Web-mapping of environmental pollution of the surface waters of the Lviv region

Little is known about the occurrence of emerging pollutants (EPs) in waters in the Middle East and North Africa (MENA) region despite the extensive use of low-quality water there. Available data dealing with the sources, occurrence and removal of EPs within the MENA region in different categories of water is collected, presented and analyzed in this literature review. According to the collected database, the occurrence and removal efficiency of EPs in the water matrix in the MENA region is available, respectively, for 13 and six countries of the 18 in total; no available data is registered for the rest. Altogether, 290 EPs have been observed in different water matrices across the MENA countries, stemming mainly from industrial effluents, agricultural practices, and discharge or reuse of treated wastewater (TWW). Pharmaceutical compounds figure among the most frequently reported compounds in wastewater, TWW, surface water, and drinking water. Nevertheless, pesticides are the most frequently detected pollutants in groundwater. Worryingly, 57 cases of EPs have been reported in different fresh and drinking waters, exceeding World Health Organization (WHO) and European Commission (EC) thresholds. Overall, pharmaceuticals, organic compounds, and pesticides are the most concerning EP groups. The review revealed the ineffectiveness of treatment processes used in the region to remove EPs. Negative removals of some EPs such as carbamazepine, erythromycin, and sulfamethoxazole were recorded, suggesting their possible accumulation or release during treatment. This underlines the need to set in place and strengthen control measures, treatment procedures, standards, and policies for such pollutants in the region.

Comprehensive analysis of water use and pollution management plays an important role in regional water security and sustainable socio-economic development. This study applies the environmental Kuznets curve (EKC), Gini index and elasticity coefficient methods to conduct an investigation of industrial and domestic water use and pollution management in Shandong. The results show that industrial water pollution generally displayed a coordinated relationship with socio-economic development, while an uncoordinated relationship occurred between domestic water pollution and socio-economic development. Meanwhile, the Gini index between domestic water use and population in 2017 (0.101) was superior to that of 2003 (0.165), and the Gini index of industrial water use and second industry output in 2017 (0.273) was better than that of 2003 (0.292), indicating that the allocation and equity of domestic and industrial water use in Shandong kept to a good development trend. Additionally, the industrial effect is better than the domestic effect in terms of the control of wastewater emissions and the governance of typical pollutants in wastewater. Accordingly, domestic water pollution has gradually become one of the major sources of water pollution, and the allocation of industrial and domestic water use has room to improve further in Shandong. Conjunctive use of the aforementioned three methods provides an approach to investigate the integrated management of water use and water pollution control from multiple angles.

Organic pollution poses a significant threat to water security, making the monitoring of organic pollutants in water environments essential for the protection of water resources. Remote sensing technology, with its wide coverage, continuous monitoring capability, and cost-efficiency, overcomes the limitations of traditional methods, which are often time-consuming, labor-intensive, and spatially restricted. As a result, it has become an effective tool for monitoring organic pollution in water environments. In this study, we propose a physically constrained remote sensing algorithm for the quantitative estimation of organic pollution in inland waters based on radiative transfer theory. The algorithm was applied to the Feilaixia Basin using Sentinel-2 data. Accuracy assessment results demonstrate good performance in the quantitative assessment of organic pollution, with a coefficient of determination (R2) of 0.79, a mean absolute percentage error (MAPE) of 13.03%, and a root mean square error (RMSE) of 0.39 mg/L. Additionally, a seasonal variation map of organic pollutant concentrations in the Feilaixia Basin was generated, providing valuable scientific support for regional water quality monitoring and management.

