A Fluorescence Polarization Immunoassay Procedure for Determining
Abstract We developed a fluorescence polarization immunoassay (FPIA) procedure for determining the dibutyl phthalate (DBP) plasticizer, a toxic technogenic environmental pollutant, in water. The procedure is based on the competitive interaction of DBP and fluorophore-labeled DBP with antibodies in the sample, fluorescence excitation by plane-polarized light, and recording the fluorescence

Because phthalate plasticisers cause great harm to the human body, they are prohibited from use in any food, medicine or health care products. As one of the common phthalate plasticiser, a method is urgently needed to detect the content of dibutyl phthalate (DBP) in food samples.
Dibutyl Phthalate - an overview | ScienceDirect Topics
In the following example, the glass forming dibutyl phthalate (DBP), with a glass temperature Tg =178 K, was investigated by NFS (sensitive to translational and rotational dynamics) and SRPAC (sensitive only to rotational dynamics) ( Sergueev et al., 2003 ). Ferrocene was used as probe molecules.
Dibutyl phthalate 99 84-74-2 - Sigma-Aldrich
Dibutyl phthalate (DBP) is most commonly used as a plasticizer in a variety of household products. It has the ability to leach and evaporate into the environment while using or disposing of these products. [ 1] [ 2] Therefore, studies are being conducted to assess its toxic and apoptotic effects.

Reference Method of Measurements of the Content
The article considers the problems of environmental pollution by phthalates and the impact of phthalates on human health. The article describes the process of developing a reference method of measurements (RMM VNIIM-243-01-2025) of the mass fraction of esters of ortho-phthalic acid (dimethyl phthalate, diethyl phthalate, di(n-butyl) phthalate, benzylbutyl phthalate, di(2-ethylhexyl) phthalate
- 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.
- 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.
- 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 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.
- 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.
- What is the concentration of DBP in different beverages?
- As shown in Table 2, the concentration of DBP in diverse beverages ranged from 0 to 553 μg/L, with the detection frequency varying from 20% to 83.3%. Among different beverages, the detection frequency and mean concentration of DBP varied greatly.
