Lemon Juice and Ascorbic Acid Effect on the Metals Extraction from Chamomile, Human Risk Assessment.

The total content of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in chamomile sample, metals content in water chamomile infusions and water infusions with additions of ascorbic acid and lemon juice at different temperatures (70, 80, and 100 °C) and steeping times (3, 5, and 7 min), were determined. The content of heavy metals was determined by flame atomic absorption spectrometry (FAAS). Mean total concentrations of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were 0.

Health risk assessment of heavy metals in PM and PM in Sarajevo air, Bosnia and Herzegovina.

The concentrations of eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) associated with PM and PM in Sarajevo air, Bosnia and Herzegovina (BiH) have been studied. A total of 136 PM and PM samples were simultaneously collected from 21 February to 11 November 2020. Metal contents were determined by atomic absorption spectrometry, flame (FAAS) and electrothermal (ETAAS) techniques.
