Terrestrial exposure of oilfield flowline additives diminish soil structural stability and remediative microbial function

► Effects of flowline additives on soil structure and microbial function highlighted. ► Phosphonate salts (in scale inhibitor) were found to disrupt soil physical structure. ► Glutaraldehyde (in biocides) caused significant reduction of hydrocarbon degradation in soil. ► Flowline additive chemicals synergistically affects soil structure and remediative microbial function.
