BACKGROUND Human exposure to phenols, including bisphenol A and parabens, is widespread. Evidence suggests that paternal exposure to environmental chemicals may adversely affect reproductive outcomes. OBJECTIVES We evaluated associations of paternal phenol urinary concentrations with fertilization rate, embryo quality, implantation, and live birth. METHODS Male-female couples who underwent ...

Human exposure to parabens as a preservative used in personal care products is of increasing concern, as there is evidence from in vivo and in vitro studies of hormone disruption in association with exposure to parabens. Transport across the placenta could be critical for risk assessment, but the available data are sparse. The aim is to develop a method for estimating fetal exposure, via the pl...

Parabens are widely used as antimicrobial preservatives in cosmetic products and pharmaceuticals. Therefore, their presence the environment is considered to be serious determination important. This paper reports development validation of a new method based on solid-phase microextraction (SPME) high-performance liquid chromatography – tandem mass spectrometry (HPLC-MS/MS) for simultaneous five p...

Abstract A new, sensitive, stability-indicating reversed-phase HPLC method was validated and applied for the simultaneous quantitation of sodium valproate two paraben preservatives; methylparaben, propylparaben in liquid dosage form. Stability tests were carried out through exposure analyte's solution to stress conditions. Separation analytes achieved on (waters) C18 Column (150 mm × 3.9 mm, 5 ...

Abstract In the present study, potential of Alternanthera spp and its associated rhizobacteria to uptake biodegrade methylparaben (MP) under hydroponic conditions was assessed. The experiments were conducted in vitro using glass reactors 500-mL volume. results indicated that removal rates significantly higher (66.6±3%) than control (<40%). MP reduction data fitted well a first-order kinetics...

Antimicrobial agents are added to a wide variety of products such as cosmetics reduce the risk microbial contamination and ensure suitability safety product. However, recent studies have shown that these compounds can negative effects on human health environment. Therefore, it is crucial develop analytical methods control amount in personal care guarantee product quality. This paper presents an...
