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 […]
