Marine microplastic (,5 mm) water pollution has met growing public and scientific interest in the last few years. The situation in freshwater environments remains largely unknown, although it appears that they play an important role as part of the origin o ...
A laboratory experiment and numerical modeling were used to examine effects of density gradients on hyporheic flow and solute transport under the condition of a solute pulse input to a river with regular bed forms. Relatively low-density gradients due to a ...
Microplastics in freshwater are becoming of emerging concerns. In Switzerland, some recent studies reveals the microplastics pollution of Swiss lakes and rivers. The aim of the present study is to improve the understanding of the origins of this pollution. ...
Marine microplastic (< 5 mm) water pollution has met growing public and scientific interest in the last years. The situation in freshwater environments remains largely unknown, although they appear to play an important role as part of the origin of marine ...
This project is set in a context of raising awareness concerning the accumulation of plastics in oceans. As opposed to the marine environment, there is a real gap of knowledge on microplastics pollution in freshwaters. In this project, the Lake Geneva envi ...
Forest decline played a pivotal role in motivating Europe's political focus on sustainability around 35 years ago. Silver fir (Abies alba) exhibited a particularly severe dieback in the mid-1970s, but disentangling biotic from abiotic drivers remained chal ...
Mobile Wireless Sensor Networks (WSNs) hold the potential to constitute a real game changer for our understanding of urban air pollution, through a significant augmentation of spatial resolution in measurement. However, temporal drift, crosssensitivity and ...
Numerous researches showing various environmental impacts are done on marine plastic pollution. In turn the situation for superficial fresh water is poorly known. In order to measure this pollution in Switzerland three different lake samples (lake Geneva, ...
The effects of the human convective boundary layer (CBL), room airflow patterns, and their velocities on personal exposure are examined. Two pollutants are studied which simulate particles released from the feet and generated at distances of 2 and 3 m by a ...
“Well-mixed” assumption often leads to inadequate prediction of the human exposure. In spaces that operate with a low air velocity, local airflows generated by occupants play predominant role for pollutant transport. The present study investigates the abil ...
