Photochemical Smog

The process begins when the sun starts to heats up the surface which creates warm air. The warm, less heavy air rises and converges with the cold less heavy air above. This process is known as wind shears. Wind shears are when two

Cool air has higher air pressure so it flows underneath the warm, less dense air.

1. What is the difference between the type of smog experienced by cities in the eastern United States and that found in Southern California? early people burned wood for heat and cooking fires in enclosed spaces such as caves and small tents or houses. And Photochemical smog is the abundance of cars and sunshine that provided the perfect setting for a chemical reaction between some of the molecules in auto exhaust or oil refinery emissions.

develop into dust storms. Nights are very cold, but the days are comfortable. The surface

Yes, I agree with your post. I just would like to comment regarding the air pollution. The pollution in the air causes quite a few problems in the nineteenth century such as: the trees started to dye, the smoke irritated the nose and they was prone to other diseases. “The poor immigrants and blacks who lived and worked in crowed inner cities were especially prone to diphtheria and pneumonia” (Merchant, 120). The air pollution was mainly in the towns where there was coal burning

When the sunlight hits particles in the ground, the particles in the ground heat up.

The Great Smog of '52 occurred in London from December 5th to December 9th in 1952. This was when a thick fog covered London with a mixture of black smoke emitted from homes and factories, leading to a deadly smog (1). A severe cold weather hit London in December 1952. The people in London burned more coal to heat their homes because this is what they usually did when the weather became cold. On December 5th, 1952, a layer of dense fog engulfed the city and stayed for about five days. Since the air pollutants from the burning of coal were prevented from escaping into the atmosphere by an inversion, this caused the fog to form. Most of the people living in London were not surprised by this fog since the city was known for its"pea-soup fogs.

Paragraph: Let’s take a look at human activities cause the air pollution. First is the emissions from industries. When we look at the manufacturing plants, you will notice that there are long tubes erected high into the air, with lots of smoke coming out of it. Manufacturing industries and power plants emit high levels of carbon monoxide, organic compounds, and chemicals into the air from that. This happens almost everywhere people live.

Have you ever wondered what light pollution is? Light pollution is the effect of artificial lights on the night sky. The problems of light pollution in the United States includes the hampers of our view of some of life’s most spectacular sights, the harming of wildlife and it prevents us from seeing the night sky.

In the late 18th century coal became a huge factor for the Industrial Revolution which caused smog to be a serious health hazard. "Ozone reacts chemically (“oxidizes”) with internal body tissues that it comes in contact with, such as those in the lung” (Water and Air). One of the top causes today of air pollution is motor vehicles. The heating of our atmosphere by the increase of greenhouse gases is known by global warming. "In 1952, pollutants from factories and home fireplaces mixed with air condensation killed at least 4,000 people in London over the course of several days" (Water and Air). Still today, many do not see this as a major health

I am Grayson Hunt, and I live in Springfield, Missouri. I am qualified to write and publish this editorial because I am aware of some of the Great Lakes great atrocities causing harm and even death within the lakes. I am appalled with the information that has been revealed and made known to me, and I want to express that information to everybody concerned. It is important that everyone is aware of what happens within our Great Lakes and country overall!

While the mechanisms are poorly understood many scientists are suggesting the interaction of sunlight with air pollutants creates a cascade of reactive species which increase the amount of air pollutants as well as their potency3. For example, sulfur dioxide and particulate matter emissions from a coal-fired power plant may react in air to produce acid sulfates and aerosols which are highly penetrable to the airways and travel long distances before settling.

The military creates varies health problems for people and contaminates the environment. The military produces more pollution than any other institute, yet there is less regulation for military pollution. Military operations affect the land, water, air, ocean, and people health who live near the military bases and training areas. The affects are caused by the usage of fuels, oils, solvents, and heavy metals. Atomic test that the military did in the Pacific contaminated soil and water for future generations. The radiation caused women in Micronesian to give birth children who had serve disabilities. In addition, the radioactive exposure caused Pacific Island men and women to contracted several types of cancer. This section was very informing

Air, is one of the most substantial source to mankind and our planet. While it exists, so does everything else along. However, in today’s epidemic, there has been certain factors that have increased in understanding whether the air we breathe today is healthy or not? Is it doing more harm than we thought? In other words, the health risks against air pollution have risen in the past few decades; all from what you may ask? Well, it could be for various factors and evaluations; either environmental or materialistic. Pollution is a major public health crisis in the world. (Friis, 2012). This is one of the conflicts that contribute to various aspects of an individual’s life, whether they may realize it or not. In this paper will include the sources that cause pollution with the effects it cause as well as policies on the regulation of air pollution.

Since the Industrial Revolution, there has been an increased presence of pollutants and carcinogens in the environment, specif-ically in urban areas.1 The presence of airborne pollutants can lead to an increase in allergic reactions and asthma rates. A common airborne pollutant is carbon monoxide (CO), which is commonly found in diesel exhaust. It is an odorless gas produced from me-thane and non-methane hydrocarbon oxidation.2 The toxic gas eliminates and takes the place of oxygen in the form of carboxy-hemoglobin when it binds to hemoglobin in red blood cells. It also affects the binding sites of heme groups, which complicates the transfer of oxygen to tissues.3 The majority of deaths from carbon monoxide poisoning is brought on from car exhaust.4 Between the years 1979 and 1988, 57% of deaths from carbon monoxide poi-soning were brought from car exhaust. There tend to be higher rates of carbon monoxide poisoning from car exhaust in northern regions, where temperatures are relatively low (Figure 1). 5
