Which substance bioaccumulates in the body?

Explanation:
Bioaccumulation happens when a substance is persistent and lipophilic, so it isn’t easily metabolized or excreted and gradually builds up in the organism’s tissues over time. DDT fits this pattern: it’s highly fat-loving and resists breakdown, so it stores in body fat and remains for long periods, allowing small exposures to accumulate into a substantial body burden and even pass up the food chain. In contrast, ethanol is rapidly metabolized by the liver and cleared from the body, acetaminophen is processed and eliminated (though excessive doses can cause toxicity), and acetone is volatile and quickly excreted. That’s why DDT is the substance that bioaccumulates.
