Relationship between Eating Habits and Nonylphenol Concentration in Breast Milk of Women in Slovakia

Adriana Repková Csilla Mišľanová Janka Hrabčáková Marián Masár Zuzana Slezáková

: Nonylphenol is an endocrine disruptor who belongs to alkylphenol group of chemicals and its high occurrence in the environment can caused an adverse effect on human health. The breast milk can serve as a marker to take measure of human exposure to these chemicals through different routes of exposure. In this study, the influence of different factors (kind of wastes mothers drink, consummation of fish, pork and beef; using gloves, mail polish, using vitamins and medication) on the concentration on nonylphenol in breast milk were studied. Concentrations of nonylphenol in breast milk were determined by high-performance liquid chromatography (HPLC) with fluorescence detection. The lowest and highest concentration of nonylphenol in breast milk was 0.97 ng/mL and 4.37 ng/mL, respectively. The selected factors such as pork, beef, fish consumption, vitamin supplementation, medication, using of gloves, nail polish and gel nails were observed in relation to 4-nonylphenol concentration.

Analysis of natural aroma and flavor of MD2 pineapple variety (Ananas comosus [L.] Merr.)

Acta Chimica Slovaca (2013)

Lukáš Žemlička Peter Fodran Emil Kolek Nadežda Prónayová

Abstract Aroma and flavor profile of MD2 pineapple variety was investigated. Fruits imported from different geographical regions (Costa Rica, Puerto Rico) were labeled as an organic food. Characteristic volatile and non-volatile compounds obtained by hydro-distillation and direct percolation were identified and quantified by gas chromatography-mass spectroscopy (GC/MS). At least 22 components in percolated extract (or 17 in distillate) were detected according to their mass spectra and retention time. Relative concentration of identified substances varied from 547.7 to 1110.0 μg.kg -1 . Analysis showed dominance of esters and furanone-derived compounds as major aroma constituents. Most abundant volatiles identified in all samples were methyl 2-methylbutanoate and methyl hexanoate. Relationships between volatile and non-volatile compounds were also studied.

Influence of Selected Lifestyle Factors on Nonylphenol Concentration in Breast Milk of Mothers in Slovakia

Adriana Repková Csilla Mišľanová Janka Hrabčáková Marián Masár Soňa Wimmerová

Nonylphenol is a endocrine disruptors who belongs to alkyphenol groups. It´s high occurrence in the environment can caused an adverse effect on human health. The breast milk can serve as a marker to take measure of human exposure to these chemicals through different routes of exposure. In this study, the influence of different factors (including the length of accommodation, kind of wastes mothers drink, con summation of fish, pork and beef; using gloves, mail polish, using vitamins and medication) on the concentration on nonylphenol in breast milk were studied. The length of accommodation has a statistically significant effect on nonylphenol, concentration in breast milk (p value was 0.02). Other mentioned factors had not a significant influence on nonylphenol values.

Relationship between Eating Habits and 4-Nonylphenol Concentration in Breast Milk of Women in Slovakia

Life (2023)

Adriana Repková Csilla Mišľanová Janka Hrabčáková Marián Masár Zuzana Slezáková

4-Nonylphenol belongs to the alkylphenol group of chemicals, and its high occurrence in the environment can cause an adverse effect on human health. Breast milk can serve as a marker to take measure of human exposure to these chemicals through different routes of exposure. In this work, the influence of selected factors (the kind of water drank by the mothers; the consumption of fish, pork, and beef; wearing gloves; using nail polish, gel nails, vitamins, and medication) on the concentration on 4-nonylphenol in 89 breast milk samples was studied. The concentrations of nonylphenol in breast milk were determined by HPLC with fluorescence detection. The lowest and highest concentrations of 4-nonylphenol in breast milk were 0.97 ng/mL and 4.37 ng/mL, respectively. Statistical significance was observed for the consumption of pork (p = 0.048) and fish (0.041) in relation to the 4-nonylphenol concentration. Certain parameters (use of gel nails, beef consumption, and vitamin supplementation) were at the border of statistical significance (p = 0.06). Other parameters did not show any statistical significance. The results showed that breast milk in Slovakia does not contain a harmful dose of 4-nonylphenol and does not cause health problems. But it is necessary to continue this research and perform extended screening on a larger number of samples.
