苯巯基尿酸
苯巯基尿酸-
尿中苯巯基尿酸（SPMA）与苯接触存在良好相关性，是低浓度苯接触特异和敏感的生物标志物。
Since urinary S-phenylmercapturic acid concentration could be well related to benzene exposure , it could be a sensitive and specific biomarker of low-level benzene exposure .

但苯巯基尿酸的测定对仪器要求较高，而反反式粘糠酸检测方法更易被基层接受、普及。
But the detection of S-PMA requires high standards of instrument , while the method of detection of trans , trans-muconic acid is likely to be wide-spread accepted by those poor-equipped departments .
