Nickel And Its Effects On Our Planet

Arsenic is rapidly cleared from the body and often is undetectable after only a few hours. However, continuous exposure to arsenic can result in severe poisoning and multiple organ involvement. Arsenic is one of the most common pollutants and contamination of food and water is widespread and consumption is significant. Recent studies have linked a correlation between dermatofibromas and arsenic. One study suggested that the combination of dermatofibromas and arsenic caused the development of breast cancer. However, the exact cause in development of dermatofibroma is unknown but damage to the endothelial cells is commonly caused by arsenic exposure. Instead of the arsenic being excreted in eccrine glands, arsenic becomes deposited in a concentrated area of the body and built over a period of time causes the growth and development of

In Marietta, Ohio, a steel plant called Eramet has been pumping the air full of a toxic chemical called Manganese. The chemical is known to cause health problems, particularly damaging to neurochemical and motor function. When a study confirmed that manganese concentrations in the area were much higher than

defense system it can alter a cell's genes to make it become a cancerous cell.

Arsenic has been shown to cause cancer and deaths. However, the element is multifaceted because in other studies it has been shown to have a healing effect. Be that as it may, the component is clearly exceptionally equivocal in light of the fact that in different reviews it has been appeared to have a recovering impact.

The next piece of evidence showing environmental determinants to health is the air samples taken from the African American community’s residents. Moreover, the air samples taken from the Norco residents living close to the refinery show higher levels of toluidine and benzene, known cancer and disease causing chemicals, than averages from the rest

The Natural Step provides a framework for considering the effects of materials selection on human health. Robèrt suggested that many human health problems, particularly those of children, result from materials we use in our daily lives. The extraction of resources such as fossil fuels and metal ores from the planet’s crust produces carcinogens and results in heavy metals entering the earth’s surface biosphere

Various speculations of how cancer is produced have been looked into through numerous years and

These include improving the extraction processing to lower exposure for workers and consumers, and also a main emphasis on the defence of the eco system. Nickel in small doses is essential for health. However, over exposure can be dangerous to human health with it showing a large correlation to the development of certain cancers, sickness, lung embolism, respiratory failure and other disorders. Legislations on packaging of products are also in effect allowing the consumer to be informed of the possible health effects. A limit on emission levels for various products have also been introduced, regulating the exposure to protect the

Marr, Hansen, Meyer, Cacela, Podrabsky, Lipton and Bergman (1998) investigated the effects of cobalt and copper to rainbow trout (Oncorhynchus mykiss). These two are heavy metals that are obtained from mining operations. Marr et al. (1998) focused on the effects of cobalt but in order to simulate environmental conditions, such as run offs caused by mining operations, they included copper in their study. Due to insufficient toxicity studies of cobalt and copper, they deemed it significant to find the acute toxicity and the joint toxicity of these two metals. They cultivated rainbow trout that were soon separately grouped to be exposed to cobalt, copper and cobalt-copper for 14 days. They accounted for mortality of the fishes during the exposure period.

The NCI reports, "At least two­thirds of the cases of cancer are caused by environmental

EPA established a reference risk level for carcinogens of 1*10-4; it means that the risk associated with a health problem is the 1 in 10,000. It is assumed that a person exposed to the minimum carcinogenic dose of a chemical can develop cancer; therefore, we can calculate the minimum carcinogenic dose from equation (3) by using the reference risk level of 1*10-4 and cancer slope factor of each chemical; cancer slope factor defines the relationship between a specific chemical and the likelihood of developing a tumor after exposure to such a chemical and is used to predict cancer at a specific dose. To calculate the minimum carcinogenic dose, weight-of-evidence classifications and an average adult body weight of 70 kg are used. Weight-of-evidence classifications show the likelihood of a chemical to be a carcinogen. While the EPA uses letters A (carcinogenic to humans), B1 (likely to be carcinogenic; limited human evidence), B2 (likely to be carcinogenic; little or no human evidence), C (possibly carcinogenic; little animal evidence), D (not classifiable), and E (evidence of no carcinogenic effects), Forman (1993) quantified weight-of-evidence and assigned likelihood values to each letter: A = 1.00, B1 = 0.84, B2 = 0.67, C-B2 = 0.51, and C = 0.34. The following equation can be used to calculate hazard dose of a

The effect of copper exposure upon mine workers has been studied to a great extent. The mechanisms by which the body incorporates copper are relatively well understood. There are two genetic disorders, Wilson’s Disease (WD) and Menkes Disease (MD) that result from mutations in enzymes that are involved in the transport of copper into cells of the body (Figure 3, Ref’s

Workplace exposure to certain chemicals: Exposure at workplace to certain chemicals used in the dry cleaning and metal working industries increase person’s risk of pancreatic cancer.

Exposure to asbestos, metal or coal gas processing, and radiation like radon gas influences lung cancer,

The piece ‘Inhale’ seems to be about how the Earth’s air is becoming polluted with the variety of gasses seeping from trucks, factories, and the various cosmetic products we use on a daily basis. Contaminating the air until it becomes harder for us to breathe, such as Japan were the high air pollution makes it difficult to breathe. Speaking from my own evaluation and observations, the painting seems meant for adults considering that most of the human beings in the piece of art look to be adults and adults are the main factor in the pollution of our air. I suppose that this piece was produced to strike fear into humanity or at least some uncomfortableness at seeing a glimpse at what may be our future, such as wearing masks over our nose and
