TLDR
In this article, the concentration of heavy metals and natural radionuclides in soil around a major coal-fired power plant of Xi'an, China were determined by using XRF and gamma ray spectrometry, respectively.Abstract:
Concentrations of heavy metals and natural radionuclides in soil around a major coal-fired power plant of Xi’an, China were determined by using XRF and gamma ray spectrometry, respectively. The measured results of heavy metals show that the mean concentrations of Cu, Pb, Zn, Co and Cr in the studied soil samples are higher than their corresponding background values in Shaanxi soil, while the mean concentrations of Mn, Ni and V are close to the corresponding background values. The calculated results of pollution load index of heavy metals indicate that the studied soils presented heavy metal contamination. The concentrations of 226Ra, 232Th and 40K in the studied soil samples range from 27.6 to 48.8, 44.4 to 61.4 and 640.2 to 992.2 Bq kg−1 with an average of 36.1, 51.1 and 733.9 Bq kg−1, respectively, which are slightly higher than the average of Shaanxi soil. The air absorbed dose rate and the annual effective dose equivalent received by the local residents due to the natural radionuclides in soil are slightly higher than the mean values of Shaanxi. Coal combustion for energy production has affected the natural radioactivity level and heavy metals (Cu, Pb, Zn, Co and Cr) concentrations of soil around the coal-fired power plant.read more

Heavy metal contamination in soils around the Tunçbilek Thermal Power Plant (Kütahya, Turkey)
TL;DR: The surface soils around TTPP are contaminated by As, Hg, and Ni from uncontaminated to extremely contaminated, and Geoaccumulation index (Igeo) and enrichment factor (EF) have been calculated in order to evaluate heavy metal pollution in the soils.

TL;DR: The present work has shown that the radioactivity levels of some of the materials can be reduced through the removal of fines by sieving, as the fines seem to contain a higher concentration of radioactive nuclides.

Heavy metal pollution of coal mine-affected agricultural soils in the northern part of Bangladesh
TL;DR: Multivariate statistical analyses, principal component and cluster analyses, suggest that Mn, Zn, Pb and Ti are derived from anthropogenic sources, particularly coal mining activities, and the extreme proximal and distal parts are heavily contaminated with maximum heavy metals.
