ecophysiology and pollution Flashcards
what are 2 ways EDC’s can bind to hormone receptors
agonist - activation of receptor
antagonist - prevent activation of receptor
which ways can an endocrine disrupting chemical work
direct binding to hormone receptor
non-receptor mediated pathways
what are 3 ways EDC’s can act in non-receptor mediated pathways
modify synthesis or metabolism of hormones
modify number of hormone receptors
bind to or modify number of transport proteins in the blood
how can oestrogens get in to water
if contraceptive pill is disposed of in water works
what is the negative implication associated with Biphenol A in plastics
can induce oestrogen response in aquatic life
what effects do anti-androgens bring about
de-masculinisation effects
what 2 ways can anti-androgens get in to water works
from plastics - especially rubber ducks
in limuron pesticide
why is there more evidence for the effects of pollutants in aquatic life
permeable skin so are more sensitive to environmental chemicals
