For example, nitrite may be measured as nitrite ion or expressed as N. A standard of "nitrite as N" set at 1.4 mg/L equals a nitrite ion concentration of 4.6 mg/L.
Prior to the release, 1,4-dioxane was measured at 2.4 parts per billion in the Haw, below the Environmental Protection Agency’s health advisory goal of 35 ppb. After the release, The N&O ...
Sanford is calling on two state agencies to say what they know regarding the 1,4-dioxane contamination first discovered a decade ago in the city’s wells, including at what concentration and over ...
The uncertainty and variability in the dose–response relationship of dioxins in terms of their toxicity, as well as the ability of dioxins to bioaccumulate, have led WHO experts to recommending very low tolerable daily intake (TDI) of dioxin, 1-4 pg/kg body weight per day, i.e. 7x10 −11 to 2.8x10 −10 g per 70-kg person per day, to allow ...
