Oil Spill dispersants - A Boon or a Bane!

The moment we come across an oil spill, one remedy that strikes our mind is the use of oil spill dispersants

. Though we're aware that these dispersants can help contain an oil spill, most of us don't know its exact working mechanism. We don't even know if they are a boon or bane. If you have the same doubts in your mind, then read on!

Pros:

Here are some advantages of using oil spill dispersants

Oil spill dispersants change the chemical and physical properties of oil so that it mixes better with water.

Oil spill dispersants when used efficiently can prove to be a effective method of oil spill containment.

Cons:

Though using dispersants may seem like a fair idea, it has several drawbacks

First and foremost, once dispersants break down oil in the deep water, the oil gets to the top surface, which is then contained using booms. But, what makes their use not advisable is the fact that they cannot be used near the shore. If used, they might be even toxic than the oil itself. For instance, Corexit, the dispersant being used in the containment of the recent Gulf oil spill is a kerosene-based dispersant and can be considered hazardous. Also, EPA recommends the use of this dispersant only at depths of 75 meters or deeper

Dispersants can be effective only when used within 1 or 2 days after an oil spill, after which natural weathering makes the oil more complex to disperse.

Dispersed oil also stands the risk of entering the food chain as there are chances of the oil being consumed by planktons.

Viscous oil cannot be dispersed effectively using chemical dispersants since the oil may run off into the water even before the solvents can penetrate.

Since chemical oil spill dispersants' cons overweigh pros, you can think of using eco-friendly cleaners, such as Oil Gone Easy S-200, which works using bioremediation technique, to cleanup oil spills.
