Bisphenol A and other Bisphenols

In this study, the potential endocrine and genotoxic effects of bisphenol A and bisphenol S in juvenile brown trout (Salmo trutta) were investigated.

The effects  of the exposure to these compounds on the thyroid hormone levels and the estrogenic disrupting marker vitellogenin were evaluated, along with the genotoxic markers micronucleated cells and erythrocyte nuclear abnormalities.

Bisphenols A and S bioaccumulation were analyzed from fish liver tissue after a clean-up with AFFINIMIP® SPE Bisphenols.

In this study, the simplification and optimization of a method of determination of the free (aglycone) BPA in foodstuffs is proposed for sheep muscle tissue, kidney and liver. A single MISPE purification step is carried out prior to HPLC-FLD analysis. The recovery rates and RSD values over a concentration range of 1‒10 µg/kg were in the range of 67‒86% and 3‒34%, respectively. LOD values were 0.5‒1 μg/kg and LOQ values were 1 μg/kg. Linearity over this range of concentration was verified.

This publication shows the validation of an accurate and very sensitive method for the simultaneously quantification of BPA, 17_-Estradiol and testosterone in two target tissues (testis and visceral fat mass).

The protocol requires a cleanup with AFFINIMIP®SPE columns prior to LC-MS/MS quantification. The use of these columns allows obtaining high percentages of process efficiency (68.0–83.3% for testicular tissue; 63.7–70.7% for visceral fat mass). Good repeatability and reproducibility was observed and the linearity verified in both tissues. The validated method can be efficiently applied for direct biological monitoring in testis and visceral fat mass from mice exposed to BPA. The quantification of compounds in a single assay could be achieved without a loss of sensitivity.

An innovative complementary approach using a liquid chromatographic-mass spectrometer method and infrared spectroscopy is proposed for measuring internal biological exposure to dangerous chemical contaminants and for monitoring biochemical changes in target organs. The proposed methodologies were validated and applied in the case of rats exposed to low-doses of Bisphenol A (BPA). A liquid chromatographic method coupled to a tandem mass spectrometer was used in order to measure BPA concentration in rat livers after a clean up with AFFINIMIP®SPE BISPHENOLS.

The aim of the study was to preliminarily evaluate the bisphenol A exposure and disposition in sheep milk after repeated dietary and subcutaneous administration of a relatively low dose (100 μg/kg of b. w./day) of bisphenol A to a sheep. A toxicokinetic model was developed on the basis of the analysis of blood plasma and milk cleaned-up with AFFINIMIP SPE Bisphenols.

A LC/ESI-MS/MS method for unconjugated BPA levels in human plasma is proposed. The method was in-house validated, and is sensitive, accurate and precise. The linearity of the detector response was verified in human plasma over the concentration range 0.100-200 ng mL-1. The detection limit was 0.03 ng mL-1 and the quantification limit was 0.100 ng mL-1. The analytical features of the proposed in-house validated method were satisfactory: precision was Human plasma samples from individuals affected by liver disease has been analyzed. An association between liver health status and BPA exposure has been observed.
