â—Ž Carbon dioxide: less than 0.1%. Carbon dioxide is a comprehensive indirect indicator of indoor air quality. If the concentration of carbon dioxide increases, children will feel nauseous and headaches.
Carbon monoxide: less than 5 mg/m3. Carbon monoxide is the most common toxic gas in indoor air and it can easily damage children's nerve cells, which is extremely harmful to children's growth.
â—Ž Bacteria: The total number is less than 10/m3. Children are in the stage of growth and development, and their immunity is relatively low. We must do a good job of sterilizing and disinfecting the room.
â—Ž Indoor air temperature: children's body temperature regulation ability is poor, summer should be controlled at 28 degrees Celsius, indoor temperature in winter should be above 18 degrees Celsius. However, attention should be paid to the influence of air-conditioning on children's bodies and their rational use.
â—Ž relative humidity: should be guaranteed between 40% -65%. If the humidity is too low, children's respiratory tract may be easily damaged. If the humidity is too high, evaporation of sweat may be unfavorable.
â—Ž Air flow: Under the premise of ensuring ventilation, the air flow should not exceed 0.3m/s; if it is too large, it will make children feel cold;
â—Ž lighting lighting: children in the writing, the room light to be evenly distributed, no strong glare, desktop illumination should not be less than 100lx;
â—Ž Noise: Children's room noise should be controlled below 50 decibels. Noise has a great impact on children's brain activity. On the one hand, it distracts children from their attention in learning activities. On the other hand, prolonged exposure to noise can cause children's psychological stress and affect their physical and mental health.

1. Formaldehyde pollution damage to the baby:
Experts believe that excessive formaldehyde may have more serious effects on children's hematopoietic organs than adults. Children have hematological characteristics different from adults, their hematopoietic function is unstable, hematopoietic reserve is poor, hematopoietic organs are easily infected, and hematopoietic organs are prone to nutritional deficiencies. At the same time, formaldehyde has become a major cause of childhood asthma.
2. Lead damage caused by lead pollution:
The lead particles in the air are mainly suspended in the atmosphere about 1 metre away from the ground. The lead concentration is 16 times that of the ground 1.5 meters away. The children's breathing zone is just in this position, and the absorption rate of lead in children's respiratory tract is 1.6-2.7 times that of adults. Children's gastrointestinal digestive ability is stronger than that of adults. Kidney excretory function is only 60% of that of adults. Coupled with children's mouth and hand movements, they are easily touched and swallow lead-containing particles, so children are more prone to lead poisoning than adults.
According to international standards, blood lead concentrations in excess of 10 ug/dl (micrograms per deciliter) are lead poisoning. The blood lead concentration does not produce obvious clinical symptoms when it is around 10 μg/dl, but it has an impact on children's growth and development, and damages the major systems such as nerves, digestion, cardiovascular, urinary system and immune system. Children with mild lead poisoning have blood lead concentrations between 10-20ug/dl, 20-45ug/dl as moderate, 45-70ug/dl as severe, and more than 70ug/dl as extremely severe lead poisoning. Lead poisoning destroys children's neurological development and affects intelligence. Children's general lead poisoning may be unresponsive, inattention, hyperactivity, simulated learning difficulties, movement disorders, impulsivity, aggressive behavior, recurrent respiratory infections, and poor physical development. The hazards of lead poisoning are occult, persistent, and multi-systemic.
Love Tips:
â—Ž General lead poisoning can promote the elimination of lead through food. For example, drink milk, eat more soy products, seafood, fresh fruits and vegetables, etc. to supplement calcium, iron, zinc and vitamins. Because calcium and vitamins can reduce neurotoxicity, and lead and zinc are resistant, zinc supplementation helps reduce lead intake.
â—Ž In addition to minimize the baby's stay on the road.
â—Ž Let your baby wash your hands before meals and develop good hygiene habits. Parents should pay attention to separate washing of baby clothes if they are frequently exposed to lead-containing substances.
