Emerging Contaminants Quiz

What are Emerging Contaminants (ECs)?

• New chemical compounds recently discovered

• Previously unregulated contaminants now gaining attention

• Only naturally occurring contaminants

• Contaminants that have been removed from regulations

Which of the following is NOT a common source of ECs?

• Household wastewater

• Agricultural runoff

• Industrial discharge

• Ozone layer depletion

Which category of ECs includes antibiotics and hormones?

• Per- and Polyfluoroalkyl Substances (PFAS)

• Pharmaceuticals and Personal Care Products (PPCPs)

• Pesticides and Herbicides

• Industrial Chemicals

What environmental risk is associated with ECs?
