Journal of Environmental Geochemistry and Health

 

Environmental Geochemistry and Health is the Official Journal of the Society for Environmental Geochemistry and Health.  The journal publishes original research papers, research notes and reviews across the broad field of environmental geochemistry.

  • Environmental geochemistry establishes and explains links between the chemical composition of rocks and minerals and the health of plants, animals and people.
  • Beneficial elements regulate or promote enzymatic and hormonal activity, whereas other elements may be toxic.
  • Bedrock geochemistry controls the composition of soil and hence that of water and vegetation.
  • Pollution arising from the extraction and use of mineral resources distorts natural geochemical systems.
  • Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically.
  • Associated epidemiological studies reveal the possibility of links between the geochemical environment and disease.
  • Experimental research illuminates the nature or consequences of natural geochemical processes.

High quality research papers or reviews dealing with any aspect of environmental geochemistry are welcomed.  Submission of papers which directly link health and the environment are particularly encouraged.  Papers may be theoretical, interpretative or experimental.  Authors shoud refer to  www.springer.com/10653 for more information and authors' instructions.

  • Cadmium contamination of soil and crops is affected by intercropping and rotation systems in the lower reaches of the Minjiang River in south-western China 2015-09-01

    Abstract

    Cadmium (Cd) accumulation and pollution in arable soils are particularly serious in the lower reaches of the Minjiang River in southwest of China. In this study, the remediation efficiency of Cd contamination in arable soils, the distribution pattern of Cd concentration in crops, and the food safety to humans of three typical cropping systems (S1: maize + sweet potato—Chinese cabbage, S2: maize + ginger—stem mustard, and S3: rice) were investigated and evaluated. After 1-year rotation, the percentage of Cd extracted by crops from the plough soil layer was observed in three system fields with the trend of S1 (2.30 %) > S2 (1.16 %) > S3 (0.21 %) and Cd extraction amount in crops was maximum in sweet potato, then in maize. The same kind of crop had the same pattern of Cd distribution in organs, and the edible parts generally accumulated less Cd amount than the inedible parts. Further, the grain crops were found to possibly be suitable one for using as phytoaccumulators of Cd contamination for farmlands. Direct consumption of these crops from the three systems would pose a high health risk to local inhabitants since it would result in the monthly intake of Cd (247 μg kg−1 body weight) being nearly 10 times higher than the recommended tolerable monthly intake (RTMI) (25 μg kg−1 body weight), resulting mainly from the consumption of vegetables rather than the grains, which would be potentially reduced by these foods being consumed by livestock firstly.

  • Current status of arsenic exposure and social implication in the Mekong River basin of Cambodia 2015-08-23

    Abstract

    To evaluate the current status of arsenic exposure in the Mekong River basin of Cambodia, field interview along with urine sample collection was conducted in the arsenic-affected area of Kandal Province, Cambodia. Urine samples were analyzed for total arsenic concentrations by inductively coupled plasma mass spectrometry. As a result, arsenicosis patients (n = 127) had As in urine (UAs) ranging from 3.76 to 373 µg L−1 (mean = 78.7 ± 69.8 µg L−1; median = 60.2 µg L−1). Asymptomatic villagers (n = 108) had UAs ranging from 5.93 to 312 µg L−1 (mean = 73.0 ± 52.2 µg L−1; median = 60.5 µg L−1). About 24.7 % of all participants had UAs greater than 100 µg L−1 which indicated a recent arsenic exposure. A survey found that females and adults were more likely to be diagnosed with skin sign of arsenicosis than males and children, respectively. Education level, age, gender, groundwater drinking period, residence time in the village and amount of water drunk per day may influence the incidence of skin signs of arsenicosis. This study suggests that residents in Kandal study area are currently at risk of arsenic although some mitigation has been implemented. More commitment should be made to address this public health concern in rural Cambodia.

  • Boron and strontium isotope ratios and major/trace elements concentrations in tea leaves at four major tea growing gardens in Taiwan 2015-08-09

    Abstract

    Isotopic compositions of B and Sr in rocks and sediments can be used as tracers for plant provincial sources. This study aims to test whether tea leaf origin can be discriminated using 10B/11B and Sr isotopic composition data, along with concentrations of major/trace elements, in tea specimens collected from major plantation gardens in Taiwan. The tea leaves were digested by microwave and analyzed by multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS). The data showed significant variations in 87Sr/86Sr ratios (from 0.70482 to 0.71462), which reflect changes in soil, groundwater or irrigation conditions. The most radiogenic tea leaves were found at the Taitung garden and the least radiogenic ones were from the Hualien garden. The δ 11B was found to change appreciably (δ 11B = 0.38–23.73 ‰) which could be due to fertilizers. The maximum δ 11B was also observed in tea samples from the Hualien garden. Principal component analysis combining 87Sr/86Sr, δ 11B and major/trace elements results successfully discriminated different sources of major tea gardens in Taiwan, except the Hualien gardens, and this may be due to rather complicated local geological settings.
