Lichens and Bromeliads as Bioindicators of Heavy Metal Deposition in Ecuador
Diversity, 2019 We evaluated heavy metal deposition in Parmotrema arnoldii and Tillandsia usneoides in response to air pollution in Loja city, Ecuador. We assessed heavy metal (cadmium, copper, manganese, lead and zinc) content in these organisms at nine study sites ...

The importance of Enrichment Factor (EF) and Geoaccumulation Index (Igeo) to evaluate the soil contamination [PDF]
, 2016 Heavy metals are natural constituents of soils and their concentration varies depending on parental materials. In the last years, the content of heavy metal in soils has increased due to human activities as: distribution of fertilizers, pesticides ...

Microscopic and chemical studies of metal particulates in tree bark and attic dust : evidence for historical atmospheric smelter emissions, Humberside, UK. [PDF]
, 2006 Tree barks and attic dusts were examined as historical archives of smelter emissions, with the aim of elucidating the pathways of pollution associated with a plume of Sn and Pb contamination in top soils, found close to the former Capper Pass smelter ...

Atmospheric Deposition Of Heavy Metals In Toronto [PDF]
, 2021 Atmospheric deposition rates of heavy metals (As, Cd, Co, Cu, Hg, Mn, Ni, Pb, and Zn) were determined from July 2009−December 2010 in downtown Toronto. Atmospheric deposition samples were collected using samplers with plastic, glass and water surfaces from two rooftops (15 m and 59 m above ground) in the city core of Toronto.

Heavy metal deposition on plants in relation to immission and bulk precipitation.
Silva Fennica, 1981 Monitoring of heavy metal accumulation in plants has been used to reflect the deposition of heavy metals in terrestrial ecosystems. In some cases, the accumulation rates in plants are linearly correlated to deposition measured as bulk precipitation ...
