Beneficial Use - Placement of sewage sludge onto land in a manner which complies with the requirements of 30 TAC Chapter 312 Subchapter B and does not exceed the agronomic need or rate for a cover crop or any metal or toxic constituent limitations which the cover crop may have.
Dioxins have different toxicity depending on the number and position of the chlorine atoms.
Toxic equivalency factors inorganic. Dioxins have different toxicity depending on the number and position of the chlorine atoms. Because dioxins refer to such a broad class of compounds that vary widely in toxicity the concept of toxic equivalency factor TEF has been developed to facilitate risk assessment and regulatory control. TEFs exist for seven congeners of dioxins ten furans and twelve PCBs.

035 3 vegetable oils and their by-products. 05 3 Feed materials of mineral origin. The results suggested that DLPs of the brominated congeners for chicken-like Ile324_Ser380 species did not always follow World Health Organization toxicity equivalency factors of their chlorinated analogues.
For ring-necked pheasant-like Ile324_Ala380 and Japanese quail-like Val324_Ala380 species the difference in DLP for several congeners was 1 or even 2 orders of magnitude. As regards inorganic tin the SCF concluded in its opinion of 12 December 2001. In order to be able to sum up the toxicity of these different congeners the concept of toxic equivalency factors TEFs has been introduced to facilitate risk assessment and regulatory control.
This means that the analytical results relating to all the individual dioxin and dioxin-like PCB congeners of.

In its draft dioxin health assessment document 420 the US EPA reviewed the existing literature and provided estimates for dioxin emission factors from internal combustion engines as listed in Table 4 in pico-grams per km and pico-grams per liter of fuel.
The emission factors are expressed as toxicity equivalency factors TEQ based on the toxicity of TCDD and TCDF. The following table contains the various dioxin-like toxicity equivalency factors for Dioxins Furans and dioxin-like PCBs Van den Berg et al. For relatively less toxic inorganic and semivolatile contaminants.
For more information on the sat value in the SL Table please see the discussion in Section 511. For more information on the max value in the SL Table please see the discussion. The calculation of benzapyrene equivalents BaPYR-equivalents is the product of the PAH concentration by its toxic equivalency factor TEF.
The values of these factors are published by Nisbet. The possibility of calculating these factors for the Antarctica soils was explained in the work earlier. Ultimate BOD BODu by BOD Bottle Method Concentrations of NO3-N and NO2-N of the incubated sample are measured on day 0 and on the last day of incubation if interested in nitrification rates then measuring at regular intervals is needed - oxygen equivalency of nitrification is computed and subtracted from the exerted oxygen demand Oxygen equivalency of nitrification of NH3N to NO3.
Two factors might have to be considered. Is the waste stream liable to change such that the other fluid might have to be chosen occasionally. Secondly when performing 714-7144 on the waste in question is the measured pH in the vicinity of the pH 50 decision point.
If it is not close to the decision point and the waste stream is stable the wrong extraction fluid could not be chosen and. If the wastewater were to be discharged without treatment then the adverse effects would include depletion of dissolved oxygen toxic effects on fish and other aquatic organisms and unacceptable changes to color turbidity temperature and solids content of the receiving waters. Issues related to toxicity have been the focus of much attention Walden and Howard 1981.
