Which statement is true regarding pollutants with long residence times?

Pollutants with long residence times refer to substances that remain in the environment for extended periods before being broken down or removed. These pollutants pose a significant risk because their prolonged presence can lead to accumulative effects on ecosystems and human health.

Because they do not dissipate quickly, they can build up in the soil, water, and air, leading to increased concentrations that have the potential to cause greater harm to living organisms over time. As they linger, they can interact with various environmental processes, affect biodiversity, and contribute to chronic health conditions in humans.

In contrast, pollutants with short residence times may have more immediate but transient impacts, which generally allows ecosystems and human populations to recover more quickly. Thus, the statement that these long-term pollutants contribute more significantly to environmental issues highlights their persistent nature and lasting effects.
