AbstractPolycyclic aromatic hydrocarbons (PAHs) are included in the European Community (EC) and in the Environmental Protection Agency (EPA) priority pollutant list due to their mutagenic and carcinogenic properties. PAHs emissions from automobile traffic and industry activities were shown to influence the PAHs levels and profiles in vegetables grown nearby. The levels of 15 PAHs were determinate in samples of pepper (Capsicum Annuum) and tomato (SolanumLlycopersicum) in different stages of plan...

Abstract Application of ozone is known to yield favorable results in purification of phosphate plant water from elemental phosphorus, in treatment of water of alkali aluminate solutions of aluminum plants, in decontamination of cyanide-containing waste water of enrichment plants, and so on. It has been proved that halogen-containing compounds, most of which have mutagenic properties, and some of which are carcinogenic to humans, are formed when water is treated with chlorine. Conclusions made...

Abstract In the study, the accumulation of secondary metabolites present in Calendula officinalis L. flowers with importance in therapeutics was examined, after the treatment with some substances considered being mutagens. The effect of substances appliedat different concentrations and different times of action was studied, qualitatively and quantitatively, considering various methanol extracts, obtained from the inflorescenses of Calendula officinalis L, which contained polyphenolic fraction...

Abstract The former Arad Chemical Fertilizer Plant had an important polluting effect on environment and, although it was shut down in 1990, its environmental heritage still exists. The paper contains a short description of the former plant and its impact on the environment, mainly on the quality of water and soil and emphasizes the effects of polluting heritage that still exists. Today, one of the major problems on the platform of the former Fertilizer Plant is the existence of all concrete b...

The most important argument of this experiment was to demonstrate an increased content of active principles under the influence of some substances (considered in the literature as mutagene), when used in low concentration, do not affect the environment. The purpose of this study was the selection of some treatment variants, which, during the experimentations show the same biosynthetic potential, stabilized or increased. The substances used in the experiment were ethidium bromide at the concentra...

The book edited by Haibo Xie and NicholasGathergood focuses on one of the most importantscientific issues of the 21 century which is thereplacing fossil fuel with sustainable alternatives suchas biomass. Fossil fuels are conventional rawmaterials for many industrial sectors includingchemical and energy production. Usage of fossil fuelis limited by their availability, price and carbonfootprint. Biomass is a renewable resource globallyavailable, cheaper and carbon sequestering. Step bystep shiftin...
