Since the industry revolution, environmental pollution has gradually become a global problem. It has looks set to hog the limelight in the century. Almost all the countries suffer from such problems and are struggling to keep their heads over the water. Air pollution is something in the air that causes harm to humans or the environment. There are many different forms of air pollutants and these are broken down further into primary and secondary pollutants. A primary pollutant is something that stems directly from a source such as volcanic ash or vehicle emissions. A secondary pollutant forms when two pollutants react in the atmosphere such as acid rain.…
Air pollution is the introduction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment. (Godish)…
Although researches had been made and people start to know about acid rain, the fact that we live in a world that uses fossil fuel in almost all the electricity that powers modern life causes the acid rain to be emitted more and more into the atmosphere. Nowadays, the air pollution had reached to a point where the idea of reducing acid rain is not a subject of individual and scientists anymore; instead it is also our responsibility as people that live in the same world to know more about this matter and learn ways to help prevent it from getting worse.…
Since the beginnings of the Industrial Age in the mid 19th century, the earth has experienced a very rapid increase in the amount of pollutants in the air and the water, due to emissions from automobiles, factories, chemical plants and other manufacturing methods which use fossil fuels, such as coal and petroleum, to create power. But within the last thirty years or so, the amount of pollution in our air and water has reached what some consider as a tipping point, meaning that pollution is slowly yet surely poisoning not only our air and water but also living environments all over the planet. Many proposals have been put forward concerning ways to decrease pollution and to help slow down global warming, yet the causes and effects of air and…
2. There were many combinations that showed if it was positive or negative charges. The positive combinations were the glass and fur (3.108 nC), clear plastic and fur (45.07 nC), glass and silk (1.979 nC), clear plastic and silk (19.60 nC), glass and green cloth (2.914 nC), clear plastic and green cloth (31.09 nC) materials. The negative combinations were the yellow plastic and fur (-81.57 nC), yellow plastic and silk (-75.49 nC), and yellow plastic and green cloth (90.30 nC) materials. The results are positive when the electrons flow from the glass and clear plastic because these materials have more electrons than the other materials, thus the electrons would flow from high concentration to low concentration. When the combinations are negative, that means that the electrons would flow into…
Because of all listed reasons the protection of environment is one of the most important and most demanding challenges placed in front of European Union to deal with. There have been many criticisms made that European Union is placing trade and economic development before care for environment. That is also one of the reasons why European Union decided to defend ratification of Kyoto protocol. This protocol places obligatory boundary values for emissions of greenhouse gases in industrialized states and is appointing new implementing mechanisms, founded on market laws, such as trading with emission coupons, common implementation and “mechanism of clean development”. Consequences of polluted environment are visibly reflected on health of all citizens of European Union. Especially in urban environment where noise, stress, air and water pollution are cause of many health conditions and allergies. Also on field of saving energy and dealing with waist a lot has been done already, however it is still necessary to look in to other numerous possibility 's for reducing to health harmful effects of wast materials.…
As we know, air pollution is big challenge for the world. Air pollution is not national problem. An under developed country like India control of air pollution is very necessary. Air pollution due to industrial west, automobile & by nature. But among that air pollution due to automobile 70% of total air pollution. So now a day control of automobile pollution & its bad effect is very necessary. We have several ways for controlling automobile pollution, but most effective way is by using catalytic converter in the automobile.…

Electrostatics is a part of physics is that the study and analysis of electricity, its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C., Thales learned that when he rubbed amber with fur, it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity, which comes from the Greek word, elektron, which means amber. Thales, who is now known as one of the Seven Wise Men, is believed to be the first person to ever experiment with electrostatics. After the death of Thales, no further experiments were conducted dealing with electrostatics until the 17th century when a man by the name of William Gilbert continued Thales’s research. He studied magnetism and static electricity. Gilbert repeated the experiment by Thales with rubbing and charging objects using friction. He later invented the word “electric” to label the forces at work for whenever an object repelled or attracted the other one. He discovered that when objects rubbed, the act removed a fluid (humour) from one of the objects and it also left an atmosphere (effluvium) around the object.…
