Global climate change (GCC) is likely to alter the degree of human exposure to pollutants and the response of human populations to these exposures, meaning that risks of pollutants could change in the future. The present study, therefore, explores how GCC might affect the different steps in the pathway from a chemical source in the environment through to impacts on human health and evaluates th...

The exploitation of thermal water as a heat source in houses and apartments (during winter) is a widely used alternative to natural gas. However, this type of water may contain organic contaminants, which must be removed before releasing the used water into rivers and lakes. Because of the presence of a wide range of pollutants (including phenolic compounds and humates), efficient, cheap remova...

In this review the surface chemistry and properties of aqueous atmospheric aerosols are explored. Water plays a major role in scavenging pollutants. Reactions occur on thin water films in atmospheric aerosols. The study of the aerosol water surface is important to properly account for chemical transformations in the troposphere. The thermodynamics of adsorption of organic molecules and oxidant ...

Even small areas as Bjelovar-Bilogora County (BBC) are affected by increasing local and regional pollution. A large variety of organic compounds exists in all parts of the atmosphere, waters and soil, accumulates in living organisms and on anthropogenic objects. This work investigates organic pollutants in BBC in relation to their spread, behavior and chemical properties, based on literature da...

Chemical pollution of the environment has become a major source of concern. Studies on degradation of organic compounds have shown that some microorganisms are extremely versatile at catabolizing recalcitrant molecules. By harnessing this catabolic potential, it is possible to bioremediate some chemically contaminated environmental systems. Composting matrices and composts are rich sources of x...

background: hemodialysis is a life-saving process used as a treatment for many patients sufferimg from renal failure. because of the large amount of water used in this process, contamination of hemodialysis water with microbial and harmful chemical pollutants is possible. therefore, considering standards of dialysis water is critical. the aim of this study was to investigate the microbiological...

an improved chemical regeneration of the granular activated carbon (gac) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (caf) was investigated. in the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed gac is 103% of original gac. using oxidant and surfact...

Laccase (benzenediol : oxygen oxidoreductases; E.C. 1.10.3.2) a copper oxidase enzyme is capable of oxidizing phenolic and non-phenolic lignin related compounds as well as highly recalcitrant environmental pollutants such as aromatic amines. Their broad substrate specificity makes laccases highly suitable for diverse applications such as pulp bleaching, textile dye bleaching and bioremediation,...

There has always been a paramount concern over the widespread occurrences of various pollutant types, around the globe. With ever increasing scientific knowledge, socio-economic awareness, human health problems and ecological apprehensions, people are more concerned about the widespread environmental pollutants. Thus, the occurrences of newly identified pollutants so-called ―emerging pollutants...

The Great Lakes Water Quality Agreement commits the United States and Canada to restore and protect the chemical integrity of the Great Lakes basin. In particular, the Agreement commits to “virtually eliminate” selected persistent toxic substances. While progress has been made reducing these substances in the Great Lakes basin, other chemicals are emerging as potential pollutants in the basin. ...
