Summary: | Persistent organic pollutants are mainly compounds that include chlorine, which are posing a threat to human health and impairing living organisms and ecosystems due to their toxicity, persistence, and bioaccumulation. National authorities have the responsibility and obligation to ensure that toxic chemicals are not present in food at levels that may adversely affect the health of the consumers. The concentrations of polychlorinated dibenzodioxins/polychlorinated dibenzofurans and dioxin-like polychlorinated biphenyls in food samples (pork, mutton, beef, poultry, butter, milk, eggs, fish preserves, and rape oil) were analysed and compared to overall food consumption data in Estonia. The results indicated that the food consumed in Estonia was safe concerning these chemicals and that the recommended two servings of fish a week would not be harmful to Estonian people's health.Original Abstract: Pusivad orgaanilised saasteained (POS) on pohiliselt halogeene sisaldavad uhendid, mis oma murgisuse, pusivuse ja bioakumuleeruvuse tottu ohustavad inimese immuun-, narvi- ning sisesekretsioonisusteemi ja paljunemisfunktsiooni, pohjustades kasvajate teket. POS kahjustavad ka teisi elusorganisme ja okosusteeme. Kuna Eestis puuduvad voimalused analuusida poluklooritud dibenso-p-dioksiine (PCDD) ja furaane (PCDF) ning dioksiinidesarnaseid poluklooritud bifenuule (DL-PCB), telliti analuusid Soomest Riigi Terviseuuringute Instituudist (National Public Health Institute). Toiduainete proovide votmisel lahtuti Euroopa Liidu oigusaktidest: Komisjoni soovitus 2006/794/EÜ PCDD-de, PCDF-ide, DL-PCB-de ja muude PCB-de taustanivoode seire kohta toiduainetes; Komisjoni maarus (EÜ) nr 1883/2006, millega satestatakse proovivotu- ja analuusimeetodid PCDD/F-ide ning DL-PCB-de ametlikuks kontrolliks teatavates toiduainetes. Saadud tulemusi vorreldi Komisjoni maaruses (EÜ) nr 1881/2006 satestatud saasteainete piirvaartustega toiduainetes. Analuusitud Eesti toiduainete proovides - sea-, lamba-, linnu-, loomalihas, vois, piimas, munades ja Soome ning Riia lahe raimes ja rapsiolis - olid PCDD-de, PCDF-ide ning DL-PCB-de sisaldused oluliselt vaiksemad Komisjoni maaruses (EÜ) nr 1881/2006 satestatud piirvaartustest ja ilmselt ei kujuta ohtu Eesti elanike tervisele. Laanemere-aarsete maade inimesed saavad dioksiine pohiliselt kalast. Eestis tarbiti 2000. aastate algul 16,6 kg kalatooteid keskmiselt uhe elaniku kohta. Vordluseks oli 1937/38. aastal vastav kogus Eestis 28,5 kg. Üldiselt arvatakse, |
