The Concentration and Availability of Heavy Metals in Municipal Sewage Sludge and Soil in Guangzhou
The concentrations and available contents of heavy metals in sludge and agricultural soils in Guangzhou city are studied. The concentrations of organic matter、N、P in sewage sludge of Datansha sewage treatment plant are high and fertile. The concentrations of heavy metals in sewage sludge are under the criteria for agricultural use. The availabilities of Pb and Cr in sludge are low
but that of Cd、Zn、Cu and Mn are high. The mean concentraton of Cd in arable soil samples is higher than the criteria for agriculture.
