  • Cadmium and zinc migration in Scots pine stands growing in contaminated areas from Metallurgical Plant emissions
    International Journal of Environmental Science and Technology, 2021
    Co-Authors: G. A. Zaitsev, O. A. Dubrovina, A. Yu. Kulagin, R. I. Shainurov
    Abstract:

    The accumulation of cadmium and zinc in aboveground and belowground organs of Scots pine ( Pinus sylvestris L.) and the metal migration extents in the soil–Plant system were analysed for the stands growing in contaminated areas from Metallurgical Plant emissions. The pine stands of the comparable age (38–45 years old), and a similar structure, selected for research, is grown in the sanitary protection zone of the city of Lipetsk (Lipetsk Region, Russia) in the vicinity of the Metallurgical combine (Novolipetsk Steel). Using atomic absorption spectrometry determined cadmium and zinc content in the soil, fine (

The pine stands of the comparable age (38–45 years old), and a similar structure, selected for research, is grown in the sanitary protection zone of the city of Lipetsk (Lipetsk Region, Russia) in the vicinity of the Metallurgical combine (Novolipetsk Steel). Using atomic absorption spectrometry determined cadmium and zinc content in the soil, fine (< 1 mm) roots, annual shoots, and needles. In the impact zone, the Novolipetsk Steel releases significant contamination of the soil’s surface layers with cadmium and zinc. The present investigation identifies the changes in cadmium and zinc content in the soil that correlated (moderately and strongly) with acidity and humus in the ground. The pine fine roots in the impact zone take in these metals sufficiently, with zinc being absorbed more intensively than cadmium. As against the fine roots, it has been indicated that one-year needles and shoots actively cumulate zinc. The biological accumulation and migration coefficient values show that zinc is actively stored in Scots pine annual needles and shoots.

  • study of worker s exposure to tantalum bearing particles in a mining and Metallurgical Plant
    Environmental Geochemistry and Health, 2018
    Co-Authors: Moore Dias K Da Cunha, K Dalia C Pereira, J R D Guimaraes, C Lima, J E C Nascimento, Rosilda Maria Gomes De Lima, A A Hecht, J C B Fiel
    Abstract:

    The objective of this study was to assess worker exposure to mineral dust particles, and a metabolic model, based on the model adopted by ICRP, was applied to assess human exposure to Ta, and predicted values of Ta concentrations in excreta. The occupational exposure to Th, U, Nb, and Ta-bearing particles during routine tasks to obtain Fe-Nb alloys was estimated using air samplers and excreta samples. Ta concentrations in food samples and in drinking water were also determined. The results support that workers were occupationally exposed to Ta-bearing particles, and also indicate that a source of Ta exposure for both workers and the control group was the ingestion of drinking water containing soluble compounds of Ta. Therefore, some Ta compounds should be considered soluble compounds in gastrointestinal tract. Consequently, the metabolic model based on ICRP metabolic model and/or the transfer factor f1 for Ta should be reviewed and the solubility of Ta compounds in gastrointestinal should be determined.
