The United States Pharmacopeial Convention, Inc. recommends within the standards of the United States Pharmacopeia that compounding pharmacies have staff dedicated to quality assurance and quality control to ensure patients are receiving safe medications. The quality-control program must include testing. While compounding pharmacies have grown familiar with potency, sterility, and endotoxin testing, there are many more tests recommended within the United States Pharmacopeia that are critical for evaluating the quality of compounded p

Traditional Pb isotopic identification only based on total Pb concentration and Pb isotopic ratios, resulted in difficulty for tracing Pb sources in the complex environmental medium, especially for sediment. Herein, a novel approach combining with regional geochemical baseline (RG and Pb isotopic ratios are used to directly trace anthropogenic Pb sources and calculate Pb source appointments in sediment. In this study, total Pb concentrations and isotopic ratios were analyzed for a 7-m long sediment core (92 sediment samples
