To quantify the leaching of bisphenol A into water, various samples of plastic waste were cut into small pieces, soaked in water for two weeks at room temperature in the dark, and the concentration of bisphenol A in the water determined by gas chromatography/mass spectrometry (GC/MS). The amount of bisphenol A leached from the plastic wastes ranged from undetectable to 139 micrograms/g. The detection limit was 2 ng/g when 100 g of plastic waste was used. Polyvinyl chloride products yielded the highest concentrations because bisphenol A is used in its manufacture as a stabilizer.
为了量化双酚A向水中的浸出情况，将各种塑料废弃物样品切成小块，在室温黑暗条件下于水中浸泡两周，然后通过气相色谱/质谱联用仪（GC/MS）测定水中双酚A的浓度。从塑料废弃物中浸出的双酚A量在检测不到至139微克/克之间。当使用100克塑料废弃物时，检测限为2纳克/克。聚氯乙烯产品产生的浓度最高，因为双酚A在其制造过程中用作稳定剂。
