Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. [1] Bioaccumulation occurs when an organism absorbs a substance faster than it can be lost or eliminated by catabolism and excretion.

2024年3月2日 · Bioaccumulation is a phenomenon where the accumulation rate of a substance in an organism surpasses its breakdown (metabolization) or elimination rate, resulting in a gradual increase in the substance within the organism’s body.

Bioaccumulation is a process where contaminants are transported through cellular walls and membranes. The contaminants are bound inside the cells, and this mechanism encompasses several processes, including intracellular accumulation, oxidation, or reduction reactions.

2023年9月29日 · Bioaccumulation is a biological process by which organisms, often at the lower end of the food chain, accumulate certain substances or chemicals at a rate greater than they are metabolically able to excrete.

2024年9月27日 · Bioaccumulation & Biomagnification. Bioaccumulation is the build-up of persistent or non-biodegradable pollutants within an organism or trophic level because they cannot be broken down. This means that organisms at higher trophic levels (such as top predators) may accumulate higher concentrations of pollutants than those at lower trophic levels

Bioaccumulation is the process by which certain substances, like toxins or chemicals, build up in the tissues of living organisms over time. This happens when an organism absorbs these substances faster than it can break them down or eliminate them.

Bioaccumulation is characterized as the net accumulation of all contaminant sources in or on an organism, including water, air, and diet. Bioaccumulation is distinguished as an increase in the concentration of pollutants in aquatic organisms after absorption from the ambient environment.
