An analytical method was developed for determination of Cd, Sn, Pd, Pt and Rh in sediments, fertilizer and sludge samples by inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). The performance of ICP-MS/MS using oxygen into the octopole reaction system (ORS3) and MS/MS mode, on mass and shift mass, was evaluated to overcome spectral interferences. Addition and recovery experiments in sediments, fertilizer and sludge samples at three concentration levels, 0.5, 1.0 and 5.0 μg L− 1, were carried out to evaluate the accuracy of the developed procedure. Quantitative recoveries, from 80 to 113% for 112Cd+, 120Sn+ and 106Pd+ were reached using MS/MS in on mass operation mode. For Pt and Rh, recoveries ranged from 81 to 117% by monitoring 195Pt16O+ and 103Rh16O+ in MS/MS (shift mass mode) with 0.3 mL min− 1 oxygen gas flow rate pressurized into the ORS3. Limits of detection of the developed method were 15, 2.5, 1.8, 9.0 and 9.9 μg kg− 1 for 195Pt16O+, 103Rh16O+, 112Cd+, 120Sn+, and 106Pd+, respectively. All analytes were simultaneously interference-free determined by ICP-MS/MS, which demonstrates the potential of this instrumental analytical strategy for Cd, Sn, Pd, Pt, and Rh determination in complex samples. |

Arbuscular mycorrhizal fungi (AMF) play a crucial role in plant health due to their ability to improve tolerance to biotic and abiotic stresses. Our aim was to evaluate the effectiveness of a pool of native AMF from a harsh environment on plant performance and changes in soil attributes under different levels of drought. An experiment using maize was established, varying the soil water content to simulate severe drought (30% of the water-holding capacity [WHC]), moderate (50% of the WHC) and no drought (80% of the WHC, control treatment). Soil and plant attributes were measured (enzyme activity, microbial biomass, AMF root colonisation and plant biomass and nutrient uptake). There was a two-fold increase in plant biomass under moderate drought when compared to no drought treatment, but there was no difference in nutrient uptake. Under severe drought, there were the highest enzyme activities related to phosphorus (P) cycling and P microbial biomass, indicating higher P microbial immobilization. The increase in AMF root colonisation was observed in plants under moderate and no drought. Our findings demonstrated that the better use of the AMF inoculum varied according to drought levels, with better performance under moderate drought due to the increase in plant biomass. |
