Top Research Papers on Water Pollution

It was found that the biosorption of complex mixtures of pollutants on fungal pellets is scarcely studied, as well as the interfering effect of anions commonly found in water and wastewater, and there is a lack of research with real wastewater and at pilot and large scale.

Water demand continues to increase, while its availability was increasingly limited due to pollution. Therefore, the issue of legal sanction in the management of water resources was interesting to be examined because of the void of norm related to the sanction of administrative, civil and criminal sanction in Article 87-120 of Act Number 32 of 2009. So, this research was qualified into normative legal research with legal material from result of library research. The type of administrative legal sanctions were more effectively applied to protect water resources from pollution. Administrative Le...

Chemical analysis of water samples from Pravara river basin and Pravara left bank canal shows that the water is characterized by alkaline earth. Water samples from thirteen spots of down stream from Bhandara to Babhaleshwar were collected for analysis at an interval of ten kilometers. The results show that the physico-chemical characteristic of water changes to downstream from Bhandara to Babhaleshwar due to human activities.

In response to an alleged Communist coup in Indonesia on 1 October 1965, ambassadors Sir Keith Shann (Australia), Sir Andrew Gilchrist (United Kingdom), and Marshall Green (United States) initiated anti-Communist propaganda campaigns. In conjunction with the Indonesian army, these campaigns helped to underpin the rationale for widespread, army-coordinated anti-Communist repression throughout Indonesia. Through a careful re-examination of Australian archival materials regarding Indonesia between October 1965 and February 1966, this article provides a detailed, transnational chronology of propag...

Water is an essential part of every living thing on this plant. It is essential in such a way that every biotic function relies on it. Water is used in agriculture, consumption and fishery. For plants, it is necessary for photosynthesis, their food-making process, while for human and animals; it is necessary for digestion, blood circulation, temperature modulation and many others. It is therefore impossible for life to continue without it. Though the world is composed entirely of water, almost three-fourths of earth, only a small fraction of the entirety of it is available for consumption. Acc...

The occurance of emerging contaminants in water had become an environmental concern since global climate change is causing water to become a scarce resource globally. Veternary antibiotic sulfamethoxazole (SMX) is one of emerging pollutants of interest in this study. The main concern with the presence of antibiotics in aquatic environment is that they can provoke antibiotic resistance which bear ecological and human health risks. Hence, investigations on the adsorption capacity of zeolite Y on SMX in the presence of caffeic acid (CA) and vanillin (VNL) were carried out.The experiments were con...

The environmental dimension is a key factor in a city sustainable development and must be incorporated in the planning process of the dense and complex urban areas. Nowadays particular emphasis is given to the problems of water, soil and air pollution in urban context. However, those evaluations not always motivate the indispensable environmental and social conscience to mitigate the origin of the pollution problems. So, in some cases the public health is in risk, mainly when the presence of preoccupying levels of contamination can be identified in soils and plants. In Portuguese cities, and a...

ABSTRACT Agriculture is an important cause of multiple pollutants in water. With population growth and increasing food demand, more nutrients, plastics, pesticides, pathogens and antibiotics are expected to enter water systems in the 21st century. As a result, water science has been shifting from single-pollutant to multi-pollutant perspectives for large-scale water quality assessments. This perspective paper summarizes and discusses four main highlights related to water pollution and agriculture from the multi-pollutant perspective. These highlights reveal the spatial and temporal distributio...

There is growing evidence that the Nation's ground water is contaminated by a variety of sources. These include unprotected industrial, municipal, and radioactive disposal sites, petroleum exploration and mining activities, agricultural operations such as insecticide spraying, high de-icing salts and others. As of March 1980, more than 8000 chemical tests have been performed on well water, with chlorinated organic solvents found most frequently. Because 100 million Americans may be threatened by unfit drinking water, EPA has developed a new ground water strategy. It will enlist the help of Sta...

A chemical that is toxic to one animal may also be toxic to other forms of animal life. Although it might take a larger dose of pesticides to harm humans than pests, such as insects, many pesticides are still toxic to humans. The doses needed to kill a pest might not kill us, but may still harm us. Many pesticides classified as herbicides are designed to target plant pests. The exceptions to this are broad spectrum herbicides that are designed to kill a wide variety of plants. An herbicide that is specific to one or more species of plants does not ensure that it is safe to enter the water syst...

This chapter critically examines English, as well as selected European Union, laws that regulate the interlinked environmental challenges of protecting the quality and quantity of water courses. It deals with legal rules seeking to prevent and limit the pollution of rivers and other inland surface waters, such as lakes, as well as coastal areas and groundwater. One of the key challenges for water pollution law is to evolve into a more holistic, coherent, and integrated pollution control regime. In discussing this challenge, the chapter refers to and critiques recent interesting attempts to dev...

The attempt by certain jurisdictions to preserve a rural lifestyle by means of farmland preservation may produce some unwanted side effects, such as polluted water supplies. While there are many excellent and important reasons to preserve high-quality agricultural land for food production, efforts to retain or encourage agricultural activities in areas experiencing rapid population growth may produce some serious environmental problems. For the entire post-WW II period the United States has experienced almost continuous suburban sprawl. Many incorporated areas, experiencing rapid developmen...

