“…Amongst the studied organisms, the nematode Caenorhabditis elegans has emerged as a reliable toxicity model owing to its several practical and technical advantages [ 76 ]. We found 26 articles [ 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 ] reporting the sublethal effects of environmentally relevant concentrations (µg·L −1 ) of NPs on Caenorhabditis elegans . Of these, twenty-three studies examined the effects of nanoPS alone, whilst the other three considered the enhancement of the toxicity of other stressors in combination with exposure to nanoPS.…”