Everyday actions cause pollutants; one major contributor to air pollution that humans produce is carbon monoxide. We do this simply by driving our automobiles. This toxic pollutant is considered a primary air pollutant because it enters our air directly from the source; our motor vehicles. Human made pollution is something that we can change by using less fuel, coal and oil in our cars, home and factories. Standards have been set by government agencies to help regulate the levels of pollutants in the air. In many cases it is too late. The air pollution control act of 1955, which established federal grants for research and the Clean Air Act (CAA) that further extended the federal government powers for direct intervention to reduce pollution, were established because of increasing detriments to human’s health and the environment. (Christoforou, 2004) The health hazards that are a result of air pollution have become more common to our elderly and young children. Lung disease, asthma, chest pain or even death, are the results of our careless activities. In the 1930s in Belgium, SO2,(sulfur dioxide), and particulate matter combined with high relative humidity and caused 65 deaths in less than 5 days (Christoforou, 2004).…
The world motor vehicle population exceeds 1 billion units at the moment. These vehicles are used for transportation of people and products across various places around the world. As a result, they emit many pollutants. This is attributable to the action of their engines burning fuel to release energy, which is an inefficient process. Firstly, they release particulate matter consisting of both organic and inorganic substances into the atmosphere, through exhaust emissions. Secondly, they release Volatile Organic Compounds (VOCs), which have carcinogenic effects. Pollution from vehicles is a universally acknowledged problem. However, it varies depending on the nation and its population. For example, pollution from cars contributes to between 50 to 90 percent of the total in urban areas. This may not be the same for rural areas. However, motor vehicles still present a disadvantage to the environment and human life. It is, therefore, prudent to develop countermeasures to automobile-exhaust pollution.…
The purpose of this research is to introduce two different recent scientific advances that can solve the issues of carbon dioxide .Nowadays ,carbon dioxide problem can seriously affected our environment and our daily lives . There are several harmful aspects of carbon dioxide : high concentration causes narcosis , and it increase the cerebral blood flow and intracranial pressure .and the most serious things is it can reduces ozone sphere concentration. As carbon dioxide continues to burgeon in the atmosphere causing the Earth's climate to warm ,scientist are trying to find ways to remove the excess gas from the atmosphere and store it where it can cause no trouble .There two current scientific advances both can help human deal with issues of carbon dioxide.…
The history of acid rain caused by human activities began with the industrial Revolution in about 1750. This is when steam power began to be used to drive machinery. This was when large amounts of fossil fuels (coal, petroleum and natural gas) began to be burnt in order to produce energy. The problem of acid rain became gradually worse until 20th century, scientists began to observe widespread environmental damage. Since the problem of acid rain is discovered, changes have been made to prevent further damage to the environment and to undo the existing damage. For example, vehicles exhaust fumes which contain large amounts of nitrogen oxides and some sulphur dioxide. Much has been done to reduce these since 1983 in United States and 1993 in Europe, new cars have been…
The earth’s atmosphere is a constantly moving body of gases that encircle our planet. This body of gases known as air is a mixture, not a chemical combination, of a number of gases; that is, each gas retains its own characteristic properties. It consists of about 78 percent nitrogen; 21 percent oxygen, and carries along with it water vapor, clouds, dust, smoke, soot, and a variety of chemical compounds. The remaining one percent contains all the other gases including carbon monoxide, carbon dioxide, ozone, methane, and ammonia that contribute to harmful pollutants that are released into the air. Millions of tons of harmful gases are released into the air each year. According to The World Health Organization, 2.4 million people die each year from causes directly attributable to air pollution, with 1.5 million of these deaths attributable to in-door air pollution (World Health Organization, www.who.int). For the past several decades’ air pollution has become more of a health risk factor. What is air pollution? Air pollution is air that enters our atmosphere that contains undesirable substances such as gases, dust, chemicals, particulate matter, biological materials, fumes or odor in harmful amounts. That is, amounts which could be harmful to the health or comfort or humans and animals or which could cause damage to plants and materials. The use and release of certain chemicals can be of serious concern if they have significant impacts on human health or the environment. The substances that cause air pollution are called pollutants. An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Pollutants can be classified as primary or secondary. Primary pollutants are directly…
Air pollution, water pollution, global warming, and ozone depletion are some of the issues we confront every day that mirror the outcomes of our activities. Satti Swami Reddy and Kola Siva Tharun, (2013) said the cars we drive emit exhaust gas, whose harmful components affects the environment which causes acid rain and global warming. Carbon dioxide is one of the main greenhouse gas which is emitted to the thin air through human activities through the burning of fossil fills such as coal, natural gas and oil for energy and transportation. Due to high environmental concerns, various countries have been attempting to try resolving these problems and one the outcome is the invention of hybrid cars, which can help contribute to save the environment by giving off less emission. Yost (2006) said the innovation of hybrid cars have helped to decrease gas emission especially carbon dioxide considerably to…
