Dungeness crabs are affected by many insecticides. The insecticide carbaryl, also known as Sevin, is particularly toxic to the Dungeness crab. Other toxins include other insecticides and fungicides as well as ammonia. Urban pollutants such as heavy metals, PCB's and hydrocarbons also affect the Dungeness crab. Runoff of pesticides and herbicides affect the Dungeness crab populations as well. Dungeness crabs are not endangered, however, these chemicals can kill or upset the health of Dungeness crab populations.
