Which of the following best describes the key difference between non-absorbable and absorbed pollutants?
Which of the following best describes the key difference between non-absorbable and absorbed pollutants?
- Non-absorbable pollutants primarily affect aquatic ecosystems, while absorbed pollutants affect terrestrial ecosystems.
- Non-absorbable pollutants are always organic, while absorbed pollutants are inorganic.
- Non-absorbable pollutants persist in the environment over long periods, while absorbed pollutants can be broken down naturally. (correct)
- Non-absorbable pollutants are only harmful in small quantities, while absorbed pollutants are harmful at any concentration.
Why does the marginal cost of pollution abatement (MCC) typically increase as more pollution is reduced?
Why does the marginal cost of pollution abatement (MCC) typically increase as more pollution is reduced?
- Because the demand for cleaner technologies decreases as pollution is reduced.
- Because the initial costs of abatement are greater, and those costs are shared across all levels of reduced pollution.
- Because less experienced firms are tasked with abatement.
- Because the easiest and cheapest methods are employed first, requiring more costly methods later. (correct)

Non-Absorbable Pollutants
Pollutants that do not break down in the environment and persist for long periods, causing ongoing damage.
Absorbed Pollutants
Absorbed Pollutants
Pollutants that can be broken down or absorbed by natural processes over time, but can still cause harm if their levels exceed the environment's capacity.

Study Notes
Pollutant Classification
- Pollutants are categorized by how they interact with the environment:
- Non-Absorbable Pollutants: These pollutants persist in the environment, causing long-term damage. They don't break down or assimilate. Examples include heavy metals (mercury, lead) and plastics. These pollutants can remain active for decades or centuries, accumulating in ecosystems and harming organisms. Plastic waste in oceans is a key example – plastic doesn't biodegrade and poses danger to marine life, lasting for centuries.
- Absorbed Pollutants: These pollutants can be broken down or absorbed by natural processes over time. Examples include carbon dioxide (CO2) and nitrous oxide (N2O). While harmful in excess, they can be absorbed by plants or naturally degraded. However, if the level exceeds the ecosystem's capacity, damage can still result, as seen in CO2 accumulation, leading to climate change.
Economic Analysis of Pollution
- Marginal Cost of Pollution Abatement (MCC): Represents the cost of reducing one additional unit of pollution. The MCC curve rises as more pollution is reduced because the easiest/cheapest methods are applied first. As more reduction is needed, more costly solutions become necessary, like carbon capture and storage.
- Marginal Cost of Pollution Damage (MDC): Represents the economic cost of one additional unit of pollution. This includes health impacts, ecosystem harm, and economic losses. The MDC curve increases as pollution increases because the damage worsens (more extreme weather, rising sea levels, etc. with increased carbon emissions).
