Stage 1 and Stage 2 Disinfectants and Disinfection
Taken together, the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (DBPRs) improve drinking water quality. The rules do this by providing protection from disinfection byproducts. Byproducts, if consumed in excess of EPA's standard over many years, may increase health risks. Drinking water comes from source water locations
2. How is DBP used? - GreenFacts
USE The largest usage of DBP in general is as a plasticizers in resins and polymers such as polyvinyl chloride. Plasticizers are materials incorporated into a plastic in order to increase its workability and distendability.
Phthalate Di-butyl phthalate - GreenFacts
DBP is a phthalate with the same core structure as DIDP and DINP but with two shorter side chains attached, each having four carbon atoms. It is an oily liquid that is soluble in fat and to some extent in water. More... The same information on Level 1: Summary Level 2: Details Level 3: Source 2. How is DBP used?
Simple ultrasensitive electrochemical detection of the DBP
The proposed sensor showed a wide linear dynamic range from 0.14 pg mL 1 to 0.35 ng mL 1 and from 0.35 ng mL 1 to 7 ng mL 1 with a detection limit of ≤0.042 pg mL 1, which were evaluated using standard, analytical grade DBP; the limit of quantification was determined using different concentrations of DBP in DI water in

- What is DBP used for?
- arnishes and printing inks. The ubiquity of DBP in consumer products is demonstrated by its wide usage in cosmetics: a perfume solvent and fixative, a suspension agent for solids in aerosols, a lubricant for aerosol valves, an antifoamer, a skin emollient and a plasticiser in nail polish and finger

- What is DBP toxicity?
- er oral or dermal exposure.DBP is mostly hydrolysed to monobutyl phthalate (MBP) prior to absorpt on by the small intestines. No data on biotransformation after dermal and inhalati nal exposure are available.DBP has low acute oral, derma and inhalational toxicity. DBP causes minimal skin, eye and respiratory
- How is DBP excreted?
- xposure were not available. DBP is also excreted in bile and subsequently enters th enterohepatic circulation. No significant accumulation in tissues occurs in laboratory animals af er oral or dermal exposure.DBP is mostly hydrolysed to monobutyl phthalate (MBP) prior to absorpt
- How fast is DBP absorbed?
- phthalates, including DBP.DBP is rapidly absorbed and excreted after oral administration (in rats and hamsters), with ≥ 90% excre ed in urine within 24-48 h. Faecal xcretion is low (1.0-8.2%). DBP was found to be absorbed dermally in rats with approximately 60% being excr ted in urine within a week. In in vitro dermal studies, DBP is absorbed fa
- Is DBP oestrogenic?
