摘要

環境荷爾蒙之中的類雌性素(xenoestrogen)，具有模仿天然激素之功用，許多研究顯示，類雌性素能使多種水生生物和野生生物體，其體內的生殖內分泌系統產生異常。Vitelfogenin（卵黃前質　素或稱　卵黃前質蛋白：VTG）為常用於監測類雌性素的生物指標。為了瞭解福壽螺(Pomacea canaliculata)是否適合應用於監測環境中類雌性素，本研究初步於2009年9月及2010年2月分別於臺南、彰化、苗栗、宜蘭及屏東共五個地區的水稻田進行福壽之採集，並檢測其體內VTG含量。實驗結果顯示，福壽螺VTG含量9月份以苗栗地區(0.92±0.43μg/ml)最高，其次為彰化地區(0.55±0.40μg/ml)，最低為臺南(0.28±0.21μg/ml)及宜蘭(0.48±0.22μg/ml)地區；2月份以彰化(0.77±0.20μg/ml)及屏東(0.71±0.18μg/ml)地區略高，臺南(0.36±0.08μg/ml)、宜蘭(0.51±0.10μg/ml)與苗栗(0.45±0.11μg/ml)此三樣點與對照組並無顯著差異。結果顯示，部份野外的福壽螺其體內VTG含量相對於對照組有略高的誘發量，由此資料推估各佃地區之福壽螺，可能已受到環境中類雌性素的曝露與影響。本研究團隊將深入探討福壽螺對於類雌性素的監測適用性，並期待福壽螺於未來可作為監測環境中，類雌性素物質之模式生物。

Endocrine disruption chemicals-also called environmental hormones that mimic normal hormones, affects function of endocrine disordered in animals and person. Vitellogenin is a useful biomarker to inspect xen-estrogenic, likes DDT, NP (nonyl phenol) and BPA (bisphenol A) in aquatic system. The purpose of this study was to investigated the probably of monitor xenoestrogen in apple snail, Pomacea canaliculata. This preliminary research detected vitellogenin in hepatopancreas of apple snail, which collected from different area in Taiwan. Our results showed that concentration of vitellogenin in apple snail of September was highest then February. It is therefore reasonable to speculate that the xenoestrogens in particular, released from agricultural activities, induced vitellogenin in apple snails, that maybe a useful biomarker to monitor of xenoestrogens in aquatic system.
