초록

Polycyclic aromatic hydrocarbons(PAHs)의 인체에 대한 위해성 정도를 판단하기 위해 PAHs의 대표독성물질인 benzo(a)pyrene의 독성을 기준으로 하는 TEFs를 적용하여, PAHs의 주요노출식품에 의한 위해성 평가를 수행하였다. 숯불구이쇠고기, 숯불구이돼지고기, 숯불구이닭고기, 햄, 베이컨, 및 식용유지 등을 대상으로 PAHs 오염도를 모니터링 한 결과 숯불구이닭고기에서 총 PAMs농도가 9.3ppb로 가장 높게 검출되었으며 각각의 congener들 모두 다른 식품에서 보다 높게 나타났다. 반면에 숯불구이쇠고기, 베이컨, 숯불구이돼지고기, 햄 및 식용유지의 총 PAHs는 각각 0.2ppb, 0.3ppb, 0.7ppb, 0.8ppb 및 1.2ppb로 비교적 낮은 값을 나타냈다. TEFs값을 적용하여 환산된 오염도 값의 경우에서도 숯불구이닭고기가 가장 높은 값을 보였고, congener들의 농도를 비교했을 때 숯불구이닭고기, 숯불구이돼지고기, 베이컨, 숯불구이쇠고기 및 햄에서 모두 BaP의 농도가 각각 1.88 $\mu\textrm{g}$-TEQ$_{BaP}$/kg, 0.19 $\mu\textrm{g}$-TEQ$_{BaP}$/kg, 0.08 $\mu\textrm{g}$-TEQ$_{BaP}$/kg, 0.04 $\mu\textrm{g}$-TEQ$_{BaP}$/kg 및 0.02 $\mu\textrm{g}$-TEQ$_{BaP}$/kg로 congener들 중 가장 높게 나타났고 식용유지에서는 dibenzo(a,h)anthracene의 농도가 0.21 $\mu\textrm{g}$-TEQ$_{BaP}$/kg으로 가장 높은 값을 나타냈다. 우리나라 사람들의 PHAs 주요노출식품 섭취로 인한 만성1일 인체 노출량은 4.32${\times}$$10^{-4}$ $\mu\textrm{g}$/kg/day으로 산출되었으며 선정된 식품 중에서 숯불구이 닭고기의 노출기여도가 가장 높았다. PAMs의 초과발암 위해도는 만성1일 인체노출량과 BaP의 발암력인 7.3 (mg/kg/day)$^{-1}$을 고려하였을 때 3.44${\times}$$10^{-6}$ , 백만명당 3∼4명 수준이었다. 우리나라 대표식단을 통한 PAMs 노출량을 반영할 수 있는 위해성 평가가 추후 계속되어야 할 것으로 사료된다. 할 것으로 사료된다.

This study was executed to determine the cumulative dietary risk of PAHs exposed by food ingestion. Food samples including barbecued beef, barbecued pork, grilled chicken, ham, bacon and vegetable oil which were collected from food markets. These samples were saponified, extracted and cleaned up to purify PAHs, and then the purified sample solutions were analyzed by HPLC-FL. Generally, the levels of total PAHs in barbecued beef (0.2 ppb), bacon (0.3 ppb), barbecued pork (0.7 ppb), ham (0.8 ppb), and vegetable oil (1.2 ppb) were low, whereas the level of total PAHs in grilled chicken (9.3 ppb) was significantly high. For the exposure assessment of PAHs due to food ingestion, PAHs levels converted into TEQ$_{BaP}$, the average body weight for 20-73 age group and consumed levels of food proposed from report on the National Health and Nutrition Survey were used. The estimated lifetime average daily intake of dietary PAHs was 4.32${\times}$10$^{-4}$ $\mu\textrm{g}$-TEQ$_{BaP}$kg/day as the mean value. The dietary risk adjusted to cancer potency of benzo(a)pyrene as 7.3 (mg/kg/day)$^{-1}$ was 3.44${\times}$10$^{-6}$ based on current data.ata.
