Microplastics are small pieces of plastic found in the environment. At CML research have been conducted in the distribution of these plastics on beaches around the world using citizen science. In addition, CML is conducting in depth case-studies in the Caribbean and along the Dutch coast. Follow-up…

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

You can't see them with the naked eye, but they are highly likely to pose a threat to our health: microplastics. These tiny plastic particles are present everywhere in the environment, including within our bodies. On science platform The Conversation molecular biologist Meiru Wang offers valuable insights…

Lecture, NGL lecture

Thijs Bosker, Associate Professor of Environmental Sciences at Leiden University College (LUC) and the Institute of Environmental Sciences (CML), has received funding as part of a large consortium to study the impacts of microplastics on agricultural soils. The project will receive 7 million euro of…

Microplastics are everywhere: in the ocean, in cooking salt and even in animals. Should that worry us? 'Yes,' said environmental scientist Thijs Bosker during a pop-up lecture in The Hague on 8 September. ‘We really need to do something now, not wait until it becomes an even bigger problem.’

Gayathri Jaikamur has been awarded by the Dopper Foundation in the Change Make Challenge. She is a student of Masters Biology (Specialisation: Evolution, Conservation and Biodiversity) from India - working under the supervision of CML-researcher Dr. Thijs Bosker (and co-supervision of Dr. Nadja Brun).…

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

The sand on European beaches may look pristine, but in every kilogram of sand there are on average 250 microplastics: fragments smaller than 5mm. These results are part of a study from Leiden researchers with the help of beach-goers throughout Europe.

Dr. Jessica Kiefte-de Jong and Dr. Thijs Bosker, both Assistant Professors at LUC, have been awarded by The Leiden University Fund (LUF).

On Friday morning, 8 June, Thijs Bosker, Associate Professor at Leiden University College, was interviewed by NPO Radio 1 on plastic pollution in Antartctica: ''Anually, an additional 4 - 12 billion kilos of plastic ends up in our ocean''.

In 2017, In 2017 we published over 70 papers, appointed two new professors, researched microplastic contamination in European beach sediment and modelled future energy demand. We awarded six PhDs and taught students from all over the world how to contribute to sustainability. We wish you a pleasant…

A team of students from Leiden and Groningen took the second prize at the European final of the BISC-E sustainability competition. Last June, the team had already won the Dutch finals. The students came up with ‘Suckerspheres’, a natural alternative to the plastic micro-particles that are still frequently…

Leiden Law Cast is a podcast made by Leiden Law School, Leiden University, for everyone who wants to learn more about current legal issues.

Four Master's students Science Communication & Society made two podcasts on the theme Plastic for the end project of their study programme. With the podcasts, they helped the Institute of Biology Leiden (IBL) to draw attention to plastic pollution. And that was harder than it seemed. 'Be sure to test…

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

Leidse milieuwetenschappers doen onderzoek naar microplastics, bestrijdingsmiddelen en bemesting. En binnenkort naar lichtvervuiling en nieuwe materialen uit de nanotechnologie.
