Investigation and risk assessment of dibutyl phthalate in a typical
The systematic investigation and risk assessment of dibutyl phthalate (DBP) were performed using an ultrasensitive dual-signal immunoassay in Zhenjiang, Jiangsu Province. In this study, [email protected] 2 nanohybrid were synthesized and labelled on the secondary antibody to generate fluorometric and colorimetric signals.

Under optimal experimental conditions, the linearity range of the method for detecting DBP was from 12.5 to 1500 μg/L, with a limit of detection of 5.0 μg/L. Compared with detection results for two structural analogues, this method showed good specificity for DBP.

DpeH shares the highest similarity (53%) with an alpha/beta hydrolase from Microbacterium sp. MED-G48 and MpeH shows only 25% identity with a secreted lipase from Trichophyton benhamiae CBS 112371, indicating that DpeH and MpeH are two novel hydrolases against PAEs.

The maximum DEHP level for drinking water is determined by US EPA as 0.006 mg l 1, based on reproductive difficulties, liver problems, and increased risk of cancer in adult animals. Oral intermediate exposure for DEHP is 0.1 mg kg 1 day 1, based on reproductive effects in adult animals.
- How is dibutyl phthalate (DBP) risk assessed?
- The systematic investigation and risk assessment of dibutyl phthalate (DBP) were performed using an ultrasensitive dual-signal immunoassay in Zhenjiang, Jiangsu Province. In this study, C-dots@H-MnO 2 nanohybrid were synthesized and labelled on the secondary antibody to generate fluorometric and colorimetric signals.
- Can dibutyl phthalate be determined using solid phase extraction and gas chromatography?
- The aim of the work described here was to develop and validate a method by which dibutyl phthalate may be subject to determinations using solid phase extraction and gas chromatography. Optimization of the chromatographic method was based on the selection of working conditions for both the chromatograph and the detector.
- Can polypyrrole be used to detect dibutyl phthalate?
- Electrochemical detection dibutyl phthalate An efficient approach that integrates a molecularly imprinted conducting polymer, polypyrrole (PPY) with a sensitive electrochemical impedance sensing platform for the quantification of dibutyl phthalate (DBP) was presented.
- Can a dual-signal Elisa detect dibutyl phthalate (DBP)?
- Volume 425, 5 March 2022, 127991 A dual-signal ELISA for dibutyl phthalate (DBP) detection was developed. Attributed to the high C-dots loading of H-MnO 2, a good performance produced. DBP occurrence in aquatic environments and beverages were investigated. Compared with 2016, DBP pollution in waters has been improved.
- What is dibutyl phthalate (DBP)?
- [Google Scholar] Articles from Iranian Journal of Pharmaceutical Research : IJPR are provided here courtesy of Brieflands Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment.
- Can a surrogate analyte be used to determine DBP in hexane samples?
- Standard addition method or using artificial matrices reduce the precision and accuracy of the results. In this study a surrogate analyte approach that is based on using deuterium labeled analyte (DBP-d4) to construct the calibration line was applied to determine DBP in hexane samples.
