Crayons and colored pencils for children may contain toxic elements (TEs) exhibiting potential risk children?s health including cognitive development, after their ingestion, through mouthing chewing eventually, accumulation. The aim of this study was to determine total content As, Pb, Cr, Cd, Ni Sb estimate bioaccessibility conducting artificial saliva extraction. Sixty samples crayons from 10 ...

The concentrations of As, Cd, Hg, Ni and Pb were determined in fifteen sunflower honey samples collected from 9 locations the Republic Serbia during 2019. elements analysed using inductively coupled plasma mass spectrometry (ICP-MS). Mean levels (mg kg-1) all as follows: 0.004 for 0.003 0.077 0.051 Pb. mercury content was below detection limit applied method (< 0.001 mg Hg kg-1 honey). lead ...

This study was conducted to highlight status and distribution of potentially toxic elements (PTEs) in Usangu agroecosystem-Tanzania. The involved 198 soil samples from 10 irrigation schemes including three land use. concentrations selected PTEs (Cd, Cr, Cu, Pb, Zn, As, Hg, Co, Nie etc.) were determined estimate status, distribution, contamination hierarchy. total bioavailable by aqua regia dige...
