About Andreas

Traditional chemicals risk assessment has a quite artificial orientation: It treats chemicals as if they act in isolation, when in reality there is exposure to multiple substances. For more than 15 years, our team have been engaged in efforts to find ways of improving risk assessment by taking “cocktail effects” into account. This work has proceeded in stages: Firstly, when we have information about the toxicity of individual mixture components, is it possible to predict the effects of the combination? Working with mixtures of endocrine disrupting chemicals we have shown that this is achievable. Secondly, what is the composition of mixtures of environmental relevance, and what effects do they produce? Work on this aspect of the mixtures issue is currently proceeding in our group. We are also interested in making an impact on chemical regulation by addressing the questions: Which chemicals should be grouped together for mixtures risk assessment? What are scientifically sound grouping criteria?

We have prepared scientific reports for the European Commission, including the State of the Art Report on Mixture Toxicology. Currently we are writing a State of the Art Assessment for Endocrine Disrupters, a project also commissioned by the European Commission.

Another research interest is in unravelling the details of estrogen signalling and estrogen-mediated effects with a view to understanding hormonal cancers, especially breast cancer. Here, I closely collaborate with Dr Elisabete Silva.

Research Activity

Research Projects

My research interest falls into three broad areas: understanding the combined effects of mixtures of environmental pollutants on human health and wildlife, developing strategies for handling mixtures in chemicals regulation, and dissecting the events important in hormonal carcinogenesis.

1. Understanding combination effects of mixtures

Not long ago, the topic of mixture effects of chemicals was deemed too difficult to be approached experimentally. There has been, and still is, a confusion of important terms and concepts in mixture toxicology, as well as experimental approaches. We have tried to understand mixture effects in terms of the toxicity of individual mixture components: Is it possible to predict accurately the effects of a mixture, when we have information about the toxicity of its components, and of the mixture ratio?

Another issue arising from the experimental mixture studies is: How many chemicals are humans or wildlife exposed to simultaneously, and which of these contribute substantially to a specific combination effect? We are currently pursuing this problem by investigating mixtures that are modelled on realistic exposure scenarios.

2. Regulatory strategies for dealing with mixtures

A new consensus is emerging that mixture effects should be the topic of chemicals risk assessment. Any strategy for dealing with combination effects has to address the question: Which chemicals should be grouped together to be subjected to mixtures risk assessment? There are at least two approaches to resolving this question: Firstly, those chemicals that humans and wildlife come into contact with simultaneously should be considered. Secondly, chemicals that can produce similar adverse outcomes should also be grouped together. Our team is engaged in developing viable, pragmatic grouping criteria for chemicals in mixture risk assessment.

3. Hormones and hormonal carcinogenesis

While it is clear that hormones play a role in cancers of the breast, prostate and testes, their precise involvement in the disease process is far from clear. Our team is interested in studying the details of cell division and differentiation, and the role that steroid hormones and other hormonally active chemicals play in these processes. Here, we are collaborating closely with Dr Elisabete Silva.

Impact

Our work is beginning to have significant political impact at the European Union level: In 2008 the Danish Government charged us with organizing an international workshop on combination effects of chemicals (28-30 January 2009, Hornbaek, Denmark)

The outcomes of this workshop were taken forward by the Danish Government to the European Council and have contributed to the Decision of the European Council of Environment Ministers of December 2009 on combinations effects of chemicals.

In December 2007 the European Commission, DG Environment commissioned a State of the Art Report on Mixture Toxicology which a consortium under our leadership won by competitive tender. The report was completed in December 2009 and was explicitly referred to in the European Council decision on combination effects of chemicals.
