    Essential and non‑essential elements in lettuce produced on a rooftop urban garden in São Paulo metropolitan region (Brazil) and assessment of human health risks
    2022 - SUSSA, FÁBIO V.; FURLAN, MARCOS R.; VICTORINO, MARCOS; FIGUEIRA, RUBENS C.L.; SILVA, PAULO S.C.
    This study evaluated the essential and non-essential elements in lettuce cultivated on a rooftop urban garden in the metropolitan region of São Paulo. In addition, the human health risks associated with the potentially toxic metals based on the estimated daily intake (EDI), the target hazard quotient (THQ), and the possible sources of heavy metal contamination by multivariate statistical were analyzed. The lettuces contain essential macronutrients such as K, Ca, and Mg. The Cd, Cu, and Pb concentrations did not exceed the Brazilian legislation limit. Ba, Ni, Cr, Co, and Pb presented low levels compared to oral reference dose and they may be associated to vehicles emissions. Both EDI and THQ values suggested minimal risk upon consumption of lettuce.

    Soil-to-plant transfer factor for stable elements in lemon balm (Melissa officinalis L.) and estimates of the daily intakes
    2022 - SUSSA, FABIO V.; FURLAN, MARCOS R.; VICTORINO, MARCOS; SILVA, PAULO S.C. da
    This study evaluated the transfer factor (TF) of stable elements from soil to Melissa officinalis and the estimated daily intakes for potentially toxic elements. INAA, GFAAS, and ICP-OES techniques were applied to determine the elemental concentration. Br, Ca, Cd, K, Ni, and Rb accumulated the most with the TF (> 1.0), followed by Ba, Co, Cr, Cu, Mg, Mn, Na, Pb, Sb, and Zn (0.1–1.0), while As, Fe, Hf, La, Sc, Sm, Th, Ti, and V had the lowest accumulation (< 0.1). The daily intake (μg day− 1) of As (1.35–10.35), Br (22.5–297), Cd (0.09–0.54), Cr (220–1,270), Cu (31.5–76.5), Ni (0.09–0.54), Pb (4.5–31.5), and Zn (139.5–400.5) even overestimated was still lower than values established by WHO/FAO.
