Polycyclic aromatics hydrocarbons are chemical species with two to six fused benzene rings and are well-known toxic hazardous pollutants and highly potent carcinogens that can cause tumors in some organisms.1 In recent years, naphthalene contamination in water systems has drawn increasing attention. Naphthalene originates from natural and anthropogenic sources. Anthropogenic sources include eng...
The aim of this study was to carry out a review of scientific literature published in Brazil between 2000 and 2009 on the characteristics of air pollutants from different emission sources, especially particulate matter (PM) and its effects on respiratory health. Using electronic databases, a systematic literature review was performed of all research related to air pollutant emissions. Publicati...
Background and purpose: Nitrate is one of the most common chemical pollutants in groundwater in the world. Adsorption has been considered as an effective and efficient method of removing pollutants, particularly nitrate from aqueous solutions and so the aim of this study was to magnetization of the carbon nanotubes with zero-valent iron and using it as an adsorbent for the removal of nitrate fr...
Background and aims Occupational diseases impose considerable burden on public health, wherein chemical pollutants in working places play an important role. One of chemical pollutants in vehicle's lock & key assembly factories is cyanoacrylate used in" loctite glue", which is assumed harmful to workers' eyes, respiratory tract and skin. This study investigates the side effects of loctite a...
Background & Objectives: Ethidium bromide is known as a Mutagenic substance that due to some of its characteristics including accumulative property in organism bodies, can cause major environmental problems. In this research, we studied the effect of activated persulfate by electrochemical method in removal of ethidium bromide in laboratory conditions. Materials & Methods: In this experimental...
To assess the overall metabolic alteration of organic pollutants through biological systems in the environment, the basic characteristics of metabolic systems in microorganisms, plants, and animals have been examined. While most of their metabolic activities contribute to reduce the levels of pollutant residues and their toxicities, certain of their activities result in the formation of stable,...
