Influence of organic amendments used for benz[a]anthracene remediation in a farmland soil: pollutant distribution and bacterial changes

Purpose Organic amendments are usually carried out at field-scale for efficient remediation of organic pollutants; however, their effects on pollutant distribution and the corresponding microbial mechanisms were rarely discussed. The main aim of this study was to compare the fate of benz[a]anthracene in soil amended by several bioremediation materials and underlying microbial mechanisms.
