摘要：Objectives: Lead (Pb) pollution is a serious public health problem all over the world, it especially plays severe damage role in children’s health. Apart from reducing lead-induced damages, the decrease of lead accumulation is also critical. This study has been the first attempt to investigate effects of meso-2,3-dimercaptosuccinic acid (DMSA), potassium iodide (KI) and chlorophyll (Chl) on lead accumulation in male mice. Material and Methods: Eighty healthy Kunming male mice were selected and divided randomly into 8 groups. They were treated with lead acetate (PbAc) intraperitoneally, individually and in combination with the DMSA, KI or Chl once daily for 5 days. Meanwhile, the control group was treated with normal saline during the whole exposure period. On 30th day, mice were sacrificed and lead concentrations were detected in the whole blood, livers, kidneys, and testicles of mice by means of the graphite furnace atomic absorption spectrometry. Results: In comparison with the control group, lead concentrations increased in mice treated with the PbAc and DMSA, KI and Chl diminished lead accumulation in the whole blood, livers, and kidneys. Chl had specifically the same effects on lead concentrations in the testicles of male mice. Conclusions: Potassium iodide and Chl, as food additives, had the same effects as the DMSA to reduce lead accumulation in male mice effectively. Our results provided experimental evidence in vivo for the preventive measures of lead poisoning. Int J Occup Med Environ Health 2017;30(1):87–93
