Thankful FRIend Trying to get the facts out. Here ya go again. Spread the word Freepers ! Baseline. Mercury vapor should not exceed 0.0002 mg m-3 in air to stay below safe levels Concentration of Hg (g) inside Fluorescent Lamps SUMMARY OF Hg GAS CONCENTRATION IN DIFFERENT LAMP TYPES ONE FOUR FOOT T8 LAMP HAS ~ 164 MILLION times this concentration inside it ONE CFL LAMP HAS ~ 165 BILLION times this concentration inside it T8 lamp is 4 feet long and one inch in diameter One T8 typically contains 20mg of Mercury - but can range much higher Volume of a T8 lamp in ft 3 = π * r2 * L = 3.14 * (1/24)2 * 4 = 0.0218 ft3 Ft3 = 0.028 m3 Volume of T8 lamp in cubic mtr = 0.000614 m3 CONCENTRATION IN T8 LAMP of Hg (g) = 20 mg / 0.000614= 32765 mg / m3 That is 32.8 grams / m3 - that is 32765/.0002 = 163,285,000 TIMES AS HIGH! CFL CALCULATION Though proponents of CFLs often argue a single bulb only contains 5 mg of mercury, a study found it was an average. There are a number of different size and wattage CFLs so the standard 13 W lamp was used The 13 W CFL bulbs tested and broken actually ranged from 4 to 23 mg of mercury content 100% of lamps surveyed were made in China. CFLs range in volume, but typical 13W has volume of 0.58 *(1/96)2 * 3.14 = 0.000108 ft3 Ft3 = 0.028 m3 Volume of CFL lamp in cubic mtr = 3.03 x 10-6 m3 10 mg of Hg is assumed CONCENTRATION = 10 mg / 3.03 x 10-6 m3 = 33 MILLION mg per meter cubed or 3.3 KILOGRAMS per m3 That is 33,000,000 /.0002 = 165,000,000,000 TIMES AS HIGH! THAT IS 165 BILLION Yes billion HOW MUCH AIR WOULD BE NEEDED TO BRING DOWN TO SAFE LEVELS? (remember : Mercury is heavy, does not disperse, and will entrain itself into anything) One Four Foot T8 To get to .0002 mg/ m3 - 20 mg of mercury requires 100,000 Cubic Meters or 4,000,000 Cubic Feet ofAir One CFL 10 mg of Mercury will require 50,000 Cubic Meters or 2,000,000 Cubic Feet of Air SUMMARY Once released in an indoor environment , the mercury can NEVER be totally removed. What can mercury do to a person? A sudden high exposure to mercury vapor inhaled into the lung causes headaches, cough, chest pain, and difficulty breathing. It may also cause soreness of the mouth, loss of teeth, nausea, and diarrhea. It may lead to permanent lung scarring. A very high exposure to mercury can damage your kidneys. Long-term exposure to mercury can cause effects which develop gradually. It may cause shaking of the hands, eyelids, lips, tongue, or jaw. It may cause headaches, trouble sleeping, personality change, memory loss, irritability, indecisiveness and loss of intelligence. It can also cause skin rash, sores in the mouth, or sore and swollen gums. Many of these symptoms go away when the exposure to mercury stops. Your body gets rid of mercury through urine. Mercury poisoning can be treated with a medicine that pulls mercury out of your body and into the urine. This medicine is only used if mercury exposure is recent—not if mercury exposure occurred many years ago,. When the effects of mercury last for years after exposure stops, that injury is usually permanent. Get the word out to everyone you know ! Please take a these lamps out of your house immediately Be very careful with them Take them to a qualified recycling facility Then get CLEAR incandescents or LEDs if you can afford or like them Business types. LEDs are the way Power to the people! End guvmint evil now Woooooooo - hooooooooooo ! Love Big daddy
