What type of pollutants commonly attach to finer sediment particles?

The correct choice highlights that pollutants in general can adhere to finer sediment particles. Fine sediments have a high surface area and can act as a substrate for a variety of pollutants, allowing them to bind and travel through water systems. This process is important because it impacts water quality, as sediments can carry a range of contaminants, including nutrients, organic materials, and various chemicals, which can accumulate in aquatic habitats.

While choices such as heavy metals, pesticides, and gases could also represent specific categories of pollutants that may attach to sediments, they do not encompass the broader range of possible pollutants that fine sediments can absorb. This distinction is crucial for understanding stormwater management and pollutant transport, as it emphasizes the general capacity of sediments to influence water quality through numerous types of contaminants.
