Demand for disinfecting purifiers under world environmental pollution


First, the air pollution situation is serious, especially in China.

"Air pollution is both indoor and outdoor. It affects all of us, developing and developed countries alike."
-- Maria Neira, WHO Director, Department of Public Health and Environment
    
The WHO study found that in some parts of the world: outdoor air pollution levels have recently increased sharply; Especially in developing countries with large populations     
Air pollution has become a major threat to global environmental health. In 2012, about 7 million people around the world died from air pollution
World Health Organization; Historically, pollution in the UK has claimed tens of thousands of lives...
The massive SARS, bird flu, the "haze" in 2013 and the coronavirus epidemic in 2020 are all vividly in my mind. Whether it's sulfur dioxide, nitrogen dioxide, ozone, PM10, PM 2.5, our country is one of the highest in the world. Haikou is ranked 858 out of 1,100 cities in the world in terms of air quality. Several cities, including Beijing, Nanjing and Hangzhou, ranked outside the top 1,000. (The ranking is based on the concentration of PM10 in the air.) In 2013, only 4.1 percent of 74 cities in the Beijing-Tianjin-Hebei region, the Yangtze River Delta, the Pearl River Delta, municipalities directly under the central Government, and provincial capitals met the air quality standards. The proportion of cities exceeding the standard is as high as 95.9 percent.
    
In 2013, only three of the 74 cities -- Haikou, Zhoushan and Lhasa -- met the air quality standards. ------

In 2013 Annual Bulletin of the State of China's Environment (180 households were sampled from 1,800 households in typical villages of Hunan, Hubei, Sichuan and Gansu for testing), the indoor CO, SO2 and PM2.5 pollution of farmers was serious: the highest daily average concentration of the three pollutants was 8, 38 and 4 times higher than the national standard, respectively. More than half of the households exceed the standard of CO, SO2 and PM2.5, among which the SO2 of coal users reaches 81.95%. (Xiang Li, "Transactions of the Chinese Society of Agricultural Engineering" Vol. 22, Suppl. 1, October 2006) The indoor PM10 pollution of residents in Shenzhen city is relatively serious, and the over-standard rate of PM10 is 89. 3%. Beijing Institute of Labor Protection, the detection of Beijing urban indoor :PM2.5, the highest value is 402 μg /m3. (The highest outdoor PM2.5 concentration was 5 50 μg /m3) (Journal of Environmental Health, October 2011), Safety, issue 3, 2012) From July to September 2011, the survey of seven cities along the Yangtze River showed the most serious excess xylene. The excess rate of toluene in Hangzhou and Nanjing was as high as 67%. The excess rate of formaldehyde in Nanjing and Chengdu is as high as 52% and 49%, respectively: Nanjing 40%, Hangzhou up to 38%, (Chinese Society for Environmental Sciences indoor environment and health branch and Landsee Group cooperation Anyang City decoration room (625) indoor air pollution survey: formaldehyde over standard rate of 72.80, The benzene over standard rate was 7.04%, toluene over standard rate was 13.28%, xylene over standard rate was 10.56 Han Wenxia < Preventive Medicine Forum > In 2011.5, 427 representative units of Guangdong indoor air sampling analysis of formaldehyde 0.15 mg/m3

Two, air is the biggest consumer goods!


A person can live up to 59 days on water alone; Only food without water, can live 5 days, the longest 17 days; No air, stop breathing, means death.    

A person needs 1 kg of food and 2 kg of water a day, but needs 10 kg of air. An adult breathes about 20,000 times a day, inhaling 15 to 20 cubic meters of air (30,000 to 400,000 kilograms of air in a lifetime!). Air is our must, we can't leave it!

★Air safety can not be ignored!


3. Air pollution damages human health

1. Air pollution is an important cause of cancer.
New cancer cases in China accounted for 26.9%(220 million)of the global total, and cancer deaths accounted for 26.9% (2.2 million) of the global total. The highest rates of disease and death. There is a direct link between these cancers and pollution in China. -- The World Cancer Report 2014 released by the World Health Organization 

2. When the concentration of pollutants in the atmosphere is very high, it will cause acute pollution poisoning or worsen the disease, even claiming thousands of lives in a few days;

3, even if the concentration of pollutants in the atmosphere is not high, but the human body for years to breathe this polluted air, will also cause: even if the concentration of pollutants in the atmosphere is not high, but the human body for years to breathe this polluted air, will also cause:
chronic bronchitis, bronchial asthma, emphysema, lung cancer and other diseases.

4, the health effects
of formaldehyde pollution for a long time inhalation of formaldehyde gas, can damage the liver, kidney, blood system, digestive system, respiratory system, central nervous system and immune system; Women and pregnant women exposed to low-concentration formaldehyde gas for a long time can lead to menstrual disorders, fetal abnormalities, reduced immunity of newborns, and decreased physique. Children and pregnant women are particularly sensitive to formaldehyde, causing memory and mental decline in adolescents. 2004 WHO announcement: Formaldehyde is identified as a carcinogen. Long-term exposure to formaldehyde, can cause chromosomal mutations, nasal cavity, oral cavity, nasopharynx, throat, skin and digestive tract cancer; The risk of tumor death from formaldehyde occupational exposure was more than twice that of the non-exposure group.
 
