The United States should build more Nuclear power plants‚ they are good for the environment unlike coal burning power plants which are major producer of carbon dioxide and contributor of mercury in our waterways; they produce a lot of energy‚ they don’t produce any air pollution or greenhouse gases‚ and the little pollution they create can be safely stored and carefully contained. Many people are suspicious of this new technology simply

SMALL-SCALE MINING (Lives at risk in the Philippine Gold Mines) INTRODUCTION Gold is the number one mineral produced by the Philippines in value terms. Although total local production was low relative to world production‚ it ranked 2nd to Africa in gold production per unit land area in 1988 and ranked 29th as top gold producer in 2002(Israel and Asirot 2002). In the year 2002–2007‚ the Philippines’ gold production increased by 8.2%. This contributed an average of 2% gross domestic product (GDP)

1977). The both cases were attributed to the methyl mercury that was generated in the process for producing acetaldehyde using mercury as catalyst. Methyl mercury had accumulated in fishes and shellfishes and those who ate them had been poisoned with it. These cases of the poisoning with organic mercury poisoning were the first to take place in the world through the food chain transfer of its environmental pollution. The cases of organic mercury poisoning that had been known prior to Minamata Disease

such as nitrogen‚ mercury‚ and carbon dioxide emitted by certain power plants. Compact fluorescent light bulbs (CFLs) are an important tool in efforts to reduce pollution and address climate change. Is there mercury in CFLs? CFL bulbs contain up to 5 milligrams of mercury‚ the amount that would cover the tip of a ballpoint pen‚ ‚ as compared to older home thermostats and mercury fever thermometers‚ which contain from 500 to 30‚000 milligrams. If a CFL bulb breaks‚ the amount of mercury released can evaporate

The cause of autism is unknown but some blame vaccinations like MMR (measles‚ mumps‚ and rubella) and the influenza vaccination on the cause because they both contain thimerosal‚ which is a mercury based preservative (CDC Website‚ 2009)‚ is a compound that kills or prevents the growth of microorganism‚ such as bacteria or fungi (FDA Website‚ 2007). The unknown onset of autism causes the argument of whether or not thimerosal is the contributor

Water Traps and Pigtail Siphons A water trap is a device that allows gas and air to pass but holds back water. Pigtail Siphons Industrial factories utilize steam as a pressurized fuel for energy consumption. This steam needs to be regulated by a gauge‚ but the gauge must have a way of being safe from the powerful heat and pressure of the steam itself. This is where pigtail siphons (or siphons) come in. Function Pigtail siphons are looped pipes filled with water that are placed in piping configurations
