Yesterday, an article appeared in Biznews about the watershortages in California. David Zetland, university lecturer at Leiden University College, gives his opinion about this problem.

Description of Biotic ligand models: making an inventory of available models & assessment of the variability of the predicted HC5 using the BLMs in different Dutch water types (2005 - 2007)

Description of Atlas of the surfacewater concentrations of pesticides in the Netherlands, a pilotstudy.

Fate and toxicity of copper nanoparticles was related to the water chemistry of the environment and pristine size.

What is the effect of pesticides, fertilizers or plastic on water quality? And how do wind and rain affect the data? These are just some of the things that Leiden environmental scientists study in the 32 ditches of the Living Lab.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

Exploring linkages between energy and material use and implications for sustainable development.

Description of Development of a low cost technology for in-situ treatment of groundwater for potable and irrigation purposes (TiPOT) (2004 - 2007)

Biodiversity in the Netherlands is having a tough time. Professor of Natural Capital Koos Biesmeijer combines research with practical advice: from the greening of industrial parks to solutions inspired by hi-tech nature. Inaugural lecture 9 March.

The walking club is a ProParte sub-group.

You pour a scoop of ditch water in the DNA scanner, and voilà: you know exactly which plants and animals the ditch accommodates. Well, it is not that simple yet, but according to PhD candidate Kevin Beentjes, we can already use DNA techniques to monitor the quality of freshwater. For his PhD research,…

From junior school pupils to university students: the Living Lab is a valuable place of study for many people. Every year the Living Lab trains dozens of students at vocational, college and university level. More than a thousand pupils also have lessons on location, and junior schools use over thirty…

Ecotox is a stimulating top-facility that provides an integrative research environment around the topic of ecotoxicological testing and experimental research. Research focus: Dose-response modelling Mode-of-actions and mechanism-of-actions Test method development, in view of targets in AOPs (adverse…

The plans for making the University Library (UB) more sustainable will be carried out in three steps: first the glazing at the front of the building will be replaced with HR++ glass, then the skylights will be renewed and finally the air conditioning system will be updated. Once these steps have been…

- Which metabolites could be components of NADES? - How can we prove the presence of NADES in nature? - What are the roles of NADES in nature? - How to apply NADES in life sciences?

The project’s overall goal is to improve Indonesia’s environmental legal framework and its implementation by strengthening the regulatory capacity of the government, and by enhancing the capacity of CSOs and scholars to hold the government accountable for its regulatory performance.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

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.

Multicopper oxidase, laccase, can efficiently reduce oxygen to water and are mostly used in the enzymatic biofuel cells.

On 17 October 2019, Laure d'Hondt defended her thesis 'Addressing Industrial Pollution in Indonesia. The Nexus between Regulation and Redress seeking'. The doctoral research was supervised by prof. A.W. Bedner and dr. J.A.C. Vel.

Leiden University and the Ministry of Infrastructure and Water Management are involved in a collaboration in the form of a research project titled 'Data-Driven Risk Assessment in Infrastructure Networks'.

We have facilities for various research animals, all of which naturally comply with legal requirements. We take great care of the animals, and our enclosures are designed to meet the specific needs of the different species.

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

It is mostly rainfall and soil acidity that determine which microbes survive in a particular habitat and which do not. This knowledge is important for maintaining biodiversity. Leiden environmentalists contributed to the research. Publication in Nature on 1 August.

Urban, Food, Water, Biodiversity, Resources and Energy: these are the main research topics of the Institute of Environmental Sciences. We always strive to be a global leader in our field. And make a real impact with both our research programmes.

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

How to bring together different footprints into an integrated family and what are the synergies? What are the roles of inventory analysis and characterization in measuring individual footprints and how these affect a footprint family? How to benchmark environmental footprints against related planetary…

Industrialised countries extract natural resources in the territories of indigenous peoples, and appropriate the knowledge and culture of these peoples. Leiden anthropologists work to protect the rights of indigenous peoples. Their knowledge and advice enable governments to source sustainable produc…

Sustainably produced food reduces CO2 emissions during production and promotes the region’s economy. The University is working to increase the number of organic, fair trade, vegetarian and vegan products in its restaurants.

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

The Grachtwacht (Canal Watch) conducts research on urban wildlife and the impact of plastic on nature. With our clean-ups, we not only collect waste, but also data. This way we try to find out the source of the waste and turn off the tap on shore. This way there is structurally less plastic in the c…
