In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?
Atmospheric Pollution
In the atmosphere, the existence of large quantities of undesirable substances that could cause several health issues to living organisms and humans is atmospheric pollution. Air pollution is otherwise known to be atmospheric pollution. The presence of undesirable materials would also destruct the natural environment such as a change in climate, degradation of habitat, or depletion of ozone. Air pollution is generated by the natural processes and activities of humans.
Smokestack Scrubbers
Once we believe in the environment and remember the pollution-producing facets of it, we will consider the smoke-stacks scrubber to be a number of the worst offenders. Although this is often legally correct, smoke-stack scrubbers often have a big function in terms of keeping ground-level air pollutants- safe to breathe and assisting within the management of emissions.
