Chemerical and Silent Spring also had the same ideas with this article. Obviously‚ ingredients in our products that we used contained lots of harmful chemicals‚ which could cause and damaged our health. For example‚ ammonia found in glass cleaner‚ naphthalene found in the carpet cleaner‚ chlorine found in bleach‚ BPA found in plastics‚ sodium lauryl sulfate found in dishwashing soap‚ or DDT found in several pesticides. These chemicals would damage our eyes‚ throat‚ liver‚ brain‚ and if we swallowed‚

It is produced by the partial maturation of kerogen or the degradation of crude oil. Crude Oil: Crude oil is a liquid at surface temperatures. It is soluble to normal petroleum solvents. It has four main groups of organic compounds: paraffin‚ naphthalene‚ aromatics‚ and resins. Natural Gas: Is a hydrocarbon gas. The major natural gases are methane‚ ethane‚ propane‚ and butane. Condensates: These are hydrocarbons transitional between gas and crude oil. Five Parameters for Hydrocarbon Accumulation

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight

collected throughout the town of DISH in August 2009 and found that benzene was present at levels as much as 55 times higher than allowed by the Texas Commission on Environmental Quality . Xylene and carbon disulfide (neurotoxicants)‚ along with naphthalene (a blood poison) and pyridines (potential carcinogens) all exceeded legal limits‚ as much as 384 times levels deemed safe .

Did you know that for every cigarette you smoke you can lose eleven minutes off your life? Smoking can not only leave you with long term affects you may not be able to get rid of but it will leave you poor and maybe dead. Mankind first came in touch with tobacco approximately eighteen thousand years ago‚ when migrant Asiatic people first intersected the Bering Strait and extended across the continents today known as the Americas‚ where tobacco is native (Gately ‚2001).
