초록

전국 25개 지역 염전에서 생산된 갯벌천일염 뿐만 아니라 천일염을 결정하는 함수 및 근원이 되는 염전 저수지 해수를 채취하여 가소제 오염수준을 평가하고, 갯벌천일염 및 염전 결정지 PVC 사용연수에 따른 환경호르몬의 상관관계를 분석하였다. 천일염의 DEP는 불검출에서 1.55 ppb 수준을 나타내었으며, DIBP는 불검출에서 2.38 ppb, DBP는 불검출에서 4.90 ppb, DEHA는 불검출에서 2.32 ppb 수준으로 검출되었으며, BBP는 불검출에서 1.45 ppb 수준으로 무시할 정도의 수준이었다. 천일염을 생산하는 염전에서 결정지 바닥재로 PVC 장판을 사용하면서 최근 가장 문제가 되고 있는 DEHP는 천일염을 생산하는 지역에 따라 불검출에서 268.5 ppb 수준으로 검출되었으며, 이러한 결과는 천일염에 0.268 ppm 포함되어 있는 것으로, 인체 안전성을 우려할만한 수준은 아닌 것으로 나타났다. 또한 DMP, DPrP, DNPP, DNHP, DCHP는 모든 시료에서 불검출 되었다. 전국 염전 저수지 해수 및 함수에 포함된 프탈레이트는 무시할 정도의 수준이었으며, 염전 저수지 해수에 대한 DEHP는 불검출에서 3.4 ppb 수준, 함수는 불검출에서 21.4 ppb 수준을 나타내어 불검출 수준이었다. 또한 염전 결정지 PVC 장판 사용기간에 따른 환경호르몬(DEHP) 오염여부가 의심됨에 따라 장판 사용 년수와 천일염에서 검출된 DEHP와의 관계를 분석한 결과 r=0.0362의 낮은 상관계수를 나타내었다.

The purpose of this study was to evaluate plasticizer pollution levels in mudflat solar salt, salt water and sea water of the nationwide saltpan. Also, it was analyzed the relationship between DEHP in solar salt and PVC mat following private period. DEP (ranging from 0.00 to 1.55 ppb), DIBP (0.00~2.38), DBP (0.00~4.90), DEHA (0.00~2.32), and BBP (0.00~1.45) in solar salt were shown a extremely low concentrations, and DEHP was present a concentrations ranging from 0.00 to 268.5 ppb in solar salt. Further, DMP, DPrP, DNPP, DNHP, and DCHP were not detected in all solar salt. Phthalate in sea water and salt water was present a infinitesimal amount levels. DEHP levels in sea water and salt water were not shown a high risk levels ranging from 0.00 to 3.4 ppb, and from 0.00 to 21.4 ppb, respectively. As expected in PVC mat of nationwide saltpan, the correlation between DEHP in solar salt and PVC mat private period showed a low positive correlation coefficient ($r^2$=0.0362).
