Litho- and biostratigraphical study of Quaternary deep marine deposits of the western Belgian coastal plain

Elaborate deep borings for hydrogeological purposes in the western part of the Belgian coastal plain revealed the presence of deep marine sediments with different facies. A combined diatom-, mollusc- and pollen investigation procurred many new and interesting data about the diatom flora and the mollusc fauna as well as about the environment and the age of the sediments. The absence of direct reference investigations preventing uniform conclusions at this stage of the investigations. A radio-carbondating and the pollen analysis showed the presence of boreal sediments at the same depth of probably older (Eemian) deposits

Have international pollution protocols made a difference?

Evaluating the effectiveness of international agreements is inherently difficult due to problems such as self-selection, spillovers, anticipation effects, and aggregate-level data. In this paper, I provide new and arguably more credible estimates on the effects of three major pollution protocols on SO2, NOx, and VOC emissions. I do so by combining a newly available global dataset on emissions dating back to 1970 with a generalized version of the synthetic control method. By constructing “synthetic” controls that mimic the pre-treatment development of each affected country, I mitigate bias caused by self-selection and non-parallel emission trends. The broader data coverage - both geographically and over time - allows me to examine the importance of spillovers and anticipation effects. Results from the estimation show that all three protocols induced emissions reductions well beyond a (synthetic) counterfactual development

The impact of European legislative and technology measures to reduce air pollutants on air quality, human health and climate

European air quality legislation has reduced emissions of air pollutants across Europe since the 1970s, affecting air quality, human health and regional climate. We used a coupled composition-climate model to simulate the impacts of European air quality legislation and technology measures implemented between 1970 and 2010. We contrast simulations using two emission scenarios; one with actual emissions in 2010 and the other with emissions that would have occurred in 2010 in the absence of technological improvements and end-of-pipe treatment measures in the energy, industrial and road transport sectors. European emissions of sulphur dioxide, black carbon (BC) and organic carbon in 2010 are 53%, 59% and 32% lower respectively compared to emissions that would have occurred in 2010 in the absence of legislative and technology measures. These emission reductions decreased simulated European annual mean concentrations of fine particulate matter(PM2.5) by 35%, sulphate by 44%, BC by 56% and particulate organic matter by 23%. The reduction in PM2.5 concentrations is calculated to have prevented 80 000 (37 000–116 000, at 95% confidence intervals) premature deaths annually across the European Union, resulting in a perceived financial benefit to society of US$232 billion annually (1.4% of 2010 EU GDP). The reduction in aerosol concentrations due to legislative and technology measures caused a positive change in the aerosol radiative effect at the top of atmosphere, reduced atmospheric absorption and also increased the amount of solar radiation incident at the surface over Europe. We used an energy budget approximation to estimate that these changes in the radiative balance have increased European annual mean surface temperatures and precipitation by 0.45 ± 0.11 °C and by 13 ± 0.8 mm yr−1 respectively. Our results show that the implementation of European legislation and technological improvements to reduce the emission of air pollutants has improved air quality and human health over Europe, as well as having an unintended impact on the regional radiative balance and climate

The 1979 Convention on Long-Range Transboundary Air Pollution: Assessing its Effectiveness as a Multilateral Environmental Regime after 35 Years

There is no definitive approach to assessing the effectiveness of international environmental regimes. In order to explore the regime established by the 1979 Geneva Convention on Long-Range Transboundary Air Pollution this article broadly integrates the approach to effectiveness taken by Peter H. Sand in The Effectiveness of International Environmental Agreements, and Daniel Bodansky in The Art and Craft of International Environmental Law. The article finds that compliance, institutional, and normative effectiveness can be evaluated relatively confidently. An effectiveness assessment of the long-range transboundary air pollution (LRTAP) regime indicates that, on the whole, it has helped states to reach agreement on contentious issues and achieve results in air pollution reduction. However, it faces significant challenges with regard to participation, implementation procedures, empowerment of domestic stakeholders, and funding. The article provides an in-depth and up-to-date look at the LRTAP regime, including the most recent amendments and its relationship with European Union and international law

De verzamelwoede van Martinus van Marum (1750-1837) en de ouderdom van de aarde. Herkomst en functie van het Paleontologisch en Mineralogisch Kabinet van Teylers Museum

This study examines the provenance of the mineralogy and palaeontology collections of Teylers Museum in Haarlem. These objects, combined with the thousands of handwritten labels that have been preserved, most of which date from the 18th century, are silent witnesses to a largely forgotten world of collecting practices, classifications, academic networks, commercial practices, debates on the nature of fossils and the formation of the earth’s crust, and much more besides. My research is an attempt to reveal the world behind these objects, all of which were once collected for Teylers Museum by the first Director Martinus van Marum (1750-1837). It seeks to give the collection back its voice. Combining the financial records of the Teylers Foundation with the minutes of meetings held by the directors and Teylers’s Second Society, as well as Van Marum’s travel journals, written records of public lectures, correspondence, and other manuscripts made it possible to reconstruct his purchases and to match labels to objects. When the entirety of Van Marum’s geological endeavours is surveyed, he emerges as more of a follower of scientific developments than a knowledge producer. He published very few articles in this field, and the ideas he presented in them were seldom new and sometimes misconceived. His activities in geology were not on a par with his great achievements in physics and chemistry. However, by virtue of his positions in the Teylers Foundation and the Holland Society of Sciences, as well as his publications on plant physiology and static electricity, he was regarded as one of the most influential scientists of his day..History of Scienc

eNd Points Challenges for Science and Policy

The theme of this Second International Nitrogen Conference is “Optimising nitrogen management in food and energy production and environmental protection”. With this theme in mind and with some observations, partly made during the week of the conference, some remarks can be made that will hopefully contribute to the goal of this conference and challenge and inspire both scientists and policy makers. Although being a representative of the Dutch government, the views and ideas brought forward in this paper do not necessarily represent those of the Dutch government. Also be aware of the fact that the ideas presented here are very much the views of a policy maker from a Western developed country
