Troposphere And The LA County Air Pollution Control District

775 Words4 Pages

On July 26, 1943, a heavy blanket of smog attacked Los Angeles. The people of LA were scared. It was the midst of WWII and many presumed it was an outside attack, but it was just the opposite. It wasn’t until the early 50’s that scientists decided to tell Californians that the car they loved was really a death chamber, because the fumes from tailpipes were the source of their smog problem (McNally, J). The exhaust from their cars was releasing pollutants into the Troposphere. The Troposphere is the lower atmosphere that is the source of all weather, water vapor, and clouds. It is common for pollutants to be removed from the Troposphere within a matter of days, but if serious pollution continues, it could reach the stratosphere which is a much …show more content…

Studies have also proved Smog to be the cause of headaches, nausea, and eye/throat irritation. After extensive research, it was apparent that LA had to do something about this problem. Four years after the initial smog attack, Los Angeles implemented the LA County Air Pollution Control District. This was a step in the right direction but Los Angeles’ population was growing, and with more cars, came more pollution. According to the LA Almanac in just Los Angeles alone, there were 5,859,407 motor vehicles on the road in 2008 (LA, Almanac). To put this number in perspective, the amount of cars on the road in just the city of Los Angeles is greater than the entire population of Wisconsin. Although the growing infrastructure is impressive, this means intense pollution is still filling the city. As the years went on, California’s rate of emissions has been lowering, but with such a huge mass of people, the numbers are still not safe. As of the late 2010’s, California has been implementing some new technology to help save its beautiful beaches and sunshine. Some of these new technologies include limiting pollutants from the vehicles that inhibit the city with catalytic converters. Cars now release 90% less pollutants than the cars in 1970. This number is extremely impressive because it takes into consideration the increased amount of cars form the 70’s as well as the increased mileage each car is being driven now that the infrastructure of America has developed so

Seasons typically divide a year into four parts (spring, summer, autumn, and winter). Weather is constantly changing throughout the year based on the current location of the sun in accordance to earth. The world relies on seasons to thrive, for instance, autumn is when nature shows its true beauty, bringing rain to quench the parched lips of summer. Although the changing of seasons may not be apparent in certain parts of the world, they are the key to human life. In “Something Uneasy in the Los Angeles Air,” Adrian Glick Kudler informs the public about Santa Ana winds in addition to introducing writers to back up her ideas.

The reason California did this was to strictly regulate greenhouse gases such as carbon dioxide. The EPA struck this bill down, yet California is still trying to enforce the carbon dioxide to lessen air pollutants. In California each vehicle after a certain year must pass a smog emission test. If the vehicle does not pass the test it must undergo a certain amount in dollars of repairs to correct the problem. In many cases the vehicle did not pass because of a faulty catalytic converter, or an ill tuned up vehicle.

(U.S. Department of Transportation 2017) The American government was concerned of the overwhelming gas dependency of the nation and found ways to regulate the vehicle industry. In the past 40 years, American manufacturing companies have evolved their vehicle designs to make their products more efficient in MPG. This incentive, produced by energy policy, has allowed consumers to benefit from better products. The technology-based approach has forced automobile companies to comply with more regulation and invest more in the design of the efficiency of their products.

Power plants releases smoke and ash during processing of burning of coal contributed significantly to the problem of air pollution in the late 19th and early 20th centuries. In 1940 air pollution in the United States and the complaints of the public pressured the government to do something about the problem, the government regulators had to act. The smog that formed around Los Angeles and other big cities around began to report air quality degradation. California was the first state to pass air pollution regulations. In 1947 just shortly after California acted the government convened the first national air pollution symposium consisting of the environmental experts and the representatives of the government.

A major issue today is the emissions of greenhouse gasses, which harm the ozone layer causing climate change. Internal combustion vehicles are one of the contributors to the greenhouse gas effect and can be reduced by diminishing the use of internal combustion vehicles and introduce electric vehicles. In the article “The car and fuel of the future” Joseph Romm a former Acting Assistant Secretary at the US Department of Energy's Office of Energy Efficiency and Renewable Energy, states that “the car of the near future is the hybrid gasoline-electric vehicle because it can reduce gasoline consumption and greenhouse gas emissions 30 to 50% with no change in vehicle class and hence no loss of jobs or compromise on safety or performance. It will likely become the

First of all, let’s talk about the environment. I’m sure you all know about greenhouse gases and global warming, so I won’t talk much about that, but you may not know that road vehicles produce 10% of all man-made greenhouse gas emissions. This does include vehicles other than cars like trucks, but Tesla just came out with an electric truck which is faster and can carry more weight than any petrol/diesel truck. Greenhouses gases carbon-dioxide and methane have hit their highest levels in the past 420,000 years, and the extent of arctic sea ice has declined about 10% in the last 30 years.

This is all because of global warming, and if we start switching to electric cars, we could make a big difference and maybe, just maybe the effects of global warming will decrease.

Many laws, and restrictions have been passed over the last few decades, restricting manufactures to specific requirements for their emissions, vehicles in general, and even the gasoline that they run on, with requirements for detergents and such,. Unfortunately, it is claimed that these systems don’t have big enough impact on lowering the environmental problem, due to the amount of vehicles out there. Luckily, since electric vehicles are becoming more affordable, practical, and appealing, the amount of problems associated with the amount of claimed pollution will

Good Afternoon Everyone “The best solution to pollution is dilution”. According to the United States Environmental Protection Agency’s’ report of 2010 Transportation contributes 13% to the global greenhouse gas emissions. So, have you ever thought of diluting the emissions by switching to Hybrid Vehicles? You may be thinking that Hybrid Vehicles are modern inventions due to technological advancements but did you know that it existed prior to the invention of the conventional gasoline vehicles.

I feel concerned that anthropogenic activities have damaged the atmosphere which has led to severe detrimental effects over time. Studying Chemistry enabled me to learn the science behind global warming and the consequences for it. This made me think, what current technology could be further utilised to reduce greenhouse gas emission to the atmosphere? Due to this, I want to talk about electric vehicles as I feel that electric cars are the future of humankind. I will persuade you to leave behind the poisonous, toxic, filthy fumes of your present vehicle and switch to an electric car.

There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
