PM 2.5 samples were collected from the exhaust stacks on the roofs of a university canteen, a charcoal-grilled chicken restaurant and a wood-oven roasted piglet restaurant. The use of thick exhaust hood filters and also gas and electricity as energy sources for cooking in the kitchen of the...

The Douro River lower basin water quality was studied regarding its concentration on 18 trace elements (Be, Al, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sb, Ba, Tl, Pb and U, measured by ICP-MS). Other physicochemical parameters, such as pH, conductivity, dissolved oxygen and water temperature...

We have carried out a geochemical study on the behaviour of certain trace elements during the evaporative concentration of free brines (salinity from 41 to 400 ‰) of the solar salt works of Sfax saline (S.E of Tunisia). The elements concerned by this survey are Zinc, Cadmium, Manganese, Molybdenum...

The commonly accepted brine concentration practice in most Chinese Northern solar works is to pump the sea water into salt works and then let it go through a physical changing process of natural evaporation, condensation and crystallization, during which, weather factor and the soil nature have to...

The trace element analysis of Aleppo pine (Pinus halepensis Mill) as a function of tree age, was achieved by the tree-ring sampling method, in a polluted region of Attica, Greece. The elements quantitatively determined for the last 140 years by atomic spectrophotometry analysis were: Cu, Fe, Zn, Mn...

The effects of effluent from Thessaloniki, the second most populated Greek city, reclaimed either by activated sludge or by stabilization ponds, were studied on field-grown corn. The experimental layout was that of a split- plot design with six replications, three water qualities and two irrigation...

A main problem related to coal ash disposal is the heavy metal content of the residue. In this regard, experimental results of numerous studies have indicated that toxic trace metals may leach when fly ash and bottom ash contacts with water. In this study, fly ash and bottom ash samples obtained...

Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...

Arsenic is an ubiquitous and highly toxic metalloid widely distributed in the environment through both natural and anthropogenic pathways (Liu et al., 2004) and its presence in food composites is a matter of concerns to the well being of both humans and animals. In fact, As has been recently found...

Particulate matter measurements were performed at the Akrotiri research station on the island of Crete (Greece) using an 8-stages Andersen non-viable impactor. The main purpose of the current work was to measure the ambient levels of PM10 particulate matter as well as the concentrations of metals...

The aim of the present work was to characterize particulate matter (PM) and elemental carbon (EC) indoor and outdoor concentration levels in the Athens area and to examine the contribution of ambient air to the observed indoor levels. 24-hr simultaneous indoor and outdoor PM10 and PM2.5 measurements...

The main issue discussed in the paper is the application of qualitative analysis techniques when short data samples are available at the initial stage of experiments carried out to study behaviors of agricultural plant species under different environmental conditions. The proposed techniques are...

The Mn and Pb of the total suspended particulates (TSP) in totally 95 1-h samples and As, Cd, Mn, Ni and Pb in totally 29 24-h samples have been determined by flameless graphite furnace atomic absorption spectrophotometry. The monthly TSP for July 1992 contained Mn and Pb 0.033 and 1.25‰ in downtown...

More than 73% of the electrical power requirements of Greece are generated in lignite-fired power plants. Greece is the thirteenth largest coal and the fifth largest lignite producer in the world. The lack of domestic high-rank coals makes necessary to use low quality lignite for power generation in...

Coals contain elements which, although usually found in concentrations lower than 1% (trace elements), can give rise to environmental or technological problems. After gasification most of these elements may occur in gas phase in different proportions. In order to avoid the problems that the presence...

In coastal marine environments, with shallow, warm and calm waters, it is sometimes possible to observe the presence of organosedimentary structures that are commonly flat and laminar in shape. These structures are called algal mats or recent stromatolites due to their remarkable similarities to...

Metal pollution can have adverse effects on human health but also on environment. Usually, risk is assessed on the basis of the total concentration of a trace metal in soils and sediments. Nevertheless, for checking the short and long-term true environmental impact of a trace element, one of the...
