VU Plastic pollution research in spotlight at Plastic Health Summit
4 October 2019
The VU’s plastic pollution scientists Dr. Heather Leslie and Prof. Dr. Dick Vethaak (VU and Deltares) made important contributions to plenary session of the Plastic Health Summit on 3 October 2019 in Amsterdam.
E&H SYMPOSIUM ‘WASTE – A MATTER OF TASTE’, 3 DECEMBER 2019
A growing world population with intensive economies, global markets and increasing transport is creating enormous piles of waste. Up to 2015, over 6 billion tons of plastic waste were produced by humans, which is equivalent to 60 million blue whales. While wastewater treatment plants and incinerators exist as waste management strategies, materials and chemicals that do not degrade easily are still being produced. How do we deal with all that waste? Can we recycle waste to safe consumer products in circular economies? What kind of chemicals end up in the waste or recycled products? What are the effects of chemicals in waste on our environmental resources and our health?
Following two earlier successful symposia, the VU department of Environment & Health is organizing a symposium on 3 December 2019 under the title Waste – a Matter of Taste to discuss these issues with scientists, authorities and industry representatives. The full-day program is designed to pose thought-provoking questions, and will provide ample opportunity for discussion and networking with scientists, health professionals and other stakeholders. More information will be announced later. Please save the date!

Discussion on flame retardants in Science continues
10 September 2019
The article of Jacob de Boer and Heather Stapleton in Science from April 2019 (Vol. 364, Issue 6437, pp. 231-232) generated a letter to the editor by authors from the North American Flame Retardant Alliance. They claim that there are clear differences between flame retardants and not all halogenated flame retardants are toxic. This letter and the rebuttal of de Boer and Stapleton appeared Friday 6 September in Science (Vol. 365, Issue 6457, pp. 993).
The discussion continues with the reaction of a colleague which also has been published in Dutch regional newspapers.

European experts on micro- and nanoplastic analysis convene to discuss state-of-the-art
14 May 2019
In Ispra, Italy (13 and 14 May 2019) key European scientific experts in micro- and nanoplastics analysis met with diverse EC Joint Research Centre scientists and managers, representatives of European Commission DGs, European Chemicals Agency (ECHA) and European Food Safety Authority (EFSA) to present the state of the art in micro- and nanoplastics analysis in real world samples. The workshop was billed as “State-of-the-art of analytical methods for reliable detection of micro- and nanoplastics” and quality assurance and quality control of both sampling and analysis were hot topics.
E&H microplastics expert Dr. Heather Leslie presented the microplastics interlaboratory study that was initiated by VU E&H and is currently ongoing in collaboration with NIVA, QUASIMEME and the NORMAN network. There is intensive interest in this area at the European level as well as for researchers from academia to commercial labs who are seeking to improve their laboratory performance and validate their analytical methods. VU E&H is pleased to collaborate with our existing and future partners on analysis and development of QA/QC tools such as interlaboratory studies, development exercises and the preparation of reference materials in order to bring our understanding of microplastics in environmental, human and consumer product matrices to the next level.
The group agreed that the way forward for microplastics analysis includes more attention to analytical development, increasing opportunities for equipment sharing/purchasing, developing more QAQC tools, and later on down the road, formal standardization of methods. It was also noted that without standardized methods there is already enough information available to draft and implement legislation concerning microplastics such as the EU Marine Strategy Framework Directive (MSFD), various bans on microbead in cosmetics worldwide, voluntary phase outs, and the most recent proposal to regulate intentionally added microplastics submitted the EC by the ECHA. For answering burning research questions and for strengthening the evidence base of the risks of micro and nanoplastics, continued investments in micro- and nanoplastic analytics are essential.

"Harmful fire retardants must be banned"
23 April 2019
Authorities should prohibit industry from continuing to produce harmful flame retardants, as there are good alternatives. This is advocated by VU professor Jacob de Boer in an opinion piece in Science. Already in 1998 De Boer and colleagues published in Nature about the dangers of fire retardants with halogens in them. The halogens in fire retardants - for example, chlorine, bromine and fluorine - are harmful to humans and the environment. Now, more than twenty years later, only three harmful substances are banned. Dozens of other halogen-containing fire retardants are still being produced. Read more (in Dutch)

PLASTIC SOUP CHILDREN’S LECTURE AT NEMO SCIENCE MUSEUM
The children performed simple experiments exploring plastic’s behaviour in the environment and products. At the end of the hour, they used their knowledge of plastic pollution prevention in designing their own cookie packages that were specially devised to never become part of the plastic soup. The next generation of plastic soup scientists already understand the problems – and they appear to have moved on to solving them.
A report of the lecture can be found here along with NEMO’s schedule for other spectacular children’s science lectures, which take place once a month on a Sunday at 11 AM and 1PM. In Dutch.

