Lead gunshot pellet ingestion and tissue lead levels in wild ducks from Argentine hunting hotspots
Lead poisoning in waterfowl due to ingestion of lead pellets is a long recognized worldwide problem but poorly studied in South America, particularly in Argentinean wetlands where duck hunting with lead gunshot is extensive. ...
Brassica napus Growth in Lead-Polluted Soil: Bioaccumulation in Plant Organs at Different Ontogenetic Stages and Lead Fractionation in Soil
Lead is known to be a highly toxic metal; it is often found in soils with the potential to be incorporated by plants. Here, the bioaccumulation of lead by rapeseed (Brassica napus) from a soil with Pb(II) added just before ...
Accumulation of lead and associated metals (Cu and Zn) at different growth stages of soybean crops in lead-contaminated soils: food security and crop quality implications
(Springer Verlag Berlín, 2017-02)
The Pb, Cu and Zn content, the physicochemical parameters in soils (EC, OM%, soil texture and pH) and the metal accumulation of Glycine max plants at different growth stages were evaluated. Topsoil and soybean samples were ...
Piezoelectric and structural properties of bismuth sodium potassium titanate lead-free ceramics for energy harvesting
The development of piezoelectric ceramics with high energy conversion efficiency is of decisive importance for the requirements of the advanced energy harvesting devices toward miniaturization and integration. Lead ...
Comparison of lead contamination among related scavenging birds sharing food sources: a call for caution when using surrogate species
Lead contamination is a global problem affecting a large number of bird species around the world. Among the different avian guilds, vultures and facultative scavengers are particularly threatened by this toxic metal. ...
New Strategy for Corrosion Inhibition Coatings for Lead Heritage Metal Objects
(Pergamon-Elsevier Science Ltd, 2015)
A sensitive spectrophotometric method for lead determination by flow injection analysis with on-line preconcentration
(Elsevier Science, 2004-12)
A new flow injection (FI) system for the determination of Pb(II) at trace level with a preconcentration step and spectrophotometric detection is proposed. It is based on preconcentration of lead ions on chitosan and ...
Lead and life
(Research Signpost, 2010)
Lead is naturally distributed in all ecosystems, but excessive use resulting from urbanization and industrial processes has increased its concentration in the environment. Lead is a persistent pollutant in nature; it cannot ...
Lead exposure in dogs fed game meat and offal from culled invasive species in El Palmar National Park, Argentina
(Springer Heidelberg, 2021-04)
This is the first field study to evaluate lead exposure in dogs fed game meat and offal and, to our knowledge, the first study exploring associations between game consumption and dog health status. We quantified lead ...
