DR. BHARAT CHANDRAMOULI OF SGS TO PRESENT ON PFAS MONITORING AT WASTEWATER TREATMENT PLANTS AT ECOS VIRTUAL CONFERENCE, JULY 29

PFAS in wastewater and biosolids present a difficult challenge as they are not removed/destroyed through conventional treatment. The conversion of precursors into persistent perfluorinated carboxylates and sulfonates during treatment poses further human and ecological risks. To discuss this issue, Bharat Chandramouli, Ph. D., Environmental Laboratory Product Manager, North America at SGS, joins an expert panel […]

Orange pill between white ones

SGS AXYS is a leader in the measurement of pharmaceuticals and personal care products (PPCPs) in the environment. Our methods were used as the basis for EPA Method 1694 in 2007 and these isotope-dilution LC-MS/MS PPCPs methods has since expanded to include close to 200 drugs, metabolites, hormones and personal care products. From natural and […]

Bile Acids Interferences in PFAS Analysis

Bile acids structure and name

Can bile acids found in plasma, eggs, liver and other biological samples interfere with PFAS analysis? Yes! But there are ways to avoid these interferences and produce reliable data. Bile acids and their salts are either synthesized in the liver or formed from bacterial activity. They are the major constituents of bile and help digest […]

SGS AXYS Data Used to Assess Phthalate Levels in Children

Phthalates, used as plasticizers in many plastics including polyethylene, polypropylene and more, have been associated with endocrine disruption. But, given their ubiquity in the environment, it is challenging to really pinpoint exposure in humans. Phthalates are metabolized in the body into monophthalate ester metabolites and excreted in urine. So, measuring these phthalate ester metabolites in […]

SGS AXYS Scientists Publish Timely Study on PFAS Storage Stability

While perfluorinated carboxylates and sulfonates (PFAA) such as PFOA and PFOS are known to be stable under all storage/environmental conditions, it is well known that many other PFAS, including PFAA precursors can transform in the environment from biological and chemical processes. But little was known about their stability in environmental samples sent to laboratory and […]
