Jazmurian playa was an ephemeral lake with a large catchment in southeast iran, which dried up over the last 10 years as a result of prolonged drought. As the lake was recipient of incoming industrial water with trace metals deposited to the sediment, the dust is the cause of environmental concern of the region and requires evaluation and better management. The aim of this study was to evaluate the environmental and ecological pollution of Jazmurian playa. Hence, 24 collected surface sedimentary samples were analyzed with ICP-OES. The environmental pollution indices including degree of contamination (cd), geoaccumulation index (igeo), enrichment factor (ef), pollution load index (PLI) and potential ecological risk (PER) were determined. The study revealed moderately to strongly pollution levels of pb, ni and Al, while Dy, pb, Y, Yb, Sm, te, U, cu, Mn, Sc represented moderate pollution. The EF values indicated four sites were highly enriched with Dy, Pb and Ni. The PER results showed high risk for four sites and considerable risk for others. Cluster analysis illustrated interconnection between the contaminants and the sites with major pollution at six sites. Obviously, climate change has considerable complex environmental impacts through transformation of local water and sediment pollution problem.

На пiдставi розробленого алгоритму оцiнки санiтарно-токсикологiчних властивостей системи «Гальваношлам − природний об'єкт» з використанням модельного мiдно-цинкового шламу. Iдентифiковано мiнерали гальваношламу, що мiстять iони важких металiв-ZnSO 4 •H 2 O, ZnSO 4 •7H 2 O, Cu 3 (OH) 4 (SO 4), (Zn 3.2 Cu 0.8)(SO 4)(OH) 6 •4Н 2 О, якi при тривалiй взаємодiї з навколишнiм середовищем можуть утворювати легкорозчиннi токсичнi сполуки. Встановлено, що процес нейтралiзацiї сульфатних мiдно-цинкових розчинiв вапняним молоком протiкає в два етапи: утворення полуводного i двуводного гiпсу; утворення сполук важких металiв. Вивчена водно-мiграцiйна активнiсть iонiв Cu 2+ i Zn 2+ , якi входять до складу гальваношламу. Доведено, що з двох дослiджуваних металiв катiони Zn 2+ вносять бiльший внесок в негативний вплив на об'єкти довкiлля в порiвняннi з катiонами Cu 2+. Дослiджено особливостi розподiлу i мiграцiї iонiв важких металiв у ґрунтах пiсля забруднення їх гальваношламом. Встановлено, що iнтенсивнiсть трансформацiї iонiв Zn 2+ та Сu 2+ з гальваношламiв до ґрунту визначається типом ґрунту i фiзико-хiмiчними властивостями самих металiв. Встановлена кореляцiя мiж рухливiстю iонiв важких металiв i кислотнiстю ґрунтiв. Для Zn 2+ максимальна рухливiсть спостерiгається в ґрунтах з рН≈7. Для Сu 2+ рухливiсть в нейтральних або лужних ґрунтах нижча, нiж у ґрунтах з кислим середовищем. Визначено основнi кiлькiснi показники потенцiйної фiтотоксичностi гальваношламу-всхожiсть, енергiя, дружнiсть i тривалiсть проростання насiння тест-рослин. Показано, що сумiсна дiя Cu 2+ i Zn 2+ проявляється як в iнгiбуваннi, так i в стимулюваннi ростових процесiв тест-рослин i визначається, перш за все, бiологiчною специфiкою самої тест-культури, а також властивостями ґрунту i ступенем їх забруднення. Представлений в роботi порядок виконання дослiджень дозволяє прогнозувати небезпеку гальваношламiв для навколишнього природного середовища. А також, може бути застосований природоохоронними i проектними органiзацiями при проведеннi агроекологiчного монiторингу Ключовi слова: алгоритм, вiдходи виробництва, гальваношлам, санiтарно-токсикологiчнi властивостi, екологiчна безпека

“…However, it is undeniable that the PTEs can undergo chemical phase changes and spatial migration with changes in time and regional environments (irrigation, crop planting, soil properties, soil erosion, atmospheric dust fall, etc. ; Bi, Zhou, Chen, Jia, & Bao, ; Caporale & Violante, ; Han et al., ; Shi et al., ). To minimize the impacts of time and regional environments on the content distribution of PTEs, a small spatial scale study was conducted.…”

The ecological environment in Central Asia is vulnerable to pressure from human activity due to the physical geography and climatic fragility of this region. A set of indicators suitable for the future assessment of this pressure needs to be proposed.Thirty-six topsoil samples (0-5 cm) were collected from roadsides in a suburban region of Bishkek, the capital of the Kyrgyz Republic in Central Asia, and a risk assessment of anthropogenically disturbed potentially toxic elements (PTEs) was systematically conducted with classic statistical methods. The results of detrended correspondence analysis and principal component analysis clearly showed that topsoil samples with high contents of PTEs (Pb, Zn and Cu) were strongly affected by traffic within a distance threshold of 200 m and that anthropogenic effects decreased significantly with increasing distance from the highway. The enrichment factor and anthropogenic contribution for Pb were the highest among the three PTEs, with average values of 2.0% and 47.4%, respectively, suggesting enrichment. However, the results of the human health risk assessment also indicated that noncarcinogenic risks did not occur for any of the anthropogenic PTEs. The reported method provides a new systematic pathway to reveal anthropogenic influences on the geochemical composition of soil. The conclusions of this work will be highly valuable as important guidelines for agriculture, and the results of the PTE contents will provide a scientific basis for soil collection in future studies.
