The accumulation of zinc (Zn) in Cichorium intybus and effects of phytotoxicity during 90 days of growth on (natural) non-contaminated and Zn-contaminated soils were studied. The phytotoxicity effects were monitored by evaluating the leaf area, leaf biomass, leaf length and root length of the vegetable. The Zn concentrations ranged from 5.35 ± 1.05 to 37.5 ± 3.89 mg kg⁻¹ in leaves of plants grown on natural soil, and from 334.0 ± 25.6 to 2232 ± 16.7 mg kg⁻¹ when grown on Zn-contaminated soils. Zn accumulation caused a decrease in growth on contaminated soils and an increase in phytotoxicity. These effects were associated to high metal concentration, mobility and bioavailability in the soil as well as changes in the translocation mechanism from the roots to the leaves. Then, it must be avoided the organic fertilization of soils with either animal manure or other agricultural inputs containing high zinc concentrations.

研究了菊苣（Cichorium intybus）中锌（Zn）的积累以及90天生长对（天然）未污染和Zn污染土壤上植物毒性的影响。通过评估蔬菜的叶面积，叶生物量，叶长和根长来监测植物毒性作用。在天然土壤上生长的植物叶片中，锌的浓度范围为5.35±1.05至37.5±3.89 mg kg ^-1，范围为334.0±25.6至2232±16.7 mg kg ^-1当生长在受锌污染的土壤上时。锌的积累导致受污染土壤的生长减少，植物毒性增加。这些影响与土壤中高浓度的金属，迁移率和生物利用度以及从根到叶的转运机制的变化有关。然后，必须避免使用动物粪肥或其他含锌量高的农业投入物对土壤进行有机肥。
