Redistribution and persistence of microorganisms and steroid hormones after soil-injection of swine slurry.

摘要: Abstract The redistribution and fate of contaminants in pig slurry after direct injection were investigated at two field sites, Silstrup (sandy clay loam) Estrup loam), Denmark. Intact soil samples collected for up to seven weeks concentrations Salmonella Typhimurium Bacteriophage 28B (phage 28B), Escherichia coli, steroid hormones other components (water, volatile solids, chloride mineral N) determined around the slit. experiments differed with respect solid content (6.3 vs. 0.8%), as well (27 15%) considerably initial slurry-borne soil. transport microorganisms from slit surrounding was much lower than that N due attachment entrapment. E. coli more affected by site-specific conditions compared phage 28B, possibly larger cell size coli. overall recovery 0.8–4%, 0.0–1.3% different samples, end study. Nine detected slit, a slow observed. Overall estrogens 0.0 6.6% samples. study showed combination properties spreading contaminants, hence potential subsequent leaching.
