivik and Wania, 2002a g - HCH

Slide 11

2. Contextual investigation: POPCYCLING-Baltic venture measured herring versus demonstrated ocean water focuses (1987-1997) measured pike versus demonstrated new water focuses (1970-1996) Breivik and Wania, 2002a The model imitates the time patterns of a - HCH saw in air, ocean water and crisp water fish. The abatement of g - HCH focus anticipated by the model happens sooner than is seen in nature.

2. Contextual investigation: POPCYCLING-Baltic venture Relative Importance of HCH Sources Within and Outside of the Baltic Sea Drainage Basin a - HCH, 1970 to 2000 g - HCH, 1970 to 2000 discharge 19.3 kt emanation 4.5 kt Baltic Sea environment Baltic Sea environment climatic surge 32.1 kt barometrical outpouring 9.6 kt air inflow 29.4 kt air inflow 9.5 kt maritime surge 0.6 kt maritime outpouring 0.6 kt maritime inflow 0.5 kt maritime inflow 0.5 kt The model proposes that immediate use inside the Baltic Sea waste bowl represents around 30 to 40 % of the aggregate sum of HCHs entering this environment. The rest of because of utilization outside of the waste bowl. The waste bowl in general is a net exporter of both a - HCH and g - HCH. The relative significance of sources inside the bowl has diminished in time. On account of g - HCH, the commitment from sources inside the waste bowl diminished from 40 to 10%. Amid the 1980s, the Baltic Sea district changed from being a net exporter to being a net beneficiary of g - HCH. Breivik and Wania, 2002b

2. Contextual investigation: POPCYCLING-Baltic undertaking What did we achieve ? A quantitative photo of the long haul (decades) destiny of a semi - unstable and constant natural synthetic in a huge oceanic framework and its waste bowl real supplies major pathways (e.g. riverine versus environmental, vertical versus flat) balance status and flux heading significance of sources inside versus outside seepage bowl time reaction in different media
