Indiana Harbor, Indiana
The Indiana Harbor and Ship Canal is an artificial waterway on the southwest shore of Lake Michigan, in East Chicago, Indiana, which connects the Grand Calumet River to Lake Michigan. It consists of two branch canals, the 1.25 mile (2 km) Lake George Branch and the 2 mile (3 km) long Grand Calumet River Branch which join to form the main Indiana Harbor Canal. The canal also functions as a harbor (Indiana Harbor). The outer harbor is sheltered by two bulkheads marked by lights including the Indiana Harbor East Breakwater Light. Ships enter the outer harbor from the north. The inner harbor consists of the canal itself. The entrance to the outer harbor lies near Indiana Shoals, which extend up to 5 miles offshore, where water depths are as shallow as 15 feet. In 2002, Indiana Harbor was the 45th busiest harbor in the United States, handling almost 13,300,000 short tons (12,000,000 metric tons) of cargo. Foreign trade accounted for only 500,000 short tons (450,000 met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Chicago, Indiana
East Chicago is a city in Lake County, Indiana, United States. The population was 29,698 at the 2010 census. The city is home of the Indiana Harbor and Ship Canal, an artificial freshwater harbor characterized by industrial and manufacturing activity. Situated along Lake Michigan, East Chicago is about 18 miles from downtown Chicago, Illinois and is just west of Gary, Indiana. History The land that became East Chicago was originally swampland unsuitable for farming. The state of Indiana began selling off plots of land to railroads and speculators after 1851 to fund the local school system. Settlement of the area was very slow at first, and as late as the 1890s, the city had no proper streets or public utilities. East Chicago was incorporated as a city in 1893. The city was named from its location east of Chicago, Illinois. The 1900 Census gives a total population of just 3,411, but the arrival of Inland Steel in 1903 transformed the city into an industrial powerhouse. The c ...

Clayton Mark
Clayton Mark (June 30, 1858 – July 7, 1936), one of the pioneer makers of steel pipe in the United States, was an industrialist in the Chicago area who founded the Mark Manufacturing Company in 1888, a firm for the fabrication and sale of water-well supplies and Clayton Mark and Company in 1900. In addition, Mark founded Marktown, a planned worker community in Northwest Indiana on the National Register of Historic Places. He was known for his philanthropy and civic contributions. Early years Mark, born in 1858 in Fredericksburg, Pennsylvania, was the son of Cyrus and Rebecca (Strohm) Mark. His earliest paternal ancestor in America was William Killian Mark, who moved with his brothers from Switzerland to Lebanon County Pennsylvania in 1735. Clayton moved to Chicago with his family in 1872. He was educated in the public schools of Pennsylvania and Illinois, and stopped his formal education after completing seventh grade at Brown School in Chicago. Mark's family relocated to ...

United States Environmental Protection Agency
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tr ...

Heavy Metals
upright=1.2, Crystals of osmium, a heavy metal nearly twice as dense as lead">lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals are generally defined as metals with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them. Despite this lack of agreement, the term (plural or singular) is widely used in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycyclic Aromatic Hydrocarbon
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by the combustion of organic matter—for example, in engines and incinerators or when biomass burns in forest fires. Polycyclic aromatic hydrocarbons are discussed as possible starting materials for abiotic syntheses of materials required by the earliest forms of life. Nomenclature and structure The terms polyaromatic hydrocarbon or polynuclear aromatic hydrocarbon are also used for this concept. By definition, polycyclic aromatic hydrocarbons have multiple rings, precluding benzene from being considered a PAH. Some sources, such as the US EPA and CDC, consider naphthalene to be the simplest PAH. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12 H10−''x'' Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned by United States federal law in 1978, and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taconite
Taconite () is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He believed the sedimentary rock sequence hosting the iron-formation was correlative with the Taconic orogeny of New England, and referred to the unfamiliar and as-yet-unnamed iron-bearing rock as the 'taconic rock' or ''taconyte''. Following development of high grade direct shipping iron ore deposits on the Mesabi Range, containing up to 65% iron and as little as 1.25% silica, miners termed the unaltered iron-formation wall rock taconite. The iron content of taconite is generally 30% to 35%, and the silica content generally around 45%. Iron in 'taconite' is commonl ...

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
