Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold , upholstered furniture , arts and crafts supplies, dry cleaned clothing, and cleaning supplies . [ 2 ]
In the US, dimethyl carbonate was exempted under the definition of volatile organic compounds (VOCs) by the U.S. EPA in 2009. [9] Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents.
The stability and lipophilicity of organic compounds often correlates with their halogen content, thus polyhalogenated organic compounds are of particular concern. [1] They exert their negative effects on the environment through two processes: long range transport, which allows them to travel far from their source, and bioaccumulation, which ...
Non-methane volatile organic compounds (NMVOCs) are a set of organic compounds that are typically photochemically reactive in the atmosphere—marked by the exclusion of methane. [1] NMVOCs include a large variety of chemically different compounds, such as benzene , ethanol , formaldehyde , cyclohexane , 1,1,1-trichloroethane and acetone . [ 2 ]

In heat vitrification, bringing the material to roughly 1850 °C has been shown to effectively immobilize heavy-metals and non-volatile inorganic compounds. [29] Electrokinetic remediation involves using electric currents to extract pollutants from the ecosystem, and is effective in the removal of radionuclides, heavy metals, and organic ...
The seventh meeting of the Persistent Organic Pollutants Review Committee (POPRC-7) of the Stockholm Convention on Persistent Organic Pollutants (POPs) took place from 10 to 14 October 2011 in Geneva. POPRC-8 was held from 15 to 19 October 2012 in Geneva, POPRC-9 to POPRC-15 were held in Rome, while POPRC-16 needed to be held online.
According to the Oxford English Dictionary, the suffix ‘omics’ refers to ‘the totality of some sort’. In biology, ‘omics’ techniques are used for the high-throughput analysis of DNA sequences and epigenetic modifications (genomics), mRNA and miRNA transcripts (transcriptomics), expressed proteins (proteomics), as well as synthesised metabolites (metabolomics) in a biological system ...
