“…, 2007). Those impacts have exposed the aquatic biota of the UPRE to a high ecological risk associated with the metal pollution (Silva, Silveira, & Campos, 2017). Although the phosphorus constitutes an essential element for living organisms, its natural availability in the aquatic habitats is low, making it a limiting factor for the primary productivity (Elser et al, 2007).…”

Fish communities' organisation is a challenging task due to global, local and temporal variations related to biotic and abiotic factors, highlighting anthropic activities. The Verde River Basin (VRB) was chosen as a model to the fish community study due to its complexity, presenting a longitudinal gradient of degradation. The ichthyofauna and abiotic factors were sampled during twelve months in four sites. Analyses employed rarefaction curves with Hill numbers estimators and canonical correspondence analysis. The endemic Apareiodon sp. (not described), Hypostomus albopunctatus, H. strigaticeps, Oligosarcus paranensis, Neoplecostomus yapo and Trichomycterus diabolus were associated with structurally complex and well-preserved environments. In contrary, Astyanax aff. fasciatus, Corydoras ehrhardti, Geophagus brasiliensis, H. ancistroides and Phalloceros harpagos showed tolerance to impacted environments. The methods here employed allowed to identify and explain differences in the ichthyofauna structure, distinguishing the influence of spatial, temporal and human effects on the fish communities.

“…Environmental pollution includes different forms such as organic and inorganic pollutants but the most important and new types are electronic wastes (Awasthi et al 2016;Li et al 2017) and nanoparticle or nanomaterial pollutants (Li et al 2016a;ElRamady et al 2017). The common pollutants include the heavy metals (Li et al 2016b;Chen et al 2016b;da Silva et al 2017), persistent of organic pollutants (Wilson et al 2016;Saha et al 2017b), environmental persistent of pharmaceutical pollutants (Huber et al 2016;Łukaszewicz et al 2017), polycyclic aromatic hydrocarbons (Kenessov et al 2016;Wei et al 2017), volatile organic compounds (Pantoja et al 2016;Yu et al ENVIRONMENTAL NANOREMEDIATION UNDER CHANGING CLIMATE 2017) and environmental xenobiotics (Witczak et al 2016;Hashmi et al 2017). Developing and developed countries suffer from problems resulting from environmental pollution.…”

“…Environmental pollution nowadays is considered a major human and environmental problem (Noguera-Oviedo and Aga 2016; Hashmi et al 2017). This environmental pollution can be defined as any discharge of material or energy into natural resources (i.e., water, land, air, forest, etc) causing or may cause acute (through short-term) or chronic (through long-term) damage to the universe (da Silva et al 2017). Several sources of pollution or many synthetic substances represent these sources including (1) the natural activities (geological erosion and saline seeps), (2) the human activities (e.g., construction and mining), (3) industrial activities, (4) agricultural activities (e.g.…”

MANY global problems threaten our life on the Planet including climate changes, environmental pollution, food and soil security, energy crisis, etc. This environmental pollution has not only mainly serious risks and stress involving the human health and safety of the entire ecosystem but also the quantity and quality of crops productivity worldwide. Due to the great gap between the global food production and the global consumption, there is a crucial need to cultivate these contaminated lands sooner or later. Therefore, the removing of pollutants from soils and waters should be performed in frame of sustainable remediation and sustainable energy production accordingly. Depending on many factors (source and kind of pollutants, land use and the economics of water and soil resources, etc) many strategies should be addressed for the sustainable and integrated management of polluted lands. Nanoremediation is a promising strategy in controlling pollution and management. Three major applications of nanoremediation could be characterized including detection of pollution using nanosensors, prevention of pollution, purification and remediation of contamination. Further studies also concerning the impact of changing climate on the nanoremediation process in the agroecosystems should be considered. Thus, this review will focus on the evaluation of environmental nanoremediation and its strategy in polluted lands under climate changes. Using of nanotechnology in pollution control as well as the environmental pollution and its sustainable management also will be highlighted.Keywords: Environmental nanoremediation, Climate change, Pollution, Crop production, Environmental stress. IntroductionClimate changes are a great challenge facing the human kind as well as other living things. The production of crops and other agricultural features are extremely susceptible to changes in climate. So, these global changes will be caused major shifts in crop distribution due to climate changes in the future. Moreover, it has been estimated that climate changes are likely to reduce yields and/or damage crops in the 21 Removing of pollutants from soils and waters could be linked with both the sustainable remediation as well as sustainable energy production (Kovacs and Szemmelveisz 2017; Zheng and Shi 2017). Many strategies for the sustainable and integrated management of polluted lands should be addressed depending on several factors e.g., type of pollutants and their level, the purpose of land use after remediation, soil characterization and its topography, climate , cropping patterns and the availability of resources and their economics (El-Ramady et al. 2017;Saha et al. 2017a). Furthermore, a great debate concerning using of lands for crop food production (under growing global population) or energy crop production was and still for ages (Paschalidou et al. 2016). Therefore, a global and holistic strategy in facing the main three threats including hunger, lack of energy and pollution of environment as well as climate changes should be esta...

В обзоре рассмотрены современные подходы к экологическому нормированию качества почв, включая экологический мониторинг состояния почв и значение химических и биологических показателей в оценке качества почвы и воздействия физических факторов среды на почву. Российская система экологического нормирования, основанная на концепции предельно-допустимых концентраций (ПДК), сопоставлена с зарубежными подходами к нормированию и расчетным комплексным показателям качества почвы, в частности, c экологическим нормированием в Германии (стандарты содержания загрязняющих веществ определяются категорией объектов и характером использования земель), Нидерландах («уровни вмешательства», при превышении которых загрязнение почвы может быть квалифицировано как серьезное) и США (национальные программы сохранения природных ресурсов, природоохранная политика). Отмечены альтернативные по отношению к ПДК подходы к нормированию качества почвы (биогеохимическое и статистическое нормирование, а также экосистемный подход), рассмотрены концепции пороговых уровней и критических нагрузок и экологических рисков.
