Conversely, Chemical plants can contaminate the pure water or create harmful diseases to humans and the Earth. The West Virginia chemical spill demonstrates the dangers chemical plants pose to our environment, and it is important to understand the devastating
Typical Viruses are illnesses like smallpox, measles, mumps and tuberculosis etc which can be contracted by touch or being within an environment that has the virus in the air. Fungus or Fungi can cause such Infections like Athletes foot, Chlamydia and Thrush. Parasites because of the way they transfer from host to host mainly by contact and can cause infections such as Malaria, Ringworm, Fleas, nits etc. (3) A description of the terms ‘Infection’ and ‘Colonisation’ are that an infection can lead to a colonisation if un monitored or un treated. An infection would be
Some of the world’s most serious and deadly diseases are viral. In order to cause disease bacteria must enter the body. Routes for bacteria include; cuts, contact with infected faeces, contaminated food or water, close contact with an infected person, breathing in droplets from an infected persons cough or sneeze or indirectly by touching a contaminated surface. Viruses can be spread from one person to another through coughs and sneezes, vomit, exposure to infected bodily fluids, sexual intercourse and sharing infected needles. Fungi infections, there are several types of fungal infections.
When we refine or even dig up oil sands we produce harmful chemicals. Since Alberta oil sands are located near major rivers some of those chemicals end up in the rivers. The most famous case is with the Athabasca River, where the water is contaminated by many harmful chemicals. The Athabasca water ecosystem is slowly being poisoned and so are the people that use the water for their water supply. The oil sands maybe a large part of our social and economic structure, but they are slowly ruining our environment.
VOCs were broken down into specific contaminants which include chlorobenzene, 1, 2, 4-trichlorobenzene, and trichloroethene (EPA, 2012). Chlorobenzene also known as mono-chlorobenzene is a toxic chemical that is frequently used in manufacturing and producing pesticides such as DDT (OEHHA, 2000). Mono-chlorobenzene can also be used in to produce other manmade chemicals such as nitrochlorobenzenes and diphenyl oxide. All chemicals listed have been used primarily to create herbicides, rubber chemicals, and one of Ciba-Geigy Corporations largest product, dye. The chemical is a colorless liquid which makes it nearly impossible to detect in water and has the ability to harm the population by inhaling the polluted air (OEHHA, 2000).
Phenylalanine also disrupts amino acid metabolism, hormonal equilibrium, and nerve functions. Aspartic acid is believed to function as an excitatory neurotransmitter in the central nervous system (CNS). Methanol gets converted to formate, it is either excreted or it gets accumulated in the body to form formaldehyde, diketopiperazine (a carcinogen), and other potent toxic products.

corinthians college inc. | Non-Native Species | Environmental Science 1001M | | Clara Negrete | 6/11/2011 | This document is based on discussing the depths of introducing invasive species in the state of California. | There are many different types of invasive species that are not native to California. Some of them are persea mites and avocado thrips that attack avocados. These are native to Mexico where the where avocados come from. Here we have some species that are native to the United States but still can be invasive if they are moved to another part of the same country.
Approximately _____15,00_____ acres of fresh tomatoes and ____110,000______ acres of processing tomatoes are grown annually in the southern San Joaquin Valley. True or (False) (italicize one): California is NOT the major supplier of carrots for the US. http://pubs.usgs.gov/circ/circ1182/pdf/06SanJoaquinValley.pdf Mining ground water for agriculture has enabled the San Joaquin Valley of California to become one of the world’s most productive agricultural regions, while simultaneously contributing to what? ____to one of the single largest alterations of the land surface attributed to humankind.___ California ranks as the largest agricultural producing state in the nation, producing what percent of the total U.S. agricultural value? ____11_____% The Central Valley of California produces about what percent of the nation’s table food on only 1 percentof the country’s farmland?
I have learned that the use of toxic chemicals during the fracking process and the occurring release of toxic chemicals and radioactive materials during well processing is bad for the environment. Such as, Naphthalene, Xylene, Toluene, Methylbenzene, and Formaldehyde, are all known or suspected to be human carcinogens (Schmidt). Also Hydraulic fracking hurts the environment by the contaminating the water wells, and springs, in which many humans and animals drink from. Another environment impact of hydraulic fracturing is air pollutions. Finally the way fracking impacted animal and human health.
Each of these compounds is known to be poisonous, cancerous, or cause birth defects. The EPA fears that the drinking water will compromised due to runoff of the surface water discharge. Additionally, contamination of underground sources of drinking water and inadequate treatment of the waste water are possible. The threat of contaminated water supplies can cause a fearful population, largely due to the propaganda spread by anti-fracking initiatives. Although there are potential economical disadvantages to fracking, there are also enormous positives.
