Talk:Biomagnification

message: This possibility should be included in the article if a meltdown occurs at the Japanese nuclear power facilities at Fukushima located next to the ocean, the pollution could reach alaskan fishing waters due to the ocean currents flowing in a circular pattern.  Far ranging fish such as salmon may also be afflicted.AnimeJanai (talk) 14:21, 15 March 2011 (UTC)

2) Biomagnification
Bioaccumulation
• Bioaccumulation is the gradual accumulation of pollutants, chemicals (chronic poisoning) or other substances in 
an organism. 
• Bioaccumulation occurs when the rate of loss of the substance from the body of the organism through catabolism 
(breakdown of complex molecules in living organisms), or excretion is lower than the rate of accumulation of the 
substance.
• As persistent organic pollutants like DDT are long-lasting, the risk of bioaccumulation is high even if the envi-
ronmental levels of the pollutant are not high.
Biomagnification:-
• Biomagnification refers to progressive bioaccumulation (increase in concentration) at each tropical level with 
the passage of time.
• In order for biomagnification to occur, the pollutant must have:
1. a long biological half-life (long-lived), 
2. must not be soluble in water but must be soluble in fats. E.g., DDT.
• If the pollutant is soluble in water, it will be excreted by the organism. 
• Pollutants that dissolve in fats are retained for a long time. 
• Hence it is traditional to measure the amount of pollutants in fatty tissues of organisms such as fish.
• In mammals, milk produced by females is tested for pollutants since the milk has a lot of fat in.

message: Hi! Here are some of the things I'm planning to improve with this article:
- substances that biomagnify has no inline citations, add those or fix in another way
- deal with pop-up at top of the page, make sure there are enough in-line citations
- A lot of the current sources are 15-30 years old- I want to look at current literature and see if anything has changed since then Sterna25 (talk) 15:28, 22 November 2022 (UTC)

message: I have revised the terminology to make it more precise.  As well explained in Toxin toxicologists use the word toxin to refer to toxicants of biological origin, but in lay usage the nouns toxin and even toxic are used to refer to harmful substances of artificial origin. Moreover, biomagnification, and its opposite biodilution, are natural processes which can occur for any substance, not only 
artificial or harmful ones. CharlesHBennett (talk) 14:12, 21 January 2023 (UTC)
thread_title:  more precise terminology regarding biomagnification and nouns toxic and toxin 

message: "A well known example of the harmful effects of DDT biomagnification is the significant decline in North American populations of predatory birds such as bald eagles and peregrine falcons due to DDT caused eggshell thinning in the 1950s."
Does anyone actually still believe this is true?!?!213.31.95.122 (talk) 19:38, 25 August 2023 (UTC)
