The soil degradation is a reality, and it has occurring especially as a consequence of human
activity. Mining is an example, which causes a great punctual environmental impact and also
adverse diffuse effects in a less visible way. There is an area in the municipal district of
Adrianópolis (PR), Brazil, where mining had been practiced during almost 60 years, where
several tons of scoria from lead process at open weather, under climatological conditions. A
study developed by São Paulo University in this area detected lead above the standards
determined by the U.S. Center for Disease Control and the Mundial Health Organization in 73
children (40,8% of the total analyzed beings), between 2 and 10 years old. As the soil is the first
element to receive the pollutional amount, this work had as objective to evaluate the soil
mesofauna, which operates as an environmental indicator. An incursion through the water of the
antique mining factory (Plumbum S/A) was primarily done, and the determination of total (HNO3,
HClO4 and HF) and exchangeable contents (BaCl2) of lead were done at several samples.
Based in these results, four collections (on May, September and November of the 2007 and
January 2008), done at five selected places, totalized 20 samples per place using Berleze
funnels (heat extraction). The description of the selected places comes along: 1 ? clay soil, used
as the reference place presenting the highest altitude, coverd by native vegetation (medium
high trees and grassy); 2 ? clay soil covered by grassy (atmospheric pollution influence and high
quantity of waste incorporated to the soil); 3 ? clay soil covered by medium high trees and
grassy (direct influence of the chimney once used at lead process); 4 ? sandy soil covered by
medium high trees, grassy and pterofits (influence of particled material from another chimney);
6 ? sandy soil covered by grassy (next to one of the piles of waste). In a general way, from all the
collections, the preponderant group was Acari. Their percentage in relation to the total population
of each collection was maintained around 55% at place 1 (1283,33 to 13629,13 individuals
m2), 65% at place 2 (586,95 to 1731,00 individuals m2) and 80% at place 5 (437,72 to 3740,55
individuals m2), nevertheless at places 3 and 4 several variations occurred, at place 3 (676,48
to 13.987,27 individuals m2), in September and November, the percentage of Acari doubled
the range of 37% in may. At place 4 (507,36 to 7500,99 individuals m2) the contents declined
from approximately 72% at the three first sampling to 22,08% in January. The population of
Collembola presented under 26% for all the places, being the Arthropleona the most common.
However, the smaller population was found at places 2 and 5, where the Collembola do not
overcome 6% of total population. Another more quantitatively expressive groups were found,
especially, at place 1, which presented the higher biodiversity. In comparison of place 1
(reference), a considerable alteration of the mesofauna population was observed MenosThe soil degradation is a reality, and it has occurring especially as a consequence of human
