Обобщены результаты многолетнего мониторинга зеленых насаждений Владивостока. Были обследованы растительность и почвы всех городских парков, большинства скверов, старых садов-скверов, аллейных и рядовых посадок, 34 насаждений внутриквартального озеленения в разных районах города, 6 внутригородских рекреационных лесов. Дана качественная и количественная характеристика зеленых насаждений и озелененных городских территорий различного функционального назначения по комплексу эколого-биологических показателей. Сравниваются видовой состав арборифлоры, виталитет древостоя, качество почвенного покрова, интенсивность накопления тяжелых металлов почвами и растениями, а также напряженность антропогенно-техногенного пресса. Основной целью работы являлись системный анализ состояния зеленых насаждений и методическое обоснование интегральной оценки их функциональной значимости в системе городского озеленения. Была разработана оригинальная методика, в основу которой положен введенный автором сводный показатель – индекс функционального статуса насаждений. На его основе выполнена сравнительная оценка функциональной эффективности городских зеленых насаждений разного назначения. Установлен высокий функциональный статус рядовых посадок и скверов, обусловленный преимущественно активной трансформацией почвами и растениями тяжелых металлов. В 1,5 раза ниже этот показатель для внутригородских рекреационных лесов как следствие их бедного видового состава и низкого жизненного состояния древостоя, а также слабого накопления тяжелых металлов почвами и растениями. Результаты исследований могут служить научно-методической базой при разработке устойчивой структуры городского озеленения и организации рациональной системы мониторинга урбоэкосистем. The article compiles the results of long-term monitoring of green plantings in Vladivostok city. The vegetation and soils of all city parks, most of squares, old gardens, alleys and ordinary plantings, 34 intra-quarter plantings in different parts of the city, 6 urban recreational forests were examined. The qualitative and quantitative characteristics of greenery and urban green areas of various functional purposes are given for a set of ecological and biological indicators. The species composition of arboriflora, the vitality of the stand, the quality of the soil cover, the intensity of accumulation of heavy metals by soils and plants, and the intensity of the anthropogenic-technogenic press are compared. The main purpose of the work was a systematic analysis of the state of green spaces and a methodological substantiation of the integral assessment of their functional significance in the urban greening system. An original methods was developed based on the summary indicator introduced by the author – the “functional status index (IFS) of plantings”. A comparative assessment of the functional effectiveness of urban plantings of various town planning function has been made on the basis of such index. The increased functional status of ordinary plantings and squares, caused mainly by the active transformation of heavy metals by soils and plants, was installed. This index is 1.5 times lower for intra-urban recreational forests and was the result of a few species composition, low vitality of woody species and poor accumulation of heavy metals by soils and plants. The results of this research may serve as a scientific-methodological basis to creation of stability town plantings structure and organize the rational monitoring system of urban ecosystems.

In almost all industrially developed regions of the Russian Federation, the soil is contaminated with heavy metals (HM) often in concentrations which exceed limits of safety. This contamination causes degradation of agricultural land, which underlines the importance of the complex continuous monitoring of the dynamics of on-going changes in urban ecosystems against the background of natural processes. Quantitative assessment of the environmental sustainability of the soil according to the biological indicators of its condition is of enormous importance, in particular the balance of microbial carbon in soils, which are under varying degrees of anthropogenic pressure. Experiments were carried out to determine the phytoremediation potential of the spring rapeseed plants on soil contaminated with heavy metals. The aim of the study was to assess the respiratory activity of albic luvisol at different levels of its contamination with zinc and nickel under the conditions of a growing experiment with spring rapeseed plants. The experimental data on the respiratory activity of soil artificially contaminated with zinc and nickel in the dose range of 400-800 and 30-60 mg kg-1 of soil respectively, showed that microbial activity had a strong positive correlation with the presence of spring rapeseed plants in the vessels and weak correlation on the presence of toxic elements in the soil. According to the respiratory activity of albic luvisol, it was found that in the first 13 days of vegetation, cultivation of spring rapeseed plants had a positive effect on the sustainability of soil microbiocenosis to complex pollution with zinc and nickel.

This article assesses the resistance of brown forest soils of the Republic of Crimea, the Western and Central Caucasus to pollution by lead, chromium, nickel, and copper, and develops regional maximum permissible concentrations of these heavy metals. Soil contamination was modeled under laboratory conditions. Heavy metals were added in the form of oxides. Soil stability assessment was carried out by biological indicators. The brown forest soil of the Republic of Crimea proved to be the most resistant to pollution. The higher stability of the brown forest soils of the Western Caucasus relative to similar soils of the Central Caucasus, apparently, is determined by the higher content of organic matter in them, despite their lower acidity. Heavy metals formed the following series in terms of ecotoxicity for brown forest soils: Cr> Cu ≥ Ni ≥ Pb. The values of regional maximum permissible concentrations of lead, chromium, nickel and copper in the brown forest soils of the Crimea, Central and Western Caucasus are proposed.

