Low-level exposure to lead, blood pressure, and hypertension in a population-based cohort
Environmental Research, 2016 BackgroundEnvironmental lead exposure is a possible causative factor for increased blood pressure and hypertension, but large studies at low-level exposure are scarce, and results inconsistent.ObjectiveWe aimed to examine the effects of environmental ...

Lead levels in Saliva and in blood
Journal of Toxicology and Environmental Health, 1981The relation between salivary and whole-blood Pb levels was examined in 266 male adults, 196 of whom were Pb-exposed workers. The coefficient of correlation r between salivary and blood Pb levels was .72 (p less than 0.01); the correlation was improved when salivary Pb concentrations were plotted on a logarithmic scale.

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.

Blood lead levels during pregnancy
International Archives of Occupational and Environmental Health, 1981A cross-sectional study of the variation of blood-lead levels throughout pregnancy was carried out on 165 women living in a rural area and 19 women living in an urban area. The mean blood-lead levels of both groups did not differ significantly from those of non-pregnant controls (27 rural and 19 urban).

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 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 ...

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 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 ...
