Determination of soluble ultra-trace metals and metalloids in rainwater and atmospheric deposition fluxes: A 2-year survey and assessment
(Elsevier, 2013)
The present work investigates the relationships between composition of rainwater and dry deposition fluxes by trace metals and metalloids. A modification in automatic “wet-only” and “dry-only” samplers was applied, which ...

Particle-size distribution of polycyclic aromatic hydrocarbons in urban air in southern Spain
(Springer, 2005)
The size distribution of polycyclic aromatic hydrocarbons (PAH) was determined for airborne particles from a large city with high vehicular traffic. The analytical method was optimised and validated using NIST standard ...

A chemical speciation of trace metals for fine urban particles
(Elsevier, 2002)
The chemical speciation of 11 metals in aerosols has been studied in 12 areas of the city of Seville (Spain). Urban particles were collected with a high-volume sampling system equipped with a cascade impactor, which ...

Optimization of a Sequential Extraction Scheme for Speciation of Metals in Fine Urban Particles
(Taylor & Francis, 2002)
A sequential extraction procedure fractioned in four steps was optimized with the purpose of improving a previous scheme for determining the chemical forms of metals in fine airborne particles. The optimization was tested ...

Trend study and assessment of surface water quality in the Ebro River (Spain)
(Elsevier, 2008)
Thirty-four Physical–chemical and chemical variables were analysed in surface water samples collected every month over a period of 24 years. They were determined from thirteen sampling stations located along the Spanish ...
