| concentrations of host-specific and generic fecal markers measured by quantitative pcr in raw sewage and fresh animal feces. | we measured the concentrations of four host-specific (human, dog, cow, and horse bacteroidales), four generic fecal (16s total bacteroidales and escherichia coli, 23s enterococcus and uida e. coli,) and two universal bacterial (16s universal and rpob universal) dna targets by qpcr in raw sewage and pooled fecal samples from dogs, cows, horses, and canada geese. a spiking protocol using the non-fecal bacterium pseudomonas syringae pph 6 was developed to estimate the recovery of dna from fecal and ... | 2009 | 19765792 |
| strontium-90 in canada goose eggshells and reed canary grass from the columbia river, washington. | strontium-90 ((90)sr) released to the ground near the n reactor at the u.s. department of energy's hanford site enters the columbia river through shoreline seeps. the (90)sr is then potentially available for uptake by plants and animals. the life history and foraging behavior of nesting canada geese is such that female geese could ingest (90)sr while foraging on shoreline plants. radichemical analyses showed that goose eggshells taken from an island, downstream from the n reactor, contained more ... | 1990 | 24243258 |
