Analiza porównawcza stężeń oraz profili dioksyn i polichlorowanych bifenyli w paszach
(Państwowy Instytut Weterynaryjny - PIB w Puławach, 2021)Dioksyny (PCDD/PCDF) i polichlorowane bifenyle (PCB) stanowią grupę niepożądanych substancji chemicznych, zaliczanych do trwałych zanieczyszczeń organicznych (TZO). Główną drogą narażenia ludzi na te związki jest dieta ... -
Chickens’ eggs and the livers of farm animals as sources of perfluoroalkyl substances
(National Veterinary Research Institute in Pulawy; Poland, 2024)Introduction: This study focuses on perfluoroalkyl substance (PFAS) content in chickens’ eggs and the livers of farmanimals. Material and Methods: Chickens’ eggs (n = 25) and the livers of cows (n = 10), chickens (n = 7) ... -
Dioksyny, furany i PCB w importowanych rybach morskich – narażenie konsumentów
(Polskie Towarzystwo Technologów Żywności Wydawnictwo Naukowe, 2023)Wprowadzenie. Normy żywieniowe zalecają spożywanie ryb co najmniej dwa razy w tygodniu zewzględu na zawarte w nich cenne składniki odżywcze. Najważniejszymi z nich są długołańcuchowe,wielonienasycone kwasy tłuszczowe, ... -
Dioxin transfer simulation from feed to animal tissues and risk assessment
(PERGAMON-ELSEVIER SCIENCE LTD, ENGLAND, 2022)Dioxins might be introduced into the food chain through a direct or an indirect pathway. The main source of human exposure to dioxins is food of animal origin, whereas feeds are the main route of exposure of farmed animals ... -
Dioxins and PCBs in freshwater fish and sediments from Polish lakes
(2022)PCDD/F and PCB concentrations were analysed in sediments, fish muscles, and livers collected from four lakes in Poland. In general, the fish and sediments had low levels of dioxins and PCBs. The total TEQ in the sediments ... -
Dioxins and polychlorinated biphenyls in insect processed animal proteins used as a feed – is there a health risk?
(Wageningen Academic Publishers, 2022)Insects have all the characteristics necessary to become an alternative source of protein in feed. However, as with feed materials of animal origin, insect processed animal proteins (IPAPs) can also accumulate persistent ... -
Feed materials – Levels and characteristic profiles of dioxins and PCBs
(ELSEVIER, 2024)Dioxins (PCDD/PCDF) are toxic compounds that are ubiquitous in the environment; although present in low concentrations, they are persistent and highly toxic and they bioaccumulate in food chains. Therefore, it is very ... -
Infant formula and baby food as a source of perfluoroalkyl substances for infants
(England : Elsevier Applied Science Publishers, 2022)The present study reports infants’ exposure to fourteen perfluoroalkyl substances (PFASs) in infant formula and baby food. First infant milk, follow-on milk and three types of baby food were analyzed: a variety made of ... -

(Krajowa Izba Lekarsko-Weterynaryjna, 2024)Dioxins (PCDD/PCDFs), and polychlorinated biphenyls (PCBs), still remain ofinterest to the European Union due to their toxic effects even at very low doses.However, it was only after the so-called “Belgian crisis”, that ... -
Occurrence and dietary intake of dioxins, furans (PCDD/Fs), PCBs, and flame retardants (PBDEs and HBCDDs) in baby food and infant formula
(ELSEVIER, 2023)This study determines the levels of 49 persistent organic pollutants which were grouped into polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), polybrominated ... -
Occurrence of perfluoroalkyl substances in cow’s, goat’s and sheep’s milk – dietary intake and risk assessment
(National Veterinary Research Institute in Pulawy; Poland, 2023)Introduction: Milk from cows, goats and sheep was analysed in terms of content of fourteen perfluoroalkyl substances (PFASs). Material and Methods: Altogether, 73 milk samples from cows (n = 38), goats (n = 20) and sheep ... -
Perfluoroalkyl substances in hen eggs from different types of husbandry
(2022)Poultry eggs from cage, ecological and free range production were analyzed in terms of perfluoroalkyl substances (PFASs). Taking into account all fourteen analyzed compounds, perfluorobutanoic acid (PFBA) reach the highest ... -
Perfluoroalkyl substances in the meat of Polish farm animals and game – Occurrence, profiles and dietary intake
(ELSEVIER, 2024)Meat from farm animals (pigs, cattle and poultry) and game (wild boar and deer) was analysed in terms of thirteen perfluoroalkyl substances (PFASs). Wild boar muscle tissue was statistically significantly more contaminated ... -
