“…Most intensive horticulture areas or peri-urban farms have been studied ( Polder et al, 2016 ; Zhang et al, 2013 ). Soilless cultures were also addressed ( Savvas & Gruda, 2018 ) but were mainly used for modelling studies and did not reflect real case risks ( Ni et al, 2018 ; Yang et al, 2019 ).…”

Attention to urban agriculture (UA) has recently grown among practitioners, scientists, and the public, resulting in several initiatives worldwide. Despite the positive perception of modern UA and locally grown, fresh produce, the potential food safety risks connected to these practices may be underestimated, leading to regulatory gaps. Thus, there is a need for assessment tools to evaluate the food safety risks connected to specific UA initiatives, to assist practitioners in self-evaluation and control, and to provide policy makers and scholars a means to pursue and assess food safety in city regions, avoiding either a lack or an excess of regulation that could ultimately hinder the sector. To address this aim, this paper reviews the most recent and relevant literature on UA food safety assessments. Food safety indicators were identified first. Then, a food safety assessment framework for UA initiatives was developed. The framework uses business surveys and food analyses (if available) as a data source for calculating a food safety index for single UA businesses and the whole UA landscape of a given city region. The proposed framework was designed to allow its integration into the CRFS (City Region Food System) toolkit developed by FAO (Food and Agriculture Organization of the United Nations), RUAF foundation (Resource Centres on Urban Agriculture and Food Security) and Wilfrid Laurier University.

“…H. vulgaris Lam is well-known for its efficient sewage purification and is frequently employed as an alternative aquatic plant for remediating landscape water pollution [6,16]. However, the combined use of phytohormones and H. vulgaris Lam for eutrophic water remediation has not been extensively researched.…”

Phytohormones have the potential to enhance the nutrient removal efficiency of aquatic plants in wastewater treatment. Here, we investigated the impact of indoleacetic acid (IAA) on nitrogen removal by Hydrocotyle vulgaris Lam during the remediation process of eutrophic water. This investigation involved evaluating the biological indicators of H. vulgaris Lam, the nitrogen salt removal efficiency in eutrophic water, as well as analyzing the bacterial structure and function in both the rhizosphere and eutrophic water surrounding H. vulgaris Lam. The results indicated that surface-sprayed 50 mg/L IAA significantly stimulated the growth of H. vulgaris Lam, including parameters such as blade number, leaf area, petiole length, stem thickness, stem length, and root length of H. vulgaris Lam. Furthermore, exogenous application of IAA significantly accelerated the nitrogen removal of NH4+−N, NO3−−N and total nitrogen (TN) in eutrophic water by promoting the NH4−N uptake of H. vulgaris Lam and NO3−−N denitrification. These findings suggest a potential application for exogenous IAA to enhance the nitrogen removal of H. vulgaris Lam in eutrophication control.

“…pennywort can remove prometryn from hydroponic media (Ni et al, 2018, Sun et al, 2016b, Compared with the efficiency of Vetiver grass and marsh pennywort for removal of prometryn from hydroponic media, Canna indica is also a good potential candidate for removal of prometyn. Possibly, these plants can be used for phytoremediation (Sun et al, 2016).…”

The aim of this study was to the removal potential of 2,4-bis (lsopropytamino)-6-methylthio-s-triazine by Canna from hydroponic media. Green house study was carried out to investigate the potential of Canna as phytoremediation of prometryn. Liquid-liquid extraction was used for extracting prometryn from nutrition solution. Solvent ultrasonic extraction was used for extracting prometryn from the plant and Gas Chromatography-Mass Spectrometer was used for determination.-1 The results showed that. Canna could grow well in the prometryn spiked (0.5mg.l) nultrient solution. Canna uptake and removal of prometryn from the media were monitored for a period of first order 0.042t-0.232t 2 kinetics, C =0.06023e , R =0.9078 (without Canna), C =1.219e (with Canna), R =0.8191. The t 2 t dissipation half-life (T) was shortened by 17days, the dissipation time required for 99%(T) prometryn 1/2 0.99 was shortened from 109 days (without Canna) to 20 days (with Canna). Combined analysis with kinetic of prometryn in the solution and in the plants, the possible prometryn degradation by Canna occurred between day10 and day16. The prelimilary result was encouraging and selected ways of prometryn removal.
