The document discusses hydrocarbons, which are compounds composed of carbon and hydrogen found abundantly in nature. They may be found as liquids like oil or gases like natural gas in geological formations. These fossil fuels and their byproducts are economically important but also cause serious pollution problems through contamination of groundwater, soils, marine life, and atmospheric emissions of gases like carbon dioxide during refining.

2. What are hydrocarbons?
Hydrocarbons are compounds of great
abundance in nature and are composed of
carbon and hydrogen atoms, the first
structural feature of a frame which is joined by
hydrogen atoms. Forming the basic skeleton of
the organic molecules and therefore are also
known as organic compounds.

3. How do we find them?
These compounds may be found in geological
formations, both liquid (commonly known
with the name of oil) as a gas (natural gas).
Thus, these oils provide an economic activity of
prime importance worldwide, as they
constitute the major fossil fuels, as well as raw
material for all types of plastics, waxes and
lubricants.

4. According to their shapes (petroleum and
petroleum products), are assigned a certain
economic value. But we must add that these
are responsible for serious pollution problems
in the natural environment, level surface and
even affect large groundwater reserves.

5. Why affect the environment?
The processes are performed on hydrocarbons
for fuels, produce various wastes, which are
the various phases making up the hydrocarbon
reagents are added to acquire each.
These processes are in some way toxic
substances, which are polluting the
environment.

6. Where pollute?
When the hydrocarbon feedstock is in the
nature reserves, usually these affect the
groundwater and contaminate water that are
close to the nuclei of hydrocarbons, and also
directly affect the lands where they rest.

7. Where pollute?
When hydrocarbon cores are in the depths of
the seas, usually at the time of extraction and
transportation, these substances directly
contaminate the marine flora and
fauna, completely destroying all these forms of
life.

8. What is removed in the atmosphere?
At the time of refining for hydrocarbon fuels,
they generate different emission of harmful
gases into the environment and the
atmosphere, such as carbon dioxide and
carbon monoxide. This means that in most
cases it emanates CO2.
