Modulation of PAH toxicity on freshwater organisms by microparticles
The Why
The PAH phenanthrene affects gammarids´survival and swimming behavior
The microparticles of polyamid and sediment don‘t affect gammarids
The combination of phenanthrene and microparticle lowers the toxicity of phenanthrene
phenanthrene adsorbes to microparticles
modulation is independent of microparticle type
The What
PAHs are ubiquitous POPs
PAHs are known to cause potential negative health effects
PAHs are hydrophobic and therefore bind preferentially to particles
Microparticles are also ubiquitous
Microparticles have increasing surfaces in relation to size
Microparticles are thought to bind and transport chemicals in the environment