Water shortage and water pollution is become to a more serious problem in the world especially in developing country.Water pollution is mainly due to a large number of emissions from industrial wastewater, agricultural drainage, and urban wastewater to rivers, lakes and soil which is making surface water and groundwater quality deterioration.This water shortage is aggravated by the exacerbated water quality and thus to influence human health and society economy development [1] .In order to conserve water resources, prevent water pollution, and improve sustainable development of water environment and aquaculture production, water quality monitoring and control in dynamically and regularity is become more and more important.Water quality monitoring and control is not only able to understand the water quality changes and pollution migration patterns, but also provide scientific and reasonable technical support for water resources integrated planning, water environment assessment, water treatment and conservation technology [2] .Therefore, water quality monitoring is essential tool and basis foundation in water resource management and water pollution supervision and control for government administration.Water quality monitoring of different water sources is difficult because of the intricate components and its mutual interference and thus depended mainly on chemical analysis and instrumental analysis.According to geochemistry, geographical and regional differences of water environment or water pollution, water quality monitoring is always conducted in instrument station and to construct a monitoring network for water quality management, assessment and planning via short-term monitoring, long-term monitoring, emergency monitoring, and dynamic monitoring [3,4] .To supplement the instrument stations in laboratory level, water quality monitoring vehicle or shipping using flow sampling and online monitoring is used for water pollution tracking or iterative detection.Recent years, water quality dynamic monitoring using online sensors is applied for various applications and increasing with promoting commercialization of ions selective electrodes.Since 1960, local, continents and federal agencies in the United State began to collect water quality data and gradually getting a unified specification data to establish STORET water quality system.20 years later, the STORET water quality system is used to provide the water www.intechopen.comRecent Developments in Mobile Communications -A Multidisciplinary Approach 252 quality scientific data and water pollution management support for federal, state and local water authorities [5] .Water quality file analysis system WAP2 (Water Archive Phase 2) is developed in UK after STORET water quality system constructed.WAP2 system is focusing on relationship between the hydrological cycle and impact of human activities, and described in detail for hydrology, meteorology, water supply, drainage, wastewater treatment, industrial, and water quality [6,7] .Compared to advanced countries, water quality monitoring technology in developing countries is developed and applied from 1980s and almost conducted by regional or local government.the national water quality monitoring network is still not established such as China and Indian, because of the different sampling methods and expensive instrument import form the United States and Germany [8] .Water quality dynamic monitoring is integrated from chemical analysis, computer, sensing, and communication technologies for simultaneous detection of several water quality parameters, mass data processing, and automatic water treatment in designated regions.The sampling method and monitored data will be basis foundation to represent water quality for in the regional water environment.On the other hand, suitable sample distribution and contrast handy chemical analysis are important in water quality dynamic monitoring especially for rivers with serious floating debris and soil erosion [9,10] .Therefore, automatic cleaning, calibration, diagnostics, and alarm functions, data remote transmission, and networking construction will be required in water quality dynamic monitoring.This chapter is focus on water quality sensors based on ion specific electrodes, water quality dynamic monitoring system based on web-server-embedded technology and its application in rivers and freshwater detection, aquaculture production and hydroponic plant production.www.intechopen.com

Fresh water is needed worldwide for agricultural and economic sectors, but also for nature. However, the water demand continues to increase due to economic growth, urbanization and increased food production, while water availability decreases. Thereby, weather extremes are expected to increase and occur more frequently. As a result, there is an increased mismatch between water demand and water supply. Historically, Dutch agricultural fields were drained to remove water in wet periods. Nowadays, drainage systems are increasingly being modified to controlled drainage with subirrigation (CDSI) systems to i) discharge water when needed and ii) retain water and iii) recharge water when possible. However, the implementation of CDSI on a local scale alters several water balance components. CDSI positively affects transpiration for crop growth, increases drainage to the surface water and increases downward seepage, i.e. groundwater recharge. However, CDSI also requires surface water, which is not infinitely available. It is, therefore, important for regional water management authorities to understand how the field scale measure CDSI propagates through the regional water system in order to estimate if sufficient surface water is available to scale up CDSI to other fields.A system dynamics model (SDM) approach is used to get insight into the hydrological effects of upscaling CDSI. SDM’s are widely used to understand non-linear behavior of complex systems with feedback-driven components in order to make policy decisions for example. Our SDM is a simple, but comprehensive model based on four field experiments conducted in the Netherlands and a detailed calibrated Soil, Water, Atmosphere and Plant (SWAP) model. The results show that the SDM takes account of different feedback loops that determine the possibilities of upscaling CDSI. This includes an increase in drainage to the ditch, but at the same time, subirrigation lowers the ditch level, which in turn reduces drainage to the ditch. The results further show 3 CDSI possibilities: i) sufficient surface water is available to scale up CDSI to 20 % of the area, ii) sufficient surface water is available, but surface water levels decline when scaling up CDSI between 20 – 30 %, iii) insufficient surface water is available to scale up CDSI between 30 – 100 % as the surface water runs dry. In the latter case, hydrological characteristics (regional surface water inflow, regional weir height and minimal surface water level) can be adapted to increase the regional water availability and therefore allow further CDSI upscaling. We show that a SDM is a useful method for an initial design of how a local measure affects the regional water management, which gives the regional management authority insight in the hydrological effects of upscaling measures and therefore supports the conversations between policy makers and stakeholders (e.g. farmers).

