| effects of zn and ti nanoparticles on the survival and growth of sclerophrys arabica tadpoles in a two level trophic system. | under natural conditions pollutants rarely affect only a single trophic level. this study investigated the effects of titanium dioxide (ti-nps) and zinc oxide (zn-nps) nanoparticles on survival and growth of sclerophrys arabica tadpoles exposed directly in water, indirectly through their food source (decomposing leaves), or a combination of both. zn-nps did not cause significant mortality. the lc50 for tadpoles exposed to ti-nps directly was 74.9 µg/l (95% ci 16.6-338.7 µg/l) and 18.3 µg/l (95% ... | 2018 | 30238128 |
