Lead exposure was assessed in a random cohort of 70 male papier maché workers and compared with 35 age and sex matched controls. Blood-lead levels in workers were significantly higher than in control...Read More
Intraperitoneal administration of lead acetate, lead carbonate, lead chloride, lead nitrate or lead oxide at 0.5 or 6 mg per kg per day on five consecutive days was found to produce diverging effects ...Read More
Determination of PbO2 formation kinetics from the chlorination of Pb(II) carbonate solids via direct PbO2 measurement.
Lead dioxide (PbO(2)), a new form of lead corrosion product discovered in the distribution system, is formed via the chlorination of Pb(II) solids and plays an important role in regulating lead concen...Read More
Chemical transformations of lead compounds under humid conditions: implications for bioaccessibility.
This short communication documents chemical transformations caused by weathering of two Pb compounds that commonly occur in house dust. Chamber experiments were designed to simulate humid indoor envir...Read More
Heavy-metal remediation by a fungus as a means of production of lead and cadmium carbonate crystals.
We show here that reaction of the fungus, Fusarium oxysporum, with the aqueous heavy-metal ions Pb2+ and Cd2+ results in the one-step formation of the corresponding metal carbonates. The metal carbona...Read More
Successful application of lead isotopes in source apportionment, legal proceedings, remediation and monitoring.
In late 2006, the seaside community in Esperance Western Australia was alerted to thousands of native bird species dying. The source of the lead (Pb) was determined by Pb isotopes to derive from the h...Read More
Windblown lead carbonate as the main source of lead in blood of children from a seaside community: an example of local birds as "canaries in the mine".
In late 2006, the seaside community in Esperance, Western Australia, was alerted to thousands of native bird species dying. The source of the lead was thought to derive from the handling of Pb carbona...Read More
Investigation of the kinetics and mechanisms of the oxidation of cerussite and hydrocerussite by chlorine.
Reactions of representative lead (II) solid phases (hydrocerussite, cerussite) with chlorine were examined in this study. Chlorine consumption profiles for these solids exhibited a lag phase, during w...Read More
Poststaining ultrathin sections on grids is an essential process in preparing specimens for examination using transmission electron microscopy. This process commonly consists of staining in aqueous so...Read More
Old Masters' lead white pigments: investigations of paintings from the 16th to the 17th century using high precision lead isotope abundance ratios.
White lead (2PbCO(3).Pb(OH)(2)), a common component in 17c. artists' painting materials, was singled out to investigate the potential of lead isotope abundance ratios in the field of authenticati...Read More
X-ray absorption fine structure combined with fluorescence spectrometry for monitoring trace amounts of lead adsorption in the environmental conditions.
The local structure of trace amounts of lead in an adsorbent matrix that contains a high concentration of iron and magnesium (Mg6Fe2(OH)16(CO3) x 3H2O) was successfully monitored by means of X-ray abs...Read More
To determine if additive or synergistic toxic effects would occur, adult male rats were exposed orally to lead carbonate (2,000 mg/kg) for 9 days before trichloroethylene (TCE), 2,000 mg/kg, was given...Read More
[Investigation of the sequestration of CO2 and carbonation process for the stabilization of MSW fly ash].
The sequestration of CO2 and carbonation process for the stabilization of fresh fly ash from municipal solid waste (MSW) incinerator were investigated. The purpose of this paper is to evaluate the inf...Read More
Phosphate-induced lead immobilization from different lead minerals in soils under varying pH conditions
This study investigated phosphate-induced lead immobilization from different Pb minerals in soils under varying pHs. Four soils were used, including one Pb-contaminated soil (NC-Soil) and three soils ...Read More
Cobalt(II) carbonate, CoCO"3.4H"2O and lead(II) carbonate, PbCO"3.2H"2O were synthesis by a new simple method during the reaction of aqueous solutions of CoX"2 (X = Cl^-, NO...Read More
Is the OECD acute worm toxicity test environmentally relevant? The effect of mineral form on calculated lead toxicity.
In a series of experiments the toxicity of lead to worms in soil was determined following the draft OECD earthworm reproduction toxicity protocol except that lead was added as solid lead nitrate, carb...Read More
