Radionuklidi u lancu ishrane na području opštine Grocka

Abstract

U cilju procene uticaja deponije komunalnog otpada na životnu sredinu i lanac ishrane, gamaspektrometrijskom analizom ispitani su uzorci zemljišta, vode, kao i proizvodi biljnog i životinjskog porekla. Uzorci su prikupljeni tokom 2016. godine na području prigradske Opštine Grocka, u naselju Vinča. Rezultati pokazuju da je sadržaj prirodnih radionuklida na nivou karakterističnom za ispitivane vrste uzoraka. Proizvedeni radionuklid 137Cs detektovan je u zemljištu (7,1–41,1) Bq/kg, ali nije uključen u lanac ishrane. Svi uzorci hrane biljnog i životinjskog porekla su radijaciono higijenski bezbedni za ljudsku ishranu.

To estimate an influence of amunicipal waste landfill on the environment and food chain, gamma spectrometric analysis of the various environmental samples is conducted. The samples were collected in the village of Vinča, Grocka municipality, Belgrade, Serbia, during 2016, and included the following: soil at a depth of 0–20 cm and 20–40 cm; water samples from wells and the Danube river; fruit samples of apples, pears, peaches and apricots; vegetable samples of onions, carrots, potatoes, cabbages and corn; products of animal origin used in human diet–eggs, goat milk, goat cheese, pork, pork liver and chicken meat. A content of 40K, 238U, 235U, 226Ra, 214Bi, 232Th, and 137Cs in the samples is investigated. The results show concentrations of the natural radionuclides within the reported ranges for Serbia. The artificial 137Cs is detected in the soil (7.1–41.1 Bq/kg), but not in any of the other samples from the food chain. Therefore, our results imply that the products of plant and animal origin produced in the vicinity of the landfill are radiologically safe for human consumption.
