TLDR
Results showed that the effect of mineralogy on level of radioactivity should be significant, however, mineralogy effect on heavy metal composition in the sediments should be limited, indicating that other factors such as vicinity of the pollution sources are more important.About:

Heavy metal pollution in surface water and sediment: A preliminary assessment of an urban river in a developing country
Saiful Islam,Saiful Islam,Kawser Ahmed,Mohammad Raknuzzaman,Mohammad Raknuzzaman,Habibullah Al Mamun,Habibullah Al Mamun,Muhammad Kamrul Islam +7 more
TL;DR: In this article, the concentration and chemical fractionation of globally alarming six heavy metals (Cr, Ni, Cu, As, Cd and Pb) were measured in surface water and sediment of an urban river in Bangladesh.
Journal ArticleDOI
Ecological risk assessment and source identification for heavy metals in surface sediment from the Liaohe River protected area, China
TL;DR: The metal speciation analysis indicated that Cd, Pb and Zn were dominated by non-residual fractions and have high mobility and bioavailability, indicating significant anthropogenic sources.
Journal ArticleDOI
Assessment of spatial distribution and potential ecological risk of the heavy metals in relation to granulometric contents of Veeranam lake sediments, India.
TL;DR: The present study recommends that the heavy metal levels are unlikely to cause additional adverse health risks to the aquatic ecosystem associated with this lake.
Journal ArticleDOI
Assessment of metals pollution and health risk in dust from nursery schools in Xi'an, China.
TL;DR: The results indicate no distinct pollution of Mn, Ni, As and Ba in the dust, while Cu, Co and Zn are moderate pollution, Pb is significant pollution, and Cr with large pollution range.

Preliminary assessment of heavy metal contamination in surface sediments from a river in Bangladesh
Md. Saiful Islam,Md. Saiful Islam,Md. Kawser Ahmed,Md. Habibullah-Al-Mamun,Md. Habibullah-Al-Mamun,Md. Fazlul Hoque +5 more
TL;DR: In this article, heavy metals (Cr, Ni, Cu, As, Cd, and Pb) in sediment were investigated from eight different sites of Paira River situated at the southern part of Bangladesh and metals were measured by using inductively coupled plasma mass spectrometer.

sources and effects of ionizing radiation
TL;DR: This annex is aimed at providing a sound basis for conclusions regarding the number of significant radiation accidents that have occurred, the corresponding levels of radiation exposures and numbers of deaths and injuries, and the general trends for various practices, in the context of the Committee's overall evaluations of the levels and effects of exposure to ionizing radiation.

Problems in the assessment of heavy-metal levels in estuaries and the formation of a pollution index
TL;DR: The concept of a baseline is fundamental to the formation of a Biological Quality Index and Pollution Load Index, and a formula for such an index is suggested and tested at a preliminary level against published data for an English and a European estuary as discussed by the authors.

Elemental mass-balance of material carried by major world rivers
Jean-Marie Martin,Michel Meybeck +1 more
TL;DR: In this paper, an estimate of average river particulate matter (RPM) composition was based on analyses of more than 40 elements in the Amazon, Congo, Ganges, Magdalena, Mekong, Parana and Orinoco rivers, covering the whole spectrum of morphoclimatic features.

Trace metal distribution in sediments of the Pearl River Estuary and the surrounding coastal area, South China.
TL;DR: The similar Pb isotopic signatures of the sediments offered strong evidence that the PRE was a major source of trace metals to the adjacent coastal area, and slightly lower Pb/Pb ratios in the coastal sediments may indicate other inputs of Pb in addition to the PRE sources, including the inputs from Hong Kong and other parts of the region.
