Soot in Port Harcourt has been a cause for serious concern of recent. This is suspected to be from activities of those producing illegal fuels (bunker kerosene) at the creeks. I suppose the soot is as a result of them burning a portion of crude oil to generate energy to cook the crude to obtain kerosene etc. In industrial setting this is done in well designed furnaces to control the release of pollutants. But these folks at the creek are using crude method to distill crude oil to obtain crude kerosene, hence you see these pollutants in addition to the loss of lives of the masses from explosion of this their crude kerosene.

Adverse air pollution may be divided into two classes – acute and chronic effects. Acute effects manifest themselves immediately upon short term exposure to air pollutants at high concentrations, and chronic effects become evident only after continuous exposure to low levels of air pollution. The chronic effects are very difficult to demonstrate and are consequently less obvious.

Soot is classified as particulate. It is carbon released from the crude oil molecule due to incomplete combustion. Its effect is acute, as you can see and experience its presence almost immediately. The effect include general physical discomfort, skin irritation, damage to paint and aesthetic of both built and natural environment. Other effect includes upper respiratory tract infection. On the positive side, if you can lay hold on a good quantity of this soot you can use it to produce printer ink, paint, and other products that require carbon as feedstock.

What should be our greatest fear?

That black stuff you see there is a lesser evil compared to several other invisible pollutants you cannot see.

In the midst of that black smoke are hundreds of unseen pollutants – they are colourless. These include volatile organic compounds (VOCs) like benzene and formaldehyde as well as polycyclic aromatic hydrocarbons (PAHs). These unseen pollutants are highly carcinogenic.

How bad can things be?

In future Port Harcourt may turn out to be the cancer headquarters of the world if nothing is done urgently to address this mayhem.

And the right time for action is now.

But cant this sooth of a thing be stopped?
