We compiled published and newly-obtained data on the directly-measured atmospheric deposition of total phosphorus (TP), filtered total phosphorus (FTP), and inorganic phosphorus (PO4-P) to open land, lakes, and marine coasts. The resulting global data base includes data for c. 250 sites, covering the period 1954 to 2012. Most (82%) of the measurement locations are in Europe and North America, w...

To control deposition profile of carbon films in trenches, we have studied substrate temperature and aspect ratio dependence of deposition rate of carbon films, deposited by CVD plasma of toluene diluted H2, in trenches. The deposition rates increases with decreasing the aspect ratio, because the incident radical flux per surface area in a trench increases with decreasing the aspect ratio. The ...

A stagnation point flow (SPF) setup was used to directly observe the deposition kinetics of colloidal particles onto micropatterned glass surfaces with welldefined surface charge heterogeneity features. The SPF system consists of a microscope focused on a small collector surface area, with an automated computer controlled image-capturing device comprising a CCD camera. Surface charge heterogene...

Abstract Purpose The sediment trap method allows measurements of vertical microplastic flux rate into sediments and provides comparable information the spatial deposition rates. Such data are essential for comparison pollution rates in different sedimentary systems future risk assessments. Materials methods We monitored fluxes using traps a boreal lake seasonally during 1 year. sites represent ...

Environmental interventions are an important element of managing allergies and asthma. Health professionals often recommend that draperies be replaced with window blinds however no data exist on accumulation inhalant allergens or inflammatory bioaerosols treatments. Installing accumulate less dust may reduce breathing zone exposures when adjusted if hazardous amounts deposited. We sought to det...
