Fengjiao Peng (at 11.00h):
The PhD thesis of Fengjiao Peng is entitled “Ecological risks of personal care ingredients for subtropical benthic invertebrates”. Her thesis consists of two chapters on a chemical and biological monitoring study performed in sub-tropical China, and four chapters on the results of microcosm studies performed using benthic invertebrates to assess the effects of personal care ingredients on the benthic invertebrates and the microbial community, the influence of benthic invertebrates on the fate of the chemicals as well as their bioaccumulation and biotransformation in benthic invertebrates. Paul will be the promotor and Professor Guang-Guo Ying from the South China Normal University will be the co-promotor.
Kizar Sumon (at 16.00h)
The PhD thesis of Kizar Sumon is entitled “Effects of insecticides on aquatic ecosystems in Bangladesh”. His thesis consists of one modelling chapter evaluating the ecological risks of pesticide use in rice-prawn systems in Bangladesh, one chapter on a chemical monitoring programme on the risks of insecticides, one chapter on a microcosm study performed with imidacloprid in Bangladesh and two chapters on the effects of chlorpyrifos on fish. Paul will be the promotor and Dr. Roel Bosma (AF-WU, Dr. Edwin Peeters (AEW-WU) and Dr. Harunur Rashid (Bangladesh Agricultural University) will be the co-promotors.

Dissertation title: Sediment toxicity testing and prospective risk assessment of organic chemicals
Group: Wageningen University, Aquatic Ecology and Water Quality Management
Promotors: Prof.dr. A.A. Koelmans
Copromotors: Prof.dr.ir. P.J. van den Brink
Sediment-dwelling organisms are at potential risk due to polluted sediments. Although some well-established sediment tests exists for a few species there is a lack of cost-effective and widely accepted methods to assess potential effects on different taxonomic groups, between freshwater, estuarine, and marine ecosystems and at the population and community level. In addition, spatio-temporal extrapolation of test results requires mechanistic understanding of exposure pathways and effects, as well as prospective models. Therefore, the aim of this study is to develop improved methods and assess potential effects of contaminated sediments on aquatic microorganisms, plants, and invertebrates within and across different taxonomic groups, which can be applied in a regulatory context.
Interview in Dutch on how waterboards could improve the evaluation of their chemical and biological monitoring data
Wageningen University has appointed Professor Paul van den Brink to a Personal Professorship in Chemical Stress Ecology with effect from 1 June 2015. This chair will be part of the Aquatic Ecology and Water Management Group.
Professor Paul van den Brink (Oss, 1968) studied Environmental Hygiene in Wageningen. After graduating in 1992, he began working as a researcher at Alterra Wageningen UR. In 1999, he received his PhD at Wageningen University for his research into the effects of pesticides in surface water. In 2005, Van den Brink was seconded part-time to Wageningen University, and in 2008 he was appointed to a Special Professorship in Chemical Stress Ecology for 1 day per week. As a newly appointed Personal Professor, Van den Brink will now be appointed to the university full time. He continues to focus on the ecological side effects of chemicals such as pesticides, cleaning agents, personal care products and pharmaceuticals in the aquatic environment in Europe, Asia and Africa.
In 2006, Prof. Van den Brink received the SETAC Innovative Science Award from CEFIC-LRI, and between 2008 and 2012 was a member of the World Council of the Society of Environmental Toxicology and Chemistry (SETAC). Since 2012 he has also been an Honorary Visiting Professor at the University of York (UK).
Paul gave a keynote at the SASAqS 2015 meeting in Drakensberg, South Africa on “Diagnosis of field impacts of chemicals from monitoring and experimental data.” See Keynote SASAqS PvdB 2015 for the slides.
