Investigation And Analysis On The Sanitary Condition Of Accommodation,Bathing And Swimming Places In Urban Areas Of Jilin Province From 2014 To 2017

Objective:Investigate the health status of accommodation,bathing and swimming pools in urban areas of Jilin province from 2014 to 2017,and analyze the changing trend of sanitary status of accommodation,bathing and swimming pools in different years,different grades and different economic levels in Jilin Province,in order to provide scientific evidence for improving sanitary status of public places in Jilin Province.Methods:By multi stage sampling,from 2014 to 2017,accommodation,bathing and swimming in 9 cities of Jilin province were randomly selected,each of them 6,and a total of 648 public places were used as monitoring points to carry out health monitoring in public places.The hygiene monitoring items for accommodation and bathing places include indoor air quality testing and public appliances hygiene inspection.The contents of air quality testing include the number of bacteria in the air,formaldehyde,CO,CO₂ and PM10,and the contents of public goods and appliances include the total number of bacteria,the number of coliform bacteria and the pathogenic bacteria?the total number of fungi?.The hygienic monitoring items of swimming places include:pH value,turbidity,urea level,free residual chlorine,total bacteria count and coliform number of swimming pool water.Excel 2013 was used for data sorting,and SPSS 24 software was used for statistical analysis.Results:1.The qualified rates of total number of bacteria,formaldehyde,CO,CO₂ and PM10 in the air of urban accommodation in Jilin province from 2014 to 2017 were72.2%,99.3%,90.7%,93.7%and 99.5%.The total qualified rate of the public goods and appliances in the accommodation was 95.5%.The total number of bacteria in the tea set,the number of coliform,the total number of towels,the number of coliform,the total number of bacteria in the slippers,the total number of bacteria in the bedding,and the number of coliform bacteria for bedding were 94.3%,100%,98.1%,100%,79.6%,96.9%and 99.7%,respectively.2.There was a significant difference in the total number of bacteria,formaldehyde and PM10 in the air of accommodation places in different years,with statistical significance?P<0.05?.Among them,the pass rate of total bacteria is increasing year by year,and the pass rate of formaldehyde is decreasing year by year.There was a significant difference in the level of formaldehyde in different grades of accommodation,with statistical significance?P<0.05?.The qualified rate of formaldehyde in the above three-star accommodation is 100%higher than that in the three places below 98.5%.There was no significant difference in the total number of bacteria,CO,CO₂ and PM₁₀ among different grades of accommodation.The qualified rate of the total number of urban air bacteria with a per capita GDP of$10 thousand is higher than that of the city with a per capita GDP of more than 10 thousand dollars,and the rate of qualification of formaldehyde,CO and CO₂ in urban air with a per capita GDP more than 10 thousand dollars is higher than that of the city with a per capita GDP<10 thousand dollars?P<0.05?.3.There was significant difference in the qualified rate of the total number of bacteria and the total number of bacteria in the public articles and utensils in different years of accommodation,which was statistically significant?P<0.05?,and the percentage of the total number of bacteria in the towel showed an increasing trend year by year?P<0.05?.There was no significant difference in the total number of bacteria,the number of coliform,the total number of bacteria in the towel,the number of coliform,the number of bacteria in the bedclothes,the number of coliform bacteria in bedding,and the percentage of the bacteria?P>0.05?.There were no statistical differences between the total number of bacteria and the number of coliform bacteria and the pathogenic bacteria of the tea sets,towels and bedding in different economic levels?P>0.05?.4.From 2014 to 2017,the qualified rates of CO and CO₂ were 79%and 66.1%respectively in the air bath area of Jilin.The qualified rate of public goods and appliances was 88.5%.The total number of bacteria,the number of coliform,the total number of bacteria in the towel,the number of coliform and the pathogenic bacteria of the towels were 95.7%,100%,98.3%,100%and 48.8%,respectively.5.There were significant differences in the qualified rates of CO and CO₂ in different years of bathing air,with statistical significance?P<0.05?,and the qualified rate of CO and CO₂ all showed an upward trend.The levels of CO and CO₂ in different bathing places were significantly different?P<0.05?.The eligible rates of CO and CO₂ in bathing places without accommodation were lower than those in bathing places with accommodation.The qualified rate of urban CO with a per capita GDP value of more than 10 thousand dollars is higher than that of a city with a per capita GDP less than 10 thousand dollars;the per capita GDP value of the city CO₂ of more than 10 thousand US dollars is lower than the city with a per capita GDP less than 10 thousand dollars.6.There were significant differences in the qualified rate of the total number of bacteria in the public articles and utensils in different years of bath,which was statistically significant?P<0.05?,and the percentage of qualified bacteria in the tea set showed a declining trend.There was no significant difference in the total number of bacteria,coliform bacteria and the pathogenic bacteria?total fungi?of the tea and towels in different bathing places?P>0.05?.The qualified rate of urban slippers with GDP per capita of$10 thousand per capita is lower than that of the city with GDP less than 10 thousand dollars per capita;There was no statistical significance in the total number of bacteria in the tea set,the number of coliform in tea set,the qualified rate of the total number of towels and the number of coliform bacteria,and the cities with the per capita GDP of more than 10 thousand dollars and the per capita GDP less than$10 thousand in the city's bathing place?P>0.05?.7.From 2014 to 2017,the turbidity,pH,urea,coliform,bacterial count and free residual chlorine of swimming pool in the swimming pool of Jilin province were99.7%,98.9%,97.4%,95.8%,87%and 42%,respectively.8.The difference of pH qualification rate in swimming pool water in different years was significant?P<0.05?,and there was no statistical difference between turbidity,urea,free residual chlorine,total bacterial count and coliform group in swimming pool water?P>0.05?.There was no significant difference in turbidity,pH,urea,coliform,bacterial count and free residual chlorine?P>0.05?in swimming pool water of different swimming pools.The qualified rate of pH and urea in cities with a per capita GDP value of more than 10 thousand dollars is lower than that of the city with GDP less than 10 thousand dollars per capita.The qualified rate of isolated residual chlorine and bacteria in urban middle reaches of 10 thousand dollars per capita is higher than that of the city with GDP less than 10 thousand dollars per capita.Conclusions:1.From 2014 to 2017,the qualified rate of bacteria in the air of residential areas in Jilin increased,and the qualified rate of formaldehyde showed a downward trend.The qualified rate of formaldehyde in the three-star and above accommodation is higher than that in the places below three stars.The qualified rates of total bacteria and coliform bacteria in public places were higher and showed an upward trend year by year.The qualified rate of formaldehyde,CO and CO₂ in urban air with per capita GDP value of more than 10 thousand dollars is higher than that of cities with per capita GDP less than 10 thousand.2.From 2014 to 2017,the qualified rates of CO and CO₂ in the air of the bathing places in Jilin province were all low,but they were increasing year by year,and the percentage of the total number of bacteria in the bathing places showed a trend of decreasing year by year.The qualified rate of urban slippers pathogens?fungi total?per capita GDP is more than 10 thousand dollars,which is lower than that of cities with GDP per capita of less than 10 thousand dollars.3.From 2014 to 2017,the qualified rate of free residual chlorine in swimming pools of swimming pools in Jilin was low,and half of the swimming places were not qualified.The qualified rate of pH and urea in cities with a per capita GDP value of more than 10 thousand dollars is lower than that of the city with GDP less than 10thousand dollars per capita.The qualified rate of isolated residual chlorine and bacteria in urban middle reaches of 10 thousand US dollars per capita is higher than that of the city with GDP less than 10 thousand dollars per capita.
