## Abstract **BACKGROUND:** The biodegradable organic matter and the initial carbon–nitrogen ratio can be substantially different in different batches of sewage sludge, which results in a difference in the acidification efficiency of sludge. Using sewage sludge from three different sources, batch t
We have previously shown that humic acid (well-water humic acid, HA, and synthetic humic acid, SHA) enhances cell surface expression of tissue factor (TF). Here we report that incubation of human umbilical vein endotheiial cells (HUVEC) for 2 hr with HA or SHA cause a rapid rise In TF mRNA levels, a
