It was found that perfluorooctanesulfonate（PFOS） and perfluorooctanoate（PFOA） were the most prominent PFCs, with average concentrations of 5.73 mg/L and 5.46 mg/L for textile workers, and 2.55 mg/L and 2.84 mg/L for barbers.PFOS and perfluorohexanesulfonate（PFHxS） concentrations revealed a positive correlation in blood samples（p 〈 0.01）, and concentrations among PFOS, perfluorononanoic acid（PFNA） and perfluorodecanoic acid（PFDA） also revealed positive correlations（p 〈 0.01）. The influence of gender and age on PFC concentration in blood was also investigated, and the results showed that there was no statistically significant difference between the male and female samples, as well as in samples from people with different ages. Generally speaking, the textile workers展开更多

Methods: 53 barbershops in Shenzhen were selected bysampling, and their 382 female barbers were given abase-line survey and assessment of intervention followingthe intervention. Results: The survey showed that female barbersgenerally have little education and knew little aboutSTDs/AIDS. They also had some misunderstanding aboutSTDs/AIDS. Most of them knew the main transmission ofSTDs/AIDS' through sexual contact, but didn't knowwhether AIDS could be transmitted through casual contactin daily life. Their knowledge of STDs/AIDS was limited,but they had lower condom use rates and correct ideasabout when to see the doctor. Conclusion: Health education and behavioralintervention related to STD/AIDS on special populationwere effective and or good social consequence.展开更多
