ABSTRACT: Visual pollution is the term given to unattractive or unnatural visual elements of a vista, a landscape, or any other thing that a person might not want to look at. Commonly cited examples are houses, automobiles, traffic signs, road signs, highways, roadways, billboards, litter, graffiti, overhead power lines, utility, contrails, skywriting, buildings, weeds and advertisements. These are ually considered visual pollution when placed in a landscape or surrounding where the person seeing them things that they do not fit. For example big billboards n a countryside village or graffiti on an old eighteenth century house can be seen as visual pollution. KEY WORDS: Visual pollution, poisonous chemicals, heavy metals, toxic substances. INTRODUCTION: The word pollution implies a negative impact on our environment. When a reference is made to polluting the environment we commonly think of land, air and water pollution. The types of images we conger up are the dumping of chemicals into our environment, toxic smoke being released into the air, litter lining our streets and parks, poisonous chemicals following into our ponds and rivers, toxins and heavy metals penetrating our ground water supplies.

  • Understanding Pollution: Visual Pollution Is More Than Just a Bad
    Understanding Pollution: Visual Pollution Is More than Just a Bad View Pollution doesn’t always have to be about earth shattering issues that will determine the fate of the planet. Sometimes, pollution is about the little things that determine whether we have a good day or a bad day. I am speaking specifically of what is known as visual pollution. I remember as a kid walking out the backdoor of my house, and seeing nothing but woods as far as my little eyes could see. It was beautiful, and I have dozens if not hundreds of memories of exploring those woods with a wide eyed wonder. Then, when I was a teenager, I walked out my backdoor, and those woods were gone. They were replaced by construction sites as dozens of new homes were being built. Far be it from me to deny anyone a home, but I never had the same feeling of serenity walking out and seeing those construction sites, and later houses, as I did those woods. Now, you may be thinking “boohoo, cry me a river.” I understand, but visual pollution isn’t simply just a desire for an aesthetically pleasing view. The term visual pollution “encompasses different visually unattractive elements of a certain landscape. This type of pollution doesn't have to be necessarily connected to environmental damage, and is in fact more an aesthetic issue that can vary from one person to other.”i Visual pollution can encompass things from landfills to advertising billboards, telephone and power lines, street signs, graffiti, traffic lights, and really anything that someone might consider an eyesore.ii Visual pollution is also connected to most other forms of pollution.

Pollution can include chemicals such as oil, CFC’s, radioactive compounds or even energy like heat, light and sound. These contaminants are referred to as pollutants. There are many different kinds of pollution and three keyy ones are outlined below. Air Pollution This is when particulates or other harmful materials are released into the atmosphere. Our atmosphere is vital to the survival of all living things and is what makes our planet habitable. It has been estimated that seven million people die each year from air pollution related illness and disease. As well as death, air pollution also causes breathing diffi culties, heart disease, asthma, stroke and lung cancer. Air pollution also affects plants and animal growth, and can destroy habitats through the production of acid rain. Smog is a combination of soot, smoke and sulfur dioxide mainly from vehicles, burning fossil fuels and factory fumes. Not only this but it can form ground level ozone which is quite toxic to all living organisms. This combination of emissions creates a thick smoky fog that covers cities and contributes to the major health problems stated above.

However, the subjectivity and complexity of assessing visual pollution in urban settings remain a challenge, especially given the lack of robust and reliable methods for quantification of visual pollution. This paper presents a novel systematic approach for the development of a robust Visual Pollution Assessment (VPA) tool. A key feature of our methodology is explicit and systematic incorporation of expert and public opinion for listing and ranking Visual Pollution Objects (VPOs).

