Lead –Pollution and its Effect on Blood Indices Around the Ravar-Feyz abad-Lead Minee
Abstract
Lead has been recognized as an environmental pollutant of cancer for humans for livings for years. The lead concentration in biological cycles seems to depend on several factors, such as soil properties, plants species, and water properties as well as other factors. The objective of this study was to assess the rate of mobility and determine its effect on blood indices around the feyz abad – lead mine. The first part of this study showed a high lead level in water, soil and plant samples (compaired with anther area). To check the details, a blood sample of the male workers who were selected by a questionnaire was gathered (n=24 as the experimental group). Then, HCT, MCV, MCHC, MCH, Hg and RBC factors were measured. Finally, a comparison was made between the sampling data and 24 males unexposed to lead who were from Ravar (as the control group).The results indicated that HCT and Hg were significantly lower in the experimental group than the control group. RBC, MCV, MCHC and MCH showed no significant variation. It is concluded that the lead compounds in Feyz Abad can enter the biological cycle and then absorbed by tissues such as bone marrow and induce variation on blood indices.
