The World Health Organization(WHO) believes that 29% of lung cancer, 24% of stroke, 25% of heart disease and 43% of lung disease deaths are due to air pollution. 92% of the world’s population cannot breathe safe air, and 7 million people die directly or indirectly from air pollution each year.

Long-term inhalation of polluted air will further damage our metabolism, resulting in obesity, diabetes and high blood pressure. Pregnant women breathing polluted air may cause premature birth or miscarriage, or give birth to children with hyperactivity and autism. Air pollution also often causes asthma, allergic rhinitis, bronchitis, pneumonia, and may even lead to skin allergies, arteriosclerosis, myocardial infarction, stroke, dementia, as well as cancers such as lung cancer, breast cancer, and liver cancer. People who care about the health of themselves and their relatives and friends should know the air pollution exposure data of their environment at anytime and anywhere. Data tells the truth. The essence of air pollution detection is preventive medicine.
