Abstract

Both occupational and environmental exposures to lead remain a serious problem in many developing and industrializing countries. When humans are exposed to high levels of lead, there is damage to almost all organs and organ systems (most importantly, the central nervous system, kidneys, and blood), which often culminates in death. To estimate the prevalence of blood lead levels (BLLs) and to identify the sources of environmental exposure and potential risk factors for elevated BLLs among Saudi schoolchildren. A cross-sectional survey was conducted from March to May 2010. The study population included 557 Saudi school students of both sexes. A multistage random sampling technique was used. Information about socioeconomic status, house and school construction, and parents' education and employment was collected using questionnaires. Lead was analyzed in a blood sample using an atomic absorption technique and hemoglobin was measured using a Sysmex hematological analyzer. The mean BLL was 4.94 ± 3.38 μg/dL (range 0.45-26.3 μg/dL). A total of 19% had BLLs <1.0 μg/dL, 16% had BLLs <2.5 μg/dL, 15% had BLLs <5.0 μg/dL, 20% had BLLs <7.5 μg/dL, 25% had BLLs <10.0 μg/dL, and about 6% had BLLs >10.0 μg/dL. Analysis of odds by controlling ...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
