Iron sulphate and polyaluminum chloride are commonly used in water restoration to eliminate cyanobacteria bloom and improve water quality. Nevertheless, the influence of coagulants on water organisms remains insufficiently studied. The study involves the analysis of phosphate coagulants’ impact on calcium and magnesium concentrations in the Chara hispida community. The experiments were carried out...
Contamination of water resources by pathogens due to ever increasing anthropogenic activities and the related disease burden remains a major concern of water quality globally. This study evaluated the physicochemical and microbiological quality indices of Nahoon Beach and its canal waters in South Africa over a period of 12 months (September 2014 to August 2015). Water samples were collected bi-weekly...
Land cover data, resolution, and time are among the important factors of SLUETH and similar urban growth simulation models (UGSM). Multitemporal satellite images are often used in many UGSM projects and settlement area, forest, agricultural area, highway, and temporal land cover classes can be extracted from satellite data using image processing techniques. However, land cover classes can also be...
Soil in western Jilin, China has the properties of a saline soil, seasonal frozen soil, and a dispersive soil, in which the freezing process can induce many engineering and environmental problems, including soil secondary salinization and frost heave. During the freezing process, water, heat, stress, and even solute interact with each other. Water migration plays an important role in this process...
Leaf nutrient levels are traditionally quantified by laboratory chemical analysis, which is time consuming and requires huge investment. The objective of this research is to estimate the nutrient content of groundnut leaves using an assembled visible near-infrared spectroradiometer (650-900 nm). This method is faster and requires less time and investment compared to conventional chemical analysis...
Chromophoric dissolved organic matter (CDOM) is a valuable optically active substance. This study examined the seasonal characteristics of fluorescent CDOM components in the Yinma and Songhua rivers, highly polluted watershed tributaries of the Songhua River, and a drinking water source for the city of Changchun, China. Parallel factor analysis (PARAFAC) and excitation-emission matrix (EEM) spectra...
This study combines air pollution tolerance index (APTI) and anticipated performance index (API) in order to determine the potential of trees and ornamental shrubs that are frequently growing on the roads of Quetta, Pakistan, and the campus of the University of Balochistan, in Quetta, for green belt development. Our investigation exposed that not only APTI is suitable for the fitness of trees for...
The waste generated from antibiotics as influents or effluents in important waters from the rivers over their increased usage is quickly leading to societal health problems. To avoid increased accumulation of these antibiotics and their waste matter, new methods and materials are required to solve the problems before escalation. This paper aimed at evaluating treated wastewater effluent quality of...
Nowadays, with the depletion of fossil energy and deterioration of environmental quality, solar energy is perceived to be a renewable and clean energy. While developing rapidly all over the world, solar energy is also faced with many challenges resulting from its inherent properties. In order to reduce the impact on the grid and facilitate scheduling, it is a growing problem to build a feasible model...
Groundwater chemistry in alluvia was investigated in a meander bend of the Biała Przemsza River in its middle course at Sławków in Upper Silesia, southern Poland. Pollution of groundwater induced by inflow of river water enabled recognition of relative differences in the amount of inflowing water. Biogeochemical zonation is a characteristic feature of the investigated groundwater. Inflow of river...
The objective of this study was to evaluate nutrient loss under herbaceous cover in simulated field conditions and quantify the influences of the aerial and underground parts of plants in preventing nutrient loss. The experimental settings were as follows: two herbs, i.e., alfalfa (Medicago sativa L.) and green foxtail (Setariaviridis (L.) Beauv.); four covers for each herb (0, 20-30%, 50-60%, and...
This article deals with total waste separation in the frame of a concrete region in Slovakia. The goal of the contribution is to use logistics, modelling, and simulation for the needs of total waste separation and liquidation to the way raw material and usable sources for new use in practice. Results of the simulation show that by total separation and waste recycling in the frame of the concrete analysed...
Nearly half a century has passed since the emergence of modernity’s aspects in the way of building houses in Iran. With long time passing from the life of this experience, the pattern of residential complex development did not change much compared to the beginning and its results can be seen in the design quality and satisfaction of residents from space. Clearly the expense of land as well as adequate...
Preparing novel compounds using environment-friendly protocols for plant growth has remained a major goal for plant scientists. In this research, effect of a novel plant growth promoter on sunflower (Helianthus annuus L.) was assessed hydroponically as well as in soil acclimatized plantlets at 1, 10, and 100 µM. The plants were also assessed for antioxidant enzymatic and antifungal activities. The...
The traditional extensive agricultural production model has engendered grievous pollution, not meeting the Green Development Concept proposed by China. In this context, agricultural eco-innovation is born to alleviate environmental pressure and bring a novel production mode: green agriculture. Based on the ambidexterity theory, agricultural eco-innovation should not only realize the protection of...
This research investigates the spatial and temporal trend analysis of precipitation time series. Precise predictions of precipitation trends can play an imperative role in economic growth of a country. This study examined precipitation inconsistency for 23 stations at Dongting Lake, China, over a 52-year study period (1961-2012). Statistical, nonparametric Mann- Kendall (MK) and Spearman’s rho tests...
Lanthanides are attracting increasing interest due to their technological importance and potential ecotoxicity. Knowledge of lanthanides in Polish soils is very poor, and a question arises whether the soils of former metal ore mining sites are enriched by these elements. Therefore, concentrations of six crucial lanthanides – La, Ce, Pr, Nd, Sm, and Gd – were determined in 92 soil samples collected...
Atrazine is a widely used herbicide, and because of its potential to seriously pollute soil and water resources, has attracted widespread attention. In this study, the bacterial strain LY-1 was isolated and identified as the species Arthrobacter. At present, there are many different atrazine-degrading bacteria that have been screened out, including Arthrobacter sp., Pseudomonas sp., and Shewanella...
The excessive proliferation of filamentous green algae (FGA) has been considered to be one of the important factors that result in poor growth or even a decline in submerged macrophytes. This study aims to investigate why FGA has stronger growth advantage than that of submerged macrophytes in the co-culture system. Assimilation of nitrogen and phosphorus nutrients, kinetics, and interspecific nutrient...
Potato cultivars Blaue St. Galler, Valfi, HB Red (with purple- and red-colored flesh), Irga, and Satina (with cream- and yellow-colored flesh) were treated with Trifender WP, Asahi SL, Bio-Algeen S90, and Kelpak SL. The influence of biostimulants on the P, K, Ca, Mg, and Na contents of potato skin and flesh was determined immediately after harvest and after storage. The highest content of Ca in the...
