Breast milk samples from professionally unexposed mothers who gave their milk to the lactarium of the Pediatric Hospital in Bratislava were analysed for polychlorinated biphenyls, organochlorine pesticides and chlorinated benzenes; the method used was a capillary gas chromatography with 63Ni electron capture detection; the capillary column was an HP PONA.
Allergic diseases are on the rise in both prevalence and severity, especially in industrialized countries. The process of allergic sensitization needs an understanding of the role environmental factors play in its development. In addition to traditionally considered air pollutants, various persistent organochlorine pollutants, which accumulate in the human(More)
The paper deals with the isolation of chlorinated phenols, benzenes and insecticides from water, soil and vegetable samples. A review of the current procedures is presented. Solid-phase extraction on Empore extraction discs was experimentally evaluated for isolation of the compounds from surface and ground waters. For the isolation of chlorophenols from(More)
A method has been developed for the isolation, separation and determination of chlorinated phenols in total diet. The isolation takes place following acid hydrolysis of the conjugates and is performed by simultaneous extraction and distillation with water vapour and toluene. The isolated chlorophenols are removed by clean-up on a Florisil column using a(More)
In the present study, 50 samples of mother milk and 20 samples of adapted cow's milk produced for bottle feeding supplied from the lactarium of the Pediatric Hospital were examined for presence of 6 indicator congeners of polychlorinated biphenyls (IUPAC No. 28, 52, 101, 138, 153, and 180). Congeners No. 138, 153, and 180 were predominant in all samples,(More)
A method is described for the isolation, derivatization, separation and determination of chlorinated phenols and cresols in urine. After acid hydrolysis, solid-phase extraction on Separcol SI C18 was used. Quantification was based on the internal standard method using 2,6-dibromophenol. Before GC determination the isolated compounds were derivatized with(More)
The paper deals with the contamination of human milk with chlorinated phenols. The average and median concentrations of the chlorophenols investigated ranged from 0.75 to 9.74 micrograms.kg-1 and from being not detectable to 5.62 micrograms.kg-1, respectively, for the different compounds. The highest average and median levels were found for(More)
Within an open, non-randomized clinical study, the authors investigated the effect of a three-month therapy by a standard product of so-called essential phospholipids in a group of patients (31 men and 2 women, average age being 45.6 +/- 10.8 years) with toxic liver damage--steatosis and steatohepatitis which have developed after exposure to the(More)
The aim of this study was to estimate the occurrence of the phenotype of poor metabolizers of sparteine (in the frame of sparteine-debrisoquine-dextromethorphane polymorphism) in Slovakia. The authors examined a group of 216 of healthy volunteers (73 women and 143 men, average age of the group 24, 9 +/- 0.4 years), university students coming from various(More)
Chlorinated phenols are widely used in the manufacture of biocides and wood preservatives. 2,4-dichlorophenol administered perorally 3 times a week at a dose of 40 mg in 0.2 ml of olive oil per kg of body weight to guinea pigs increased lipid peroxidation in liver and adrenals after 2 weeks of treatment. A high intake of ascorbic acid (50 mg/animal/day)(More)
