Resumo: | ABSTRACT To investigate the health status of public parks in Jeddah city, a field survey was conducted based on the Cyperus rotundus weed and soil analysis of wastewater-irrigated parks during 2012. The city was divided into five different locations (North, South, East, West and Middle) and five parks were randomly sampled from each location; thus, the total number of sampled parks were twenty five. Toxic metals concentration were analyzed in the soil and in the plants while bacterial count was determined from the weed leaves. All studied toxic metals have significantly crossed the European Union safety limits for plant samples, while soil samples were just beyond the limit. The highest concentration was perceived for Lead (133-232 mg kg-1) and was followed by Chromium (80-141 mg kg-1). The microbial analysis of one gram leaf sample of C. rotundus demonstrated a maximum bacterial count of 45,955 cfu g-1, number of total E. coli form 34 and fecal coli form 8.65 at South and East Jeddah locations. These locations have also produced the highest concentration of toxic metals for both plant and soil samples. In crux, C. rotundus weeds may serve as an indicator of parks health by toxic metals and bacterial analysis that may infect the visitors, especially children's playing on it.
