+ Damage from fluorescent bulbs

Fluorescent bulbs, with curly shapes, distinct twist, look very nice, they are said to have the advantage of saving power consumption and reduce pollution. However, each fluorescent bulb contains about 5 mi re - li - grams of mercury. Despite that, this is just a tiny amount, but it's the 5 mi - li - gram of mercury is enough to contaminate about 22680 liters of drinking water, as recommended by the Environmental Protection Agency United States (EPA).

As long as fluorescent bulbs are still working well, meaning that the amount of toxic mercury is still contained in the bulb, then it will not cause problems, but when the fluorescent lamp is damaged, we will become real threats to the environment and human health if they are not cleaned and properly disposed of. 

1 Fluorescent Lamps detrimental to health 
If there's one fluorescent bulb is broken for any reason whatever, it means that 5 mi - li - grams of mercury are toxic emissions into the environment, and directly affecting the health of those who accidentally come into contact with it. As recommended by the Environmental Protection Agency United States (EPA) mercury exposure at low (less than 5 mi - li - g) can cause tremor, mood changes, insomnia, muscle fatigue, and headaches. If exposure at high doses or prolonged exposure can lead to dull, personality changes, hearing loss, memory loss and even destruction of chromosomes; nerve cells, brain, and kidneys will also severely damaged. This toxic substance mercury also affects directly to the nervous system of fetuses and children. 

Information of Economic Research found that 0.5 milligrams of mercury in an energy-saving bulb can pollute 180 tons of water and dat.Nam 2008 energy saving light bulbs have been listed in China of the hazardous waste. 

Most people only know about the use of energy saving bulbs that do not understand the dangers of toxins in it. Especially when broken power-saving light bulbs emit mercury adequate environmental devastation human nervous system. 

Previously, a group of scientists in Berlin (Germany) also issued a warning to consumers about the harmful effects of energy saving light bulbs. Because the bulbs contain mainly fluorescence when turned on can produce dangerous toxins like phenol, naphthalene and styrene, and even cause cancer. 

2 The danger from fluorescent bulbs for environment 
Environmental Protection Agency United States (EPA) states in the United States alone, more than a billion fluorescent lamps save energy is thrown into the trash every year. In some areas, some fluorescent lights save energy are broken. The result is a significant amount of mercury from broken bulbs is emitted to air, water and land. Mercury can leak into the water system or floating in the air to the surface of the soil, so mercury toxic substances present in: the fish that we eat and the water we drink . 

Scientists at Lenntec company (the company handling air and water, with headquarters located in Delft, The Netherlands) explained that the majority of agricultural fertilizers contaminated mercury is absorbed by theloại trái cây và rau chúng ta ăn hàng ngày. The food and drinks for livestock can also be contaminated mercury and then humans eat the meat of animals infected with mercury.

3 danger to animals from fluorescent bulbs 
  Animals are raised on farms and wildlife also affected by mercury. Mercury released into the water and penetrate into the body of fish and other animals when they drink water contaminated mercury. The findings made ​​by scientists working at the company Lenntec show that mercury exposure is related to the ability to change DNA and miscarriage in animals, as well as destroying body parts of animals such as the kidneys, stomach and intestines. 

To avoid the dangers caused by fluorescent bulbs save energy, it is important to handle correctly broken bulbs. Many State in the United States, providing recycling program for fluorescent lamps save power corrupted. 

Users should contact local authorities or waste management agencies for more information. If a fluorescent bulb breaks, Environmental Protection Agency, United States (EPA) recommends that you should open a window and leave the room for at least fifteen minutes. You should turn off the heating and air conditioning system. Absolutely do not use a vacuum or broom to clean up the spilled liquid from the bulb, by doing so can spread more mercury into the air. You carefully remove the glass pieces and put them in a glass jar with metal lid or in a sealed plastic bag. Use sticky tape to remove small debris. Put the pieces in jars, bags, and carefully packed.
