[no object]
  • (of a substance) become concentrated inside the bodies of living things.

    mercury has bioaccumulated in the fish
    Example sentencesExamples
    • PCBs are ubiquitous in the environment and they bioaccumulate through the food chain due to their high chemical stability and low rate of clearance.
    • When they seep into the water table, and into rivers, lakes, and oceans, PCBs bioaccumulate, moving up the food chain from the phytoplankton to the zooplankton to the fish.
    • Because PCBs bioaccumulate, they are found in large quantities in animals high up the food chain, especially those with lots of body fat.
    • Based upon this information, it is important to note that cyanide does not bioaccumulate in fish.
    • In the Great Lakes ecosystem, PCBs have bioaccumulated in the aquatic food web, especially in predator fish and in the fatty tissues of humans.
    • This potent neurotoxin bioaccumulates in freshwater fish and seafood and is especially dangerous to the developing fetus.
    • It is possible that foods that bioaccumulate are more likely to be affected by the arsenic content in irrigation water.
    • Chemicals bioaccumulate as plants are consumed by animals, which are consumed by humans.
    • When PCBs are consumed, directly or through eating fish, they are not excreted but bioaccumulate in fatty tissue; the EPA continues to rank them among the chemicals most toxic to human health.
    • They are transported by ocean and air currents, and bioaccumulate in the tissues of living organisms.
    • They are fast-acting, effective against a broad spectrum of organisms, and do not bioaccumulate.
    • Heavy metals being discharged into the lake, particularly copper and zinc, can be toxic to fish and other marine life and may bioaccumulate and contaminate seafood collected from the region.

    • These compounds bioaccumulate in lipid-rich tissues of aquatic organisms including marine mammals.

    • Although persistence may or may not pose a problem, if a substance also bioaccumulates then there is special reason to be concerned about possible risks.
    • When birds swallow these fish, toxins are passed on to their tissues, thus bioaccumulating up the food chain.

Derivatives

  • bioaccumulation

  • noun

      Example sentencesExamples

      • Biological processes are primarily biotransformation, biodegradation, and bioaccumulation.
      • The levels of exposure to these agents are generally low and long-lasting, with a possibility of bioaccumulation and biotransformation, putting the integrity of the environment and human health at risk.
      • Use peaked in the United States in 1959 and then gradually declined as concerns were raised about bioaccumulation via the food chain and adverse impacts on fauna - notably fertility and egg shell thinning in birds.
