Atmospheric metal pollution monitored by spherical moss bags: a case study of Armadale.
To supplement epidemiological investigations into the mortality from respiratory cancer in the small industrial town of Armadale, central Scotland, spherical moss bags were used to study the deposition of atmospheric metal pollution there during a period of 17 months. High concentrations of most metals were found in areas close to the local steel foundry. High concentrations of some metals were...
متن کاملRestructuring the long-term moss biomonitoring of atmospheric deposition in Germany
The determination of atmospheric deposition in forests can be accomplished using technical sampling devices (bulk samplers, wet only samplers), biomonitors or modelling. In Europe, since 1990 moss sampled every five years at up to 7300 places in up to 36 countries was used as biomonitor. In the moss specimens, heavy metals (HM), nitrogen (N, since 2005) and persistent organic pollutants (POPs, ...
متن کاملThe effect of sampling scheme in the survey of atmospheric deposition of heavy metals in Albania by using moss biomonitoring.
The atmospheric deposition of heavy metals in Albania was investigated by using a carpet-forming moss species (Hypnum cupressiforme) as bioindicator. Sampling was done in the dry seasons of autumn 2010 and summer 2011. Two different sampling schemes are discussed in this paper: a random sampling scheme with 62 sampling sites distributed over the whole territory of Albania and systematic samplin...
متن کاملImages as Bags of Pixels
We propose modeling images and related visual objects as bags of pixels or sets of vectors. For instance, gray scale images are modeled as a collection or bag of (X,Y, I) pixel vectors. This representation implies a permutational invariance over the bag of pixels which is naturally handled by endowing each image with a permutation matrix. Each matrix permits the image to span a manifold of mult...
متن کاملThe Survey of Atmospheric Deposition of Heavy Metal in Albania by Using Moss Biomonitoring and Icp/aes and Naa Technique
The atmospheric deposition of As, Cd, Cu, Cr, Fe, Ni, V, and Zn in Albania was investigated by using the carpet-forming moss species (Hypnum cupressiforme) as bioindicators. This research is a part of the international program (International Cooperative Programme (ICP) Vegetation, UNECE) that had carried out in the most of European countries since 1987, by investigating the impacts of air pollu...
