Abstract

The quantity and spectroscopic features of dissolved organic matter (DOM) in treated wastewaters were studied for up to 57 facilities across 12 industrial categories to evaluate the potential influences of the effluents on downstream ecosystems and the feasibility of spectroscopic techniques in discriminating pollution sources. The average dissolved organic carbon (DOC) concentration was 3.30±0.70-73.4±14.0 mg L(-1) for each category, high enough to pollute downstream waterbodies. The average specific UV absorbance at 254 nm (SUVA) for each category spanned a broad range between 0.79±0.24 and 5.35±1.41 L(mg m)(-1), suggesting a variable aromaticity of DOM. Fluorescence excitation emission matrix-parallel factor analysis (EEM-PARAFAC) identified four humic-like and two protein-like components. The EEMs were grouped into seven clusters, five of which were dominated by a single PARAFAC component in each cluster. Fourier transform infrared (FT-IR) spectroscopy revealed notable variations in relative intensities of several characteristic absorbance bands among different wastewaters. The large variability in SUVA, PARAFAC and FT-IR features indicated that the chemical composition of DOM greatly differ among industrial wastewaters, an...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
