Hair and toenail arsenic concentrations of residents living in areas with high environmental arsenic concentrations.
Surface soil and groundwater in Australia have been found to contain high concentrations of arsenic. The relative importance of long-term human exposure to these sources has not been established. Several studies have investigated long-term exposure to environmental arsenic concentrations using hair and toenails as the measure of exposure. Few have compared the difference in these measures of en...
متن کاملDiet and toenail arsenic concentrations in a New Hampshire population with arsenic-containing water
BACKGROUND Limited data exist on the contribution of dietary sources of arsenic to an individual's total exposure, particularly in populations with exposure via drinking water. Here, the association between diet and toenail arsenic concentrations (a long-term biomarker of exposure) was evaluated for individuals with measured household tap water arsenic. Foods known to be high in arsenic, includ...
متن کاملProlonged exposure to arsenic in UK private water supplies: toenail, hair and drinking water concentrations.
Chronic exposure to arsenic (As) in drinking water is an established cause of cancer and other adverse health effects. Arsenic concentrations >10 μg L(-1) were previously measured in 5% of private water supplies (PWS) in Cornwall, UK. The present study investigated prolongued exposure to As by measuring biomarkers in hair and toenail samples from 212 volunteers and repeated measurements of As i...
متن کاملToenail arsenic concentrations, GSTT1 gene polymorphisms, and arsenic exposure from drinking water.
Toenail arsenic (As) concentrations were evaluated as a biomarker of inorganic As (As(in)) exposure in a population residing in an As-endemic region of Bangladesh. Drinking water and toenail samples were collected from 48 families (n = 223) every 3 months for 2 years and analyzed for As using inductively coupled plasma-mass spectrometry. Drinking water collected 3, 6, and 9 months before each t...
متن کاملUrinary arsenic concentrations and speciation in residents living in an area with naturally contaminated soils.
A cross sectional study was carried out to evaluate arsenic exposure of residents living in an area with a soil naturally rich in arsenic (As), through urinary measurements. During the summer of 2007, 322 people aged over 7 years and resident in the study area for at least 4 days prior to the investigation were recruited. The sum of urinary inorganic arsenic and metabolites (iAs+MMA+DMA) and sp...
