Description
Technical field
The present invention relates to a kind of detection reagent, be specifically related to a kind of Indoor Air Benzene ethene and detect reagent and preparation method thereof.
Background technology
In recent years, China had formulated the standard of a series of relative chamber environment in succession, from the use of building and ornament materials, to indoor air pollutants containing quantitative limitation, comprehensively carried out strict monitoring to indoor environment, to guarantee that the people's is healthy.Therefore, people often think that modern living conditions are in continuous improvement, and indoor environmental pollution is controlled.Actually this is not so, and people also reach far away enough understanding to the harm of indoor environmental pollution.
Should see, while China's economy develops rapidly, due to the indoor environmental pollution that building, decorations, furniture cause, become the large killer affecting health of people.According to the data that Chinese indoor air chemical pollution center provides, the death toll that exceeds the quata that China is caused by room air pollution every year can reach 11.1 ten thousand people, and the outpatient service number that exceeds the quata can reach 220,000 person-times, and the emergency treatment number that exceeds the quata can reach 4,300,000 person-times.Serious indoor environmental pollution not only causes damage to health of people, and causes huge economic loss, and only the economic loss that causes because of indoor environmental pollution health risk of China is just up to 10,700,000,000 dollars nineteen ninety-five.
Find after expert investigation, indoor decoration uses the material containing objectionable impurities can aggravate indoor pollution level, and these pollutions are larger on the impact of children and women.Related statistical shows, because of the infection of the upper respiratory tract, the lethal children died about have 2,100,000 every year in current China, wherein the cause of the death of more than 100 ten thousand children is directly or indirectly relevant with room air pollution, particularly some newly-built and newly-decorated kindergartens and family room's environment pollution very serious.There is increase trend in the big cities such as Beijing, Guangzhou, Shenzhen, Harbin in recent years leukemia children, and to stay in the room excessively fitted up be wherein one of major reason.
According to the regulation of GB50325-2001 " covil construction indoor environmental pollution controls specification ", require to detect formaldehyde, benzene, the indoor main pollution such as total volatile organic compounds (TVOC), ammonia, radon.TVOC be three kinds affect indoor air quality pollute in affect comparatively serious one.Under TVOC refers to room temperature, saturated vapour pressure has exceeded the organism of 133.32pa, its boiling point is at 50 DEG C to 250 DEG C, and the form can evaporated at normal temperatures is present in air, its toxicity, pungency, carcinogenicity and special odor profiles, skin and mucous membrane can be affected, acute lesion is produced to human body.And styrene to belong in TVOC a very important Testing index.Indoor Air Benzene ethene can affect human body health, and its source mainly contains the following aspects: mainly discharged by building materials, detersive, paint, aqueous coating, bonding agent, cosmetic crystalline substance and washing agent etc.
Styrene harm shows as: have stimulation and anesthetic action to eye and upper respiratory tract mucosa.Acute poisoning: during high concentration, causes the stimulation of eye and upper respiratory tract mucosa immediately, there is ophthalmodynia, shed tears, runny nose, sneeze, pharyngalgia, cough etc., then headache, dizziness, Nausea and vomiting, malaise etc.; Severe patient can have dizzy, lurch.When eye is by styrene liquid contamination, can causes and burn.Chronic Effect: common neurasthenia syndrome, have headache, weak, nauseating, anorexia, abdominal distension, melancholy, forgetful, refer to quiver.Have spread effect to respiratory tract, Long Term Contact causes obstructive lung pathology sometimes.Pachylosis, chap and thicken.
Therefore, we often need to carry out styrene-content detection to the environment of surrounding, are unfavorable for healthy environmental factor to eliminate.
