Trophosperic Ozone :: essays research papers

The source of the tropospheric ozone The tropospheric ozone has two major sources. One is intrusion from the stratosphere. Most of ozone in the atmosphere is in the stratosphere and created from solar UV radiation. The stratospheric ozone sometimes flows into the troposphere by the upper layer trough and cut-off low activities. Some part of ozone may subside in the troposphere directly by the Hadley circulation or the Brewer Dobson circulation. Another source is production from photochemical reactions. Ozone is produced from relatively longer-wavelength solar radiation under NOx and non-methane hydrocarbons rich environments. These photochemical reactions possibly bring about photochemical smog in urban area. http://www.asahi-net.or.jp/~wt2y-ttm/what.htm The characteristics of the tropospheric ozone About 8 % of the total column ozone is in the troposphere. The tropospheric ozone also plays an important role in the atmosphere. 1) Ozone is a green house gas and possibly contributes to the global warming. 2) Ozone is harmful for human being and crops in the troposphere. 3) Ozone oxidizes many chemical substances in the troposphere, and controls tropospheric chemistry. The trend of the troposheric ozone Some global monitoring stations show the increase of ozone in the troposphere. It may be a big problem, because if tropospheric ozone increases, it might damage to human beings and many crops, and fairly contribute to the global warming and change the tropospheric chemistry. If the tropospheric chemistry changes, the nature of pollution and acid rain might change. But not all monitoring stations show the increasing trend. We have to monitor the tropospheric ozone at many suitable observation points. This also has the mean to study influence of human activities on Nature. Causes of ground-level ozone Other culprits-besides car and truck exhaust-are gas lawn mowers, over-filling and topping-off a gas tank, which allows vapors to escape, and leaking fuel, which react with sunlight and heat to produce ozone. Alternatives that reduce air pollution and ground-level ozone include using native plants for landscaping rather than a lawn, using an electric or push mower, limiting planting areas for lawns, carpooling and public transportation. Effects on people with preemptive respitoary problems Ground-level ozone can cause flare-ups of asthma, chronic bronchitis, other lung diseases and cardiorespiratory illnesses. Symptoms may take days to appear following exposure. Ground-level ozone can decrease lung function and cause chest tightness and coughing. In addition, ozone and microscopic particulates, small enough to be inhaled into the lungs and "sticky" enough to attract pollens and other allergens, can contribute to asthma and allergy attacks, and make other lung diseases more severe.

