Occurrence of fipronil and its biologically active derivatives in urban residential runoff.
Results of this study clearly established residential drainage as a direct source for pesticide contamination in urban waterways, and for the first time, identified fipronil as a new and widespread contaminant with potential ecotoxicological significance.
Transformation and sorption of fipronil in urban stream sediments.
Results from this study showed that the stability of fipronil in sediments depends closely on the oxygen status and that due to the readily conversion of fIPronil to the sulfone and sulfide metabolites, the overall risk assessment of fipsonil in surface aquatic systems should take into consideration fipronsil as well as its metabolites.
Persistence and sorption of fipronil degradates in urban stream sediments
Sorption coefficient K(d) increased up to fourfold over 280 d, suggesting an aging effect on sorption, and the importance for a better understanding of the sediment toxicity of fipronil degradates in surface water bodies is highlighted.
Managing urban runoff in residential neighborhoods: Nitrogen and phosphorus in lawn irrigation driven runoff
The investigation of the transport of nitrogen (N) and phosphorus (P) in lawn irrigation driven surface runoff from a residential neighborhood of 56% impervious and 44% pervious areas suggests that N and P originating in Lawn irrigation drivensurface runoff from residential catchments is an important contributor of nutrients in surface waters.
Water Use and Treatment in Container-Grown Specialty Crop Production: A Review
This review focuses on multiple facets of water use, reuse, and runoff in nursery and greenhouse production including current and future regulations, typical water contaminants in production runoff and available remediation technologies, and minimizing water loss and runoff (both on-site and off-site).
A cost analysis for using recycled irrigation runoff water in container nursery production: a Southern California nursery case study
In the U.S., container plant growers use high-quality water sources which can be expensive. The use of recycled irrigation runoff water could save growers money. The objective of this study was to
