Lead exposure from aluminum cookware in Cameroon.
Blood lead levels have decreased following the removal of lead from gasoline in most of the world. However, numerous recent studies provide evidence that elevated blood lead levels persist in many low and middle-income countries around the world at much higher prevalence than in the more developed countries. One potential source of lead exposure that has not been widely investigated is the leac...
متن کاملRadioactivity Measurements on Glazed Ceramic Surfaces
A variety of commonly available household and industrial ceramic items and some specialty glass materials were assayed by alpha pulse counting and ion chamber voltage measurements for radioactivity concentrations. Identification of radionuclides in some of the items was performed by gamma spectroscopy. The samples included tableware, construction tiles and decorative tiles, figurines, and other...
متن کاملDo Glazed Ceramic Pots in a Mexico-US Border City Still Contain Lead?
In order to identify the presence of lead in glazed ceramic pots in a Mexico-US border city, 41 clay pots were sampled. The pots were purchased in several establishments located in different geographical areas of the city. The presence of lead was determined using LeadCheck Swabs. Most (58.5%) of the pots were from the State of Jalisco and 24.4% were of unknown origin. Only 4 pots did not conta...
متن کاملThe voltammetric behaviour of lead at a microband screen-printed carbon electrode and its determination in acetate leachates from glazed ceramic plates.
Microband screen-printed carbon electrodes (μBSPCEs) without further modification have been investigated as disposable sensors for the measurement of lead in acetate leachates from ceramic glazed plates. Cyclic voltammetry was employed to elucidate the electrochemical behaviour of Pb(2+) at these electrodes in a variety of supporting electrolytes. The anodic peaks obtained on the reverse scans,...
