soil
pollution
Soil pollution
is a current issue. With its direct impact on the environment and consequently
on the health of humans, animals and plants, soil pollution is a real problem
that mobilizes both political powers and citizens.
Let's see
what exactly it looks like, what can be the causes of soil pollution and, to
better understand, some of the most significant examples of pollution.
Soil
pollution: definition
Soil
pollution is a disruptive element for many ecosystems. Its effects are of
several kinds, namely deferred or immediate, but also indirect or direct.
The degree
of severity of soil pollution is variable. It depends on several factors, such
as:
the nature
of the soil, which may affect, depending on the case, the diffusion of metals;
the risks of
transmission of pathogenic elements following the transport of land;
the level of
degradability of each interfering / polluting element;
the very
capacity of the pollutant to impact in any way the functioning of the biosphere
or an ecosystem.
Good to
know: when the origin of soil pollution is determined, this may lead to the
creation of a specific fund to deal with the problem. A contribution may be
requested from the population group recognized as responsible for this
pollution. This is for example the case of the Superfund created in the United
States.
Soil
pollution: what causes?
Like the
degree of severity of the various pollutions, the causes of soil pollution are
extremely diverse. Pollutions are recorded in a dedicated register after being
mapped. The causes of soil pollution may be related to:
An activity:
it can be industrial or agricultural. But it can also be a war, sports,
leisure, or certain categories of accidents.
A pollutant,
namely:
explosives,
the chemical
elements used in the military field,
pesticides,
tar,
the acids,
hydrocarbons,
chrome,
phthalates,
radionuclides,
mineral
oils,
cyanide,
etc.
Good to
know: some indicators make it possible to determine the presence of soil
pollution. In many cases, for example, the snail can be used to evaluate the
content of pollutants such as pesticides or chromium.
Examples of
soil pollution
All
countries are increasingly taking action against soil pollution, for example by
introducing environmental codes to limit the use of polluting substances and
products. This is the case, for example, with the Grenelle law, which is
strictly followed in the area of town planning in order to avoid the risk of soil pollution.
Individuals
may also have an impact they may not be aware of. Here are some recurring
examples of soil pollution linked to activities that each of us may practice on
a daily basis, whether for private or professional reasons, without always
being aware of their impact on the environment.
use your
car: CO2 emissions;
wash your
car: the products used pour into the groundwater;
participate
in a clay trap: dispersion of lead particles;
Treat your
lawn or golf green: pesticides are used too often, some of which contain
arsenic;
heat and
overheat your home: some heating modes are more polluting than others;
repair
roads: pollution by tar.
Good to
know: this list is not exhaustive. If you want to adopt a 100% responsible
attitude, we invite you to consult with professionals to change certain habits
or use non-polluting products.