 
5. Health effects of PM2.5 pollution
WHO completed the 2012 Burden of Disease study. The results show that China has the heaviest PM2.5 pollution. China accounts for more than a third of global deaths caused by PM2.5. The global figure is 3.2 million, and China's estimate is 1.2 million.     
Studies have shown that people who are more sensitive to PM2.5 damage: children, the elderly, diabetics, people with cardiovascular disease, and people with chronic lung conditions. There is a strong positive correlation between the concentration of particulate matter in the atmosphere and the reporting rate of respiratory diseases and symptoms in children.    
For every 10μg/m3 increase in PM2.5 concentration, the reported rates of cough, sputum and bronchitis in children increased by 4.56%, 3.49% and 3.74%, respectively. (Journal of Environmental Health, June 2009, Vol. 26, No. 6) At present, the known effects of PM2.5(fine particulate matter) on human health mainly include: :
1)Increased mortality among patients with serious and chronic diseases;
2)Worsening of respiratory system and heart system diseases, increasing the number of such emergencies in hospitals;
3)Change lung function and structure;
4)The change of immune function increases the prevalence.
5)PAEs exists in most indoor environments in China. The detection rates of DBP and DEHP in indoor air and dust fall are 100%. The routes of PAEs entering the human body include inhalation, oral and skin contact. People, especially children, consume far more phthalates than previously thought, according to a study by German scientists. ★ It can cause allergic symptoms in children and increase asthma and bronchial obstruction. Wang Lixin BUILDING SCIENCE Vol. 26, No. 6 Jun.2010PAES can inhibit the synthesis and secretion of endocrine hormones and affect the occurrence and maturation of germ cells. And PAEs affecting embryo implantation and development are related to female reproductive system diseases and infant birth defects. Lin Xingtao, Wang Xiaoyi. "Progress in Research on the reproductive toxicity of phthalates in females" authoritative scientists and international research groups have determined that, The decline in sperm count and fertility in men over the past few decades has been linked to increased uptake of phthalates. Jiangsu People's Hospital: "The number of male sperm has dropped from 100 million/ml in the late 1980s to 20 million/ml today, and male fertility has greatly decreased."

Four, demand driven purification market, ushered in a great good.
1. The "two-child" policy increases the number of newborns, and children need better air and purification products.
2. The sudden emergence of "haze" has improved the public's awareness of purification, and the demand for "life safety" is second only to the "physiological demand"; Attention to health-related products has greatly increased, and health investment has increased. In 2012, the per capita health expenditure reached 2,057 yuan.
3. The government's investment in "haze control" drives social investment, and "haze economy" arises at the historic moment. In 2013, Beijing invested more than 8 billion yuan, driving social investment of more than 70 billion yuan. In 2014, the central government spent 10 billion yuan on environmental protection to control haze; 1.7 trillion yuan over the next five years; 10 trillion yuan over 10 years. In recent years, sales of air purification products have increased year by year, from 1.12 million units in 2011 to 5.76 million units (14.5 billion) in 2014, accounting for 69% of the total sales. It is estimated that in 5-10 years, it will increase by 48% every year; China's air purifier market has huge potential; The prospects look good.

5. Market dynamics and development direction


The former stage of air purifiers into explosive growth, but also brought many problems, product quality is uneven, the media often exposed including imported brands can not reach the publicity effect. Most products are fans and filters. It's the equivalent of wearing a big face mask. A lot of media reports are PM2.5. As a matter of fact, PM2.5 only accounts for a small part of the pollution. It is reported that there are hundreds or even thousands of common pollutants. PM2.5 refers to 2.5 microns of particulate matter, and bacteria, viruses and other microorganisms, such as the size of virus particles 0.01~0.05 microns, and automobile exhaust, industrial waste gas, home decoration produced formaldehyde and other harmful gases, their size is about 0.0005 microns. Equivalent to one fifth of PM2.5. This is far from being filtered by high efficiency filtration (micron scale). Not even activated carbon, which is about the same volume as oxygen. Actually solving this problem is quite difficult. As they say pollution is easier to clean up than it is to clean up, it is understandable why it took decades for foreign countries to do so. The best way is not to emit.
At present, the domestic and foreign purification market is still in the primary stage, the products are mainly stand-alone, other forms of products are few, did not form the mainstream position; The technology is single, homogeneity is serious, and filtering is the mainstream technology. The effect only highlights one source of pollution (particulate matter such as PM10 and PM2.5); Even filtering has to solve the main contradiction; The current air purifier is used indoors, and the indoor particulate matter below PM0.3 is absolutely dominant (test data show that the number of PM0.3 is more than two hundred thousand units; PM2.5 is only a few hundred units. In the indoor more and more tiny particles and more difficult to cure the microorganisms, bacteria, viruses and toxic and harmful gases to the human body harm; Filtering technology is weak and requires the combination and innovation of multiple technologies to achieve the best results. In today's world, the spread of the Ebola virus has not been effectively controlled, and the "incidents" caused by toxic and harmful gases continue to occur. We need to accelerate technological progress.

Hongda will continue to take advantage of ultraviolet technology and combine various new technologies. Give play to the advantages of various technologies and strive to achieve purification effect.
