JAMA: The Journal of the American Medical Association, 1987
To the Editor.— I read with interest the editorial entitled "Now Read This: The SI Units Are Here," published in the May 2, 1986, issue of JAMA . 1 In Table 3—"Examples of Conversions to Systeme International (SI) Units"—I was concerned to find values for lead in blood that may be confusing to clinicians.

Blood lead levels in children, China
Environmental Research, 2006To evaluate Chinese children's blood lead levels (BLLs) and identify its distribution features, we collected articles on children's BLLs published from 1994 to March 2004 using the Chinese Biomedical Disc and reviewed 32 articles eligible for the following criteria: (1) BLLs measured by Graphite Furnace Atomic Absorption Spectroscopy or Inductively ...

Blood lead levels in incinerator workers
Environmental Research, 1992Questions have been raised concerning the safety of mass burn incineration and its role in solid waste management. In 1989, the New York City Office of Occupational Safety and Health examined air levels of metals in New York City incinerators and found that workers were exposed to air lead levels as high as 2500 micrograms/m3 while cleaning the ...

Blood lead levels in Queensland children
Medical Journal of Australia, 1982Venous blood lead levels are reported for 514 children from one year to 16 years of age. The blood samples were obtained from children referred to the royal children's hospital, Brisbane, for various reasons. The results are compared with criteria announced by the national health and medical research council and other internationally recognised bodies.

Blood Lead Levels in Glue Sniffers
Biological Trace Element Research, 2004The aim of this study was to investigate blood levels of lead (Pb) among adolescents with glue sniffing in Turkey. Blood Pb levels were measured in 30 adolescent glue sniffers by atomic absorption spectrophotometry and compared with those of the 30 healthy adolescents.

Blood Lead Levels In Victorian Children
Medical Journal of Australia, 1980A recent study of lead levels in the blood of Sydney schoolchildren purported to show "an alarming situation of epidemic proportions", with up to 24% of children in one survey having blood lead levels greater than 25 microgram/100 mL (1.21 mumol/L). In the present study, 446 Victorian children were tested for lead level in venous blood, showing a mean ...

Science of The Total Environment, 1991
Blood lead levels were experimentally elevated in two subjects by ingestion of single oral doses of lead as lead chloride. Serial samples of blood, urine and sweat were collected subsequently. Sweat samples were collected in polythene armbags while subjects cycled on a bicycle ergometer in a hot chamber.

In a state-wide survey of lead poisoning in Illinois, blood specimens were obtained from 6,151 children ages 1 to 6 years who resided in 14 Illinois cities of intermediate size (10,000 to 150,000 population). Of the total number tested, 1,147 (18.6%) were found to have evidence of undue absorption of lead (greater than or equal to 40μg/100 ml) while ...

DESPITE DRAMATIC REDUCTIONS IN POPULATION LEAD exposure over the past 2 decades, nearly 900 000 US children younger than 6 years still have elevated blood lead levels ($0.483 μmol/L [$10 μg/dL]). The problem disproportionately affects lowincome children living in older dwellings.

Erythropoiesis, erythropoietin and blood lead levels.
Giornale italiano di medicina del lavoro ed ergonomia, 2009In a previous study EPO values were significantly lower in exposed subjects (PbB > or =30 mcg/dl) than in controls (PbB" 20 mcg/dl). The aim of the study was to verify if high PbB cause the reduction of EPO in connection with the serum concentration of this hormone expected considering the Hct and hemoglobin (Hb) levels.
