A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

Kunnen landen bij gebrek aan een sterk internationaal kader voor milieubescherming unilateraal optreden om het wereldwijde milieu te beschermen?

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

Weinig verdragen waarover door de Europese Unie wordt onderhandeld roepen zoveel weerstand op het Transatlantic Trade and Investment Partnership (TTIP). Van chloorkip tot het gebrek aan democratie en transparantie: de emoties lopen hoog op. Op 4 en 5 december vond daarom op het Leiden University College…

On 19 January (15:30-16:30), the Nicholas Brunmayr (Bruxelles) will give a talk on medieval butter trade at the Amsterdam Centre for Urban History.

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Medewerkers en studenten van het departement Archaeological Heritage and Society van de Faculteit Archeologie onderzoeken welke rol het verleden kan spelen in moderne samenlevingen. Zij willen meer weten over de relaties tussen verleden en heden, en de rol die erfgoed daarbij speelt.

Sinds 1974 wordt Wereldmilieudag elk jaar gevierd op 5 juni, waarbij regeringen, bedrijven en burgers worden betrokken bij een poging dringende milieukwesties aan te pakken.

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…
