    Notes: Abstract A high-precision regional geochemical data base of Jamaica is being developed as a basis for a wide variety of economic and environmental applications. These include pollution studies, resource identification and management, agriculture, land use, and the relationship between geochemistry and the health of crops, animals, and man. The acquisition of analytical data is mainly by instrumental neutron activation analysis using a SLOWPOKE reactor and by energy dispersive X-ray fluorescence. Concentration ranges and means in soil are presented for 31 elements and maps illustrating the distributions of Al, Br, Co, and the γ-ray intensities are presented as examples. Compared with world averages the levels of many heavy metals in Jamaican soils are found to be relatively high and in the main strongly correlated with bauxite occurrences. The high content of bromine in the soils appears to reflect the impact of sea-spray.

    Notes: Abstract A regional survey of Jamaican surface soils has been conducted in which more than 200 samples were collected at a sample density of 1 per 64 km2 across the island and analysed for total concentrations of 31 elements by instrumental neutron activation analysis (INAA), energy dispersive X-ray fluorescence (EDXRF) analysis and atomic absorption spectrophotometry (AAS). The aim of the survey was to begin the construction of a high-precision geochemical database to provide information on elemental levels in soils for application to environmental studies, agriculture, and human and animal health. Results on the regional scale are presented for As, Cd, Cu, Hg and Pb. Although Jamaican surface soils are enriched in several heavy metals compared with world soil means and crustal abundances, lead is of particular importance at this stage because of its occurrence in residential areas. Except for Cu, the distribution maps of these elements are highly correlated with bauxite which in Jamaica is associated with white limestone geology and residualterra rossa soils.

    Elemental concentrations in Jamaican peat (1991)

    Notes: Abstract The peat of the Negril Morass in Western Jamaica was sampled at depths down to 7 m in directions parallel and perpendicular to the seashore, and the samples were analysed for Al, As, B, Br, Ca, Ce, Cl, Co, Cr, Cs, Dy, Eu, Fe, Hf, I, La, Mg, Mn, Na, Sb, Sc, Sm, Sr, Ti, U and V by instrumental neutron activation analysis and by spectrophotometry. The peat is high in ash content, but the concentrations of most elements are below crustal abundances and therefore provide no evidence of nearby mineralisation. The elemental concentrations indicate that no particular environmental hazards are to expected from the use of this peat in electricity generation.

    Notes: Abstract The results of a survey of air particulates at 23 sites across Jamaica for total suspended particulates (TSP), Al, Br, Cl, Na, Pb, and V, by instrumental neutron activation analysis (INAA) and X-ray fluorescence analysis (XRF) are reported. The geometric mean of TSP values, 35 g m-3, is well within the World Health Organisation's standard of 60 g m-3 for TSP, but in areas of high vehicular traffic density the TSP values exceeded this limit. The correlation coefficient between Br and Pb concentrations in the particulates was 0.92 and the Br/Pb ratio of 0.38 compares well with a ratio of 0.39 found in commercial petrol indicating that the exhaust from vehicular traffic is the major source of Pb in atmospheric particulate matter in Jamaica.

    Spatial pattern of arsenic and lead distributions in Jamaican soils (1996)

    Notes: Abstract The spatial patterns of arsenic and lead distribution in Jamaican soils were studied using the Geographical Resources Analysis Support System (GRASS) and data from an island wide soil survey. Arsenic and lead were analysed by instrumental neutron activation analysis (INAA) and energy-dispersive X-ray fluorescence (EDXRF) techniques. The frequency distribution of each element is discussed in relation to major lithological groups. The As-Pb background levels for different areas in Jamaica were estimated.

    Lead in a residential environment in Jamaica (1996)

    Notes: Abstract The background levels of lead in Jamaica in soils and sediments, estimated at 37 mg kg−1, are relatively high compared with world averages. Several areas have values in excess of this due to mineralisation and pollution. One such is the residential Hope Flats/Kintyre area in which levels of lead up to 2.5% are found in the soils and up to 8 μg kg−1 in the water of the nearby Hope River. The blood lead levels of a sample of children were in the range 5.7–57 μg dl−1. The high lead levels suggest a potential health risk, particularly for the children. This can be minimised by programmes which include community education, case management and abatement to reduce the lead exposure.

    Notes: Abstract The Centre for Nuclear Sciences (CNS) uses a raster based geographic information system (GIS), integrated with a relational database to store information on point sampled data, including concentrations of over 50 elements and/or ions in a variety of sample materials. These data are filtered in the GIS to create surface layers and are assigned colours according to percentile ranges allowing visual inspection to be used to identify significant features and trends. The database currently contains raster map layers for soils and geologic features, point site data for water and air, and vector data for roads, rivers and streams. While data are still being added to the database interesting results are already being obtained and a few instances where the GIS was used to assist in the data interpretation are reported.

    Heavy metal pollution in Jamaica 1: Survey of cadmium, lead and zinc concentrations in the Kintyre and Hope Flat districts (1995)

    Notes: Abstract Despite its being highly mineralised, the Hope Mine area has become a residential district. Composite soil samples taken from 91 allotments show values for cadmium: 〈 2–220 mg kg−1, lead: 6–38,000 mg kg−1, and zinc: 66–40,000 mg kg−1. Water samples from adits contain 52–86 μg kg−1 of lead and 〈 1–2 hg kg−1 of cadmium. The soil contents of cadmium and lead in at least two areas suggest that remedial actions should be considered. Blood lead levels for 33 children aged between ten months and seven years are in the range 5.7–57 μg dl−1; haemoglobin levels vary between 9.7 and 12.7 mg dl−1. There is no obvious relationship between Pb and haemoglobin levels. Further geochemical work to define fully the spatial extent of the polluted region and epidemiological studies including intelligence testing to define further the effects of lead on children in this environment would be valuable.

    Notes: Abstract The results of the analysis of approximately 100 soil samples for Na, Mg, Al, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, As, Sb, Ba, La, Sm, Eu, Dy, Lu, Hf, Th, and U by neutron activation analysis, in three soil horizons from four of the main agricultural parishes of Jamaica are presented. While there is some regional variation in the abundances, there are no statistically significant distributions of abundances across the horizons. The results for a few selected elements are compared with abundances in other countries.