  • Measuring Visual Pollution with Tangential View Landscape Metrics
    land Article Chaos in Motion: Measuring Visual Pollution with Tangential View Landscape Metrics Szymon Chmielewski Department of Grassland and Landscape Studies, University of Life Sciences in Lublin, Akademicka 15 St., 20-950 Lublin, Poland; [email protected] Received: 21 November 2020; Accepted: 10 December 2020; Published: 12 December 2020 Abstract: Visual pollution (VP) in the form of outdoor advertisements (OA) is a threat to landscape physiognomy. Despite their proven usefulness in landscape aesthetic studies, landscape metrics have not yet been applied to address the phenomenon of VP. To fill this knowledge gap, a methodological framework for the measurement of VP using tangential view landscape metrics is proposed, which is accompanied by statistically significant proofs. Raster products derived from aerial laser scanning data were used to characterize two study areas with different topographic conditions in the city of Lublin, East Poland. The visibility of the cityscape in motion was simulated through viewshed measurements taken at equal intervals in the forwards and backwards directions along pedestrian walkways. The scrutinized tangential view landscape metrics (visible area, maximum visible distance, skyline, Shannon depth, view depth line) was the object of a two-fold interpretation wherein the spatial occurrence of VP as well as its impacts on the visual landscape character (VLC) were examined. The visible area metrics were found to be highly sensitive VP indicators. The maximum visible distance metrics provided evidence for the destructive effect of OA on view corridors. The Shannon depth and depth line metrics were not found to be statistically significant indicators of VP.Results from directional viewshed modelling indicate that distortion in the analyzed cityscape physiognomy depends on the view direction.

National Management Measures to Control Nonpoint Source Pollution from Urban Areas Management Measure 9: Pollution Prevention November 2005 Management Measure 9: Pollution Prevention MANAGEMENT MEASURE 9 POLLUTION PREVENTION 9.1 Management Measure Implement pollution prevention and education programs to reduce nonpoint source pollutants generated from the following activities: — The improper storage, use, and disposal of household chemicals, including automobile fluids, pesticides, paints, solvents, etc.; — Lawn and garden activities, including the improper application and disposal of lawn and garden care products, and the disposal of leaves and yard trimmings; — Turf management on golf courses, parks, and recreational areas; — Commercial activities, including parking lots and gas stations; — Improper disposal of pet wastes; and — Activities that generate trash. 9.2 Management Measure Description and Selection 9.2.1 Description This management measure is intended to prevent or reduce nonpoint source pollutant loadings generated from a variety of activities within urban areas. Everyday activities of citizens, municipal employees, and businesses have the potential to contribute to nonpoint source pollutant loadings. These activities include improper use and disposal of household chemicals, lawn and garden maintenance, turf grass management, operation and maintenance of diesel and gasoline vehicles, illicit discharges to urban runoff conveyances, commercial activities, and improper pet waste disposal. Reducing pollutant generation can decrease adverse water quality impacts from these sources.

It must be controlled to maintain sustainable agricultural systems and the main mechanisms of control are stabilising catchment processes and reducing nutrient output. Eutrophication can be defined as 'the nutrient enrichment of waters which results in the stimulation of an array of symptomatic changes, among which increased production of algae and macrophytes, deterioration of water quality and other symptomatic changes, are found to be undesirable and interfere with water uses' (OECD 1982). The word eutrophic is a Greek word that means 'well fed'.

  • Environmental Pollution and Ways to Reduce Contamination with Use of Environmental Engineering Techniques in Metropolises of Developing Countries Pedram Saremi
    International Journal of Environment, Agriculture and Biotechnology, 5(3) May-Jun, 2020 | Available: https://ijeab.com/ Environmental Pollution and ways to Reduce Contamination with use of Environmental Engineering Techniques in Metropolises of Developing Countries Pedram Saremi Master Student in Transportation Engineering Civil Engineering Dept. Sapienza University, Rome, Italy Abstract— Environmental pollution comes from a variety of sources. With the advancement of human civilization and the development of technology and population growth, now the world is facing a problem called pollution in air and land, which threatens the lives of the world's inhabitants. One of the current crises is environmental pollution, which mostly is considered to be the result of the technology, industrial and agricultural development expansion. If there is no control over the Progressive and exponential growth of this phenomenon, we will face an environmental catastrophe and disaster. In a simple definition, environmental pollution is any change in the Features of environmental components, i.e. water, soil, air, etc., so that it is impossible to use them optimally and endangers the lives of living organisms directly or indirectly. Access to healthy and adequate food, drinking water and clean air is the most obvious right of all humans, and the production and provision of these needs for citizens is an inherent duty of all governments. On the other hand, preserving the environment along with agricultural and industrial production activities is very important. The issue of environmental pollution and the creation of a sustainable environment is the main concern of all humans on earth. Fortunately, with the use of biotechnology and the available capabilities in nature, the Environmental damage rate can be minimized.
