Heavy metals and trace elements are ubiquitous throughout the environment, some are essential for life (e.g., Fe), others are micronutrients (e.g., Se) and others are considered as toxic elements (e.g., Hg). Levels of these elements in the environment are determined by the local geochemistry and anthropogenic emissions, with implications for human and environmental health. Records from Alpine ice...
Atmospheric mercury depositions have increased approximately by a factor of three since industrialization, which also led to increase of methylmercury (MeHg) levels in fish, spawning a large number of health advisories. Mercury is now the most common contaminant responsible for fish consumption advisories in the United States and Canada. Almost all US states have regulations against fish consumption...
Industrial, agricultural and other anthropogenic activities have lead to the introduction of thousands of pollutants, most of them synthetic organic compounds to the marine environment (Dachs and Méjanelle 2010). A fraction of these organic compounds, called persistent organic pollutants (POPs), are chemicals that have become a major concern because of their toxicity, persistence, bioaccumulation...
The discovery of the insecticidal properties of DDT by Paul Müller (Läuger et al. 1944; DDT was synthesized more than 50 years ago (Zeidler 1874) can be deemed as one of the starting points of intensive search of organic compounds to be used as pesticides. These organic compounds were – and are – used and applied deliberately especially in the environment due to their properties as poisons against...
Volatile organic compounds (VOCs) are normally present in the vapor phase at room temperature (vapor pressure greater than 0.1 mmHg [0.0133 kPa] at 25°C). Compounds less volatile are known as semi-volatile organic compounds (SVOCs). SVOCs may be present in the atmosphere in the vapor phase, but are more normally associated with aerosol, either as dusts or liquid droplets (Lodge 1991; Kouimtzis and...
Per- and polyfluorinated compounds (PFCs) comprise a large group of chemicals, consisting of a hydrophobic alkyl chain and usually possessing a hydrophilic functional group. The alkyl chain is partly or fully fluorinated and typically contains between 4 and 18 carbon atoms (De Voogt and Saez 2006). Therefore, PFCs are both oleophobic and hydrophobic and form strong surfactants. PFCs comprise ionic...
