“…Indeed, in our work the leaf concentration of all considered nutrients remained within the sufficiency ranges reported for sweet basil (Zheljazkov and Warman, 2003); therefore, the remarkable growth reduction observed in plants treated with KI cannot be explained by iodine-induced mineral deficiencies. Similar conclusions were reported for barley by Duborská et al (2018) and for lettuce by Blasco et al (2012) and Smoleń et al (2014a).…”

“…Many studies showed that the plant response to iodine application is variable according to the chemical form used (iodide, I − ; iodate, IO 3 − ; iodoacetate, ICH 2 COO − ), the concentration applied, and the growing system (Medrano-Macías et al, 2016;Duborská et al, 2018). Iodine toxicity is reported in the order I 2 (aq) > I − > IO 3 − (Mackowiak and Grossl, 1999;Dai et al, 2009).…”

“…In contrast, significant research has been devoted to iodine biofortification, as confirmed by the numerous studies on the application of I − and/or IO 3 − to various crop species. According to a review by Medrano-Macías et al (2016), most of the work has been conducted on vegetable crops (more than 12 different species), such as lettuce (Smoleń et al, 2014a), spinach (Zhu et al, 2003;Smoleń and Sady, 2012), tomato (Caffagni et al, 2011;Kiferle et al, 2013;Smoleń et al, 2015b), and on cereals such as rice (Kato et al, 2013), wheat (Mao et al, 2014), and barley (Duborská et al, 2018).…”

Iodine Accumulation and Tolerance in Sweet Basil (Ocimum basilicum L.) With Green or Purple Leaves Grown in Floating System Technique

Iodine deficiency is a serious worldwide public health problem, as it is responsible for mental retardation and other diseases. The use of iodine-biofortified vegetables represents a strategic alternative to iodine enriched salt for people with a low sodium diet. However, at high concentrations iodine can be toxic to plants. Therefore, research on plant iodine toxicity is fundamental for the development of appropriate biofortification protocols. In this work, we compared two cultivars of sweet basil (Ocimum basilicum L.) with different iodine tolerance: "Tigullio," less tolerant, with green leaves, and "Red Rubin," more tolerant and with purple leaves. Four greenhouse hydroponic experiments were conducted in spring and in summer with different concentrations of iodine in the nutrient solution (0.1, 10, 50, 100, and 200 μM), supplied as potassium iodide (KI) or potassium iodate (KIO 3). Plant growth was not affected either by 10 μM KI or by 100 μM KIO 3 , while KI concentrations higher than 50 μM significantly reduced leaf area, total plant dry matter and plant height. The severity of symptoms increased with time depending on the cultivar and the form of iodine applied. Growth inhibition by toxic iodine concentrations was more severe in "Tigullio" than in "Red Rubin," and KI was much more phytotoxic than KIO 3. Leaf iodine concentration increased with the iodine concentration in the nutrient solution in both varieties, while the total antioxidant power was generally higher in the purple variety. In both basil cultivars, a strong negative correlation was found between the photosynthesis and the leaf iodine content, with significant differences between the regression lines for "Tigullio" and "Red Rubin." In conclusion, the greater tolerance to iodine of the "Red Rubin" variety was associated with the ability to withstand higher concentrations of iodine in leaf tissues, rather than to a reduced accumulation of this element in the leaves. The high phenolic content of "Red Rubin" could contribute to the iodine tolerance of this purple cultivar.

“…Nevertheless, a concentration 0.5–1 ppm had a positive effect on barley plants (32). The iodine is most toxic in its iodide form (33). This is the form we used in our experiments at 10,000 ppm concentration.…”

demand (COD; 760 ± 6.6 mg L −1 ) indicating the presence of leachate, explained by its close proximity to the landfill cell. Pond L-03 presented higher parameters compared to pond L-02, except for N-ammoniacal and phosphorus levels, explained by the local geological configuration, configured as a slope from the landfill cell towards L-03. Seven filamentous and/or yeast fungi genera were identified, including the opportunistic pathogenic fungi Candida krusei (4 CFU) in an outcrop sample. Regarding soil samples, Br, Se, and I were present at high concentrations leading to high soil contamination (CF ≤ 6). Pond L-02 presented the highest CF for Br (18.14 ± 18.41 mg kg −1 ) and I (10.63 ± 3.66 mg kg −1 ), while pond L-03 presented
