New cards

Bioaccumulation

chemical substance or toxin builds up in a single organism over the span of its life in tissues

dont leave urine easily

Often POPs

2
New cards

Biomagnification

chemical substance or toxin that is transferred through a food chain from lower trophic levels to higher trophic. Results in higher concentration in apex predators

Often POPS

3
New cards

Microplastics are how big

Less than 5mm

New cards

Microplastics health impacts

  • Small plastic particles accumulate din every tissued they examined, including deep brain tissue. 

  • Exposure to the plastics led to behavioural changes in mice, similar to dementia in humans

  • Possible that microplastics could decrease a protein that impacts the brain

5
New cards

Minamata Disease (Mercury Food Poisoning)

  • Japan

  • Chisso Corp (local petrochemical & plastics maker) dumped ~27 tons of mercury into Minamata Bay.

  • Mercury bioaccumulation in the tissues of fish & shellfish

  • biomagnification, mercury poisoning occurred in the humans that ingested the contaminated fish & shellfish.

Biomagnification of DDT

Taken in by bottome feeders like zooplankton

7
New cards

Biomagnification of Methyl/mercury

Taken in by Phytoplankton
