Twenty-two including eleven four one lincosamide, were detected with total contents up 3870 ng/g. The individual ranged 0.66 3310 ng/g, their detection frequencies between 2% 49%. composition varied significantly, depending on raw materials, production processes, source regions. Seven ciprofloxacin, enrofloxacin, tilmicosin, low medium potential organisms amended soils. wide indicate urgent need establish regulatory limits antimicrobial control prevent pollution brought by amendment.
