Lost hand to break the glass thermometer, how to deal with? Many people can not say the exact answer. A month from the official entry into force of the Minamata Convention on Mercury, mercury pollution is still a distant concept for some people.
On January 19, 2013, the United Nations Environment Program adopted the "Minamata Convention on Mercury", which is an international convention to control and reduce mercury emissions on a global scale and provides detailed provisions on the specific limits to reduce mercury Environment and human health, so far there have been 128 signatories and 55 signatories. Last August, our country became the thirtieth ratifier of the Convention.
Mercury pollution threatens human health and human emissions are the largest sources
Mercury commonly known as mercury, itself and its compounds are toxic, can enter the human body through the respiratory, skin or digestive tract and other ways to cause damage. Mercury and mercury-containing compounds are released into the environment causing environmental mercury pollution.
Studies have shown that mercury released into the atmosphere as a gas can invade the human body through the respiratory and skin exposures. The health effects of the human body are mainly manifested as chronic multiple-system damage caused by low-dose, long-term exposure. Among them, the main damage to the nervous system and kidney, the reproductive system, immune system, respiratory system, digestive system, also has a strong toxicity.
Mercury released into water and soil, under the action of microorganisms, can be converted into more toxic methylmercury, benzene, mercury and dimethylmercury, causing mercury pollution in water bodies and soil mercury. It can also be deposited in organisms through a series of biotransformations and eventually transferred to the human body through the food chain, threatening human health. Minamata disease is a typical mercury poisoning illness caused by food intake.
Thermometer broken how to do?
Mercury is the only liquid metal at room temperature. Once the articles containing it are broken, the mercury evaporates quickly and the sphere rolls down. At this moment, turn off all indoor heating devices and open the windows for ventilation.
Wear gloves to collect mercury as soon as possible. The method of collection is to stick the spilled mercury on the ground with a small stick of wet cotton stick or tape and put it in a vial that can be sealed, such as a plastic bottle such as a drink bottle, and add a small amount of water to the bottle State "discarded mercury" and other logo texts, to the community residents waste management staff or sent to the environmental protection department to deal with. Do not pour the collected mercury into the sewer to avoid pollution elsewhere.
Mercury, which can not be completely collected on the ground, can be sprinkled with mercury powder (sold in general pharmacies) in places where mercury falls. Mercury in the face of sulfur, the formation of volatile mercury sulfide compounds, to prevent the volatilization of mercury into the air, so mercury pollution does not exist.
Mercury evaporates into a gaseous state at room temperature and is easily inhaled into the respiratory tract and causes poisoning. Therefore, it is best to wear a mask when handling scattered mercury. If the wound met with mercury, should go to the hospital's poisoning prevention and control department to check to prevent poisoning.
Break mercury mercury thermometer at home after treatment more timely, clean, home ventilation conditions are better, it will not cause mercury poisoning.
For safety, it is recommended that you choose electronic thermometer temperature measurement, quick and easy, non-toxic mercury-free products using environmentally friendly materials, the human body without any radiation and injury.