ECOSYSTEM MODELLING OF MICROPLASTICS IMPACT PUBLICATION
4 July 2018
Marine and coastal ecosystems are among the largest contributors to the Earth's overall productivity, i.e. the generation of biological living organisms, or biomass. These areas are also contaminated by microplastics worldwide. Do microplastics in the marine environment affect marine ecosystem productivity? This is a burning question in the minds of those following the growth of plastic pollution emissions to the seas and oceans of the world. A Deltares-VU Environment & Health collaboration set out to explore this question in the case of the North Sea ecosystem. The publication can be downloaded for free (until 18 August 2018) via this share link.
CAPTAIN CHARLES MOORE VISITS E&H LAB TO TALK PLASTIC
29 June 2018

E&H SCIENTIST SPEAKS AT ECHA
30 May 2018
E&H’s microplastics expert Dr. Heather Leslie was an invited plenary speaker and break-out session participant at the European Chemicals Agency’s (ECHA).Stakeholder workshop on intentional uses of microplastic particles, held in Helsinki 30-31 May 2018. Invited participants from industry, stakeholder organisations, research institutions, the European Commission, Member State Competent Authorities and ECHA were in attendance, with an additional 200 participants following the plenary session via web-streaming. As well as touching on the current state of knowledge of the fate, exposure and potential effects of microplastics in the environment and in us, she raised the question whether or not our contemporary plastic applications are congruent with our best science, and with the moral and economic imperatives of environmental and human health protection. REACH legislation is responsible for restricting substances that pose a risk to the environment or health. At the request of the European Commission, ECHA is currently assessing the scientific evidence for taking regulatory action at the EU level on microplastics intentionally-added to products of any kind.
FRACTIONATION FOR HIGH THROUGHPUT EDA
23 April 2018
FractioMate TMWithin the STW-funded project (2012-2017) ‘High throughput Effect-Directed Analysis: a novel platform for rapid and sensitive identification of toxic compounds in the aquatic environment’, the VU and Spark Holland developed a small-volume fractionation device to speed up the typical EDA workflow. The FractioMateTM is a contact-free high frequency droplet ejection spotter device for HT-EDA. It is the bridging unit integrating biological toxicity responses with chemical data, such as mass spectrometry. The unit is placed directly post-column after chromatographic separation thereby allowing high resolution fractionation of an environmental extract, while at the same time via a split chemical data such as mass spectrometric data is acquired.

E&H messages to European Parliament: EU Action to Combat Marine Litter Workshop
E&H’s Dr. Heather Leslie made her third trip to the European Parliament in Brussels, where she has been disseminating the results of plastic waste and marine litter research and scientific insights into to the issue of marine litter and plastic waste and the policies that address these issues. This time she was an invited speaker at the EU Action to Combat Marine Litter Workshop. The meeting was chaired by MEP Simona Bonafè of the European Parliament Committee ENVI (Environment Public Health and Food Safety). Several points were made by Dr. Leslie (see also here) including that Europe urgently needs to elucidate the human health impacts of not only the chemicals in plastics but also the plastic particulates being emitted from plastic products, as this could represent a significant impact in addition to environmental and economic impacts. Drawing on the conclusions of the CleanSea FP7 Project, she called for strong leadership from European policy makers, comprehensive redesign of polluting products, and political engagement of citizens across Europe.

Synthetic microfibers in washing machines in the news
16 May 2017
E&H researchers Heather Leslie and Dick Vethaak weighed in on some current end-of-pipe solutions to keep synthetic textile microfibers out of wastewater streams. These microfibers are persistent plastic particulates that do not degrade in the environment. They are present not only in wastewater but throughout the indoor and outdoor environment and food systems, as previous E&H studies have shown. Quoted in the Dutch daily newspaper, Trouw, Leslie and Vethaak make the case that especially the very fine microfibers are environmental pollutants that may pose risks to public health. It is laudable that people are searching for ways to reduce the enormous volume of global microfiber emissions at the washing machine stage. However, because 5 billion people do not have access to washing machines currently, approaches need to be sought also in the design phase, if we are to significantly prevent synthetic microfiber emissions and exposure worldwide.

