Tea is one of the most frequently consumed drinks due to its favourite taste and the health benefit. Tea is produced by several processes and drying is very important step to develop the flavour and destroys the enzymes in tea. However, during drying tea, polycyclic aromatic hydrocarbons some of which are carcinogen and genotoxin are naturally produced. The risk of PAHs by drinking tea was characterized by determining contents of 4 PAHs in tea. 4 PAHs including Benz(a)anthracene (BaA), Chrysene (CHR), Benzo(b)fluoranthene (BbF) and Benzo(a)pyrene (BaP) were investigated by GC-MS in total 468 tea products, which were contaminated up to $4.63ng\;g^{-1}$. Mate tea was the most highly contaminated by BaA, CHR, BbF and BaP and followed by Solomon's seal and Chrysanthemum. The Margin of Exposures calculated by the concentration of BaA, CHR, BbF and BaP and consumption amount of tea were higher than 10,000, and the risk of PAHs in tea were low concern to public health.

본 연구는 서울에서 유통되는 식품용 융합 환제에 대하여 위해물질인 벤조피렌 등의 PAHs (polycyclic aromatic hydrocarbons) 오염실태를 조사하고 위해도를 평가하였다. 2010~2013년 서울약령시 한약재 판매업소 등에서 31종 93건의 환제를 수집한 후 시료를 추출, 여과, 농축하여 SPE (Sep-pak florisil)로 유출시킨 후 다시 농축하여 액체크로마토그래프로 분석하였다. 분석한 결과 총 8종 PAHs 평균 함량은 $10{\mu}g/kg$ 이하이었고, PAHs 위해성 평가 결과 초과발암위해도는 일상 생활에서의 노출에 의한 것보다 낮았고, 노출안전역(MOEs)은 대부분의 시료가 위해를 무시할 만한 수준으로 안전한 것으로 평가되었다. 향후 의약용 환제와 식품용 환제의 위해물질에 대한 비교 융합연구가 필요하다.

Background: The Korea Centers for Disease Control and Prevention (KCDC) has identified cases of people suspected of suffering lung disease potentially caused by chloromethylisothiazolinone/methylisothiazolinone (CMIT/MIT) used in humidifier disinfectants (HDs). The Korean Ministry of Environment (MoE) epidemiological investigation and toxicity test study found that HDs caused health damage such as asthma and lung disease. Objectives: The main purposes of this study were to classify the HD exposure rating and to analyze the exposure characteristics that affect exposure to CMIT/MIT HDs. Methods: The exposure characteristics and socio-demographic characteristics of victim participants using CMIT/MIT HDs were investigated through questionnaires. An inhalation no observed adverse effect level (NOAEL) for CMIT/MIT was produced based on inhalation toxicity values. Exposure ratings (class 1~class 2) were cross-tabulated with clinical ratings (acceptable~unacceptable). A correlation analysis was conducted with the main exposure characteristics that affect the exposure concentration of CMIT/MIT HDs. Results: The concentration in indoor air of CMIT/MIT was 8.75±25.40 ㎍/m³, and the exposure concentration was 2.30±6.29 ㎍/m³. The CMIT/MIT exposure rating of 67 participants with high exposures of not more than MOE 100 were evaluated as 14.5%, while the damage participants who matched the clinical rating made up 4.5%. The exposure concentration of CMIT/MIT showed a positive correlation with the daily usage amount and usage frequency, and a negative correlation with volume of the indoor environment. Conclusions: A new exposure rating could be suggested and calculated based on the MOE, and the factors affecting the exposure concentration could be identified.

식용유지류의 섭취로 인해 발생하는 PAHs의 대표적인 발암물질인 벤조피렌의 안전성을 판단하기 위해 시중에 유통되는 288건의 식용유지제품에 함유된 벤조피렌 함량을 분석한 후 위해성을 평가하였다. 사용된 제품은 옥수수기름, 포도씨유, 올리브유, 들기름, 미강유, 참기름, 콩기름, 해바라기유 등이며 벤조피렌의 검출 범위는 불검출 ${\sim}4.78{\mu}g/kg$이었고 평균 농도는 $0.11{\mu}g/kg$로 나타났다. 국민건강영양조사 5기 2차년도(2011) 자료를 이용하여 전체인구집단과 섭취군의 식용유지류 섭취량을 산출하여 만성 1일 인체노출량을 평가한 결과 식용유지류 섭취로 인한 벤조피렌 노출량은 전체인구집단의 경우 $4.26{\times}10^{-3}ng/kg$ b.w./day, 식용유지류 섭취군의 경우 $7.64{\times}10^{-3}ng/kg$ b.w./day로 나타났다. 인체 위해정도를 파악하기 위해 벤조피렌의 mouse 위상부암에 대한 $BMDL_{10}$값인 0.31~0.74 mg/kg b.w./day와 만성 1일 인체노출량을 이용하여 산출한 MOE 값은 전체인구집단에서는 $7.28{\times}10^7{\sim}1.74{\times}10^8$, 섭취자군에서는 $3.95{\times}10^7{\sim}9.42{\times}10^7$ 수준이었다. 따라서 식용유지류 섭취로 인한 벤조피렌 인체노출의 위해정도는 매우 낮은 것으로 판단된다.
