    Notes: Abstract Trace element concentrations in soils, plants and animals in National Parks and Wildlife Reserves in Kenya are assessed using geochemical mapping techniques. Soil trace element concentrations are shown to be related to soil parent material and possibly to pedological and hydrological factors. At Lake Nakuru National Park, plant trace element concentrations vary with plant species and the geochemical conditions that influence uptake are discussed. Impala at Lake Nakuru National Park and black rhino at Solio Wildlife Reserve are shown to have a lower blood copper status than animals from other areas. The trace element status of wildlife is assessed also with respect to critical concentrations used for domestic ruminants. It is suggested that at Lake Nakuru National Park, the low soil copper content and high molybdenum content of some plants contributes to the low copper status of impala and may also influence the nutrition of other species.

    Heavy metal migration in soils and rocks at historical smelting sites (1995)

    Notes: Abstract The vertical migration of metals through soils and rocks was investigated at five historical lead smelting sites ranging in age between 220 and 1900 years. Core samples were taken through metal-contaminated soils and the underlying strata. Concentration profiles of lead and zinc are presented from which values for the distances and rates of migration have been derived. Slag-rich soil horizons contain highly elevated metal concentrations and some contamination of underlying strata has occurred at all sites. However, the amounts of lead and zinc that have migrated from soils and been retained at greater depths are comparatively low. This low metal mobility in contaminated soils is partly attributed to the elevation of soil pH by the presence of calcium and carbonate originating from slag wastes and perhaps gangue minerals. Distances and rates of vertical migration were higher at those sites with soils underlain by sandstone than at those with soils underlain by clay. For sites with the same parent material, metal mobility appears to be increased at lower soil pH. The mean migration rates for lead and zinc reach maxima of 0.75 and 0.46 cm yr−1 respectively in sandstone at Bole A where the elements have moved mean distances of 4.3 and 2.6 m respectively. There is some evidence that metal transport in the sandstone underlying Bole A and Cupola B occurs preferentially along rock fractures. The migration of lead and zinc is attenuated by subsurface clays leading to relatively low mean migration rates which range from 0.03 to 0.31 cm yr−1 with many values typical of migration solely by diffusion. However, enhanced metal migration in clays at Cupola A suggest a preferential transport mechanism possibly in cracks or biopores.

    Notes: Abstract In order to assess the intake of lead and cadmium by consumers of home grown vegetables in urban areas, replicated experimental plots of uniform size, comprising summer and winter crops, were established in 94 gardens and allotments in nine towns and cities in England. The geometric mean lead and cadmium concentrations for the soils (n = 94) were 217 μg g−1 (ranging from 27 to 1,676 μg g−1) and 0.53 μg g−1 (〈0.2–5.9 μg g−1), respectively. Compared with agricultural soils, the garden and allotment soils contained elevated levels of lead but not cadmium. Lead concentrations in the vegetables ranged from 〈0.25 μg g−1 to 16.7 μg g−1 dry weight and cadmium concentrations ranged from 〈0.025 μg g−1 to 10.4 μg g−1 dry weight. Lead concentrations were higher than reported “background” levels, although 〈1% exceeded the statutory limit for saleable food in the UK (1 μg g−1 fresh weight). Cadmium concentrations were generally similar to “background” levels.

    Seasonal and species variation in the content of cadmium and associated metals in pasture plants at Shipham (1982)

    Notes: Summary Very high Cd and Zn concentrations exist in soils reclaimed from old mine workings at Shipham but little of the metal is transferred into the pasture herbage. The amount of metal in the soil therefore only influences the amount in the aerial part of the plant to a small degree. It would appear to be the plant species which to a large extent governs its metal burden: grasses accumulating the least Cd and members of the Compositae the most. Within this species variation exists a change in metal content that corresponds to the time of year, setal levels in plants peaking in the winter between January and March. This increase in the metal content of the shoot reflects the redistribution of metal previously bound within the root. The movement of Pb may be associated with changes in the phosphate status of the plant. In grasses it would appear that the root possesses the highest metal burden, and forHolcus lanatus, tolerance to both Cd and Zn has been established. The ammonium-acetate and DTPA-extractable Zn/Cd ratio in soils corresponds closely to that found in the roots of both ryegrass and Yorkshire fog. A much higher ratio was observed in the shoots of these plants.

    Sources and pathways of environmental lead to children in a Derbyshire mining village (1991)

    Notes: Abstract Garden soil and housedust samples, from households in a Derbyshire village closely associated with historic lead mining, have highly elevated lead levels. Handwipe samples from children also have relatively high lead concentrations suggesting that elevated levels of lead are transferred to the child by the soil-dust-hand-mouth pathway. However, this is not reflected in their blood lead concentrations which are within normal UK ranges and less than predicted by some lead exposure models. SEM analysis of soil grains has revealed that many are composed of pyromorphite [Pb5(PO4)3Cl], a stable soil-lead mineral. This mineral is formed from the weathering of galena [PbS] but it is not clear to what extent weathering has occurred in the soil. Pyromorphite has an extremely low solubility which may contribute to a low human bioavailability of lead in these soils, resulting in the lower than expected blood lead concentrations.

    Environmental Impacts of a Secondary Lead Smelter in Landskrona, Southern Sweden (1999)

    Notes: Abstract Scandinavia has one secondary lead smelter that recycles lead from approximately 85% of used car batteries in Scandinavia and which has been active since the 1940s. The smelter, situated in Landskrona, has undergone a comprehensive clean up programme during the last decade, during which time production has doubled, while at the same time discharges of dust and lead to the atmosphere have decreased. Top and depth soil samples were taken on a 0.5 km × 0.5 Km grid throughout the city of Landskrona, which covers an area of approximately 15 km2. Samples were analysed by ICP‐AES for a number of elements including Pb, Zn, Cu, Cd, As, Sb and Hg. Road dust samples from selected sites were collected and similarly analysed. Blood samples were taken from 37 volunteer schoolchildren (aged 8–11) from two schools in Landskrona. House dust samples were taken from each child's home. Soil samples were taken from homes which had gardens, public and school play areas. Elevated heavy metal concentrations were found in close proximity to the secondary lead smelter, and this soil enrichment influences the whole of the town, modified to some extent by the prevailing wind. The smelter does not influence the soil lead concentration at distances greater than 3.5 km, where the soil reflects the background value for the area. Road dust samples also show decreases in lead concentrations with distance from the smelter. The average level of lead in house dust was considerably lower than that found in Birmingham, UK. Blood lead levels in the child population ranged from 1.5–5.1 μg dl−1, with a mean of 3.05 μg dl−1, showing a distinct decrease from those measured in 1978–82. No significant difference in blood lead concentrations with distance of the home from the smelter, nor between attenders at the two schools was revealed in the limited number of children studied.

    Notes: Abstract Nitrogen fixation by free-living non-symbiotic bacteria has been qualitatively estimated in several surface soils and mine wastes from mineralised areas in Derbyshire and Cornwall, using a technique based on acetylene reduction. Fresh samples contaminated with varying amounts of one or more of the metals lead, zinc, cadmium and copper, together with appropriate controls, showed no ability to reduce acetylene, indicating an absence of nitrogen fixation. Addition of activeAzotobacter chroococcum resulted in acetylene reduction in the majority but not all of the samples. The effects of varying concentrations of lead, zinc, cadmium and copper on the growth ofAzotobacter chroococcum andBeijerinckia lactogenes were tested in laboratory culture.
