Data from the Edinburgh Lead Study are used to estimate the respective contributions of water and dust lead to blood lead in 6-9 year old children. Both sources are significantly related to blood lead. An exposure of 100 μg/l in kitchen cold water i

The influence of blood lead levels on measures of inspection time (IT) and reaction time (RT) was studied in a sample of 501 6- to 9-year-old children. Both IT and RT performance were worse at higher blood lead levels, but the relationship was strong

The importance of lead‐in‐air as a direct source of exposure for 6–9 year old children is assessed using weekly lead‐in‐air concentrations measured at three sites in Edinburgh over the period April 1983 ‐ May 1984. The selection of sampli

Adsorption of Cd, Pb and Cu (pH 7) has been studied as a function of time during the slow oxidation (24 hr.) of ferrous iron naturally present in samples of anoxic lake water. A simple surface complexation model fits the Cd and Pb behaviour. Initial

A recently established technique for size fractionation of particulate matter in freshwaters, based on low volume filtration through Nuclepore filters in the field, has been applied to the study of Fe and Mn species in 3 freshwater lakes and a stream

The variability of household dust lead concentration and loadings over the period of about a year has been examined in 10 homes. The overall uncertainty on a single sample is ± 65% for lead concentration and ± 81% for lead loading. Redecoration inv

The speciation of Mn has been determined in 15 rivers and streams representing a wide variety of physico-chemical conditions. Using the technique of anodic stripping voltammetry (asv), specific for reduced Mn(II) species, it is found that a major par

SUMMARY. 1. Concentrations of cadmium are reported for twenty largely unpolluted freshwaters in north-western England. They range from 15 to 117 ng l−1 total Cd in the rivers and streams and from 18to51 ng l−1 in the lakes, lying on the low side

Adsorption (co‐precipitation) of Ca, Cd, Cu, Ni, Pb on hydrous ferric oxide (HFO) has been investigated under natural conditions. Ferrous iron (ca 6.8 × 10−5 M) present in samples of anoxic lake water was oxidised under controlled conditions to