Impacts of soil and water pollution on food safety and health risks in China

Urban pharmaceutical industries are responsible for high intensity emissions of water pollutants. The regional water pollutant emission standards vary greatly throughout the Yangtze River Delta Urban Agglomeration (YRDUA) in China, which, to some extent, results in increased risks and hidden dangers to regional water environment safety, especially water quality. Under the national strategy of Yangtze River Delta ecological and green integration development, a unified standard of water pollutant emissions should be integrated into the integration development process, but differences between characteristic items, concentration limits, and conditions among four local standards of water pollutant emission have become a key influencing factor in their integration in industry and in green transformation. When comparing the water pollutant emission standards of the biopharmaceutical industry in three provinces and one municipality of the YRDUA, the factors influencing integration were determined and caused by the main differences in local water pollutant emission standards, namely, the race to the bottom of the biopharmaceutical industry, the inconsistency of environmental protection regulation law, and transboundary water pollution risks. From the perspective of urban water quality safety, we propose the following strategies for promoting the integration of water pollutant emission standards in the YRDUA: (1) increasing government funding for local water pollution governance and encouraging industries to adopt the third-party governance model for pollution control in the YRDUA; (2) unifying water pollutant emission standards and environmental law enforcement standards in the YRDUA with a mechanism involving shared economic responsibility; and (3) establishing a platform for sharing data and governance performance for the emission of water pollutants in the YRDUA.

Water is the most basic need for all living things on Earth. The abundance of water on Earth makes humans indifferent to the efficient use of water, including human activities, which are said to cause increasing pollutant loads in surface waters. The western part of Java, consisting of DKI Jakarta, West Java and Banten, has the highest population pressure in all parts of Indonesia. This has led to a decrease in the environment's carrying capacity, especially in the region's water resources. Agricultural and industrial activities and household activities cause decreasing water availability in quantity and reducing water quality. This has become a trigger for water scarcity both in quantity and quality. Based on the data, the western part of Java Island has rivers with critical status. In this study, researchers will analyze water availability, water pollution problems, and challenges in overcoming water pollution, especially in the western part of Java Island. This study used a qualitative method by conducting a literature review. In overcoming water pollution, serious efforts need to be made, including increasing community participation in the manufacture of household-scale WWTPs, limiting the use of pesticides in agricultural activities, and improving water quality by improving land cover in the upstream area and increasing water absorption in urban areas.

During last 30 years in Izmir area (Aegean Sea basin), an industrial growth caused serious environmental contamination of both waters and landscapes. Coastal water pollution caused by the increased industrialization, particularly of Izmir Bay, has been detected recently. Urbanization has impressive rates in Turkey, increasing from 18.5% in 1950 until 62% in 2000. Such uncontrolled urban expansion leads to gradual decrease of fertile landscapes and agricultural areas along the Aegean coasts and increases the pollution of waters. The chemical contamination in Izmir bay (mercury originating from Gediz River and inactive mining sites in Karaburun Peninsula) comes to the shelf waters. Consequently, the detected content of mercury in selected plankton organisms exceeds the acceptable standards as a maximal limit in living creatures. As a result, it has been reported that pollution in Izmir’s overall surface water, chemical quality of groundwaters, lakes and rivers has deteriorated. An increase of water contamination caused by the industrial discharge posed a serious threat to environmental conditions in Izmir area. The ecological threats of water pollution has been documented by many reports, manuscripts and articles reviewed in this paper.

