摘要: Lettuce grown in a pot test using the surface soil layer of three golf course sites contaminated with mercurial fungicides contained up to 317 ng Hg/g as compared no more than 36 ng Hg plants corresponding deeper layers containing much less Hg. In another experiment 10 crop species, addition phenylmercuric acetate loam at rate 5,000 ng increased content several species slightly over that found controls. The highest amount was about 440 ng soybean vines and potato tops. concentration tended be lower edible portion (fruit, grain or roots) remainder plants. an incubation where added seven soils two clay-sand mixtures Hg/g, retention against volatilization varied from 41% sandy subsoil 97% peat. Addition flowers sulfur effective preventing soils, ...
