Investigation and Analysis on Residents'Cognition Status of Formaldehyde and Carbon Dioxide in Hubei Region
In recent years,with the development of the economy,indoor air quality has become one of the impor-tant factors that threaten people's health.Among them,formaldehyde and carbon dioxide are widespread to pollute the air and seriously endanger people's health,and it is imperative to further implement the absorption and purifi-cation of such gases.Using a questionnaire survey,the current situation of residents'awareness of the formalde-hyde and carbon dioxide hazards and their willingness to purchase related purification device in Hubei Province was randomly investigated.Furthermore,zing regression analysis,the statistical method was used to analyze the correlation between the formaldehyde hazard awareness and willingness to purchase air purification equipment.The results showed that Hubei residents generally had insufficient understanding of formaldehyde and carbon di-oxide hazards.There were also significant differences in hazard awareness among different characteristics of the population.However,after understanding the hazards,the vast majority of residents were willing to install such purification at home,provided that their economic conditions permit.At the same time,it is necessary to promote the popularization of formaldehyde and carbon dioxide purification devices.
