The IMF’s April 2025 Regional Economic Outlook for Sub-Saharan Africa presents a clear warning: regional growth is slowing, debt pressures are mounting, and donor assistance is declining. Yet the report outlines critical opportunities particularly in domestic revenue mobilization, structural reform, and private sector activation that can shape a more resilient …
An analytical procedure was developed to measure bromate residues in baked goods using a sequence of clean‐up procedures followed by high performance liquid chromatography (HPLC) with a post‐column reaction for oxidants. Deionized water was used to extract bromate from bread samples. The extract was treated with a C‐18 solid phase …
Bisphenol-A (BPA) is a principal reactant in the preparation of polycarbonate (PC) plastics and has been shown in in vitro cell proliferation studies to exhibit estrogen-like characteristics. Reusable baby bottles, water carboys, and other housewares are often made of PC. A high-pressure liquid chromatographic (HPLC) protocol was used to determine …
Twenty-four brands of plastic baby feeding bottles were purchased and all were found to be made of polycarbonate. Taking a batch of one representative sample, the polymer was tested for stability and possible release of bisphenol A following domestic practice of sterilization. Sterilization was by alkaline hypochlorite, steam, or washing …
A simple, selective and sensitive high-performance liquid chromatographic (HPLC) method has been developed for the measurement of josamycin residues in four porcine tissues (i.e., muscle, liver, kidney and fat). The sample preparation consisted of a homogenization step in an acetonitrile
This paper reviews recent developments in the liquid chromatographic (LC) methods of analysis for the residues of antibiotics (aminoglycosides, chloramphenicol, sulfonamides, tetracyclines, macrolides, ?-lactams, etc.) in food products of animal origin. The review also covers clean-up procedures, such as, ultrafiltration, liquid-liquid partition, solid-phase extraction, immunoaffinity, and matrix solid-phase dispersion, for …
