concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg). A mechanic in an automotive repair shop is exposed to the following carbon monoxide levels over an 8 hour shift. Calculation for TLV and PPM TLV in mg/m^3 = (TLV in ppm) (gram molecular weight)/24.45 *24.45 is the molar volume of air in liters gram molecular weight of CO = 28.0101 g/mol PPM = x(%) = x(ppm) / 10000

Introduction “The Ontario Fire Code Article 2.6.3.4.” states open air burning shall not be permitted unless approved‚ or unless such burning consists of a small confined fire‚ supervised at all times‚ and used to cook food on a grill or barbecue." The term ’approved ’ means approved by the Authority Having Jurisdiction (AHJ) which is the local fire department. The Ontario Fire Code dose not regulate the barbequing on the balconies‚ however‚ some cities prohibit it. For example‚ city of Guelph

Carbon‚ an element discovered before history itself‚ is one of the most abundant elements in the universe. It can be found in the sun‚ the stars‚ comets‚ and the atmospheres of most planets. There are close to ten million known carbon compounds‚ many thousands of which are vital to the basis of life itself. Carbon occurs in many forms in nature. One of its purest forms is diamond. Diamond is the hardest substance known on earth. Although diamonds found in nature are colorless and

fuels‚ substandard emission techniques‚ and an ever growing population all play an intricate role of raising Earth’s overall temperature. Each can be linked through one key adversary‚ carbon dioxide. Rising CO2 levels are almost the sole reason temperatures are rising at such an alarming rate. Aside from water vapor‚ carbon dioxide is a chief ingredient in our Greenhouse Effect stew. It’s everywhere. It emits from our cars‚ it flies from our smokestacks‚ and it empties from our lungs. All of Earth is

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic
