Sodium sulfide plant in Zaozhuang City,[link widoczny dla zalogowanych], a young environmental pollution on the health effects of survey
Factors that determine the health of critical control points and control methods before and after HACCP implementation and comparison of the health indexes. [Results] The use of HACCP, the five-star hotel the total number of bacteria in indoor air can be inhaled particulate matter,[link widoczny dla zalogowanych], formaldehyde,[link widoczny dla zalogowanych], carbon dioxide, the pass rate, public supplies tea, towels, bed and bedding, wash tank, toilet seat, slippers,[link widoczny dla zalogowanych], and the pass rate customers with cosmetics and sanitary quality of the legal identity within the pass rates were significantly increased (P <O.O1).

Hotel industry to explore new ways of supervision and management of Health, 2002, HACCP applied to five-star hotel in Jining City, health supervision, and achieved significant results. 1 1.1 objects and methods the object selected in 2002 a representative of the days of Jining City, Germany Hotel, Holy Land Hotel, Hong Kong Mansion, Bai, restaurants, hotels 5 star hotels benefit for the study. l_2 method in April 2002 hotel rooms in five air samples collected within the total number of bacteria detected with inhalable particulate matter, formaldehyde, carbon dioxide, collecting public tea, towels, bed and bedding, wash tank, toilet seat, slippers, the total number of bacteria detected , coliform bacteria, pathogens, according to GB/T17220-1998 {health monitoring in public places According to test results, analysis of 5 hotels hazards exist to determine the sanitary quality control point, to propose and implement appropriate improvement measures. September 2002 once again the five hotels in the indoor air, public goods, the customer for testing cosmetics on the 2 test results for statistical analysis to test the effect of the use of HACCP. 1.3 determine the standard according to GB9663-1996, 3 ~ 5 star hotel standards for indoor air quality standards is the health of carbon dioxide �� 0.07, formaldehyde �� O. 12mg / m. , Inhalable particulate matter �� 0.15mg / m. Total number of bacteria �� 1O a / dish; 1 to 2 star hotels indoor air quality health standards for carbon dioxide passing �� 0.10oA, formaldehyde �� 0.12mg / m. , Inhalable particulate matter �� 0.15mg / m. Total number of bacteria �� 10 pieces / plate. Public Goods Health tea quality acceptance criteria are the total number of bacteria <5du/ml, not detected coliform and pathogens; towels and bedclothes in total bacterial count <200cfu/25cm, not detected coliform and pathogens; washing pool , toilet seat, no pathogens were detected slippers. Customer quality standards with the cosmetic standard of health within the total number of bacteria �� 1000 �� / g, mercury limit of 1g / g, arsenic limit is 10g / g, lead limit is 4Og / g, alcohol limit is 0.2, no pathogens were detected ; legal identity cases, 3 cases of auricular, preauricular congenital fistula in 3 cases, the other 4 cases; 195 cases of nasal disease in 64 patients with chronic sinusitis, chronic rhinitis 63 cases, 37 cases of nasal septum deviation, chronic allergic rhinitis 15 cases, chronic allergic sinusitis 1O cases, 6 cases of atrophic rhinitis; 104 cases of throat disease, 89 cases of chronic tonsillitis, chronic pharyngitis in 7 cases, 4 cases of tonsillar hypertrophy, 4 cases of chronic laryngitis. 3 to discuss the test results, as sodium sulfide plant in Zaozhuang City, a discharge of harmful gases and particulates and other reasons, the campus is located in polluted air in the S0, NO2, CO, IP non-contaminated areas the concentration of 1.16 ~ 18.38 times These substances can be around people, especially young people's health hazards.
