Isotopes of many elements have been used in terrestrial, atmospheric, and aqueous environmental studies, providing powerful tracers and rate monitors. Short-lived nuclides that can be used to measure time are continuously produced from nuclear reactions involving cosmic rays, both within the atmosphere and exposed surfaces, and from decay of long-lived isotopes. Nuclear activities have produced...

Goals and Scope The aim of the speciation symposia is to facilitate interdisciplinary and intersector discussion about all aspects of elements requiring an understanding of speciation, including" analytical science, geochemistry, biochemistry, clinical chemistry, environmental science, toxicology, essentiality and nutrition, medical uses, environmental and occupational health, and regulatory as...

An urban survey of Lisbon, the largest city in Portugal, was carried out to investigate its environmental burden, emphasizing metallic elements and their public health impacts. This paper examines the geochemistry of lead (Pb) and its influence on human health data. A total of 51 soil samples were collected from urban recreational areas used by children to play outdoors. The semi-quantitative a...
