“…Such a systematics attributed to photosynthetically induced precipitation and utilization by autotrophs is concomitant to latest studies [50]. Anthropogenic effluents are established primary sources of traces in surface waters [30] and [51]. Pertinently, such proportions exceed maximum permissible limits for drinking water but are suitable as irrigation liquid ordinarily [31], [32] and [52].…”

Water bodies act as indicators of the extent of anthropogenic interference and pressure while evolving exhibitive fluxes in intrinsic homeostasis. The ecological assessment of standard biophysicochemical variables through space-time monitoring in the region of anthro-urban intensification identifies such ecosystem responses. Sampling, preservation, preparation and analysis follow typical procedures for all the representative testers. Statistical procedures for inference of results involve Mean, Standard Deviation, Range, Correlation, Regression, Analysis of Variance (ANOVA), Cluster Analysis and Principal Components Analysis (PCA). Temperature, pH, conductivity and ionic composition of the surface waters have p<0.01 and R 2 >0.5. Total P perimeter outdid critical eutrophic index (≤ 0.05 mgL-1) but nitrate N persisted underneath it (≤ 0.5 mgL-1) ordinarily. Elevated nutrient levels reflect multiple human origins and catchment interventions. Priority pollutants (As, Cd, Cr, Cu, Pb, Ni and Se) remained below chronic levels with exception of Fe and Zn exceeding maximum permissible limits for irrigation purpose of the water. Major elements in surface sediments are Si> Ca> Mg> K> Na> P> S> Cl besides the micro and trace ones follow as Fe> Al> Zn> Mn> Cu> Cr> Ni> Co> As> Sn> Pb> Cd. Sediments correspond to calcite catchment character to conform their sink-selves. The peak biomass values as gm-2 are 880.2 in case of Myriophyllum aquaticum, 678.4 in Nelumbo nucifera, 182.4 in Ceratophyllum demersum and 45 in Salvinia natans. The upgraded biomass configuration coincides with supplementary bioconcentration. C/N <10 implies low decomposition rates and autochthonous origin of organic matter. A semidrainage type of flushing hydrology ensures low basin holding time for self-reclaimed nutrient balance. Sediment dredging is beneficial for internal nutrient deloading only after external inputs are curtailed. Biological scavenging and biogenic calcification together lower the bioavailability of nutrients and toxics. Hence, the systemic insitu pliability can prevail till exsitu lacustrine management fortifies euoecism to evade detrimental dysoecism.

“…Emerging contaminants can be increasingly associated with the waste and wastewater resulting from industrial, agricultural, or municipal activities that create environmental and public health problems in many locations around the world [3][4][5]. In addition to toxic water pollution with metals, human activities can lead to the acidification and eutrophication of the aquatic environment, which increases the bioavailability of metals and worsens the oxygen regime of the habitat environment [13].…”

Metals are dispersed in natural environments, particularly in the aquatic environment, and accumulate, causing adverse effects on aquatic life. Moreover, chronic polymetallic water pollution is a common problem, and the biological effects of exposure to complex mixtures of metals are the most difficult to interpret. In this review, metal toxicity is examined with a focus on its impact on energy metabolism. Mechanisms regulating adenosine triphosphate (ATP) production and reactive oxygen species (ROS) emission are considered in their dual roles in the development of cytotoxicity and cytoprotection, and mitochondria may become target organelles of metal toxicity when the transmembrane potential is reduced below its phosphorylation level. One of the main consequences of metal toxicity is additional energy costs, and the metabolic load can lead to the disruption of oxidative metabolism and enhanced anaerobiosis.

“…NO2 is emitted into the atmosphere as a result of anthropogenic activities (e.g., combustion of fossil fuels and biomass burning) and natural processes (e.g., microbiological processes in soil, ring, and lightning) (He et al, 2020;Ogen, 2020). CO is also a result of the incomplete combustion of carbon-containing fuels, such as oil and natural gas (Karimi et al, 2016;Moiseenko et al, 2016). Therefore, the NO 2 and CO products derived from Sentinel-5P data collected between March 11 -April 8 in 2019, 2020, and 2020 were used in this study (Table 1).…”

The end of the Persian year (March 2020) coincided with its global pandemic, which led to quarantine and lockdown in Iran. Many studies have shown that with the spread of this disease and the decline of industrial activities, environmental pollutants were drastically reduced. Among these pollutants, Nitrogen Dioxide (NO2) and Carbon Monoxide (CO) are widely caused by anthropogenic and industrial activities. In this study, the changes of these pollutants in Iran and its four metropolises (i.e., Tehran, Mashhad, Isfahan, and Tabriz) in three time periods from March 11 to April 8 of 2019, 2020, and 2021 were investigated. To this end, time-series of the Sentinel-5P TROPOMI and in-situ data within the Google Earth Engine (GEE) cloud-based platform were employed. It was observed that the results obtained from the satellite data were in agreement with the in-situ data (average correlation coefficient =0.7). Moreover, the concentration of NO 2 and CO pollutants in 2020 was 5% lower than in 2019, indicating the observance of quarantine rules as well as people’s initial fear of the Coronavirus. Contrarily, these pollutants in 2021 were higher than those in 2020 by 5%, which could be due to high vehicle traffic and the lack of serious policy by the government to ban urban and interurban traffic. Furthermore, the increase of these pollutants in 2021 was followed by an increase in the deaths caused by Covid-19 and triggering the fourth peak in the Covid-19 cases, signifying a link between exposure to air pollution and Covid-19 mortality in Iran.
