"Crop irrigation with reclaimed water is becoming increasingly popular due to water shortages exacerbated by climate change and variability. Pharmaceuticals in reclaimed water may pose unintended food safety risks when they accumulate in crops. Understanding the uptake pathways and accumulation levels of pharmaceuticals in crops under typical irrigation practices is critical for accurate risk assessment of crop irrigation using reclaimed water. The objectives of this study were to investigate the uptake of pharmaceuticals by greenhouse-grown lettuce irrigated with pharmaceutical-contaminated water via overhead or surface irrigation." -- Abstract.
