Common Chemicals Have a Synergistic Effect

APES-MXCB$R

Which of the following statements BEST describes the synergistic effect of hazardous substances?

A

A common chemical is found to not be a carcinogen at low doses but after years of bioaccumulation, the concentration levels are sufficient to create a cellular environment that promotes cancer.

B

Two food additives have been found to not be carcinogens but when both are present at low doses in a body, they can work together to open up biochemical pathways that promote cancer.

C

The pesticide, aluminum phosphide, is stored in large quantities near inhabited buildings even when less than two pounds scattered around a home killed two children with its toxic vapors in 2010.

D

Arsenic is a soluble, toxic element that can cause cancer. Rice grown in arsenic-contaminated water should be consumed in small amounts to be safe.

E

Benzene is a natural component of petroleum and a known carcinogen. People who live downwind of chemical plants that emit benzene suffer from higher rates of cancer and anemia.
