Sažetak
Bisphenol A (BPA) has received a great deal of attention since 1996, when it was classified by the European Commission as a substance of external origin with a harmful effect on human health. Numerous toxicological and biochemical studies have confirmed that BPA has estrogenic properties through its agonistic effect toward the estrogenic receptor, and it was classified as endocrine disruptor. The effects of exposure to BPA can be particularly harmful to the fetus, infants and young children. Contact with BPA at that time may lead to irreversible changes appearing even after much delay. Exposure to BPA increases the risk of miscarriages, genetic defects (e.g. Down’s syndrome), breast and prostate cancer, diabetes, obesity and cardiovascular disease. Thermochromic printing inks, which are widely used in security printing, in thermal printing paper, as temperature indicators, and as a source of various effects in packaging and design often contain BPA as one of the main compounds present in mass fractions of up to several percent. This study presents the BPA determination during anaerobic degradation of thermochromic prints in soil, which simulated the conditions at a landfill site. Thermochromic ink that contains bisphenol A was printed on seven types of papers. The papers were subjected to anaerobic degradation in soil at time intervals from 14 to 150 days. Reversed-phase liquid chromatographic methods with UV-detection were developed to determine the mass fraction of bisphenol A in paper and in soil, and the rate of BPA degradation was estimated. During the anaerobic degradation, mass fraction of BPA in papers decreased from the initial values of 0.126– 0.788 mg g-1 to value close to detection limit of the method of 0.0025 mg g-1. Mass fraction of BPA in soil increased during the anaerobic degradation, and after 150 days ranged from 3.21 ng g-1 to 35.1 ng g-1.
