ASSESSMENT OF ENVIRONMENTAL POLLUTION WITH METALS IN SOME INDUSTRIAL REGIONS OF KOSOVO USING CHICKEN (Gallus gallus domesticus) BREAST FEATHERS

Abstract

The aim of this study was to assess the presence of metals in three regions of Kosovo using chicken (Gallus gallus domesticus) breast feathers collected from the industrial regions of Mitrovica and Obiliq and the non-industrial region of Dragash. This study was carried out from September to November 2016, and feathers were collected from 90 individual domestic chickens housed as free range. The concentrations of metals in the chicken feathers were determined with atomic absorption spectrometry (AAS). The range of average measured concentrations of metals (µg g -1 ) in examined regions were:

Age features and reference intervals for the concentrations of some essential and toxic elements in laying hens

“…The results on the concentration of Cu and Mn in our study were similar to the study conducted in Korea [ 49 , 51 ] and, at the same time, were significantly lower than the study conducted in Belgium [ 52 ]. The received data on the content of Pb and Cd in laying hens bred in the biogeochemical province of the South Urals (Russia) were significantly lower than those observed in South Korea [ 49 , 53 ], Pakistan [ 50 ], Belgium [ 52 ],China [ 54 ], the Republic of Kosovo [ 55 ], and and were practically similar to the results obtained for Nigeria [ 56 ], as concentrations were lower than the data obtained for Belgium [ 57 ] and Malaysia [ 48 ].…”

“…The observed difference in the content of toxic metals in feathers may be related to background pollution with toxic metals in the surveyed areas [ 55 , 58 , 59 ]. Simultaneously, the methodology for the selection and assessment of the mineral composition of substrates can have a significant impact on the results obtained, which makes it challenging to work on a comparative analysis of the results obtained in various studies [ 60 , 61 ].…”

AGE-DEPENDENT ACCUMULATION OF ESSENTIAL AND TOXIC CHEMICAL ELEMENTS IN FEATHER OF ARBOR ACRES BROILERS (Gallus gallus L.) REARED IN THE SOUTH URAL BIOGEOCHEMICAL PROVINCE OF RUSSIA

“…Так, в нашем эксперименте показатели по Zn были выше, чем у цыплят (Gallus gallus domesticus), разводимых в экологически благополучных регионах Малайзии (28), но практически сопоставимы с полученными для этого кросса в Пакистане (29), по Cu и Mn -сравнимы с результатами для Кореи (30) и значительно ниже, чем в Бельгии (31). Содержание Pb и Cd в пере цыплят-бройлеров в нашем исследовании (Южно-Уральская биогеохимическая провинция России) было значительно ниже, чем у цыплят, разводимых в регионах с высокой техногенной нагрузкой, в частности в Южной Корее (кросс Ross 308, воздействующий фактор -близость к крупному мегаполису) (32), Китае (кросс неизвестен, воздействующий фактор -горнодобывающая металлургия) (33), Республике Косово (кросс G. gallus domesticus, воздействующий фактор -близость к крупному мегаполису) (34), но при этом мало отличалось от показателей для птицы (G. gallus domesticus), разводимой вблизи столицы штата Ойо в Нигерии (35). Наблюдаемые различия могут быть связаны с неодинаковыми региональными и локальными фоновыми загрязнениями токсичными металлами в обследуемых областях (36).…”

ВОЗРАСТНЫЕ ОСОБЕННОСТИ НАКОПЛЕНИЯ ЭССЕНЦИАЛЬНЫХ И ТОКСИЧНЫХ ЭЛЕМЕНТОВ В ПЕРЕ ЦЫПЛЯТ-БРОЙЛЕРОВ (Gallus gallus L.) КРОССА ARBOR ACRES В УСЛОВИЯХ ЮЖНО-УРАЛЬСКОЙ БИОГЕОХИМИЧЕСКОЙ ПРОВИНЦИИ РОССИИ

“…Thus, in our experiment, the indicators for Zn were higher than those for chickens (Gallus gallus domesticus) bred in environmentally safe regions of Malaysia [28], but almost comparable to those obtained for this cross in Pakistan [29], for Cu and Mn, the values were comparable to the results for Korea [30] and significantly lower than in Belgium [31]. The content of Pb and Cd in the fether of broiler chickens in our study (South Ural biogeochemical province of Russia) was significantly lower than in chickens bred in regions with high technogenic load, in particular in South Korea (cross Ross 308, influencing factor is proximity to a large metropolis) [32], in China (cross is unknown, the influencing factor is mining metallurgy) [33], in the Republic of Kosovo (cross G. gallus domesticus, the influencing factor is proximity to a large metropolis) [34], but it differed little from indicators for poultry (G. gallus domesticus) raised near the capital of Oyo State in Nigeria [35]. The observed differences may be due to differences in regional and local background toxic metal pollution in the study areas [36].…”
