Investigation on Parabens Occurrence in Romanian WWTP Sludge by LC-MS/MS Method

Abstract:

A sensitive and precise method for detection of five parabens in sewage sludge was developed based on ultrasonic assistedextraction, SPE clean-up and LC-MS/MS. Most of the parameters that affect the extraction step such as type of solvent and volume, extraction time were optimized. For ultrasonic extraction it was used a mixture of methanol: acetone, then the extract was centrifuged in order to obtain clean supernatant and the extract was purified on polymericSPE cartridges. The parabens were separated on C18 column in 13 min at 18şC using a gradient of mobile phase of 0.01% acetic acid and acetonitrile. Using the method, limit of quantitation (LOQ) were obtained ranging from 0.4 to 2ng/g. All recoveries ranged from 71% to 109% for all compounds. The repeatability and reproducibility between days expressed as RSD (%) were less than 7.4% and 14.5%, respectively. The sum concentrations of all parabens for each sludge sample ranged between 19 ng/g dry weight and 32.7 ng/g dry weight. The study of the profile sample composition shows that the average contribution of each compound of the total parabens concentration was as follow: methyl paraben 62.9%, ethyl paraben 18.6%, iso-propyl paraben 10.9%, propyl paraben 10.8%. This result indicate that methyl paraben is the most used paraben followed by ethyl paraben.
