Bioremediation consists of using living or-ganisms (usually bacteria,
fungi, actinomycetes, cyanobacteria and to a lesser extent, plants) to
re-duce or eliminate toxic pollutants. These organisms may be naturally
occurring or laboratory cultivated. These organisms either eat up the
contaminants or assimilate within them all harmful compounds from the
surrounding area, thereby, rendering the region virtually
contaminant-free.
Bioremediation is a fairly new technique within the
past ten years that has yielded both remarkable and yet some setback
results. As to advantages, bioremediation is a “natural process”, it
destroys the target chemicals, its’ usually less expensive than other
technologies, and can be used where the problem is located.
Disadvantages of bioremediation include the fact that little is still
known concerning specifics on its effects in areas having multiple
contaminations, it often takes longer than other treatment methods, and
that it requires constant monitoring to ensure effectiveness.
Bioremediation
techniques are currently being used at hazardous waste sites.
Specifically, they are applied to waste sites facilitating the cleanup
of biodegradable contaminants. The ma-jority of environmental hazards in
which Bioreme-diation has proved successful include those of oil
spills, gasoline contaminations, chlorinated solvents and other toxic
chemical leaks.
