Formaldehyde is serious stimulant in human body to colorless machine that stimulative smell becomes. International Agency for Research on Cancer IARC confirmed that formaldehyde is carcinogenicity as result that do biological test. But, it is not proved that formaldehyde is carcinogenicity in a dynamics investigation result person. When formaldehyde reacts with hydrochloric acid and creates carcinogenic substance that is bis-chloromethyl ether(BMCE), United States of America industry safety health researcher is advising to manage formaldehyde by profession anger carcinogenic substance. And the our country Ministry of Labor also designated formaldehyde by carcinogenic substance.
Formaldehyde been assuming from treatise to carcinogenic substance after stream in of pile up for about development of diffusive sampler and application speak try to. Though various kinds are to formaldehyde measurement method we among them, use Solids sampler and diffusive sampler, and SKC’s diffusive sampler and experimented comparison. Experiment place did to an interior experiment and billiard hall, Interior workshop, and a dissection pathology laboratory that use Chamber.
Result of an experiment is same as following ;
1. Formaldehyde desorption efficiency of diffusive sampler was detected by 78%-84.5%
2. Sampler rate of diffusive sampler that base formaldehyde sampling and SKC’s diffusive sampler in chamber interior appeared from sampling 63.95 ml/min to 69.31 ml/min 240 minutes in 120 minutes, and decide 66.64 ml/min that is average value of two by standard SR and substituted in an external experiment.
3. Numerical value of diffusive sampler showed high interior workshop which is with billard hall when saw total average, and numerical value of solids sampler showed high in a dissection pathology laboratory.
