“…The main applications of synthetic polymers are food packaging, the building industry, the electrical and electronics industry, daily life items (furniture, toys, fibers, clothes), and many more. One of the compound which can be found in plastics is bisphenol A (BPA), a chemical with endocrine-disrupting potential (Corrales et al 2015 ; Vahedi et al 2016 ; Murphy et al 2019 ). BPA, discovered in 1891, is a monomer for the synthesis of selected polycarbonates (PC), epoxy and vinyl ester resins, and polysulfones.…”

The study focused on the application of GC in the quantitative analysis of bisphenols and their analogues (12 analytes), and the improvement of solid-phase extraction for the whole water analysis of complex water samples. The role of silylation in the qualitative and quantitative analysis of bisphenols was investigated. Partial degradation occurred for selected targets during hot injection with the presence of a silylation agent. A PSA (primary and secondary amines) sorbent placed on the top of the solidphase extraction (SPE) column sorbent was found to be a matrix component trap, mostly for humic acids. The whole water analysis was performed by washing the filters with methanol and recycling the extract to the sample. The validation of SPE-GC/ MS(SIM) gave limits of detection of 1-50 ng/L for ten target bisphenols with a method recovery of between 87 and 133%. The application of the method was tested by the analysis of wastewater sampled from three wastewater treatment plants located in Poland, and municipal surface waters. The only analytes found were BPA and BPS, within the range of 16-1465 ng/L and < MDL-1249 ng/L in wastewater, and 170-3113 ng/L and < MDL-1584 ng/L in surface water, respectively.

“…For example, studies reporting effective methods for BPA estimation like gas chromatography–mass spectrometry, LC–MS/MS (Caban & Stepnowski, 2020; Kato et al, 2005). Most of these reported methods also have used the highly expensive solid‐phase extraction in BPA biomonitoring, using environmental samples for research outcomes (Caban & Stepnowski, 2020; Murphy et al, 2019). Moreover, this study reports a less time‐consuming method of BPA estimation in patients for the first time in a South Indian population using robust case–control design compared with previous reports (Murphy et al, 2019).…”

A simple, reproducible and sensitive liquid chromatography (HPLC) method has been developed and validated for estimation of bisphenol A (BPA) in human urine. A simple liquid–liquid extraction technique was used in BPA sample preparation. The analyte was chromatographed on a Shimadzu Prominence HPLC system using isocratic mobile phase conditions at a flow rate of 0.500 ml/min and a Hypersil Gold C18 column maintained at 40°C. Quantification was performed on a fluorescence detector set at excitation 275 nm, emission 313 nm and bisphenol B was used as internal standard. The total run time was 8 min. The method was found to have acceptable sensitivity, selectivity, accuracy (98.82–103.64%), precision (1.17–5.36) and stability in the validation experiment carried out as per the USFDA guidelines. The method sensitivity was as low as 0.50 ng/ml. The applicability of the validated analytical method was established in human patient urine samples. The mean human urine BPA concentrations were 1.18 ± 2.11 ng/ml in the control group and 5.76 ± 6.00 ng/ml in the patient group (P < 0.001). Therefore, this method could be considered as an alternative for routine bio‐monitoring of BPA which is less expensive and feasible in resource‐poor settings.

“…Nevertheless, the case/control studies do not clarify the doubt. Two papers confirm the positive association , even if in one case [19] the sample dimension is too low (54 cases and 47 controls) for a robust result, the work of Murphy et al [23] seems to be more consistent in this respect, but the third paper [25] with a useful number of subject does not confirm the starting hypotesis.…”
