Assessment of Pollution in the Central Soils of Khuzestan Province with Potentially Toxic Elements (PTEs) and their Origins [PDF]

open access: yesمجله آب و خاک, 2023
Introduction In recent years, soil contamination with potentially toxic elements (PTEs) has become a major problem in most parts of the world. PTEs are naturally generated from the pedogenesis in the soil and are formed mainly by rock weathering ...

Biokonsentrasi Timbal (Pb) pada Hepatopankreas, Insang dan Daging Penaeus merguiensis di Teluk Kelabat Bagian Luar

open access: yesJurnal Kelautan Tropis, 2019
Illegal tin mining or unconventional mining activities produce tailings. Tailings contain dangerous heavy metals one of which is Lead (Pb). The increasing concentration of Pb in the waters will also increase its concentration in the body of the biota ...

Distribution and Source of Pb in Urban Topsoil [PDF]

open access: yesE3S Web of Conferences, 2020
In the process of industrialization and urbanization, human activities have caused more and more heavy metal lead to enter the surface soil, causing harm to the health of residents. Analysis of the status of lead pollution in urban surface soils in China

Correlations and fluctuations in Pb+Pb collisons

open access: yesNuclear Physics B - Proceedings Supplements, 2001
Results on two-particle correlations, deuteron production, event anisotropy and event-by-event fluctuations of p_T/ and K/ pi were obtained by the NA49 experiment in Pb+Pb collisions at 158 A.GeV beam energy. The interpretation of the measurements is discussed in light of the search for deconfinement.

Spatial and temporal variations in Pb concentrations and isotopic composition in road dust, farmland soil and vegetation in proximity to roads since cessation of use of leaded petrol in the UK [PDF]

open access: yes, 2011
Results are presented for a study of spatial distributions and temporal trends in concentrations of lead (Pb) from different sources in soil and vegetation of an arable farm in central Scotland in the decade since the use of leaded petrol was terminated.

Jet fragmentation in p + Pb and Pb + Pb with ATLAS [PDF]

open access: yesNuclear and Particle Physics Proceedings, 2016
Abstract The modification of jets in heavy ion collisions is a central tool to study the properties of QCD matter at high temperature and its interaction with hard probes. Jet production in heavy ion collisions is observed to be suppressed relative to expectations from pp collisions and the measurement of the longitudinal fragmentation functions in

Pollution indices of heavy metals in agricultural soils irrigated with raw sewage (Meshginshahr, Ardabil) [PDF]

open access: yesمدل‌سازی و مدیریت آب و خاک, 2023
Introduction As a great reservoir of nutrients and pollutants, soil plays an important role in health and socio-ecological sustainability. Soil pollution increases as a result of the entry of heavy metals from operations such as agriculture, urbanization,

Toxicity of Pb and of Pb/Cd combination on the springtail Folsomia candida in natural soils: Reproduction, growth and bioaccumulation as indicators [PDF]

open access: yes, 2012
The toxicity of Pb and Cd+Pb was assessed on the Collembola F. candida in two cultivated soils (SV and AU) with low organic matter (OM) content and circumneutral to basic pH, and an acid forested soil (EPC) with high OM content.

Positron emission in PbPb and PbU collisions

open access: yesPhysics Letters B, 1978
Abstract We present quantitative calculations of positron emission dynamically induced in the collision of PbPb and PbU. The results are compared with recent measurements, yielding evidence for new processes characteristic for quantum electrodynamics of strong fields.
