Hazards of Particulate Pollutants
The hazards caused by particulate pollutants are manifested in the following 2 levels.
(1) the harm to people’s physical and mental health: particle pollutants particle size is small, with a large specific surface and its not smooth surface, very easy to absorb other harmful substances in the air such as germs, viral infections, heavy metals and VOC, with such harmful substances of the particles into the human body according to the lg puricare wearable air purifier system, endangering the human body cells and various human organs, will lead to great damage to the human body. It is found that prolonged exposure to PM2.5 pollution environment causes greater damage to the human respiratory tract and cardiovascular system. The total number of blood cells in the blood night and its coagulation function cross-section in the long-term exposure to PM2.5 pollution environment will lead to cardiovascular and cerebrovascular diseases and other diseases. The long-term exposure to PM10 pollution environment will cause the elderly to have reduced heart and lung function and be prone to diffuse obstructive emphysema and lung disease.
PM2.5 is more harmful to the elderly and small children, and the total number of respiratory medicine hospital outpatient clinics in pediatric hospitals exceeds other time frames during the fall and winter months when particulate pollutants are more pronounced. Especially during the heating period in the north, the number of patients stowed in the hospital outpatient respiratory medicine department is significantly higher. Long-term daily life or work in the natural environment of high-quality particulate pollutants is prone to cause myocardial infarction in humans, and the danger to the old population is more significant.
(2) the harm to people’s daily life and their production and manufacturing movement: particle pollutants because of small quality, easy to float in the air, particle pollutant composition is very complicated, phosphate and its potassium thiocyanate type of particle pollutants to the light source with transmittance effect, carbon content class of particle pollutants, especially black oil particles can digest and absorb visible light, enhance the extinction rate of the light source and thus can reduce the visibility of the air, on This can cause great harm to our traffic and daily life and work.
Pollutant Hazards
Indoor formaldehyde, volatile phenols as the main VOC is the key components of indoor air pollution, the harm to us as follows.
(1) the harm of fragrance vapor pollutants: pre-touch benzene compounds, dental and respiratory system mucous membranes can produce similar to sepsis of urinary and mental debilitating conditions, long-term exposure to volatile phenols can increase the morbidity and mortality of blood diseases. The metabolism of benzene in the spinal cord causes toxic substances to the blood at night, and the spinal cord is the body’s hematopoietic body, and toxic metabolites have a greater destructive effect on the hematopoietic body; long-term exposure to xylene can lead to a decline in memory, concentration and fitness work; higher concentrations of xylene have a greater impact on the human body. High concentrations of xylene can cause dizziness, nausea, vomiting, poor appetite and lower abdominal pain.
It has been found that long-term exposure to benzene and butadiene pollution increases the risk of low-grade malignancies. For special families such as pregnant mothers, volatile phenols are more harmful to women and babies during pregnancy and can cause congenital defects in fetal babies.
(2) the hazards of indoor formaldehyde: formaldehyde is harmful to our specific performance in three levels, in the higher concentration of the natural environment can cause significant stimulation effect on the human respiratory system and produce swelling, eye stinging, headaches and other diseases; skin direct contact with indoor formaldehyde vapor, can lead to skin allergies, pigmentation spots, atrophy and other diseases, and the human body if often in the conditions of lower concentrations of indoor formaldehyde, will gradually cause chronic poisoning.
