| Domestic survey of organic contaminants in surface water usually analyzes regulatory compounds and seldom covers those contained in consumer products. Positive relationships between the compound-specific instrumental results and traditional TOC, COD, and BOD results are seldom observed. Additionally, the regulatory compounds are often present in trace amounts and corresponding analytical results can not help identifying the contaminating source or reflecting the background information. In this study we depended on GC-MS having the capability of both separation and determination of analytes including drugs, wastewater related compounds, steroids and hormones. The result detected and confirmed included caffeine, 2,6-di-tert-butylphenol, acetophenone, butylated hydroxy toluene, carb-aryl,diethylphthalate, 4-nonylphenol, phenol, and phthalic anhydride. Caffeine stimulant detected only in Hsinchu river indicates that the local residents have adopted western life consuming more coffee. The presence of the aforementioned analysis provides the background information about each river and the contaminants. |
