This study aims to evaluate the TiO2 nanoparticles (NPs) and soil type effect on Zea mays L. seedlings assess of NPs retained in organic matter terrestrial isopods (Armadillidium vulgare, Latreille). It was hypothesized that (i) combined pH minerals, addition harm maize plants, (ii) increasing Ti’s content (OM) causes mortality isopods. Under greenhouse conditions, effects (300 600 mg kg?1 dry ...
