The article presents the results of studies of the microelement composition of feathers of wild birds kept in the conditions of zoos in Moscow and Ivanovo. The aim of the study was to study the content of some heavy metals and arsenic in representatives of the cockatoo subfamily – Cacatuinae (White cockatoo – Cacatua alba, Sulper-crested ccockatoo – Cacatua galerita), and birds of subfamily Psittacinae – Blue-fronted Amazon – Amazona aestiva, Burrowing parakeet – Cyanoliseus patagonus assessing the health status of birds. In 2018–2020, parrot`s feathers were studied for the accumulation of zinc, copper, iron, lead, cadmium and arsenic by the atomic absorption method. The data on the features of the content of chemical elements in different species of parrots are given. In the course of the study, it was found that according to the value of the average content in the feathers of parrots, the studied elements form the following decreasing series: Fe> Zn> Cu> Pb> Cd> As. In parrots kept in zoos, there is a tendency to a decrease in the proportion of zinc and copper in 38,4%, an increase in iron and cadmium in 30,8% and 38,4% of individuals, respectively. Deviations in the fluctuations of lead and arsenic in the studied sample of birds were equally in the direction of increasing and decreasing their content in biosubstrates in 38,4% of individuals; 30,8% of the studied birds in terms of the content of iron, zinc and cadmium in feathers, 46,1% in terms of copper, 23,1% in lead, 7,7% in terms of lead are in a state of “pre-illness” and require additional examinations. In the fan of the parrots, a significant increase in the concentration of lead in the grooves, in comparison with the rod, by 3,98 times and a decrease by 2,83 times in the level of zinc accumulation was established. Revealed a significant average direct relationship between the level of Zn and Pb, Zn and Cd, Cu and Pb, Cu and Cd; Fe and As; Cd and As and inverse average relationship between the level of Pb and Cd; Pb and As in bird feathers. To improve the trace element status of parrot’s zoological institutions, it is necessary to conduct monitoring studies with a frequency of 1 time per six months with an assessment of the level of chemical elements on centile scales.

Представлены результаты исследований микроэлементного состава перьев диких птиц, содержащихся в условиях зоологических учреждений. Целью исследования было изучить содержание некоторых тяжёлых металлов и мышьяка у представителей отряда Фламингообразные Phoenicopteriformes и разработать центильные шкалы для оценки состояния здоровья птиц. В 2018–2020 гг. проведены исследования перьев розового фламинго на предмет накопления цинка, меди, железа, свинца, кадмия и мышьяка атомно-абсорбционным методом. Приведены данные по особенностям содержания химических элементов у розового фламинго – Phoenicopterus ruber roseus. В ходе исследования установлено, что по величине среднего содержания в перьях птиц исследуемые элементы образуют следующий убывающий ряд: Fe > Zn > Cu > Pb > Cd > As. У розовых фламинго, содержащихся в искусственно созданных условиях, наблюдается тенденция к снижению концентрации кадмия у 50,0%, увеличению железа, свинца и мышьяка – у 50,0% особей. Наибольшие колебания в отклонении уровня накопления отмечены в отношении токсичных элементов: Cd, Pb и As, наименьшие – Cu. Средние концентрации Zn, Cu, Fe и Cd установлены у 33,3% особей фламинго, Pb и As – у 16,7% от общего количества изученных птиц. 16,7% исследуемых птиц по уровню содержания цинка и меди, 33,3% – железа, свинца, кадмия и мышьяка находятся в состоянии «предболезни» и требуют дополнительных обследований. Достоверно установлен синергизм между накоплением Fe – As, Pb – Cd, Pb – As и антагонизм между Fe – Cu и Fe – Pb. Для улучшения микроэлементного статуса розового фламинго зоологических учреждений необходимо проводить мониторинговые исследования с периодичностью 1 раз в полгода с оценкой уровня химических элементов по центильным шкалам. The results of researches of microelement composition of feathers of wild birds contained in conditions of zoological institutions are presented. The purpose of the research was to study the content of some heavy metals and arsenic in representatives of the Flamingo Phoenicopteriformes and to develop centile metrics for assessing the health of birds. In 2018-2020 studies of pink flamingo feathers were carried out for the accumulation of zinc, copper, iron, lead, cadmium and arsenic by absorption method. Data on peculiarities of chemical elements content in pink flamingo – Phoenicopterus ruber roseus are given. As part of the study it was found that in terms of the average content in bird feathers the examined elements form the following decreasing series: Fe > Zn > Cu > Pb > Cd > As. In pink flamingos contained in artificially created conditions, there is a tendency to decrease the concentration of cadmium in 50.0%, an increase in iron, lead and arsenic in 50.0% of individuals. The largest fluctuations in the deviation in the level of accumulation were noted for toxic elements: Cd, Pb and As, the smallest – Cu. Average concentrations of Zn, Cu, Fe and Cd were established in 33.3% of individuals of flamingos, Pb and As – in 16.7% of the total number of birds studied. 16.7% of birds under investigation in terms of zinc and copper content, 33.3% – iron, lead, cadmium and arsenic are in a state of "pre-disease" and require additional examinations. The synergism between the accumulation of Fe – As, Pb – Cd, Pb – As and the antagonism between Fe – Cu and Fe – Pb is reliably established. To improve the microelement status of pink flamingo of zoological institutions, it is necessary to conduct monitoring studies once every six months with an assessment of the level of chemical elements on centile metrics.

STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

Introduction. Intensive exploration and processing of mineral raw materials in the Trans-Baikal territory has caused the accumulation of considerable amount of industrial mining waste with high content of chemical elements of different classes of hazard. Currently 33 tailings storage facilities (TSF) accumulating approximately 3 milliard tons of different industrial waste are located in the territory of the region. The aim of the research is the hygienic assessment of soil contamination in the residential areas adjacent to TSFs. Material and methods. Atomic absorption spectrophotometry method was used for the determination of heavy metals. The study presents the results of analyses of 444 samples of gross content of lead, zinc, copper, mercury, arsenic, and cadmium in the soil of Khapcheranga, Sherlovaya Gora, Kadaya, Vershino-Darasunsky, and Vershino-Shakhtaminsky mining villages throughout the duration of 2012 - 2015. Results. During the period of the study the total value of soil contamination with Zc calculated by the median concentrations in Khapcheranga Village amounted to 4.7 6.9, in Vershino-Shakhtaminaky - to 6.7 8.8, which corresponds to the «allowable» level of the contamination. Zc calculation by maximum concentrations has shown the soil to be referred to the category from “moderately dangerous” to “extremely dangerous”; this value in Khapcheranga Village amounted to 48.7 - 235.3, in Vershino-Shakhtaminsky Village - to 23.76 - 164.8. Discussion. In the residential areas the allowable degree of soil contamination was determined to be predominantly observed; Khapcheranga and Vershino-Shakhtaminsky villages are the exceptions. The results of the assessment give the evidence of tge increased lead, cadmium and arsenic content throughout the entire area of the villages, while the highest levels of accumulated toxic substances are registered in the areas located near the TSF Conclusion. Thus, several zones of natural and anthropogenous contamination with increased concentrations of heavy metals and arsenic have been formed in the Trans-Baikal Territory. This dictates the need to study the influence of geochemical anomalies on the health of population.
