Indoor chemistry: ozone, volatile organic compounds
, and carpets.
version of Casella's Apex Personal Sampling Pump range allows employers to undertake personal and area sampling for dusts, fumes, gases, vapours and VOC's (Volatile Organic Compounds
) in potentially explosive atmospheres.
As well as ratifying the Protocol in June 2003 (by Decision 2003/507/EC of the Council), the EU also adopted a Directive (Directive 2001/81/EC) in 2001 to introduce national emission ceilings for sulphur oxide, nitrogen oxide, volatile organic compounds
and ammonia by 2010 at the latest.
Emissions from a pulp mill contain volatile organic compounds
(VOCs) as well as malodorous mercaptanes and other organic sulfides.
Mark Smith, the company's senior staff engineer responsible for coatings, said the plant reduced volatile organic compounds
and hazardous waste by 24,000 pounds and saved $105,000 in the bargain.
While biological agents (airborne bacteria, molds, pollen, and viruses) are a major contributing factor to SBS, the other main culprits are not biological, but chemical: Formaldehyde (found in as many as 3,000 different building products, including particleboard, fiberboard, and plywood in furniture and paneling; glues; and upholstery and drapery fabrics), secondhand cigarette smoke (less prevalent since widespread bans, but still a factor), volatile organic compounds
released at room temperature as harmful gases (from some furniture, paint, adhesives, solvents, upholstery, draperies, carpet, spray cans, clothing, construction materials, cleaning compounds, deodorizers, copy machine toners, felt-tip markers/pens, and correction fluids).
The downside to reducing sulphur in the gasoline could be some increase in refinery outputs of sulphur oxides, volatile organic compounds
, and particulate matter.
to reduce costs, improve margins, and reshape [its] styrenics business." During the first phase of its new program, Nova says, it will: help customers meet environmental regulations for reduced VOCs (volatile organic compounds
) through its new VOC-Free technology and Ultra-Low Pentane EPS grades; double manufacturing capacity at its Beaver Valley, Pa., site for Arcel foam resin; increase production capacity for Dylark resin at Beaver Valley by 20 million lbs/yr; shut down the solid polystyrene (SPS) suspension reactors at its facility in Breda, The Netherlands; and shut down the SPS suspension reactors at its Chesapeake, Va., site.
To reduce evaporating emissions, foundries must examine their volatile organic compounds
(VOC) and hazardous air pollutants (HAP), particularly naphthalene emissions.
Thorsten Jurk and his colleagues presented a first-of-its-kind study in which passive collection systems were used to measure levels of 29 volatile organic compounds
in the air of participants' homes over a 4-week period.
It will enable physicians and safety and health professionals to evaluate environmental data from buildings relative to volatile organic compounds
, pesticides, combustion gases, particles, molds, allergens and their impact on the pulmonary and respiratory systems in children and adults.
Low volatile EPS products, those with a pentane level of 4.5% or less, help molders comply with the regulations of the Clean Air Act which madates a reduction in Volatile Organic Compounds
(VOCs) in non-attainment areas.
