摘要
This study was conducted to assess th.e existing concentration of 17β- estradiol (E2) in the surface watersamples collected from rivers and lakes around Klang Valley, Malaysia. E2, which is a natural feminizing chemical pro-duced in female organisms, regularly used to compare with other environmental estrogens because they behave similarlyand react effectively as a hormone at a very low concentration. It was found that the average concentration of E2 in theaquatic environment of Klang Valley was ( 14.08 +3.67) pg/mL, which was 14 times higher than those in the Japaneseaquatic environment in this study. The river system had the average concentration of (20.02 +5.26) pg/mL while thelake had an average concentration of (5.91+.39) pg/mL. The E2 concentration was presumed high if the sourcesoccurred nearby the area. Current levels of E2 in the aquatic environment may possess threats to existing aquatic organ-isms. Since high level of E2 has been discovered in the aquatic environment around Klang Valley, furcher studies andmonitoring of E2 and other EDCs concentrations are needed to determine their levels in Malaysian aquatic environmentand help to control these chemicals pollution in the aquatic environment.
