The effects of zinc on the structure and functioning of a freshwater community: A microcosm experiment.

abstract：:Recently we showed that tetracyclines tend to persist and may accumulate in sandy soils after repeated fertilizations with liquid manure. We continued these field investigations from 2001 to 2003 and observed no further accumulation of tetracyclines in soil, but found that the average tetracycline concentration remain...
