We investigated the behavior of metallic silver nanoparticles (Ag-NP) in a pilot wastewater treatment plant (WWTP) fed with municipal wastewater. The consisted nonaerated and an aerated tank secondary clarifier. average hydraulic retention time including clarifier was 1 day sludge age 14 days. Ag-NP were spiked into samples collected from effluent. Ag concentrations determined by inductively coupled plasma-mass spectrometry (ICP-MS) good agreement predictions based on mass balance...
Urban water management requires further clarification about pollutants in storm water. Little is known the release of organic additives used construction materials and impact these compounds to runoff. We investigated sources pathways materials, i.e., biocides facades' render as well root protection products bitumen membranes for rooftops. Under wet-weather conditions, concentrations diuron, terbutryn, carbendazim, irgarol®1051 (all from facades) mecoprop receiving exceeded predicted...
This paper was motivated by a recent article in which the levels of electromagnetic energy absorbed heads mobile phone users were compared for children and adults at frequencies 835 MHz 1,900 MHz. Significant differences found, particular substantially greater absorption children's These findings contradict other studies no significant changes had been postulated. The clarification this issue is crucial to communications industry since current SAR evaluations as required FCC are only...
ABSTRACT Despite their common use in animal production the environmental fate of veterinary sulfonamide antibiotics after excretion is only poorly understood. We performed irrigation experiments to investigate transport these substances with surface runoff on grassland. Liquid manure from pigs treated sulfadimidine was spiked sulfadiazine, sulfathiazole, herbicide atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐1,3,5‐triazine), and conservative tracer bromide spread onto eight plots. Four...
The European Biocidal Products Directive 98/8/EC requires a risk assessment concerning possible effects of active ingredients on the environment. Biocides can be leached from treated materials exposed to outdoor use. These emissions have estimated and evaluated during authorization procedure. Different immersion irrigation tests were performed investigate leaching biocides façade coatings. Several marketed formulations textured coatings paints spiked with mixture commonly used (OIT, DCOIT,...
Biocides are included in organic building façade coatings as protection against biological attack by algae and fungi but have the potential to enter environment via leaching into runoff from wind driven rain. The following field study correlates rain measured release of several commonly used biocides (terbutryn, Irgarol 1051, diuron, isoproturon, OIT, DCOIT) four coating systems. During one year exposure a west oriented model house Zurich, Switzerland area, an average 62.7 L/m2, or 6.3%...
There is increasing concern about diffuse pollution of aquatic systems by biocides used in urban areas. We investigated sources and pathways significant for the storm water runoff. Main seem to be building envelopes, i.e. facades (paints, plasters) roof sealing membranes. First results from a defined catchment drained separated sewer system without any agricultural activities reveal substantial occurrence. Even after first flush, concentrations terbutryn, carbendazim, mecoprop as well...
A large variety of substances are used in building materials to improve their properties. In recent years, attention organic additives used, for example, renders, façade paints or roof sealing sheets has increased as these compounds have been detected urban stormwater runoff and surface waters. this paper, we show the extent emissions induced by rain events two study sites Berlin. For purpose, from roofs, façades, storm sewers was sampled analysed over a period 1.5 years residential...
Crawford TEM cells are often used to expose cell cultures or small animals in order study the effects caused by high-frequency fields. They self-contained, easy-to-use setups that provide a rather homogeneous field distribution large area around its center, corresponding approximately far-field conditions. However, number of conditions must be met if such intended for vitro experiments. For instance, poor interaction with incident maintained avoid significant disturbances cell. This is best...
