Through transportation accidents or intentional releases, plastic pellets (small granules 1-5 mm in diameter) are widely distributed in the ocean all over the world. These pellets accumulate organic pollutants and can be used for the determination of diffusive seawater pollution. Pellets...

The present study deals with the problem of soil contamination risk assessment for a region being actively impact by the routine production of Kremikovtzi metallurgical plant near Sofia, Bulgaria. Although the production is now cancelled, the soil pollution is present and needs careful assessment...

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...

Anionic poly(sodium acrylate), PANa, hydrogels bearing negatively charged –COO- groups were used as sorbents for the removal of colored organic or inorganic model pollutants, namely Crystal Violet and Cu2+, from water. It was found that PANa hydrogels adsorb stronger Cu2+ions than Crystal Violet, as...

Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO2, NO, and NO2 from “sweet” natural gas while “sour” gas emits SO2 in addition; incomplete combustion...

The work deals with coal combustion in a pilot-plant fluidised bed (7 cm i.d.) under atmospheric conditions. The aims are to capture and analyse qualitatively as well as quantitatively the volatile polycyclic hydrocarbons emitted by using coal as energy source under various combustion conditions...

Pollutants posing health risks to human health and to the aquatic environment often occur in drinking and surface waters, as a result of disinfection practices, agricultural and industrial activities, wastewater discharges. Toxic pollutants belong to different chemical categories, including...

Activated carbon (AC) amendment for reduction of contaminant exposure in polluted soils and sediments has recently emerged as a promising remediation technique. Here, we provide a short overview of the state-of-the-art in activated carbon (AC) amendment to such sites. Most studies not only in...

In 2006, California passed legislation establishing the first State Biomonitoring Program in the USA. The main goals are to: 1) Determine levels of environmental chemical contaminants in a representative sample of Californians; 2) Establish trends in the levels of these chemicals over time; 3)...

Industrial facilities emit pollutant air that contains volatile organic compounds (VOCs) and reduced sulphur compounds (RSCs) which are nuisance, corrosive to materials and dangerous to health. In recent years, biofiltration has replaced numerous conventional processes (i.e. adsorption) due to its...

Results of a monitoring project for the water quality of three important rivers of western Greece (Acheloos, Louros and Acherontas) are presented in this paper. The results include the concentrations as well as the temporal and spatial distributions of nitrates, nitrites, phosphates, ammonia and...

The unintended release of hydrocarbons into the environment can negatively impact human and animal health, and could further change the characteristics of soils. The aim of the present work was to investigate the rate of biodegradation at 10 and 20% diesel fuel in contaminated soil amended with 10%...
