“…This is especially evident in the hottest part of the year, which can have tragic consequences for biodiversity and ecosystem functioning. The crisis of ecological systems is manifested in the development of eutrophication and oxygen starvation, which negatively affects both aquatic macrophyte communities, especially those submerged in water, and aquatic fauna (Akinnawo 2023). The symmetric shape of the response is accepted as an axiom in the procedures of phytoindication assessment of environmental factors.…”

The study revealed the relationship between geographic and habitat estimates of the optimum of macrophyte species under temperature gradient conditions. How the estimates correlated with the point and habitat scales of the indicators was determined. The results indicate that the abundance of many species decreases sharply under extreme conditions caused by rising temperatures. The Didukh scales, after applying the ideal indicator method, provide a high level of accuracy for temperature estimation. The explanatory power of the Ellenberg scale was somewhat lower, which can be explained by the fact that this scale is "tuned" to optimal values, and under extreme conditions of factor action, the parameters of niche tolerance to which the Didukh scale is "tuned" have a limiting value. In addition, under extreme conditions, species responses to the impact of a factor often or always deviate from a symmetric model that does not take into account traditional Ellenberg scale values. At the landscape level, changes in temperature are associated with changes in oxygen, electrical conductivity and turbidity. Among the morphological characteristics of water bodies, shoreline development has the greatest influence on the temperature regime. The method of the ideal indicator, which takes into account the asymmetric distribution of species responses, has shown a high ability to indicate the temperature regime of water bodies in the Dnipro floodplain.

“…But phosphate and nitrate ions are also contaminants. The primary cause of eutrophication in lakes, reservoirs, and rivers is an overabundance of these anions [ 66 , 67 , 68 ]. Globally, elevated concentrations of these ions during the last ten years have sparked grave worries.…”

Adsorptive, catalytic, and antibacterial properties of clinoptilolite-rich tuffs (ZT) are presented here. ZT transformed into Fe-containing ZT (Fe-ZT) removes various organic and inorganic anions from water. Fe-ZT, which contains selenium, is beneficial for growing Pleurotus ostreatus mushrooms. The fungi convert inorganic Se from Fe-ZT into a more useful organically bonded form. ZT and Fe-ZT as supplements retain nitrogen and potassium in sandy, silty loam and silty clay soils. ZT shows an affinity toward toxic metal cations, which are essential for cleaning contaminated water. The adsorption of atenolol, acetylsalicylic, and salicylic acid onto M-ZT (M–Cu2+, Mn2+, Ni2+, or Zn2+) from water solutions suggests that both the natures of M and pharmaceuticals have a significant impact on the adsorption mechanism and determine the adsorption capability of the ZT. ZT is an excellent carrier for ultrafine (2–5 nm) nano oxide particles, which have been shown to have catalytic activity in different chemical processes and photodegradation reactions of organic pollutants. ZT can also be transformed into SO4-SnO2-ZT, which is catalytically active as a solid acid. M-ZT is an effective carrier of valuable bacteria. Ag-ZT possesses beneficial bactericidal activity in disinfecting water and soil remediation.

“…However, as a fertilizer for plants, ammonium (NH 4 + ) has several advantages. However, too much ammonium can cause eutrophication in water bodies, which can upset aquatic ecosystems and result in algal blooms. , Nitrate reduction may also result in the release of nitrous oxide (N 2 O), a potent greenhouse gas that contributes significantly more to global warming than carbon dioxide . Emissions of nitrogen oxide contribute to both climate change and the depletion of the ozone layer.…”

Over the decades, the rise in nitrate levels in the ecosystem has posed a serious threat to the continuous existence of humans, fauna, and flora. The deleterious effects of increasing levels of nitrates in the ecosystem have led to adverse health and environmental implications in the form of methemoglobinemia and eutrophication, respectively. Different pathways/routes for the syntheses of perovskites and their oxides were presented in this review. In recent times, electrocatalytic reduction has emerged as the most utilized technique for the conversion of nitrates into ammonia, an industrial feedstock. According to published papers, the efficiency of various perovskites and their oxides used for the electrocatalytic reduction of nitrate achieved a high Faradaic efficiency of 98%. Furthermore, studies published have shown that there is a need to improve the chemical stability of perovskites and their oxides during scale-up applications, as well as their scalability for industrial applications.
