Digital Photographic Technique to Quantify Plume Opacity During Daytime and Nighttimebient air. Method 9 is USEPA’s standard method to quantify plume opacity by visual observations from qualified human observers during daytime. These observers are required to be certified twice a year at a “smoke school”. “Smoke school” is more formally referred to as “Visible Emissions Training”, w

Scanning Infrared Remote Sensing System for Detection, Identification and Visualization of Airborne n studies done by the Department of Safety Engineering/Environmental Protection at the University of Wuppertal a passive FT/IR was used to show the possibilities of such a system. The fast identification of accidentally released substances is a very important hint in finding leaks and stopping the r

Aerosol Concentrations and Remote Sources of Airborne Elements Over Pico Mountain, Azores, PortugalThe aethalometer is at an altitude of 2225 m AMSL, and sampled for 24 h in most cases, and for a few periods continuously. Samples were assessed through instrumental neutron activation analysis (. .-variant), and concentrations of up to 15 airborne elements were determined. Concentrations are in the

Removal of Selected Organic Micropollutants from WWTP Effluent with Powdered Activated Carbon and Reld. In order to preserve fresh water resources waste water reclamation can serve as a promising but technically challenging alternative to conventional water sources. Besides pathogens, organic trace pollutants cause major concerns in reclamation schemes. In this project, the removal of four micropo

Development of Vertically Moving AutomaticWater Monitoring System (VeMAS) for LakeWater Quality Manaological transformations of water quality constituents, proper water management of lakes and reservoirs would not be possible. In general, in-lake water quality related data are less abundant compared to data for rivers. This is especially true for vertical profile data for lake stratification. An i

Toxicity of Metallic Nanoparticles in Microorganisms- a Reviewntal health. NPs are highly reactive and catalytic in nature compared to their ions or bulk counterparts and thus applicable in various fields including drug delivery, electronics, optics, and therapeutics. Due to these applications, many varieties of NPs in massive amounts are being industrially pr
