Dr. Allan A. Jensen – lecture on brominated flame retardants

Dr. Allan Jensen from the Nordic Institute of Product Sustainability in Denmark took a lecture “Hexabromocyclododecane (HBCDD) – A brominated flame retardant of high concern” addressing an important environmental problem of brominated flame retardants on Wednesday the 30th March at 1 p.m. at our Research Centre for Toxic Compounds in the Environment.

Dr. Allan A. Jensen – UNEP,SETAC Life Cycle Initiative, FORCE TechnologyAllan Astrup Jensen is PhD organic chemistry from Copenhagen University in 1969. He recently became Research Director and CEO at the Nordic Institute of Product Sustainability, Environmental Chemistry and Toxicology, Denmark. He has about 40 years of professional experience in environmental chemistry and toxicology from employment in universities, not-for-profit institutes and government.
His areas of expertise and interests in chemicals and the environment are broad, and the focus is on the chemical more than the area/compartment. He was responsible for the first source/flow analysis in Denmark of dioxin, PCB/PCT, CFCs, cadmium, and mercury. He still works with various aspects of these and other chemicals (lead, PAH, brominated flame retardants, polyfluorinated compounds, greenhouse gasses, chemical carcinogens). He has made pioneering work with studying chemical contamination of human milk and tissues. He has also been involved in green chemistry and life cycle assessment of chemicals.
He has had scientific and other relations with international organisations such as the European Commission, the European Environment Agency, OECD, WHO/IPCS, WHO/EURO, UNEP DTIE, UNEP Chemicals, SAICM, the Stockholm Convention, the OSPAR Convention, the Helsinki Convention, Nordforsk and Nordic Councils of Ministers.
He was funding chairman of the Danish Society for Environmental Chemistry from 1984-1987 and chairman of FECS/EuCheMS Division on Chemistry and the Environment from 1996-2003. He was organizer of the 6th FECS Conference on Chemistry and the Environment (about air pollution) in Copenhagen, 26-28 August 1998. In addition he was main organizer for the 5th SETAC-Europe Congress in Copenhagen, 25-28 June 1995, with 850 participants. He was recently (2010) co-initiator of a Nordic Network on Fluorinated Compounds in the Environment.
In 2001 he received the Environmental Chemistry Award of the Italian Chemical Society and in 2008 the prestigious EuCheMS Service Award.



HexabromocyclododecaneHexabromocyclododecane (HBCDD or HBCD) is used mainly as a flame retardant in polystyrene-based insulation products. Of particular concern is the capacity of this lipophilic and persistent organic pollutant to accumulate in the food chain, leading to progressively increasing levels in human tissues and in wildlife. The extent of accumulation correlates directly with its ever-more prevalent use. Despite this alarming trend, only limited toxicological information is available to assess its long-term implications for health or the environment. Nevertheless, HBCDD continues to be used despite the availability of alternatives.
The European Chemicals Agency has recently in 2008 identified HBCDD as 1 of 14 substances of “Very High Concern”, and in September 2010 HBCDD was added to REACH’s Authorization List. In February 2011HBCDD was selected to be phased out by EU REACH Regulation.
In October 2010 a committee under the Stockholm Convention has assessed the risks from HBCDD and concluded that HBCDD fulfils the criteria of a persistent organic pollutant (POP), and the committee recommended a global ban of HBCDD use. This presentation provides a succinct up-to date overview of HBCDD’s properties and discusses the risks associated with its prevalence in our homes and immediate environment.
