About 140 samplings of fine and coarse particles were gathered during the year 2006 in Kozani that represent an urban area surrounded by opencast coal mining. A low volume dichotomus sampler has been used to trap suspended particles. The filters used were teflon, which are ideal for analysis in the...

Abstract Spatial and temporal variation of fine particulate pollution in a complex small coastal city, Macau, was investigated by using a mobile air quality monitoring platform. Real-time street level measurements of aerosol size distribution were carried out three times per day by using an on-board...

The assessment of the air quality of indoor environment where people usually spend extended time periods, especially for sensitive population groups such as patients during their hospitalization, is of major importance. Ensuring a safe level of air quality in these indoor environment serves as an...

Attrition of limestone particles in bubbling fluidized bed has significant influence on cyclic CO 2 capture ability of sorbents. The limestone particle attrition and size distribution characteristics were investigated experimentally in a bench scale fluidized bed. The effects of initial particle...

The impacts of wind conditions to fine and coarse particle mass concentrations at four European urban centers, by multivariate regression analysis of particle measurements against categorized wind (direction and speed) conditions were estimated. Statistically significant associations (both positive...

In this study, the relationship between inhalable particulate (PM10), fine particulate (PM2.5), coarse particles (PM2.5-10) and meteorological parameters such as temperature, relative humidity, solar radiation, wind speed was statistically analyzed and modeled for the urban region of Patras during...

Enhancement of the permeate flux due to reduction of cake layer resistance by air-liquid twophase flow in a cross flow spiral wound microfiltration membrane has been investigated. Experiments were carried out with two different suspension systems, namely baker’s yeast suspension with a dry mass...

High strength geopolymers were produced from coal combustion fly ashes. These matrices reached compressive strength values over 100 MPa, much stronger and denser than obtained by using Portland Cement binders. Size fractions were obtained by size separation techniques and the relationship between...

The objective of this research is to show how sediment micro-pollution, including heavy metals, hydrocarbons and PAHs, can be reduced by means of a physical treatment based on screening and attrition. The study was carried out on five stormwater sediments, the developed pilot unit allows to isolate...

Over the last decades intensified agricultural production is applied in the northern coastal part of Korinthos Prefecture (Peloponnese, Greece). An aquifer system occurs in the recent basin deposits, which consists of unconsolidated material, namely sands, pebbles and fine clay to silty sand...

Estimates of the amount of secondary organic aerosol formed in the atmosphere from the degradation of traffic C6-C12 hydrocarbon emissions in the city of Athens are presented. Around 1.26 tn of organic aerosol is estimated to be produced during a six hours air pollution episode from the aromatic...

Two novel materials have been developed and tested in initial studies for the in-situ generation of sorption and reactive barriers for subsurface water treatment at low cost by introducing sorbents or reagents via injection wells. Both materials are based on finely-ground activated carbon with a...

Vegetation in river floodplains has significant influence on the flood hydraulics and fate of suspended sediments, nutrients and contaminants. In the present, work preliminary 3-D calculations were performed to examine the effect of vegetation on the mean flow in open channels using the CFD model...
