She has discovered the substances which poisoned her were Lindane, Pentachlorophenol
and Borester 7 - all strong industrial chemicals.
The bill would allow methyl bromide and pentachlorophenol
, which is used to fumigate utility poles, to be used until Dec.
(PCP) was found in nearby Cricket Spring in 1987, and the top two to four feet of soil on plant grounds was contaminated.
While current regulations list allowable discharge levels of pentachlorophenol
and trichlorophenol, the advance copy of the proposed rule simply notes that the EPA is "reserving" standards for toxic pollutants.
Over the last two years the pulp and paper industry has moved in advance of the regulations by eliminating the use of woodchips contaminated with pentachlorophenol
and by using a reformulated defoamer free of dioxin precursers.
NYSE:KMG), is disappointed to report that the Persistent Organic Pollutants Review Committee of the Stockholm Convention at its Eighth Meeting in Geneva this week ignored sound science by recommending the listing of pentachlorophenol
(penta) as a Persistent Organic Pollutant (POP).

and its salts and esters, the Committee adopted a risk profile and decided to move the chemical to the next review stage, the development of a risk management evaluation.
Ultrasonic cavitation was shown to significantly increase the longitudinal permeability of the more permeable sugar maple by Chen and Simpson (1992), while Avramidis (1998) reported that ultrasound enhanced the absorption of chromated copper arsenate and pentachlorophenol
in small sapwood specimens under atmospheric pressure.
We illustrate this point in the discussion by estimating an IPR for pentachlorophenol
from an historic interpretation incorporating multimedia fate and transport modeling as a basis for estimating population intake.
