W rozdziale opisano właściwości PCB, źródła zanieczyszczenia środowiska tymi związkami, ich biodegradację oraz transformacje w środowisku, biokumulację, biowzbogacanie oraz wpływ na zdrowie człowieka. Opisano również procesy destrukcji PCBs oraz regulacje prawne dotyczace tej grupy związków

Oznaczono poziom zawartości fenoli w próbkach wód spływnych zbieranych w 5 punktach usytuowanych w pobliżu dróg o dużym natężeniu ruchu pojazdów mechanicznych. Najczęściej stwierdzano obecność fenolu i 3,4-dimetylofenolu natomiast w najwyższych stężeniach występują fenol (120,3-911,6 ng/l), chlorofenol (613 ng/l) oraz p-nitrofenol (469,4 ng/l).

Thermal pyrolysis synthesized activated biochar from the Pinus elliottii sawdust (PS) at 600° C. The obtained activated biochar (PB600) was used for the removal of three diphenols, catechol (CAT), resorcinol (RES), and hydroquinone (HYD), which are utilized mainly in different industries. The PB600 was characterized by several analytical techniques. The BET surface area of 1473 m2.g−1 and a total pore volume of 0.707 cm3 g−1 was...

Metal cations complexation and proton binding by 13- and 16-membered diphenyl-azobenzocrowns and diphenyl-hydroxyazobenzocrowns were studied in acetonitrile using spectroscopic methods: UV–vis spectroscopy, spectrofluorimetry, and 1H NMR spectroscopy. Phenyl moieties in benzene rings were found to affect binding strength alkali and alkaline earth metal cations and hydrogen ion, and affect tautomeric equilibrium of hydroxyazobenzocrowns....

Many common products contain and leach hazardous chemicals, including endocrine-disrupting chemicals such as bisphenols that are harmful to human health. For toddlers, this dangerousness is higher because of their not fully developed detoxification system. Due to this, bisphenols content in products such as baby diapers, should be monitored. Baby diapers not only remain in close contact with the skin, but are also used from the...
