The use of in-situ deployments to examine the success of water quality mitigation measures on a watercress farm

摘要

Watercress has long been believed to affectmacroinvertebrate communities in chalk streams.Harvesting and washing watercress damages plant tissuesand releases isothiocyanates which are potential toxicantsto Gammarus pulex (L.). This study examined whether impacts on G. pulex of watercress farm factory wash water could be mitigated by treating via recirculation through the watercress beds.
