The main factors of this article called “Methanol--the fuel in Waiting” explains how Methanol could both have positive and negative effects in the environment and the economy. The article discusses how methanol could be another alternative to gasoline and it is a made from natural gas, which makes it easier to make and use. Methanol (see Figure 1) is that it is the simplest alcohol with a chain of one carbon atom with three hydrogen atoms attached. The characteristics of this simple alcohol are that it is a light, volatile, and flammable liquid with a unique odor very similar to ethanol. Unlike ethanol, methanol is a highly toxic chemical and should be used cautiously because it causes negative reactions when exposed to other reagents such as lead. Methanol…

A hazardous substance is defined in federal government regulations as “one that may cause substantial personal injury or illness during reasonable handling or use, including possible ingestion by children.” According to the Federal Hazardous Substances Act (FHSA), household products are hazardous if they contain substances that have one or more of the following hazardous properties:#…

“Under no circumstances should hydrogen peroxide be taken internally. If hydrogen peroxide is swallowed, drink water immediately to dilute, and contact a physician but do not attempt to cause vomiting…frequently used to treat open wounds and can be used as a gargle or mouthwash” (“Hydrogen” 2004). People might be used as mouthwash, so it may be possible for someone to swallow hydrogen peroxide. “Hydrogen peroxide itself is not combustible, but may ignite combustible materials” (“Hydrogen” 2014). Hydrogen peroxide does not light on fire, but if spilled or applied on a combustible material it can start on fire. “Inhalation of hydrogen peroxide vapors can cause irritation and inflammation of the respiratory tract” (“Hydrogen” 2004). This one of several hazards that hydrogen peroxide can cause. “Hydrogen peroxide danger hazards include that it may cause fire or explosion, harmful if inhaled, harmful if swallowed, and can cause severe skin burns and eye damage” (“Hydrogen” 2014). These are hazard classifications that include hydrogen peroxide. “Some of the inhalation hazards include sore throat, cough, dizziness, headache, nausea, and shortness of breath” (“Hydrogen” 2014). These are the effects of hydrogen peroxide being inhaled. Hydrogen peroxide has several danger hazards.…
28. Consequences of SO2, lead, O3 in troposphere, and particulates: SO2- breathing problems, visibility reduction and aggravation of asthma, damages crops, trees, soils, and lake aquatic life, corrodes metals and damages paint, paper, and leather and stone on buildings. O3- coughing, breathing problems, reduces resistance to colds and pneumonia, irritates eyes, nose, and throat, aggravates asthma, bronchitis, emphysema and heart disease and damages plants, rubber in tires, fabrics and paints. Particulates- irritate the nose and throat, damage lungs, aggravate asthma and bronchitis, shortens life. Lead- mutations, reproductive problems, cancer, nervous system damage, mental retardation and digestive and other health problems, reduce visibility and corrode metals and discolor clothes and…
Air pollution occurs when waste products mix in the air. The amount of air pollution significantly increased during and after World War II because the amount of factory use and production increased to meet military needs (Calhoun 90). There was no concern for the air and emissions' effect on health. However, after smog settled over Donora in 1948 and New York City in 1953, 1962, and 1966, many people died or became sick as the pollution lined the bronchi, damaged the respiratory system, and blurred vision (Goldman 81). The Environmental Protection Agency, or the EPA, has identified sources of pollution such as automobiles and buildings as well as seven major air pollutants, with the most common being carbon monoxide. Smog, the combination between smoke and fog, is emitted from fire, paints, and emissions from vehicles. Another common pollutant that corrodes structures is acid rain. Acid rain is any rainfall with a potential of hydrogen, or pH, of less than five. Acid rain develops when clean, normal rain, with a pH of about 5.6, reacts with carbon dioxide in the atmosphere forming acid rain. Most acid rain ranges between 4.3 and 5.0 (Trapp 5). Sulfur oxides, emitted from man-made sources such as factories, can destroy aquatic life as well as the human respiratory system. Fuel combustion is a human-caused pollutant emitted from vehicles and is composed of carbon and…
Sabra Lane, chief political correspondent for ABC Nationals radio program ‘The World Today,’ noted for her work in current affairs for commercial TV and her transition to ABC radio which provides integrity to her perspective on the Afghanistan war. She uses the term ‘sea change’ as applying to these changes in democracy practices as they are evident in modern conflicts.…
From all of the reading and research regarding DHMO and its harm it can potentially bring I began to wonder why is it still legal, and why would anyone continue it's using knowing of the damage it can do. Not only is it here on our campus, it is found almost everywhere- such as lakes, ponds, rivers, streams and the ocean itself. What…

Hydrogen peroxide is a clear and colourless substance that has a strong oxidizing characteristic. From the books, “Hydrogen Peroxide: Medical Miracle”[1995] by Douglass and “Applications of hydrogen peroxide and derivatives” [1999] by Jones, hydrogen peroxide can be used in numerous industrial and domestic applications such as a disinfectant, an oxidizer, or treatment for cancer and other diseases. However, hydrogen peroxide can be toxic when highly concentrated in the body. Hydrogen peroxide can easily breakdown into water and a single oxygen molecule through exothermic reaction, but when stored properly at low concentrations, the solution becomes stable. As a molecule, hydrogen peroxide has a double bent structure and is also a polar covalent particle. Due to these properties, hydrogen peroxide can exert the three types of intermolecular forces: Van der Waal’s force, Dipole-dipole force, and hydrogen bonding. According to “Hydrogen Peroxide Background”[2005], 3% hydrogen peroxide is denser and has a higher boiling point than water.…
Humans have many negative impacts on earth, but I chose one of the main ones that happen. Wildfires is part of nature. It plays a role in ecosystems by serving as a renewal change, but when it comes to where it is used purposely or to harm others, it can get out of control.…
Dioxins/Furans and the use of such is intoxicating & killing us like a poor man, hunting for his bargain each day & tricking us into death & ripening disintegration. Like many but not all toxins, dioxins can be an extremely deadly and dangerous byproduct; the reason why it is considered a carcinogen. It is also one of the mayor factors in the polluting of our environment, it may be small & puny but its resistance and bio radioactivity makes up for its size, increasing its potential threat immensely.…
Emphases have been placed on carbon dioxide when issues touching on the effect of greenhouse gases are discussed. Carbon dioxide has emerged as the most dangerous gas. However, contrary to this, methane gas is 30 times more intoxicating. Methane gas prevalence will continue to rise as the earth 's temperature rises. It has been established that this potent gas increases several times with each degree increase in the earth 's temperature (Princeton University, 2014, n.d).…
