摘要:Abstract: In order to investigate Pb pollution causes in Jintan inarticulate water dropwort (Oenanthe stolonifera) and the control technologies, soils, irrigation water, fertilizers and water dropwort products were sampled to test Pb concentrations in the production areas. The results showed that Pb concentrations in all soil and fertilizer samples were below the maximum allowable concentrations (MAC, according to the Chinese Standards) for safe production, but Pb concentrations exceeded the MAC in 18.2% of the irrigation water samples. When Pb concentration in the irrigation water reached the MAC (0.05 mg/L, NY 5010-2002), Pb concentration of water dropwort was 0.263 mg/kg, which was 163% higher than the MAC for water dropwort (0.1 mg/kg, GB 2762-2012). Further analysis indicated that there was positive and highly significant (r = 0.7980, P < 0.01) correlation between irrigation water and Jintan inarticulate water dropwort in Pb concentrations. There- fore, the Pb pollution in irrigation water is the main cause for Pb accumulation in Jintan inarticulate water dropwort. The secondary cause for Pb pollution of Jintan inarticulate water dropwort is deep water cultivation. The results reveal that Pb concentration in the irrigation water, for safe production of Jintan inarticulate water dropwort, must be controlled below 0.03 mg/L.