Jacob de Boer quoted in Dutch newspaper AD and interviewed on tv about GenX
15 April 2017
The Chemours chemical plant in Dordrecht should stop pumping a chemical called GenX into the Merwede river because of risk to the drinking water, the infrastructure ministry and water board officials say. GenX is used to make teflon and replaces C8 (PFOA), which is a cancer-causing chemical. Professor Jacob de Boer says GenX is also toxic and should be banned as soon as possible. De Boer was also interviewed by the Ducth news programme 'EenVandaag'.
Microplastic contamination widespread throughout Dutch marine and freshwater systems
21 February 2017
These findings are described in a new publication by E&H researchers in collaboration with Prof. Dick Vethaak of both the VU-E&H and Deltares. The diverse dataset shows that plastic pollution is found at significant concentrations in major Dutch rivers, treated wastewater effluents, Amsterdam canals, several coastal marine species, as well as in estuarine and marine sediments off the Dutch coast. The environmental monitoring of plastic concentrations is a key aspect in the process of pollution mitigation, and this study provides the best baseline available to date for microplastic pollution in the Netherlands.

Lack of sleep may lead to consumption of more calories
3 November 2016
A broad-based meta-study, in which nutritionist Gerda Pot participated, shows that people may consume more calories the day after experiencing lack of sleep. Her study combines results from numerous smaller intervention studies to obtain stronger evidence about the consequences of lack of sleep. Her meta-study shows that people eat an average of 385 kcal more the day after experiencing lack of sleep than people who have had sufficient sleep, equivalent to about 4.5 slices of bread. The researchers published their article in the European Journal of Clinical Nutrition. The New York Times published a news article about this study.
Banned chemical substances survive after recycling
29 October 2016
Environment and Health researchers were commissioned by the Ministry of Infrastructure and the Environment to determine the amount of banned flame retardant in plastic waste streams. It turns out to be a lot. Heather Leslie: ‘We examined products in the plastic waste streams in the Netherlands which we knew to have contained brominated flame retardants, such as electronic waste and old car parts. Our analysis showed that in 2013, 7.2 tonnes of banned brominated flame retardant came back into circulation through reuse and recycling.’
Prof. Jacob de Boer about GenX on RAI Uno
24 October 2016
Prof. Jacob de Boer was interviewed briefly about GenX in a programme on RAI Uno. This chemical has been used by Chemours chemical company in Dordrecht since 2012 to make Teflon, a material which is used in non-stick surfaces for example. Chemours markets Genx as a safe alternative to perfluorooctane acid (PFOA), which is carcinogenic. De Boer explained in the programme that Genx does not remain in the body as long as PFOA (the body eliminates the substance within a few days); however, it does dissolve more easily in water. That makes it more likely to enter the water supply than PFOA. Since the substance is persistent and does not decompose easily, toxicologists expect it to start accumulating in drinking water within a few years. Watch the broadcast (starts at 45 min. 50 secs.).
Teflon plant Chemours is is emitting cancer-causing chemicals
20 July 2016
Dordrecht teflon plant Chemours (formally DuPont) is emitting a cancer-causing chemical into the atmosphere which endangers the health of workers and locals, the Volkskrant said on Wednesday. The substance, known as GenX, has been shown to cause cancer, liver and kidney disease and fertility issues in mice and rats, the paper said. Toxicologists are now calling on Chemours to stop emissions of GenX via the plant chimneys. ‘You cannot just spread this sort of poison in residential areas,’ toxicology professor Jacob de Boer told the paper (source: www.dutchnews.nl).

Professor Jacob de Boer interviewed on TV about poisonous fish
28 June 2016
Around fifty people die each year from what is known as ciguatera: a disease contracted by eating fish containing the poison ciguatoxin. This poison is found in algae and tropical fish such as barracuda and bass, which eat other fish that have consumed the algae, thus storing the poison in their body. Algae containing the poison mostly grow in the Caribbean. The risk of poisoned fish entering the Dutch market is miniscule. ‘Because inspection is so thorough here’, toxicologist Jacob de Boer explains. But he advises anyone holidaying in the Caribbean to be cautious.
Late evening meals do not cause children to gain weight
17 May 2016
Eating meals after eight in the evening does not cause children in England to gain weight. That is the conclusion of a King’s College London study led by nutritionist Dr Gerda Pot, currently working at VU University Amsterdam and King’s College London. Her findings contradict previous research which suggested a possible link between eating late in the evening and an increased risk of obesity and metabolic disorder. The study was published in the British Journal of Nutrition.