Water is used in agriculture for irrigation as well as for drinking water for man and beast. The pollution of water with salts, plant nutrients, organic material, pathogens and parasites, as well as toxic components, decreases its value for agricultural purposes. The rapid development of and the population growth in South Africa will increase water pollution, and agriculture will thus be influenced. Agriculture will also have to intensify in the future to meet the expected increased demand for food; the role of agriculture as a water polluter will thus also increase. South African agriculturis...

Water pollution is the contamination of natural water bodies by chemical, physical, radioactive or pathogenic microbial substances. Adverse alteration of water quality presently produces large scale illness and deaths, accounting for approximately 50 million deaths per year worldwide, most of these deaths occurring in Africa and Asia. In China, for example, about 75 percent of the population (or 1.1 billion people) are without access to unpolluted drinking water, according to China's own standards.[1] Widespread consequences of water pollution upon ecosystems include species mortality, biodive...

The analysis of organic pollutants in water is a subject of very large scope that can include a description of all analytical techniques known at this moment. A large number of papers with respect to the field have been published in the last 20 years. Many reviews are written on minor aspects of this subject. In Europe, the Commission of the European Community started a project entitled “Analysis of Organic Micropollutants in Water” with the aim of coordinating all relevant research in this field in the participating countries. In 1981, they organized a symposium with review papers in areas su...

Introduction Water in Zambia, is not equally provided to everyone. For example, out of the population of about 13 million in Zambia, about 5 million do not have access to clean water. This also applies to sanitation in Zambia; about 7 million of Zambians do not have access to sanitation facilities. In Zambia, water pollution has been seriously affecting the life of humans, plants as well as animals. The eco-system of rivers, streams and lakes is also getting deteriorated due to the contamination of water, through various sources. This condition also leads to the outbreak of numerous diseases, ...

A B S T R A C T The purpose of this paper is to describe and analysis of ground water pollution. When many people think of a water source, they think of lakes, rivers and streams; in other words, surface water. However, of all of the usable freshwater in the world, approximately 97 percent of it is ground water. Scientists agree that there is a lot of water under the earth’s surface! The crucial role groundwater plays as a decentralized source of drinking water for millions rural and urban families cannot be overstated. According to some estimates, it accounts for nearly 80 per cent of the rur...

From personal experience the writer came to a realization of some of the difficulties in obtaining satisfactory sources of water supply for many of the smaller and some of the larger cities and towns in the state. There are many settlements in Ohio which have grown into populous villages and cities by reason of local conditions which have affected their prosperity, and when they have reached the size and dignity of a large village, or a small city, and sought to obtain the usual sanitary conveniences now considered as essentials of populated centers, have found that there was no convenient sou...

The 99th General Assembly's Amended Substitute Senate Bill No. 62, commonly called the "Deddens' Act", represents the first attempt to establish a comprehensive state program of water pollution control in Ohio.

A literature review dealing with the process of eutrophication with respect to the sources and transport of pollutants is presented. Topics include the mathematical modeling of nutrient loading, eutrophication, and aquatic ecosystems. Biological and environmental indicators of eutrophication are reviewed, and the interactions between various chemical and biological pollutants are considered. Several lake management projects are discussed. (KRM)

The surface water pollution in rivers, lakes, reservoirs, coastal areas, and other surface water resources may occur mainly because of point-source pollution and nonpoint-source pollution. The term point-source pollution refers to pollutants discharged from one discrete location or point, such as an industry or municipal wastewater treatment plant, to surface water resources (Fig. 1). The effluent out-fall from factories, refineries, waste treatment plants, etc. emits fluids of varying quality directly into surface waters. The term nonpoint-source pollution refers to the discharge of po...

This article describes a Tulasi Srinivas' piece in The Revealer on how environmental pollution threatens sacred practice in India.

I am writing in reference to an article by Leonard B. Dworsky in the August issue of EOS dealing with what the author feels are the necessary steps toward an effective and credible program of water pollution control. That public expectations need to be adjusted to real world solutions can hardly be denied. The general public is all too often led to believe that there is an instant solution to every problem, and many self-appointed ‘experts’ have led the public to believe that this is also true of pollution. But even among those who realize effective pollution control requires a dedicated, c...

The demand for clean water for industry and for domestic supply is increasing yearly. Many readily accessible supplies are fuh'y exploited and water authorities are now having to consider hitherto-polluted rivers as possible sources for future demand. To meet the demand for clean water and for cleaner rivers which receive the waste from the consumers, a massive amount of expenditure will be required from central and local government and from industry for new water-treatment plants. The legislation covering river pollution and waste-water disposal in Scotland is described, and the particular pr...

Water pollution regulations and the types and sources of water pollution common to a ``typical'' cement plant are discussed. With the exception of the problem of totally dissolved solids in ``process'' water, solutions to most of the other water pollution problems common to a cement plant have been known. A solution to the problem of totally dissolved solids in ``process'' water is offered in this paper.

A parameter of a water body e.g. acidity, turbidity or temperature is continuously monitored by sensors to provide an output signal which actuates a H2O sampler when the signal falls outside a certain range.

Thermal pollution occurs as a natural process required by the Second Law of Thermodynamics for any thermodynamic cycle to operate. Water is often used as a cooling medium, which is heated and returned to the environment warmer than when it started. The problem is to reduce the impact this has on the environment and to reduce the total amount of heat rejected. The amount of head rejected to water bodies can be reduced by conservation, using alternated disposal methods such and cooling towers, and more efficient plants and machines. The impact of heat rejection can be reduced by limiting the vol...
