Korean Karaoke Machines A Hit In Japan The Dong-a Ilbo

Formaldehyde was analyzed utilizing a most cancers efficiency of 4.6×10-2 (mg/kg/day)-1 in a linearized multistage model based on dose-response data from Kerns et al. (1983). The most cancers efficiency of benzene (WHO, 2000) was 3.6×10-2 (mg/kg/day)-1 (Table 4). Samples of 5 VOCs have been collected by private air sampler (Sibata, Japan) with a Tenax sorbent tube (1/4′′×20 cm chrome steel, Supelco, USA). Samples have been collected over a interval of 30 minutes and sampler flow was zero.2 L/minute. After the pattern was collected, the sorbent tube was put into Swagelok, sealed with Teflon caps on each ends and refrigerated at lower than -75°C until evaluation. VOCs were measured within a week of sampling, using GC/MSD (gas chromatography/mass selected detector, USA) connected to a thermal desorber inside.

Workers risks were calculated based on the inhalation rate of a chronic publicity by way of single route, 20m3/day (90th higher confidence restrict value) by the precautionary principle (US EPA, 1997). Individuals use various indoor areas or public amenities for his 강남 셔츠 or her lifetime and inhalation of polluted indoor air will increase human well being risks (Gioda and Aquino Neto, 2003).

In movie theaters, the danger to staff and frequent customers was 1.20×10-4 and 9.34×10-6, respectively. The danger of HCHO publicity for users in movie theaters reported by Weng et al.
