To reduce the absorption of VOCs
during construction or modernization, you should create guidelines for the installation of interior building materials.
The first stage highly concentrates VOCs
from the process exhaust, increasing flammability of the gas stream entering the second stage.
The research was conducted in a controlled chamber into which either a relatively high level of the VOC
mixture (26 milligrams per cubic meter), the VOCs
plus moderate concentrations of ozone (40 parts per billion), or clean air with a low one-minute spike of VOCs
For 14 of the VOCs
, all of which are designated as hazardous by the Clean Air Act, the lapel sensors contained much higher concentrations than outdoor samples did.
Investigation of ways to produce purer, more concentrated forms of specific VOCs
suitable for sale as by-product chemicals are also possible.
Our study concluded that no significant amount of VOCs
was found in the products.
Benjamin Moore has been working to reduce VOC
emissions from its paints by reducing the VOCs
in the paints, reformulating various product lines and discontinuing high VOC
With the growing focus on air purification, regulations regarding VOC
limits are becoming increasingly stringent, both nationally and internationally.
The test methods-ASTM D6886 and SCAQMD Method 313--are intended to be used to analyze the VOC
content of coatings less than 150 g/L ("material "or "actual" VOC
After the specimen edges were sealed with aluminum foil to prevent the release of VOCs
, they were stored in Teflon bags and placed in the refrigerator until needed.
The use of plants to lower VOC
concentrations in closed spaces isn't new NASA began studying the option in 1984, discovering that plants absorb the airborne VOCs
with their leaves and roots--but a new approach involves comparing the rate at which multiple VOCs
are simultaneously absorbed by a selection of five popular plants, rather than focusing on one type of VOC
or individual plant species.
A diversified portfolio of new flexible PVC compounds for indoor construction products boasts up to 90% lower VOC
emissions than standard PVCs.