Concerns regarding the management of water and air pollution in border regions – such as the California‐Mexico Border, is an old issue, which has bubbled up to its current crisis situation. Health and safety disasters, stemming from water pollution on both sides of the border mount as do related costs to local financially‐strapped communities in California. One such impacted community is Imperial County, California, which must deal with the consequences stemming from the “dirtiest river in the United States”. This refers to The New River which enters the US through Mexico. While NAFTA has promoted the growth of globalized companies and industries in the region, progress has added to pollution. Regulation is far from evenly matched in the two countries. To manage negative spillover effects from globalism across borders, the time has come for development of new administrative law, with strict penalties for violators. This article uses the impact of pollution from The New River to discuss the hollowing of our nation‐state’s democratically‐derived mandate against pollution. It also raises the question of whether we have the stomach to push for new administrative law and risk multinational flight to other more accommodating regions, or live with the status quo and its serious human and environmental consequences.

Driving forces and variation in water footprint before and after the COVID-19 lockdown in Fujian Province of China

Water pollution has emerged as the biggest threat to the sustenance of human civilization and the environment. With the increase in rapid industrialization and urbanization, there is a considerable increase in the influx of complex and diverse pollutants in water bodies. Hence continuous and efficient monitoring is required to detect the pollutants in the aquatic environment. Either preventing or detecting and subsequent elimination of these pollutants is of utmost importance for the health of the aquatic ecosystem. Biosensors have proved to be efficient in detecting these pollutants in a better way as compared to other conventional methods. Sensors are devices that have the ability to detect changes in the physical, chemical, or biological domains and produce a signal that can be measured. The distinguisher element in it minimizes noise caused by other components in the analyte mixture by being able to detect a specific analyte or set of analytes. This current review is focused on the role of biosensors in detecting metallic pollutants in water bodies. It also discusses the process of remediation of metallic pollutants in the aquatic environment.

Heavy metal pollution in surface water is a global environmental problem. This study analyzed the trends, health risks, and sources of eight dissolved heavy metal species in river and lake water across five continents (Africa, Asia, Europe, North America, and South America; Oceania was excluded owing to a lack of data) for the period 1970-2017. We wanted to assess the effects of various implemented countermeasures to pollution and to determine those that could be adopted worldwide. Collectively, the water system showed increasing trends for Cd, Cr, Cu, Ni, Mn, and Fe and decreasing trends for Pb and Zn. The mean dissolved concentrations of most heavy metals were highest in Asia and lowest in Europe. Most heavy metals had low non-carcinogenic risks over this period. The cancer risks associated with Pb were lower than the hazardous level on all five continents over the five decades, whereas the cancer risks related to Cr exceeded the hazardous level in the 1970s, 2000s, and 2010s, and in Africa, Asia, and North America over the entire period. Mining and manufacturing were consistently found to be critical sources of metal pollution from 1970 to 2017. However, the heavy metal sources differed significantly by continent, with waste discharge and rock weathering dominant in Africa; mining and manufacturing, along with rock weathering, are dominant in Asia and South America; fertilizer and pesticide use, along with rock weathering, are dominant in North America; and mining and manufacturing, waste discharge, and rock weathering are dominant in Europe. Global trends in the metal loadings in water and in relevant pollution-control measures suggest that countermeasures in Europe have successfully controlled heavy metal pollution. The successful measures include implementing rigorous standards for metal emissions, limiting the metal concentrations in products, and rigorously treating metal-contaminated waste. Therefore, the measures implemented in Europe should be extended worldwide to treat heavy metal pollution in water.
