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 ]
Houseplants together with the medium in which they are grown can reduce components of indoor air pollution, particularly volatile organic compounds (VOC) such as benzene, toluene, and xylene. Plants remove CO 2 and release oxygen and water, although the quantitative impact for house plants is small.
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 ...
In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...
Vapor intrusion (VI) is the process by which chemicals, usually volatile organic compounds (VOCs), in soil or groundwater migrate to indoor air above or around a contaminated site. [1] The process of VI has been studied more recently in relation to its effects on humans and the environment, and is becoming more regulated by the United States ...
A pollutant or novel entity [1] is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts).
Volatile organic compounds (VOCs) are released from many household cleaning products such as disinfectants, polishes, floor waxes, air-freshening sprays, all-purpose cleaning sprays, and glass cleaner. These products have been shown to emit irritating vapors.
Organic matter (OM) found in aerosols can be either primary or secondary, the latter part deriving from the oxidation of volatile organic compounds (VOCs); organic material in the atmosphere may either be biogenic or anthropogenic. Organic matter influences the atmospheric radiation field by both scattering and
