Algal species that produce toxin that can have negative effects on human and environmental health. The effects of HABs on human health can range from gastrointestinal effects to death.

Chemicals used to control weeds and other plants not desired in yards. Atrazine and 2,4-D are widely used herbicides. Herbicides affect the photosynthesis process in plants.

Chemicals used to control insects (mosquitoes, ants, beetles, etc.). Chlorpyrifos is a common insecticide.
