Many populations have been exposed to environmental lead, which is a powerful neurotoxin that negatively impacts the health and mental state of children and adults. Interestingly, the article titled “Could Early Lead Exposure Contribute to Crime and Delinquency?”, written by Dr. Michael Pittaro, provides some statistical data and valuable information about Dr. Pittaro’s fascination about crime, and the contributing factors that cause individuals to participate in illegal activities (Pittaro,…

One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire. Through its uses and toxicity, lead affected the classical era in a drastic way.…

In 1991, a mysterious body was found in the Alps between Austria and Italy. Police were brought in, a murder investigation begun, and identification attempted. Yet, this proved to be more complicated than previously anticipated when the investigators realized that the man from the ice, Ötzi, died 5300 years ago during the Copper Age. Ötzi died in about 3200 BC, his age is estimated to be between forty-five and fifty years old. He was 5’2 and weighed about 100 pounds. His last meal was red…

allegations that they were responsible for damages based on their conduct. The Defendant demurred in part, on the grounds that the district court lacked subject matter jurisdiction in the matter. The Defendant also operated a secondary lead refining and smelting plant. It is the Plaintiff’s belief that the Defendant knowingly misrepresented the facts to its employees, refusing to acknowledge that their work environment was reasonably safe. The Plaintiffs also alleged that the devices and…

4000 BCE and lasted until 1500 BCE. It was distinguished by the use of bronze. The Bronze Age was a period of time after the Neolithic Age when ancient humans upgraded from making tools out of stone and hunting and gathering their food to mining and smelting copper and tin in order to make bronze tools, weapons, and farm equipment and learning about agriculture. This gave them the opportunity to have extra food to store and enabled them with the possibility of settling down and starting a family…

• The Yangshao culture was first excavated in 1921, it lasted to c. 2700B.C.E. - Farmers grew millet, wheat, and rice, and domesticated pigs, dogs, goats and perhaps horses. - They lived mostly in river valleys, and villages were often surrounded by walls for protection. • Soon larger political units were created and the Xia, Shang, and Zhou dynasties came to be. - The Traditional chronological dating suggests that one succeeded another. - Capitals were frequently shifted…

water solution then reacts with chlorine or fluorine and precipitate. There are two types of copper mining. Surface, an open-pit surface mining or strip mining. Subsurface, shaft mine and slope mine. After the ore is dug out, it is processed through smelting. The reddish-orange metal is a ductile metal, a property of a material that permits it to be stretched into a wire without breaking. Copper is also malleable, the property of a material that permits it to be flattened without shattering.…

as this accounts for 80% of Indium consumption. Though Indium is a valuable resource in today’s society, the consequences of processing and disposing of this element poses an overall threat to the environment. Through an expensive process called ‘smelting,’ Indium is extracted through Zinc, Tin, Lead and Copper ores. Aside from knowing the origin of this metal, the key to further comprehending the…

(“Canadian”). Many worry that some sort of chemical spill could contaminate the meager amount of usable water that the communities have (Ross). The process to produce high-grade copper includes smelting at temperatures of 200 degrees Celsius to remove sulphide, oxides, and other contaminants from the pure copper. Smelting the copper emits vast quantities of sulphur oxides and other harmful gases into the air. The strong winds circulate the harmful pollutants furthering the extent of the…
