Acid rain releases aluminium from the soils into the water, an element which is highly toxic to many species of aquatic organisms. Sulfur dioxide itself is a pungent gas which causes breathing difficulties at low concentrations. Nitrogen dioxide can cause respiratory difficulties and damages organ tissue. Under the influence of sunlight, it produces ozone, photochemical smog. Carbon dioxide is an significant contributor to the enhanced greenhouse effect.
Tule fog is a very thick fog that collects in parts of California during the rainy season of the late fall and winter. It has also been known to gather from Bakersfield to chico and occasionally in San Francisco. Tule fog is a type of radiation fog that is created due to the rising of warm air. http://www.wisegeek.com/what-is-tule-fog.htm The cold mountain air descends into the San Joaquin Valley and usually forms Tule fog on the first or second clear night after it has rained, skies are cleared and winds are light. This happens when high-pressure returns, creating an inversion with colder air near the earth's surface than aloft.
Negative affects relating to urbanisation is becoming increasingly concerning especially as there is an increased number of people who are moving out of the rural area into the urban/suburban areas. One of the causes of the heat island effect is the lack of vegetation in urban areas, the soil and vegetation would normally take part in photosynthesis and use the absorbed the sunlight to do the process of evaportranspiration. Another cause of the heat island is that the materials used on buildings such as concrete, bricks and tarmac all act like bare rock surfaces and so they absorb large quantities of heat throughout the day especially due to their dark colour. This heat is then stored during the day and slowly released at night. Many urban surfaces such as buildings with large windows have a high reflective capacity; many multi-storey buildings tend to concentrate the heating effect in the surrounding streets by reflecting the heat energy downwards.
1b)Coal is a fossil fuel, which means when it is burnt it releases unwanted pollutants which have a negative and harmful impact on our environment. These pollutants are: Carbon Dioxide- This gas is considered to be the most harmful pollutant as it contributes to global warming. Coal is attributed to approximately 20% of the total pollution globally per year of all the fossil fuels. Sulfur emissions- when sulfur mixes with oxygen a harmful substance is formed. SO2, sulfur dioxide effects our trees and water systems and is the prominent cause of acid rain.
Also air conditioners exchange heat with atmospheric air, causing further local heating. Additionally, concrete, needed for the expansion of cities, absorb huge amounts of heat, increasing the mean surface temperatures of urban areas. Tall buildings, and often, accompanying narrow streets, hinder the circulation of air, reduce the wind speed, and thus reduce any natural cooling effects.
2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
Atmospheric Pollution Environmental Science SCI 275 University of Phoenix July 29, 2011 BY Reigard U. Brown Sr. The paper that I am writing will be about one of the problems we have in the world is Atmospheric pollution. Atmospheric pollution is the introduction of chemicals, particulate matter that cause harm or discomfort to humans and living organisms in our atmosphere. There are many different ways that air pollution can be omitted into the air we breathe like pollution that comes from house cleaning products, older model cars, energy plants, and forests fire.
HIGH LEVEL OF FORMALDEHYDE INDOOR AIR QUALITY Formaldehyde is a flammable, colorless gas that has strong smell mainly emitted from household products and building materials. Formaldehyde can be found at high levels in air which has strong smell. High levels can cause irritation of the eye, nose and throat, and can make asthma symptoms worse in children and infants. The recent research conducted by California Air Resources Board (CARB) is the first detailed analysis of environmental contaminant and exposures for day cares. The research covered 40 day care centres across the city which showed high level of formaldehyde (87%) in the centres.
“Their influence is known as the greenhouse gases, which are carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor”(“American Meteorological Society 2007”). These gases mixes with the sun ultraviolet rays, disburse into the earth atmosphere with harmful results. Carbon dioxide from the burning of fossil fuels is one way the human activities effects the environment. Carbon dioxide from the exhaust of cars in heavily polluted cities, farming machinery such as tractors, and smokestacks of refinery companies are just some of the ways carbon dioxide gases are release into the atmosphere by human contributors. The nitrous oxide gases affect the aquatic ecosystem food web chains, which leads from the smallest phytoplankton up to the largest mammal, which is man.
Brent Rosinski Professor Duane Smith Speech 101 Sec #7405 January 31, 2012 The Negative Effects of Traffic on Commuters I. Introduction: What every day activity is one of the biggest wastes of time, money, and takes years off your life? The correct answer is traffic jams. According to Readers Digest UK in November 2011, excessive traffic jams result in wasted fuel, lost productivity due to tardiness, and high levels of stress, frustration, and road rage, which can contribute to reduced health. In addition, research suggests that exposure to high levels of traffic-related air pollution by motorists appears to boost the risk for experiencing a heart attack, as reported by USA Today on September 21, 2011.
