Which contaminants are classified as organic?

Organic contaminants are typically characterized by the presence of carbon in their molecular structure and are often associated with human activities. The correct answer identifies pesticides, herbicides, and synthetic organic chemicals as examples of organic contaminants.

Pesticides and herbicides are chemical substances used to manage pests and weeds in agricultural practices. These compounds are designed to affect living organisms and disrupt biological processes, making them significant in discussions about environmental safety and public health. Synthetic organic chemicals include a wide range of man-made compounds that can be used for various industrial and household applications, many of which may pose risks to water quality and ecosystems when they enter water sources.

Understanding organic contaminants is crucial for water treatment and management because they often require different approaches for removal or degradation compared to inorganic substances or pathogens.
