#Nanoparticles accumulate quickly in wetland sediment (Phys. org) A Duke university team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting an action they say could indirectly damage the aquatic food chain.
But the researchers warn that based on their previous research the tendency for the nanotubes to accumulate in sediment could indirectly damage the aquatic food chain in the long term
The nanoparticle-pollutant package could then be eaten by sediment-dwelling organisms in a sort of'Trojan horse'effect allowing the adsorbed contaminants to accumulate up the food chain.
She s studying how microbes at the base of the oceanic food chain and global carbon cycle are affected by the seasonal transition from winter to summer.
and organizations across the food chain to share best practices on ways to reduce, recover, and recycle food loss and waste.
and it easily makes its way into the food chain. Yellowfin tuna stocks have seen a 3. 8 percent increase in mercury levels every year
and introduced to the marine food chain the researchers discovered. Using the parasite Toxoplasma gondii as a model they showed how these sticky polymers increase the chance that disease-causing organisms would be picked up by marine snails
The first three are known all pathogens to infect humans through the food chain or via hospital-acquired infections.
The mercury builds up in the food chain, ultimately resulting in toxic fish. According to THE WHO, between 1. 5 and 17 in every thousand children living in selected subsistence fishing populations showed cognitive impacts caused by the consumption of fish containing mercury.
