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.

  • Microplastics in the benthic invertebrates from the coastal waters of Kochi, Southeastern Arabian Sea 2018-08-01

    Abstract

    This study examined microplastic particles present in the benthic invertebrates Sternaspis scutata, Magelona cinta (deposit feeders) and Tellina sp. (suspension feeder) from the surface sediments of off-Kochi, southwest coast of India. The microplastic particles and thread-like fibres detected in these organisms were identified to be polystyrene by using DXR Raman microscope. Examination of the microplastic particle in Sternaspis scutata by epifluorescent microscopy showed fragmentation marks on the surface suggesting that the microplastic particle was degraded/weathered in nature. The study provides preliminary evidence of the presence of microplastics in benthic fauna from the coastal waters of India. However, further studies are required to understand the sources, distribution, fate and toxicity of the different types of microplastics in benthic invertebrates in order to identify any potential threats to higher trophic level organisms.

  • Mercury bioaccumulation in arthropods from typical community habitats in a zinc-smelting area 2018-08-01

    Abstract

    This study assessed the enrichment of mercury in the food web from the different community habitats in a zinc-smelting area of China. We used a nitrogen stable isotope technique to analyze trophic level relationships among arthropods and found that the first trophic level consisted of plants in the different community habitats, the second trophic level consisted of herbivores such as locusts and grasshoppers (primary consumers), and the third trophic level included spiders and mantes (secondary consumers). Mercury enrichment in the primary consumers was not evident, but enrichment in arthropods of the third trophic level was significant. The average of enrichment coefficients in spiders and mantes was greater than 1. The δ15N values indicated that mercury concentrations accumulated from primary producers to top carnivorous arthropods increased. In this zinc-smelting area, the biological amplification of mercury in the food web is significant. It is reasonable to assume that humans, located at the top of the food chain, are exposed to biomagnified levels of mercury.

  • Hydrogeochemical processes identification and groundwater pollution causes analysis in the northern Ordos Cretaceous Basin, China 2018-08-01

    Abstract

    It is necessary to identify the hydrogeochemical processes and analyze the causes of groundwater pollution due to the lack of knowledge about the groundwater chemical characteristics and the endemic diseases caused by groundwater pollution in the northern Ordos Cretaceous Basin. In this paper, groundwater chemical facies were obtained using the piper trilinear diagram based on the analysis of 190 samples. The hydrogeochemical processes were identified using ionic ratio coefficient, such as leaching, evaporation and condensation. The causes and sources of groundwater pollution were analyzed by correspondence analysis, and the spatial distribution and enrichment reasons of fluoride ion were analyzed considering the endemic fluorosis emphatically. The results show that leaching, evaporation and condensation, mixing, and anthropogenic activities all had significant impact on hydrogeochemical processes in the study area. However, cation exchange and adsorption effects were strong in the S2 and S3 groundwater flow systems, but weak in S1. Groundwater is mainly polluted by Mn and CODMn in the study area. The landfill leachate, domestic sewage, and other organic pollutants, excessive use of pesticides and fertilizers in agriculture, and pyrite oxidation from long-term and large-scale exploitation of coal are the sources of groundwater pollution. The S1 has the highest degree of groundwater pollution, followed by S2 and S3. High concentration of fluoride ion is mainly distributed in the north and west of study area. Evaporation and condensation and groundwater chemistry component are the most important causes of fluoride ion enrichment. The results obtained in this study will be useful for understanding the groundwater quality for effective management and utilization of groundwater resources and assurance of drinking water safety.
