Application Note 645
Develop an HRAM-based LC-MS/MS workflow to quantitatively analyze contaminants of emerging concern (CECs) in biosolids samples and to screen for 381 non-targeted CECs.
• A rapid dilute and shoot method for the quantitative determination of targeted CECs, such as endocrine disrupting chemicals, pharmaceuticals, personal care products, as well as their degradation by-products, has been developed.
• Using ultrasonic-based sample preparation and HPLC-Orbitrap MS analysis without any sample cleanup, this method has been optimized for the determination of 49 CECs present in biosolids and terrestrial biomes exposed to biosolids-amended soils.
• Semi-quantitative results showed the presence of surfactants, musks, and treatment by-products in biosolids.
• Efforts to obtain analytical standards to complete the studies are on-going.
