Perfluoro alkyl substances (PFAS) are substances in which contain multiple fluorine atoms. The fluorine atoms are bound to, often, long carbon chains. PFAS are able to repel dirt and water, due to the large amount of fluorine atoms in the molecules. PFAS are also chemically and thermally stable. Many …

Water pollution by arsenic (As) is a problem in many areas of the world for both ecology and humans. To remove arsenic from surface water an environmental-friendly method called phytoremediation could be used. This method includes the usage of plants to accumulate toxins from any environmental soil, …

This research used a newly developed, full-scale infiltration testing (FSIT) procedure to determine the saturated surface infiltration rate of 16 existing permeable pavement installations in the Netherlands that have been in service for a number of years. Newly installed permeable pavements in the Netherlands …

Electric pulse fishing is a very promising and innovative solution instead of using tickler chains such as beam trawling, to enable the catch flat fish. Bottom-trawling activities on the marine ecosystem cause the scrape of the surface or dig into the seabed. The penetration of the gears produce the …

Increasing urbanization and the effects of climate change will bring new challenges for cities, such as energy saving and supply of renewable energy, preventing urban heat islands and water retention to deal with more frequent downpours. A major urban surface, the surface of roofs, is nowadays hardly …

This paper presents a method and mock-up design for evaluating the heat-island mitigation effect of porous/water-retentive blocks in a climatic environmental chamber using ambient temperature measurements. To create the proposed method, the heat circulation mechanism of blocks was considered. From this, …

Rapid changes in the urban environment due to growth puts the urban water cycle out of balance, hence, affecting other surface and subsurface processes, such as subsidence and surface water management. Subsidence of the ground is causing risk and hazard.

Inland surface water systems are characterized by constant variations in time and space. The increased pressure, of natural or anthropic origin, as a consequence of climate change, population growth and urban development accentuate these changes. Effective water management is key to achieve European …

Siliconen, meestal dimethicone en dimethiconol, worden vaak gebruikt als conditioneringsmiddelen in shampooformuleringen. Ze zijn al effectief op zeer lage niveaus. Siliconen bezitten een reeks unieke eigenschappen zoals smerend vermogen, lage intermoleculaire krachten, onoplosbaarheid in het water …

Urban water bodies like ponds or canals are commonly assumed to provide effective cooling in hot periods. Some of the evidence that feeds this assertion is based on remote sensing observations at relatively large scales. Such observations generally reveal reduced surface temperatures of water bodies …
