Phytodiversity for Metals in Plants Grown in Urban Agricultural Lands Irrigated with Untreated City Effluent

Urban Farm DB summary

This study investigated metal accumulation in plants grown in urban agricultural lands irrigated with untreated city effluent in developing countries. Sewage samples showed hazardous electrical conductivities, sodium adsorption ratios, and residual sodium carbonate for irrigation, although metal levels were near permissible limits. Critically, plants acquired metal contents that were greater than those found in the raw sewage or soils, indicating significant metal uptake.
