Pollution of potentially toxic metals in urban road dust in Dushanbe (Tajikistan) [PDF]

E3S Web of Conferences, 2019
Heavy metal contamination in the road dust due to traffic in the capital city of Tajikistan was investigated. Concentrations of potentially toxic elements (Ba, Cu, Cd, Co, Cr, Pb, Ni, Zn and As) in particle size of 63 μm were analyzed.

Heavy Metals Contamination of Road-Deposited Sediments [PDF]

American Journal of Applied Sciences, 2010
Problem statement: Impact of anthropogenic activities on man and his environment as a result of the growing rate of urbanization in Bida, Nigeria is of a great concern. Street sediments that accumulate along pavements in urban environments have the potential to provide considerable loadings of heavy metals to receiving waters and water bodies ...

Monitoring of Finnish arable land: changes in soil quality between 1987 and 1998 [PDF]

, 2002
This study is part of the long-term monitoring of Finnish arable land and it is based on soil analyses of 705 monitoring sites sampled in 1998. The same sites were sampled twice previously,in 1974 and 1987.

Superconducting Detectors for Super Light Dark Matter [PDF]

, 2015
We propose and study a new class of superconducting detectors which are sensitive to O(meV) electron recoils from dark matter-electron scattering. Such devices could detect dark matter as light as the warm dark matter limit, mX > keV. We compute the rate

Magnetic responses for heavy metal pollution recorded by the sediments from Bohai Sea, Eastern China

iScience, 2022
Summary: The Bohai Sea is facing multidirectional pressure from economic development and pollutant emissions. Magnetic minerals and heavy metal concentrations in the sediments of core M5 from the Bohai Sea were performed.

Environmental effect of heavy metals deposition in arid city [PDF]

Global NEST Journal, 2019
<p>This paper analysis the contents and variation of heavy metals in wet and dry deposition in Changji (Xinjiang, China) revealed their reducing regularity for heavy metals in atmosphere in arid area. Samples (including 84 dry deposition samples and 16 wet deposition samples) were collected from January 2016 to December 2016, and the contents of ...

Background levels of heavy metals in surficial sediments of the Gulf of Lions (NW Mediterranean): An approach based on 133Cs normalization and lead isotope measurements [PDF]

, 2005
This paper presents an attempt to reach natural background levels of heavy metals in surficial sediments of the Gulf of Lions(NW Mediterranean). To correct for the grain-size effect, normalization procedures based on a clay mineral indicator element are ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Transport characteristics of heavy metals in the soil-atmosphere-wheat system in farming areas and development of multiple linear regression predictive model

Scientific Reports
Heavy metal accumulation in agricultural products has become a major concern. Previous studies have focused on the transport of heavy metals from the soil and their accumulation in crops. However, recent studies revealed that wheat leaves, ears, and awns