“Farm Girl” by Jessica Hemauer Essay

â€Å"Farm Girl†, is an essay by Jessica Hemauer, who is trying to fit in with other kids at her school. She lives on a farm where she has her responsibilities before school and after school, and she is not able to participate in school functions or other activities that the other kids get to do. Her dream is to join basketball and other clubs because she feels that is the only way she will fit in with everyone else at school. Jessica wakes up at 5 with her sisters, Angie and Melissa and her brother, Nick so they can help their father with the morning chores on the farm. It does not matter what else is going on with the family they have to get up every morning and help with the chores. After they get up they have a routine of getting dressed and head down to the basement, where they keep their outside clothes, so they do not stick up the house. They put on their barn clothes and head out to the barn to help their father. Jessica has her chores and so does her brother and siste rs. Jessica has to help her sisters with sanitizing the milk machines, prepare the milk equipment and set up the station with towels and charts the cows that need medication. The other thing Jessica does, which is her favorite thing to do, is feed the newborn calves. She loves doing this job because she finally gets to take care of something that is not taking care of her. After she was done with that, all the kids help and clean out the pens and lay fresh straw down. Jessica does not like this job too much because it is the dirtiest job they have to do. She gets done with her morning chores about 7:30 and head back to the house to get ready for school. Once back in the basement they hang their farm clothes over a folding chair near the washing machine. As they head up the stairs, to get showers and get ready for school they can smell smoked bacon and cheese omelets being cooked. As she is running out the door yelling at the bus,† Wait!† she grabbed herself a glass of freshly squeezed orange juice. In school, the other kids are just rolling out of bed, and I have been up for hours. While other classmates are thinking of what shows to watch on TV, Jessica is thinking about all the chores she has to do when she gets home from school. Jessica has no social life except in school. Jessica would love to join a team or club after school, but with her chores she is not be able to go to practice like the other teammates. Being raised on a farm makes her feel difference from the other kids in her grade. Jessica feels left out and depressed because she cannot join in on conversations about what the kids are doing in school. â€Å"Hey, Carrie, how was basketball practice last night?† Susan asked. â€Å"It was terrible! Coach was in such a bad mood!† Carrie replied. â€Å"He made us run sprints for every shot we missed. Kelly was missing all her shots last night. I am so sore today.†(Roen/Glau/Maid 2011 pg 85) Jessica would sit in silence, eating French fries, listening to her friends talking and laughing and waiting for the lunch period to end. In eighth grade, she wanted to play basketball, she pleaded with her parents and they finally gave in and said she could play. One of the conditions was that after practice, she had to come home and do all her chores and homework, and she agreed. She became a starting point guard. She finally starts to feel like part of a group. She never tells friends or teachers that she goes home every night and does chores on the farm because she did not want them to know she was different. In High School Jessica, is more involved with school. The farm has grown to two hundred cows. In ninth grade, she continued to play basketball, and she kept up with her chores before and after school. After her ninth grade year, her father called a family meeting to inform them that he would like the farm to keep growing and that he needs more help than the family can provide. He told them that they no longer had to work on the farm anymore unless they wanted to. He wants his children more involved in school and to go off to college. So after that meeting, she joined homecoming club, auditions for musicals and plays and serves as president of student council and the class president. Since now, she is not working on the farm she goes and gets a waitressing job. Friends came up to her and asked her all the time how she manages her time so well. When at work she is always on time, never sick and does what she is told to do. One night she sat down and started thinking about her life. She thought that joining clubs and doing activities would make her fit it, but it had not, she still felt left out. From an early age, she was taught how to manage her time wisely with school and chores. She then learned how to manage it with basketball involved. Working on the farm gave her a high tolerance for work. Her boss is always asking her for more hard working people like her. She simply tells him. †Try hiring some farm girls.†(Roan/Glau/Maid 2011 Pg 86) Jessica learned at a very young age that working hard was not a bad thing. Yes she wanted to do more in school besides get an education. Her father also noticed that his children were suffering in the end with the expansion he was planning on doing. She was glad to have had the experience that her father gave her so when she got a job she knew how to work hard.

Subtle Changes in Language Create Media Bias Essay

In the past few years, the news media has become more competitive, more extensive, and more globalized than ever before. Reporting occurs in near real time from almost any location to the consumer’s television or computer screen. With so many news agencies now vying for precious minutes of a consumer’s time, it is common for a story to undergo slight alterations that make it more emotional or sensational. Several consequent transformations of the same story can lead to extreme misreporting on the actual content, and oftentimes it is difficult to ascertain what the original story was without looking at multiple versions from different sources. The purpose of this paper is to trace the development of a news story across a 24-hour period,†¦show more content†¦The first piece of news is from NPR’s Morning Edition. The writer intended it to be a short snippet of the need-to-know points of the bailout. The main points presented are that the announcement of a bailout had a much greater effect on the Greek economy than the unveiling of a reform package earlier in the week and that Germany is planning to offer unspecified aid to the country. The reporter also mentions that many oppose the bailout because they feel it will set a precedent for â€Å"eurozone† nations who encounter a similar problem in the future. There are no sources cited for the information in the piece, but the quotation is from someone who appears to be respectable. This piece makes the problem seem much simpler than the other articles do. While no citations are present, NPR is such a respected institution on its own that none seem necessary. The reporter’s work is transparent, and all of the key questions are answered, to some degree of clarity. Context is well established, and the report represents both the pros and cons of the bailout. Overall, this is a reliable piece of news. The second news piece is an article from the Guardian, a Great Bri tain-based newspaper. Its main point is that a bailout plan has been reached, and, in contrast to the NPR piece, uses a quote from the EU’s president to make that point. It offers other information as well, most of it quoted from such figures as Germany’s chancellor and France’s president, including that theShow MoreRelatedThe Impact Of Media On Society s Society1375 Words   |  6 Pagesblamed on how the media portrays race.
