Pros and Cons of Oil Spill Dispersants Powered By Docstoc
					Oil spills cause a lot of harm to the underwater communities affected by
the oil. The utilization of oil spill dispersants is sometimes
controversial because of misunderstanding about the principle of
dispersing oil and the lack of knowledge of the limitations of
alternatives response techniques. These dispersants are the chemical
products especially designed for marine clean up. They are exclusively
developed to deal with problems associated with marine related oil spills
and the professional clean-up operations that follow the spill. The
advanced marine technology has made it easy to tackle the marine oil
spill problems with the help of advanced oil spill dispersants.The main
purpose of oil spill dispersants is to remove the spilled oil from the
surface of the sea and transfer it into the water column where it is
rapidly diluted to below harmful concentrations and is then degraded. The
dispersants reduces the damage caused by floating oil to some resources
like the sea birds, and minimizes the damage that could be done to
susceptible coastline by spraying the dispersants on the oil before it
reaches the shore. However, the use of the dispersants has the potential
to present a small risk of temporary and local exposure to dispersed oil
for some marine organisms.The oil spill dispersants do not function to
remove oil from the water. Instead, they break down great oil areas into
much lesser pieces that make it simpler for all the sea creatures to deal
with it. The down side is that dispersants also facilitates the spreading
of the spilled oil more extensively into the atmosphere. While the center
of everyone's attention is to do everything possible to prevent the oil
from reaching the shoreline, often it is often overlooked that there is a
large effect on sea floor organisms caused by the oil. These days, robots
are being used undersea to spray the oil-spill dispersants directly on
the oil since it spreads on the ocean floor.Using oil-spill dispersants
is a controversial topic, as many people feel that they add to the harms
caused by the pollution. However, there are other groups of people who
support its use because it is the most quick and effectual means of
reducing the harm that is likely to be caused by the spill. All the
evidence that has been gathered during thirty years of research indicates
that there is only small risk to marine life when the dispersants are
used, when compared to the direct effects of the spill. It has been
scientifically proven that the utilization of dispersants can be an
effective oil-spill response method and there is little likelihood of
oil-spill dispersants causing negative effects unless they are used in
shallow water or very close to particularly sensitive species.Even in
cases when oil spill dispersants might cause negative effects, the
positive benefit obtained by their use might outweigh this to produce a
Net Environmental Benefit. Nevertheless, any use of dispersants must be
carefully planned and explained to all those who might be affected by an
oil spill.
