Lead foreign bodies in joint spaces, often due to projectiles such as bullets, may cause localized arthropathy. There are no reports of joint fracture related to lead arthropathy. Additionally, lead foreign bodes embedded in the joint space may be a source of systemic lead absorption, causing elevated blood lead levels and toxicity to other organs. We present a young adult patient with retained...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...

Measurement of total and trimethyl lead in mammalian tissue is described, using ion exchange/high performance liquid chromatography in tandem with flameless atomic absorption spectrometry for lead-specific detection. All lead forms in whole blood and homogenates of soft tissue--brain, kidney, and liver--were liberated from tissue binding by treatment with dilute (3N) HCl for a period of 18 hr. ...

Violets of the sections Melanium were examined for their colonization by arbuscular mycorrhizal fungi (AMF). Heartsease (Viola tricolor) from several heavy metal soils was AMF-positive at many sites but not at extreme biomes. The zinc violets Viola lutea ssp. westfalica (blue zinc violet) and ssp. calaminaria (yellow zinc violet) were always AMF-positive on heavy metal soils as their natural ha...

An analytical procedure was derived to provide an accurate measurement of low lead (Pb) and cadmium (Cd) concentrations in soil extracts using graphite furnace atomic absorption spectrometry (GFAAS). Based on peak area measurements and with background correction, the use of 2% phosphoric acid as chemical modifier enables the GFAAS to give measurements of Pb and Cd concentration as low as 3 fLg ...

Organic-inorganic methylammonium lead halide perovskites have recently attracted great interest emerging as promising photovoltaic materials with a high 20.8% efficiency, but lead pollution is still a problem that may hinder the development and wide spread of MAPbI3 perovskites. To reduce the use of lead, we investigated the structures, electronic and optical properties of mixed MAGexPb(1-x)I3 ...

Permanent modifiers (Zr, W, Ru, Zr–Ru and Zr–W) thermally deposited on platforms inserted in pyrolytic graphite tubes and Pd 1 Mg(NO3)2 conventional modifier mixture have been employed for the determination of cadmium and lead in dissolved environmental, botanic and biological samples by electrothermal atomic absorption spectrometry (ETAAS). Optimum masses and mass ratios of permanent modifiers...

In this study, the concentrations of some essential (Ca, Cu, Fe, Mg, Mn, Ni, and Zn) and non-essential metals (Cd and Pb) were determined in blood of pregnant women aged between 15 – 45 years and enrolled at the Obafemi Awolowo University Teaching Hospitals Complex, Ile – Ife, Nigeria, for antenatal care. Fifty samples of whole blood were collected from the pregnant women and twenty five sample...
