Toxicity Assessment

In infants can occur apnea, pause in the rhythm of his breath. Coughing can cause the patients to vomit and to lose consciousness, abundant vomiting can also cause dehydration (Centers for Disease Control and Prevention.) When adults get B. pertussis infection, it is not as severe as when children get it (Konkel.) Pertussis, even if it is treated well, sometimes there can be serious consequences, for example, pneumonia sometimes appears or bleeding from the nose and mouth, due to coughing. In infants, asphyxia is very common, therefore, it is recommendable for infants under a year old need to be hospitalized in order to have an especial treatment (Centers for Disease Control and

Some have had asthma attacks, caused babies to die because of the breast milk that they were taking in. Most pollution & asthma attacks come from people in minority neighborhoods. Environmental racism can lead to people having asthma attacks because of air pollution from factories, can harm food & water minority people eat & drink, and also can make governors and presidents fight for minority people in minority

Copper is dangerous in large areas as it can be poisonous. Copper does not react with water. Copper corrodes when is exposed to air. Oxidation can occur when water and carbon dioxide combine to make hydrated copper carbonate. How copper impacts the society Copper is a very vital part of the society.

We can view these chemicals on the table below: One of the chemicals of note is Dioxin that is highly carcinogenic.

One of the most important causes of Nile contamination is discharging of industrial facilities (Mohamed et al., 1998). Factory waste contains heavy metals such as, Zinc (Zn), Cadmium (Cd), Lead (Pb) and Copper (Cu), which cause toxicity. In this essay, the discussion will point to Nile contamination as a controversial issue and highlight some health problems which occur as consequences of using polluted water in Egypt. Likewise, the essay will raise some scientific methods to determine the percentage of heavy metal in water supported by example. Then it will suggest some chemical technical solutions to reduce the percentage of heavy metals in Nile and reuse it again for many purposes.

Introduction Selenium is an essential mineral that can be found as number 34 in the periodic table. Selenium does not only contribute to human body but also in the electricity industry. Humans require and acquire selenium in their daily diets. For some may not know that selenium contributes greatly to the human body. The human body has a recommended dietary allowance and also a tolerable upper intake level of selenium needs.

Common areas to be exposed to secondhand smoking is in public places like that mall or even in the car. Second Hand smoking can cause cancers, asthma attacks, and even emotional changes like depression. (“Health Risks”) “Some studies have linked SHS to mental and emotional changes, too. For instance, some studies have shown that exposure to SHS is linked to symptoms of depression.” (“Health Risks”) “Secondhand smoke can also trigger asthma attacks, make asthma symptoms worse, and even cause new cases of asthma in kids who didn’t have symptoms before.” (“Health Risks”) “In the United States

Nitroaromatic compounds are the major group of pollutants because they enter into environment in large quantities, are toxic and resistant to degradation and bioaccumulate. Nitroaromatics such as nitrobenzene, nitrotoluenes, nitrophenols, nitrobenzoates and nitroanilines are extensively used in industry for the manufacture of pesticides, explosives, dyes, plastics and pharmaceuticals. There are reports of widespread contamination of soil, water and atmosphere by nitroaromatic compounds. Nitrotoluenes are used in the large scale manufacture of explosives such as 2,4,6-trinitrotoluene (TNT), which has led to the contamination of soil. Environmental pollution by Nitroaromatic compounds Nitroaromatics are stable, persistent, toxic and mutagenic and many of them are suspected or recognized carcinogens (Lotufo et al., 2009; Marvin-Sikkema and de Bont 1994; Nishino et al., 2000; Padda et al., 2003; Purohit and Basu 2000; Reiger and Knackmuss 1995).

The explosion left him in the hospital with severe burns, missing his front teeth and a chunk of his tongue. He switched to e-cigarettes to try and quit smoking. E-cigarettes could lead teens on to trying tobacco. E-cigarettes are highly addictive and do contain dangerous chemicals such as nicotine, in the e-liquid. Nicotine is highly addictive, it could cause cardiovascular disease, birth defects, and poisoning.

It is considered a life-saving mineral by the united nations as it is both of biologic and public health importance. Natural levels of zinc without human influence typically ranges between 10 and 300mg/kg in soil, rock and rivers, and has an average of 70mg/kg in the Earth’s crust. Certain locations have high concentrations of zinc due to the natural process of erosion that transports zinc to such areas, as well as the influence of human activities that propagate its release to the environment www.zinc.org/environment/. For instance, activities like mining, the use of zinc in industry, and its application in agriculture and medicine (24). Environments that have either too low or very high concentrations of zinc have detrimental effects to living organisms.
