The exposure of lead in workplace air and human workers of battery
manufacturing factory was evaluated determined by nanotechnology
since ۲۰۱۹-۲۰۲۰. Human whole blood (HWB) for subject and healthy
peoples (۲۵-۵۵, Men, ۴۰ N) and workplace air (۴۰N) was prepared
based on NIOSH sampling. ۱۰ mL of HWB samples added to ۲۰
mg of mixture ionic liquid/ ligand ([HMIM][PF۶]/APDC) modified
on graphene oxide nanostructures(GONs) at pH=۶. After sonication,
the lead ions separated/extracted by dispersive ionic liquid solid
phase micro extraction (DIL-SPME) and determined by flame atomic
absorption spectrometry (F-AAS). All air samples in workplace were
analyzed based on NIOSH process. The results showed us the negative
correlation between Pb concentration in human blood subject and
healthy peoples (r=۰.۲۴). The range concentrations of lead in human
subject, healthy peoples and workplace air were obtained ۱۹۳.۴-
۵۴۳.۷ μg L-۱, ۸۵.۶-۱۷۵.۹ μgL-۱ and ۴۴.۷-۸۱.۵ μgm-۳, respectively. The
LOD, linear rang, enrichment factor(EF) and RSD% were achieved
۱.۲۵ μg L-۱, ۵.۰- ۳۱۰ μg L-۱, ۱۹.۶ and less than ۵% by procedure.
The method was validated by standard reference material (SRM), the
electrothermal atomic absorption spectrometry (ET-AAS) and ICPMS
analyzer for human samples.
