The estrogen receptor protein (ER) can bind a vast number of organic pollutants widely spread in the environment and collectively known as Endocrine Disrupting Chemicals, EDCs. Its broad selectivity makes it an ideal bio-recognition element for the detection of EDCs. Here we describe the strategy and rationale for the design of ER based biosensors and assays that generate a signal in the presen...

Microbial reactions play key roles in biocatalysis and biodegradation. The recent genome sequencing of environmentally relevant bacteria has revealed previously unsuspected metabolic potential that could be exploited for useful purposes. For example, oxygenases and other biodegradative enzymes are benign catalysts that can be used for the production of industrially useful compounds. In conjunct...

This paper presents a new method for realistic real-time rendering of air pollutants based on image processing. The air pollutants’ variable density can create many shapes of mist what can add a realistic environment to virtual scene. In order to achieve a realistic effect, we further enhance thus obtained air pollution data getting from monitor in spatial domain. In the proposed method we map ...

Snowmelt is known to cause peak concentrations of pollutants, which may adversely affect receiving water quality. High concentrations of metals and suspended solids in snow have been reported, whereas studies on organic pollutants are rare. This study aims at investigating the occurrence of anthropogenic organic compounds in urban snow in Gothenburg (Sweden). The most frequently detected organi...

The 1990 Clean Air Act Amendment (CAAA) empowered the U.S. Environmental Protection Agency (EPA) to set emission standards for a number of potentially hazardous air pollutants (HAPS) generated by a variety of specific combustion sources. Eleven elements (or compounds of these elements) present in coal are among the 189 pollutants identified as air toxics by the CAAA legislation. Mercury is incl...

In this article, we present an overview on the role of marine pollutants in impairment of DNA integrity in marine gastropods exposed to xenobiotics released from various sources into the coastal ecosystem. We provide an insight into the impact of various types of genotoxic compounds on the physiologic status of marine organisms, with specific focus on DNA integrity. DNA damage in marine gastrop...

Phytoremediation use plants to remove pollutants from the environment and render them harmless. It is an economically feasible and sustainable ways regarding to the remediation of our environment without introducing any new contaminants. Considering the vast diversity of pollutants and the different kinds of environmental conditions are two most important aspects that plants used for the remedi...

The cases of environmental contamination and toxicity originated from liquid pollutants are increasing from time to time. A fast and accurate technique is needed to study the physicochemical properties of respective liquid pollutants. Reversed-flow gas chromatography, which is a sub-technique of inverse gas chromatography, is an experimental arrangement simulating a simple model for the action ...

Overproduction of reactive oxygen and nitrogen species can result from exposure to environmental pollutants, such as ionising and nonionising radiation, ultraviolet radiation, elevated concentrations of ozone, nitrogen oxides, sulphur dioxide, cigarette smoke, asbestos, particulate matter, pesticides, dioxins and furans, polycyclic aromatic hydrocarbons, and many other compounds present in the ...
