Coastal pollution in Cuba

Coastal pollution in Cuba
Science and Technology
02 / 09 / 2012

Toxic wastes and pollutants that are generated by different processes in
terrestrial areas are dumped into the sea. Specifically in Cuba, its
geographical costs are the main reservoir and therefore the most damaged
area.
Such a feature-explanatory that usually infectious substances are
organic-biodegradable, due to being the major component of urban and
industrial waste liquids.
Although there is another variety of impurity materials, including
potentially toxic chemicals, the truth is that make up the bulk of the
landings.
A national inventory of corrupt means indicated that 40 percent of them
had no treatment systems for liquid waste, excluding the absence of
sewage in small coastal settlements.
The fact is that in open areas, although they receive the noxious
barrage from land, including sewage, discharges go directly to the sea
and this is responsible for dilution and transport.
For this reason, infection levels are not elevated, except in the
estuarine zone near the mouth of rivers, where avalanches create a
continuous area, mainly as a sort of pen, which possess a high degree of
organic pollution mainly fecal origin.
However, in the bays the loads generated systematically assimilate waste
accumulation, due to poor tidal exchange compared to the volume received
directly or through the rivers that flow into them.
Also influenced by their own geographical features that are mostly
closed bays, with a narrow channel of communication.
In some of them, may be high rates of contamination by organic and
inorganic chemical compounds, with a toxic nature.
These ranges of concentrations are in the bays of Havana and Cienfuegos
Nuevitas, considered the most contaminated by metals.
The same applies to the one in Havana, Cienfuegos, and Mariel, but in
this case hydrocarbon anthropic origin or caused by human activity.
A particular case is that of Levisa, in the province of Holguin, with a
marked pollution caused by metallic elements associated with open pit
mining.
Other effects on the coastal marine area are related to biodiversity,
including urban planning, which helps determine the spatial organization
and allocation of land uses, appropriate management and protection of
natural resources.
