1. : the process by which a compound (such as a pollutant or pesticide) increases its concentration in the tissues of organisms as it travels up the food chain In a process known as Biomagnification, fish accumulate mercury more rapidly than they excrete it, and every fish up the aquatic food chain contains more than the one it just ate.
2. Biomagnification can be defined as the rise or increase in the contaminated substances caused by the intoxicating environment. The contaminants might be heavy metals such as mercury, arsenic, and pesticides such as polychlorinated biphenyls and DDT

3. Bioaccumulation and Biomagnification are two concepts intimately tied to human health and difficult ones to comprehend. There are many chemicals and toxins that can bioaccumulate in organisms and biomagnify through the food web, including DDT, PCBs, mercury, and algal biotoxins.

6. “ Biomagnification (or bioaccumulation) refers to the ability of living organisms to accumulate certain chemicals to a concentration larger than that occurring in their inorganic, non-living environment, or in the case of animals, in the food that they eat.
7. Definition of Biological Magnification Also referred to as “ Biomagnification ” or “ bioamplification, ” biological magnification happens when there is an increase in the number of chemicals and toxins that accumulate through the trophic levels of a food chain.

11. Biomagnification refers to the condition where the chemical concentration in an organism exceeds the concentration of its food when the major exposure route occurs from the organism’s diet.

14. Biomagnification is also known as “ biological accumulation ” refers to the process by which certain toxic substances such as mercury and pesticides find their way into the environment like water bodies and gradually move up the food chain in much higher concentrations.

15. Biomagnification, or biological magnification, is the increasing buildup of toxic substances within organisms that happens at each stage of the food chain.

21. Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain

22. Biomagnification should not be confused with bioaccumulation
Biomagnification, Be, Bioaccumulation
23. While Biomagnification refers to increasing concentration of substances with each successive link in the food chain, bioaccumulation is the increase in the concentration of a particular substance within an organism.
24. Biomagnification is a cumulative increase in the concentrations of a persistent substance (e.g
25. Bioaccumulation and Biomagnification are two different processes that often occur in tandem with one another.Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms, while Biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.
Bioaccumulation, Biomagnification, By, Building
26. Biomagnification, which is the increase in concentration of toxins up the food chain, especially affects you
27. Biomagnification of POPs occurs as they move up the food chain when predators consume prey, ingesting the POPs that have bioaccumulated in each prey item
28. Microplastics compound this problem by adding another more concentrated layer of exposure to the Biomagnification process
29. Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain
30. The process of a buildup of certain chemical substances or toxins at the higher trophic levels of a food chain is termed as Biomagnification

36. Biomagnification • Biomagnification, also known as bioamplification or biological magnification, is the increase in concentration of a substance, such as the pesticide DDT, that occurs in a food chain as a consequence of: • Persistence • Food chain energetics • Low rate of internal degradation/excretion of the substance (often due to water

biomagnification (noun) · biomagnifications (plural noun)
Biomagnification is the process in which toxins are concentrated in an organism as larger animals continue to eat smaller animals.
Biomagnification, also known as bioamplification or biological magnification, is the increasing concentration of a substance, such as a toxic chemical, in the tissues of tolerant organisms at successively higher levels in a food chain.
Biological magnification occurs by increasing the toxicity of poisonous substances as those substances move up the food chain. An example of biological magnification and its dangers is any small fish that eats plankton that has been tainted with mercury.
Biological magnification definition, the increasing concentration of toxic substances within each successive link in the food chain. See more.
