The Effects of Ozone Pollution
The term "ozone" has appeared in numerous magazine and newspaper articles and has been a subject of discussion on both radio and television. Despite all the publicity surrounding this term, however, many people are still confused by it. The confusion arises from the fact that ozone is both beneficial and harmful. We know that the ozone layer in the upper atmosphere acts as a filter for the sun's ultraviolet rays, reducing the amount of radiation that reaches the earth's surface. At ground level, though, high concentrations of ozone can be harmful.
The Ozone Layer
Ozone gas forms a layer all around the earth high in the stratosphere. It serves as a vital and effective protective barrier from the sun's ultraviolet rays. In recent years, scientists have sounded alarms internationally about the depletion of the ozone layer, citing chemical pollution as the major cause.
A specific class of chemical compounds called chlorofluorocarbons (CFCs) are most often identified as ozone destroyers. CFCs were once widely used in everything from air conditioner coolants to the propellant in aerosol cans but have now been banned in most developed nations, including the U.S.
Many scientists believe much more needs to be done to protect the ozone layer, and international efforts are ongoing.
Ozone Pollution
Ozone pollution is really an increase in the concentration of ozone in the air at ground level. Because sunlight has a critical role in its formation, ozone pollution is principally a daytime problem in the summer months. Ground-level ozone is produced when sunlight combines with hydrocarbons and nitrogen oxide, two compounds produced by cars, trucks, factories, and power-generating plants, and found wherever gasoline, diesel fuel, kerosene, oil, or natural gas are combusted. Urban areas with heavy traffic, and large industrialized communities, are the primary areas with ozone problems.
When temperatures are high and there is little wind, ground-level ozone can reach levels that are dangerous to the health. Weathermen can predict when an area will be subject to high ozone levels and issue alerts according to the Environmental Protection Agency's Air Quality Index (AQI). When the AQI is in the moderate, or yellow, category, for ozone, people who are unusually sensitive may experience problems. A higher level of alert (orange, red, purple, or maroon) carries added risk.
Who Is At Risk?
Some people are at especially high risk for health problems associated with ozone. These include children, who normally spend a lot of
Dance was being developed in the Courts of Italy and France because the courtiers would pay dance masters to create dances for their celebrations and festivals.
”(Geduld) Although most of these deaths are from long term exposure to the pollutants there was still “2,682 deaths caused from short term exposure. ”(Geduld).“5.5 percent of cardiopulmonary (heart and lung disease related) deaths can be attributed to ground-level ozone exposure, which has increased over the past decade.” (David Suzuki Foundation) There were also “92’000 emergency-room visits and 620,000 visits to a doctor’s office in a year” It is estimated that by “2031 90,000 people will have died from short term exposure and 710,000 from long-term exposure to air pollution.
When CFC molecules reach the stratosphere, the sun's radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the amount of UV radiation that reaches the Earth can double. Ozone depletion serves as a major health risk for human beings. The three primary health effects of ultraviolet radiation on human health are damage to the skin,eyes, and immune system.
