Types of Pollutants
- Toxic Substances: Contaminants
such as chlorine, pesticides, herbicides, and heavy metals, which have an
acute effect on the ecosystem, disrupt the entire system and reduce the
system's natural ability to recover.
- Conventional Pollutants: Contaminants
such as organic pollutants (treated wastewater, feedlots), plant nutrients
(nitrate, nitrite, phosphorus), thermal pollution (heated or cooled water),
suspended solids (sedimentation, dredging), which are chronic and cause
deterioration over time.
