Volcanic Dust Hydrogen Sulfide Smoke Secondary pollutants form when primary pollutants react in the atmosphere, such as the presence of direct sunlight. These secondary pollutants are ozone, nitric acid, peroxyacyl nitrates and toxic organic compounds such as formaldehyde. It is the mixture of these primary and secondary pollutants that form photochemical smog. Photochemical smog is more prolific in warmer climates with areas of modern industry and a number of automobiles. Smog isn’t a
Silanetriol, Keratin Amino Acids, Polysorbate 80, Panthenol, Caryocar Brasiliense (Pequi) Seed Oil, Quaternium-52, Benzyl Salicylate, Limonene, Hexyl Cinnamal, Linalool. Hair spray contain many VOCs (volatile organic compounds) which cause serious damage to the ozone such as ozone depletion. These compounds, including methane as known as CFC (Chlorofluorocarbon), have been serious factors causing global warming. CFC was developed in the 1930s under the trade name Freon. “CFC was supposed to be wonder
For this research paper, I chose to discuss the Louisiana air quality and its effects on the community. I was raised here in Baker, Louisiana which is north of Baton Rouge. Growing up I noticed something very striking and odd. We are overly exposed to chemical plants and their outputs. Driving around Baton Rouge at night and seeing a distant flame I often wonder what it really was. I wonder how this was affecting the community. How was this affecting our health? Upon doing research, I discovered

industrial smog. However, the burning of fossil fuels like gasoline can create another atmospheric pollution problem known as photochemical smog. Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different and hazardous chemicals known as secondary pollutants. Development of photochemical smog is typically associated
order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substances. The procedure for this laboratory assignment are on the following pages. 3) Separation of Carboxylic Acid, a Phenol and a Neutral Substance The purpose of this acid/base extraction is to separate a mixture of equal parts of benzoic acid(strong acid) and 2-naphthanol(weak base) and 1,4- dimethoxybenzene(neutral) by extracting from tert-butylmethyl ether(very volatile).The goal of this experiment
enthalpy changes of combustion of different alcohols What are alcohols? ================== Alcohol is the common family name for the hydrocarbon group alkanols. At least one of the hydrogen groups is replaced by an OH group. They are all organic compounds. The general formulas for the alcohols are: CnH(2n+1)OH Where n represents a number. The first and simplest member of the alkanols family is methanol. Its molecular formula is CH3OH. You can now see that each member of the alcohol family
itself in the title. Before her lover has a chance to speak he is suspect because "porphyria," as defined by Reader’s Digest Illustrated Encyclopedia Dictionary is: A hereditary disease involving disturbance in the metabolism of porphyrins [organic compounds that provide the foundation structure for blood in animal tissues] and producing symptoms of mental confusion, neuritis, and abdominal pain. (1319) The title suggests that Porphyria’s lover is not even revealing the name of the woman he strangles
and medicinal purposes. Solutions containing more than about 8 percent hydrogen peroxide are corrosive to the skin. First recognized as a chemical compound in 1818, hydrogen peroxide is the simplest member of the class of s. Of the several processes of manufacture, the principal ones involve reactions of oxygen from the air with certain organic compounds, especially anthraquinone or isopropyl alcohol. Major commercial grades are aqueous solutions containing 35, 50, 70, or 90 percent hydrogen peroxide
The vastness of space holds many mysteries. One such mystery has puzzled scientists for hundreds of years; that of the abiogenesis of life. Exactly how can such complex organic structures blossom from nothing more than large chunks of elementally simplistic rock? On June 30th, 1908, another of these universal mysteries (although one that can be considered philosophically smaller) released 10-15 megatons of energy in a blast that devastated large swathes of the Tunguska forest region in Russia. Many
Proteins Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word “proteies” or “primary”. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions
Mercury: A toxic poison No other metal better illustrates the diversity of effects caused by different chemical species than does mercury. On the basis of chemical speciation, there are three forms of mercury: elemental, inorganic, and organic compounds. The major source of mercury is the natural degassing of the earth's crust, including land areas, rivers, and the ocean, and this source is estimated to produce on the order of 2700 to 6000 tons per year. The total man made release into the
Everything You Need to Know about Vitamins Vitamin, any of the organic compounds required by the body in small amounts for metabolism, to protect health, and for proper growth in children. Vitamins also assist in the formation of hormones, blood cells, nervous-system chemicals, and genetic material. The various vitamins are not chemically related, and most differ in their physiological actions. They generally act as catalysts, combining with proteins to create metabolically active enzymes that
Isolation of a Urea Degrading Bacteria Introduction Urea was the first organic chemical to be synthetically produced1, previously it was thought that only living creatures could produce organic compounds Urea is naturally produced by the kidneys as waste from the degradation of amino acids. It is because of this that urea is commonly found in soils and is a useful nutrient source for bacteria that are able to utilise it, such as, Helicobacter pylori, Klebsiella pneumonia, all species of Proteus
Structure and Function of Lipids in Plants and Animals Lipids are the name given to a mixed group of organic compounds. The elements Hydrogen, Oxygen and Carbon are always found in Lipids. The difference between them and Carbohydrates is that they have a lower proportion of Oxygen in the molecule. Lipids are insoluble in water, but they are soluble in organic solvents, such as ether, acetone, chloroform or benzene. There are several parts in the group of Lipids: o fats and oils,
the founding of the nation. The buyout of Times Beach and some 50 other sites in Missouri by the government beginning in 1983 was prompted by the largest civilian exposure to dioxin in the United States. Dioxin is a member of the family of organic compounds known as aromatics. Dioxin is the shorthand that refers to a family of polychlorinated dibezodioxins or PCDDs. Their general structure is that of two chlorinated benzene rings joined by two oxygens, hence dioxin. Dioxin is not made intentionally
importance in the field of organic and inorganic chemistry. The functional group can therefore readily identified by their characteristics frequencies of absorption. This makes the IR spectroscopy the most useful means to obtain the structural information about the organic and inorganic molecules as it measure easily and quickly the atoms vibrations so in this result we are able to indentify the functional group in a molecule. When it is passed through any of organic compounds some of the radiations
more disadvantages to the introduction of the new technology than one might anticipate. The following first explores the effects of vitamin a deficiency and then the arguments of the opposition and supporters' responses to it. Vitamin A is an organic compound that is needed in small amounts in the human body; however a deficiency in this micronutrient can lead to problems and illnesses (3). The vitamin is found naturally in many plant and animal foods in the forms of retinal in animals and carotene
are larger, because they have a higher intensity of light I have chosen the above hypothesis, because plants cannot grow or live without photosynthesising. Photosynthesis is the process of converting simple organic compounds (CO2 and H2O) into more complex organic compounds (glucose and oxygen), in plants: + Light [IMAGE]- Carbon dioxide + water glucose + oxygen + Light [IMAGE]- 6CO2 + H2O C6 H12O6 + 6O2 All plants photosynthesise, they all have chloroplasts