In the 1970 's, this form of dance was started in the Bronx. Any song that people listen to today can be stripped down to a simple pattern that is repeating, this is what gives rhythm. DJ’s repeated these patterns over and over and then a beat emerged that could be danced to. This is known as a breakbeat (nowadays it is becoming another genre of music). “Break dancing” gets its name from this very concept; the breakbeat gives dancers a steady rhythm to move to. Unlike any other dance performance that is done on a street, break dancing is quite different. Break dancing is a way to express your character by performing various types of moves. This type of dance was not done solo when it originated but it has evolved as more people have gained interest in it. Typically, a first dancer would made a move by performing a segment of their dance, the next dancer would comprehend that move and reply to it in a creative manner. Just like graffiti, this type of dance was very unique to everyone to participated in it. When break dancing originated, the aim was to be quick and determined. The first ones who started participating in this form of dance were the youth and people in street gangs. It became more widespread later but the kids and people within their gangs used this form to “battle” each other. This dancing acted as a substitute for physical violence back in the 1970s. Nowadays, we know these by the name
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
Dance has been around for ages. It comes in all different forms, styles, and purposes. From the four main purposes of early dance such as, fertility, healing of the sick, warfare, and even solidifying the community. To even partaking in social dancing. It is universal and something everyone can do no matter a person’s ethnicity, religion, or gender. Instead of the mind expressing the emotions that we are feeling, many can use their bodies by dancing instead. Some dance to the rhythm of music or even just simply moving their bodies without music. If there is one thing that many cultures all over the world have in common, it is dance. Dance
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Air pollution is caused by many things such as car fumes, burning of fossil fuels,
Warmer global temperatures affect farming, wildlife, sea levels and natural landscapes. The effects of car pollution are widespread, affecting air, soil and water quality. Nitrous oxide contributes to the depletion of the ozone layer, which shields the Earth from harmful ultraviolet radiation from the sun. Sulfur dioxide and nitrogen dioxide mix with rainwater to create acid rain, which damages crops, forests and other vegetation and buildings. Oil and fuel spills from cars and trucks seep into the soil near highways, and discarded fuel and particulates from vehicle emissions contaminate lakes, rivers and wetlands. Air pollution from cars and trucks is split into primary and secondary pollution. Primary pollution is emitted directly into the atmosphere; secondary pollution results from chemical reactions between pollutants in the atmosphere. The following are the major pollutants from motor vehicles: Particulate matter (PM), Hydrocarbons (HC), Nitrogen oxides (Nix), Carbon monoxide (CO), Sulfur dioxide (SO2), Hazardous air pollutants (toxics), Greenhouse
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer?
During the 1920s the new dances The Black bottom and The Charleston were born. The Black bottom originated in New Orleans as a stamping, swaying “Negro” dance. Musical Producer George White saw the Black bottom performed in a Harlem nightclub. White bought the music and introduced it to white audiences in his “Scandals of 1926.” The dance was then popularized and modified for the ballroom. Scholars of African dance have traced the Charleston to Trinidad and West Africa. In the nineteenth century, black minstrel dancers danced the “patting Juba,” a routine of slapping the hands and the knees, thighs, and body in a rhythmic d...
Ozone depletion has adverse effects on agriculture, forestry, marine ecosystems and polar ice caps. Aquatic food webs are affected in terms of development and growth; this disrupts biological processes. Due to more ultraviolet radiation reaching the earth’s surface, polar ice caps melts and this increases the sea level, which in turn can cause major flooding in low coastal regions. There is a decline in phytoplankton, as water is transparent and due to the high amounts of UV radiation reaching 0.5 meters below surface, it intoxicates the phytoplankton. (Bais et al.,
they create many breathing and heart conditions like cancer and other threats in the body, that is why children who are exposed through air pollutants are most likely to have pneumonia and asthma.
The ozone layer is in stratosphere, region of the atmosphere 11km - 50km above the surface of the Earth. Firstly, this layer of ozone reflects most ultraviolet sunlight (UV-B) from the Sun, allowing small amounts to reach the surface of the Earth. This UV-B is damaging to all life forms on Earth. Without this layer of ozone in the stratosphere UV-B radiation would negatively affect humans, animals, plants, and sea life. Secondly, the ozone layer is being deteriorated by the accumulation of chlorofluorocarbons (CFCs) (CFC is a compound of chlorine, fluorine, and carbon. CFCs are used in propellants, foaming agents, aerosol sprays, solvents, and coolants in freezers and refrigerators), halons,...
What is pollution? Pollution is a detrimental enemy to all species that walk on earth. It is a product of mankind carbon foot print on the environment. It consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. Pollution occurs when pollutants contaminate the natural surrounding; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements of pollution which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance in the environment. With innovation and development in our lives pollution has reached its peaks; giving rise to global warming and human illness. When raw materials, water, energy and other resources
