Environmental Impact Of The Chemical Industry In Sarnia
Sarnia's Chemical Valley and the surrounding area are home to sixty-two facilities and refineries. A widely quoted 2007 Ecojustice Canada report showed those large industrial facilities located within 25 km of Sarnia, Ontario, Canada emitted more than 131,000 tonnes of air pollution in 2005, a toxic load of more than 1,800 kilograms per resident. Particulate Matter In January 2011, the ''Sarnia Observer'' noted "Sarnia had by far the highest levels of fine particulate matter recorded at any of the province's 40 monitoring stations, with significantly sootier air than Windsor, Hamilton, Kingston, and Chatham". In September 2011, the World Health Organization reported that "While Canada ranks third in the world when it comes to air quality, Sarnia was ranked the worst city in the country, with the most particulate matter per cubic metre of air." Pamela Calvert's 2006 documentary on the Aamjiwnaang First Nation, ''The Beloved Community'', details the startling revelation t ...

Chemical Valley By A Park
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances (substances consisting of a single chemical element), chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt ( sodium chloride) and refined sugar ( sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liqu ...

Cancer Rate
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as ''Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of a cell. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esso Holding Tanks
Esso () is a trading name for ExxonMobil. Originally, the name was primarily used by its predecessor Standard Oil of New Jersey after the breakup of the original Standard Oil company in 1911. The company adopted the name "Esso" (the phonetic pronunciation of Standard Oil's initials, 'S' and 'O'),Don't ignore history by Robert Sobel on Barro's, 7 Dec 1998 to which the other Standard Oil companies would later object. Standard Oil of New Jersey started marketing its products under the Esso brand in 1926. In 1972, the name Esso was largely replaced in the U.S. by the Exxon brand after the Standard Oil of New Jersey bought , while the Esso name remained widely used elsewhere. In most of the w ...

Imperial Oil Refinery
The Dartmouth Refinery is a former oil refinery in Dartmouth, Nova Scotia, owned by Imperial Oil. It was located on the eastern side of Halifax Harbour, and the crude oil arrived via ship. It covered some south of central Dartmouth, with the neighbourhood around it being known as Imperoyal. History The refinery was founded in 1918, in part to meet the burgeoning needs of the First World War. It played an important role in the Second World War, providing the fuel for much of the Allied North Atlantic convoys. The site was originally the site of Fort Clarence, one of the eighteenth-century forts guarding the harbour against attack. On July 21, 2011, the refinery was temporarily shut down due to damage sustained during an electrical storm. Scheduled maintenance was moved ahead to coincide with the repairs. Meanwhile, some fuel suppliers in the refinery's service area closed down due to a lack of supply and the wholesale price for gasoline in New York rose marginally. Clos ...

Ground Level Ozone
Ground-level ozone (O3), also known as surface-level ozone and tropospheric ozone, is a trace gas in the troposphere (the lowest level of the atmosphere of Earth, Earth's atmosphere), with an average concentration of 20–30 parts per billion by volume (ppbv), with close to 100 ppbv in polluted areas. Ozone is also an important constituent of the stratosphere, where the ozone layer (2 to 8 parts per million ozone) exists which is located between 10 and 50 kilometers above the Earth's surface. The troposphere extends from the ground up to a variable height of approximately 14 kilometers above sea level. Ozone is least concentrated in the ground layer (or planetary boundary layer) of the troposphere. Ground-level or tropospheric ozone is created by chemical reactions between NOx gases (oxides of nitrogen produced by combustion) and volatile organic compounds (VOCs). The combination of these chemicals in the presence of sunlight form ozone. Its concentration increases as height above s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambton County
Lambton County is a county in Southwestern Ontario, Canada. It is bordered on the north by Lake Huron, which is drained by the St. Clair River, the county's western border and part of the Canada-United States border. To the south is Lake Saint Clair and Chatham-Kent. Lambton County's northeastern border follows the Ausable River and Parkhill Creek north until it reaches Lake Huron at the beach community of Grand Bend. The county seat is in the Town of Plympton-Wyoming. The largest city in Lambton County is Sarnia, which is located at the source of the St. Clair River at Lake Huron. The two Blue Water Bridges cross the river at Sarnia, connecting it to Port Huron, Michigan. The bridges are one of the busiest border crossings between the two countries. The river is also traversed by one passenger ferry further south, and a rail tunnel, also at Sarnia, runs underneath it. The CN rail tunnel accommodates double stacked rail cars. Along with Sarnia, the population centres in Lambton Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smog
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words ''smoke'' and '' fog'' to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions. Smog is often categorized as being either summer smog or winter smog. Summer smog is primarily associated with the photochemical formation of ozone. During the summer season when the temperatures are warmer and there is more sunlight present, photochemical smog is the dominant type of smog formation. Du ...

Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other planets, ...

Carbon Monoxide
Carbon monoxide (chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylogenetic ...

The Globe And Mail
''The Globe and Mail'' is a Canadian newspaper printed in five cities in western and central Canada. With a weekly readership of approximately 2 million in 2015, it is Canada's most widely read newspaper on weekdays and Saturdays, although it falls slightly behind the ''Toronto Star'' in overall weekly circulation because the ''Star'' publishes a Sunday edition, whereas the ''Globe'' does not. ''The Globe and Mail'' is regarded by some as Canada's " newspaper of record". ''The Globe and Mail''s predecessors, '' The Globe'' and ''The Mail and Empire'' were both established in the 19th century. The former was established in 1844, while the latter was established in 1895 through a merger of ''The Toronto Mail'' and the ''Toronto Empire''. In 1936, ''The Globe'' and ''The Mail and Empire'' merged to form ''The Globe and Mail''. The newspaper was acquired by FP Publications in 1965, who later sold the paper to the Thomson Corporation in 1980. In 2001, the paper merged with broadcast ...
