“Nanosize effect” in the metal-handling strategy of the bivalve Scrobicularia plana exposed to CuO nanoparticles and copper ions in whole-sediment toxicity tests

Ecotoxicity testing of nanomaterials in sediment – suggestions to improve science and regulation

“…Methods of homogenization included mixing by hand, on shaking table and via overhead impeller or rotating metal blade and ranged from 1 hour 18 to mixing by hand followed by 72 h on a shaking table 25,26 or periodically over 2 weeks. 27 In addition, our analysis further revealed that for a few studies the method of homogenization was not specified and furthermore many studies present relevant information on procedures in the ESI † section. Thus, highlighting the low priority of reporting the procedure of homogenization.…”
