(b) Hazard assessment for endpoints of concern, including consideration of toxicological interactions involving multiple chemicals (provide summary information and relevant references)






(c) Environmental fate (provide summary information and relevant references)

Chemical/physical properties




Persistence




How are chemical/physical properties and persistence linked to environmental transport, transfer within and between environmental compartments, degradation and transformation to other chemicals?




Bio-concentration or bio-accumulation factor, based on measured values (unless monitoring data are judged to meet this need)







(d) Monitoring data (provide summary information and relevant references)

EXPOSURE DATA and LRT-information:
Environmental pollutants in endangered vs. increasing subspecies of the lesser black-backed gull on the Norwegian coast. Bustnes J.O., Helberg M., Strann K-B., Skaare, J. U. Environmental Pollution 144 (2006) 893-901.
Organochlorine (OC) residues were measured in eggs and blood of different subspecies of the lesser black-backed gull, Larus fuscus, on the Norwegian coast: a) increasing L. f. intermedius in the North Sea; b) endangered L. f. fuscus near the Arctic Circle; c) L. f. fuscus and greyish mantled gulls, with a L. f. intermedius appearance,m in the Barents region. Relative high levels of beta-HCH were found in L.f. fuscus.

The levels of DDE and beta-HCH wqs higher in an endangered than in an increasing subspecies of lesser black-backed gulls in Norway.

The article concludes that even if the use of technical HCH, that contains beta-HCH, has decreased over the globe the two last decades the levels of beta-HCH is still relative high in many areas. L.f. fuscus migrates through the Black Sea area, considerably contaminated with HCH. The levels found can therefore be a result of this migration.

(Jfr Stockholm Convention 1 (d) (ii) in Annex D.)





(e) Exposure in local areas (provide summary information and relevant references)

- general



- as a result of long range environmental transport


- information regarding bio-availability






(f) National and international risk evaluations, assessments or profiles and labelling information and hazard classifications, as available (provide summary information and relevant references)






(g) Status of the chemical under international conventions
