Fire Retardant Particleboards by Boric Acid and Lithium Compounds

Fire-retardant Treatments for Wood

Boric Acid and Borates

Boric acid and its chemical relatives are pesticides that are derived from the element boron. Boron rarely occurs alone and is typically found in combination with other elements; common combinations are boric acid or borates.1 Unlike many pesticides which are synthetic compounds,2 boric acid and related pesticides are naturally occurring compounds.1 Boron compounds are widely found in rivers, s...

Effects of Fire Retardant on Water Quality1

Ammonium-based fire retardants are important in managing wildfires, but their use can adversely affect water quality. Their entry, fate, and impact were studied in five forest streams. Initial retardant concentrations in water approached levels which could damage fish, but no distressed fish were found. Concentrations decreased sharply with time after application and distance downstream, and th...

Reproductive toxicology. Boric acid.

Boric acid (BA), widely used for both medicinal and nonmedicinal purposes, was known to adversely affect reproduction and fertility in rodents. NIOSH, in evaluating the literature prior to writing a Criteria Document, asked NIEHS to perform an RACB study on BA to generate both structural and functional data to be used for setting exposure criteria (Fail et al., Fundam Appl Toxicol 17:225-239 [1...

Effects of Fire Retardant Chemical and Fire Suppressant Foam on Shrub Steppe Vegetation in Northern Nevada

The objectives of this study were to determine the effects of fire retardant chemical (Phos-Chek G75-F*) and fire suppressant foam (Silv-Ex) application, alone and in combination with fire, on Great Basin shrub steppe vegetation. We measured growth, resprouting, flowering, and incidence of galling insects on Chrysothamnus viscidiflorus and Artemisia tridentata. These characteristics were not af...
