BACKGROUND Metal mining and waste discharge lead to regional heavy metal contamination and attract major concern because of the potential risk to local residents. METHODS This research was conducted to determine lead (Pb), cadmium (Cd), arsenic (As), manganese (Mn), and antimony (Sb) concentrations in soil and brown rice samples from three heavy metal mining areas in Hunan Province, central C...

Lead remains a significant hazard to the health of American children.’3 Virtually all children in the United States are exposed to lead that has been dispersed in air, dust, and soil by the combustion of leaded gasoline. Several hundred thousand children, most of them living in older houses, are at risk of ingesting lead-based paint as well as leadbearing soil and house dust contaminated by the...

The Pb region is characterised by the existence of collective octupole states. Here we populated such states in Pb + Pb deep-inelastic reactions. γ-ray angular distribution measurements were used to infer the octupole character of several E3 transitions. The octupole character of the 2318 keV 17− → 14 in Pb, 2485 keV 19/2− → 13/2 in Pb, 2419 keV 15/2− → 9/2 in Pb and 2465 keV 17/2 → 11/2− in Tl...

BACKGROUND Lead exposure constitutes a major public health concern globally. Relative to developed nations, lead exposure is understudied and poorly addressed in Africa, and there is a dearth of information available to inform lead poisoning prevention strategies, even in high-risk groups such as workers in shooting ranges who are potentially exposed to lead daily. METHODS Two workers at a pr...

The concentration of Cadmium (Cd) and lead (Pb) in different cigarette brands sold and/or produced in Saudi Arabia were determined by atomic absorption spectrometry (AAS). Average levels of Cd and Pb in different cigarette brands in Saudi Arabia were 1.81 and 2.46 μg g1 (dry weight), respectively. The results obtained in this study estimate the average quantity of Cd inhaled from smoking one pa...

The main aim of this work was to study the removal efficiency of Pb from synthetic and industrial wastewaters by using biomass fly ashes. The biomass fly ashes were produced in a biomass boiler of a pulp and paper industry. Three concentrations of Pb(2+) were tested in the synthetic wastewater (1, 10 and 1000 mg Pb/L). Moreover, two different wastewaters were collected in an industrial wastewat...

INTRODUCTION When considering the potential radiological impacts of anthropogenic radionuclides in the environment, it is important to understand the doses incurred by biota by natural activity concentrations of naturally occurring radionuclides. Naturally occurring Po (half-life138 days) and Pb (half-life 22.3 years) are members of the U decay chain. In the marine environment, Po and Pb are pr...

Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in [Formula: see text] collisions at [Formula: see text] = 5.02 and 13 TeV and in [Formula: see text] + Pb collisions at [Formula: see text] = 5.02 TeV, and compared to the results obtained for low-multiplicity [Formula: see text] collisions at [Formula: see text] = 2...
