Diesel Emissions and Cancer 2 Diesel engine emissions from shipping freighters is a large source of air pollution all over the world. The Great Lakes region of the United States has very high concentrations of air pollution from these toxic emissions. The air quality in this region is considered poor. Several studies have been done linking increased rates of lung cancer to these emissions. These large vessels (shipping freighters) rank second only to power plants as to the health risk…

INTRODUCTION TO ENVIRONMENTAL POLLUTION STUDIES Pollution is the process of making the environment dirty, unsafe, or unsuitable to use. Worldwide pollution affects more than 200 million people. The two countries responsible for creating almost half of the planet’s carbon dioxide emissions is China and the United States (“Gallucci and Horn”). However, Americans are 5% of the world’s population and use 25% of the world’s resources. American’s burn up nearly 25% of coal, 26% of oil, and 27% of…

The amino acid, homocysteine, is basically a cysteine with an added methylene bridge. Methionine, an essential amino acid, gives rise to homocysteine, a sulfur-containing amino acid, through the methionine cycle. Methionine is converted to S-adenosyl methionine (SAM) when an adenosine group from ATP is added on to activate methionine’s methyl group. SAM is a methyl donor that is a substrate used in many reactions. When it donates the methyl group, SAM is converted to S-adenosyl homocysteine…

the distance, time, etc, the side effects differed significantly. As the Center for Disease Control and Prevention writes, “Exposure to sulfur mustard may increase a person's risk for lung and respiratory cancers, extensive eye exposure can cause permanent blindness, and sulfur musar can cause second- and third- degree burns an later scarring” (Facts about Sulfur Mustard, Center for Disease and Prevention). Mustard gas was more than likely fatal but when those…

3. SAFETY AND ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION 1. Safety Aspects 1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid. Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the…

The sounds of gunshots and were heard in every single war around the globe. But what fueled the guns? Gunpowder is one of the many Chinese inventions, such as silk, chopsticks, the compass, and the umbrella. It is an explosive made out of saltpeter, sulfur, and charcoal and has a blackish color. Gunpowder is the first explosive ever invented that was physical in the world. It is considered as one of China’s four greatest inventions. Gunpowder played a significant role in China and warfare…

Pollution is a term used to describe mostly particles that are harmful in the air. Many things can cause pollution weather they be human like riding the car instead of taking the bus or natural phenomena like the eruption of a volcano. Pollution can come in many forms; they can be in tiny solids ranging from a few microns to gases floating around in the atmosphere. A recent study shows that pollutants less than 10 microns in diameter are in correlation with people dying of lung and heart…

Nuclear power, we have all heard of it. Or most of us have, nuclear power is created by nuclear fission (“Nuclear Power for the 21sr Century”). The process of uranium isotopes in a controlled environment being split. As you know any action takes energy and when energy is being used or changed a by-product is made. In most cases it is thermal energy, which is heat energy. That is exactly what is happening in a nuclear power plant. When one uranium isotope is split a chain reaction is created in…

Acid rain results in many ecological effects, with the most severe of these affects being its impact on lakes, streams, and aquatic environments in general. It negatively affects marine life, because acid rain makes waters acidic, causing the absorption of Aluminum; which is a combination that threatens some aquatic animals. As the acidity of water increases, the number of fish and marine animals in general decline. Although, there are some species that are able to survive in acidic water,…

When the bacteriophages infected the bacteria, the others contained the radioactive isotopes in their structures. This was performed once for the sulfur-labeled phages and for phosphorus-labeled phages. The phage coats remained on the outside of the bacteria, while genetic material entered. Disruption of phage from the bacteria by agitation in a blender followed by centrifugation allowed for the separation…
