Secondary standard of environmental quality standard for soils (China, 6.5 < pH < 7.5); ^bscreening values for environmental risk assessment of sites under residential land use pattern (Beijing, China); ^cRSLs under residential land use pattern (USEPA); ^dEco-SSLs (higher plants as protected objects). ND: some pollutants are not detected. NA: some pollutants are nonexistent in one standard.