The health and environmental risk associated with unlined open waste dumpsites are worrisome. This study, therefore, evaluated the leachate and its final fate on groundwater pollution at selected solid wastes dumpsites in Rivers State. Leachate samples collected near the dumpsites were analyzed to determine the physical and biochemical characteristics. The two studied dumpsites indicated that the computed TCB were 296.33±6.22 cfu/100 ml and 182.68±21.33 cfu/100 ml respectively which were within the permissible limits of 400cfu/100 ml specified by World Health Organization (WHO) and Federal Ministry of Environment (FMEnv); which suggest low quantities of disease-causing agents in the groundwater. The total heterotrophic bacteria (THB) were 21x104 cfu/ml and 17x104 cfu/ml. These high values of THB may not be an indication of contamination of groundwater but it indicates a gradual decline in raw water quality. The values of SO42-, PO43-, TDS, DO, BOD and COD at the dumpsites were 196.52±6.26 mg/l and 9.12±0.59 mg/l, 139.23±3.19 mg/l and 3.81±0.68 mg/l, 5952.23±72.52 mg/l and 12663.33±490.95 mg/l;1.51±0.42. mg/l and 2.02±0.16 mg/l; 31.22±4.12 mg/l and 21.33±3.51 mg/l, and313.30±6.57 mg/l and 270.33±26.16 mg/l respectively which exceeded the standards of the WHO and FMEnv. The high values of analyzed parameters were an indication of the groundwater contamination. Heavy metals in the Rumuosi dumpsite indicated 11.31±1.33 mg/l, 11.01±0.67 mg/l, 361.84±12.31 mg/l, 118.03±5.74 mg/l and 84.77±4.84 mg/l for Pb, As, Mn, Fe and Zn respectively. While Heavy metals thresholds at Igwuruta were 0.004±0.005 mg/l, 0.04±0.07 mg/l, 0.05±0.08 mg/l, 0.08±0.14 mg/l and 0.15±0.04 mg/l respectively. Rumuosi thresholds exceeded the standards, indicating that the exposed local people in the nearby communities may experience cases of non-carcinogenic and carcinogenic health risk by drinking the groundwater. The leachate pollution index (LPI) at the studied dumpsites indicated 13.58 and 12.9 which exceeded the internationally accepted benchmark of 7.38; indicating that the Rumuosi leachate was more polluted than Igwuruta leachate. The analysis of variance (ANOVA) of the pollutant characteristics indicated a significant difference at p=0.05 across the physicochemical and biological indicators at Rumuosi dumpsite over Igwuruta dumpsite. The researcher recommended the practice of sanitary landfill which may reduce the risk of leachate percolation, a primary source of groundwater contamination.

The development of industries and the uncontrolled increase of population, the development of agricultural areas and the use of fertilizers and pesticides have caused industrial and municipal wastewaters as well as agricultural effluents with heavy metals to enter water ecosystems. After entering aquatic ecosystems, heavy metals accumulate in aquatic tissues and eventually enter the food chain. Research on heavy metal pollution in aquatic ecosystems is important from a public health perspective, maintaining the balance of those ecosystems and preventing biodegradation due to the adverse effects of pollutants. So, researchers have focused on determining the level of pollution of various water sources, how metals are absorbed by aquatic animals, bioaccumulation of heavy metals in various aquatic tissues and the possibility of using aquatic animals as biological indicators based on pollutant monitoring. Due to the importance of this issue, the present study has investigated the effect of heavy metals on fish.

Abstract A human bio monitoring study, investigating most consumed fish species exposure to heavy metals was done in northern part of Iran, Miankale Peninsula, in winter 2019. Metals levels were evaluated in various tissues of fish, as well as Turkmen pregnant women’s biological indicators. For this purpose, 20 water and sediment, 14 fish and 16 human samples were collected. Concentration of Cr, Co, Cu, As, Hg and Pb metals were determined by ICP-MS device. The highest mean concentration of Cu and Cr in water (93.35 and 80.91 µg/l respectively), Hg and Pb in sediment (7.4 µg/g for both), Cu and Pb in liver (27 and18.9 µg/g for C.carpio; 1414 and 31.7 µg/g for L.auratus), muscle (10 and 18.8 for C.carpio; 37.2 and 8.27 µg/g for L.auratus), and skin (26.4 and 9.9 for C.carpio; 10.8 and 11.74 µg/g for L.auratus) of both fish species, and Cu in blood (2.53 mg/l), hair (8.87 µg/g), fingernail (36.46 µg/g), and toenail (29.04 µg/g) samples were observed, while Co had the lowest concentration in all samples. Liver in fish samples and fingernail in pregnant women were the tissues with the highest heavy metals accumulation, whereas the lowest concentrations of heavy metals were observed in the muscles of fish species and pregnant women’s blood sample. Hg concentration in water and sediments, the muscle of fish, and pregnant women’s blood and hair samples were higher than the values suggested by various organizations. This study showed that the level of heavy metals, especially Hg, in water, sediments and fish is a threat to human health. Therefore, it is recommended that the necessary information about the consumption of seafood with high amounts of Hg should be provided in this area.
