Dual effects of nZVI on maize growth and water use are positively mediated by arbuscular mycorrhizal fungi via rhizosphere interactions.

Environ Pollut 2022 Jun 21:119661. Epub 2022 Jun 21.

State Key Laboratory of Grassland Agroecosystems, College of Ecology, Lanzhou University, Lanzhou, 730000, China. Electronic address:

Nanoscale zero-valent iron (nZVI) might generate positive and negative effects on plant growth, since it acts as either hazardous or growth-promotion role. It is still unclear whether such dual roles can be mediated by arbuscular mycorrhizal fungifungi (AMF) in plant-AMF symbiosis. We first identified that in 1. Read More

Airborne polar pesticides in rural and mountain sites of North-Eastern Italy: An emerging air quality issue.

Environ Pollut 2022 Jun 21:119657. Epub 2022 Jun 21.

Department of Environmental Sciences, Informatics and Statistics, Ca' Foscari University of Venice, Via Torino, 155-30172 Venice Mestre (VE), Italy; Institute of Polar Sciences, National Research Council (CNR-ISP), Via Torino, 155-30172 Venice Mestre (VE), Italy.

North-Eastern Italy and in particular Veneto Region, stands out as a major centre of agriculture and viticulture which has rapidly expanded in the last decade with high productivity indexes. In this context, assessing atmospheric pollution caused by crop spraying with pesticides in rural areas and their transport to high-altitude remote sites is crucial to provide a basis for understanding possible impacts on the environment and population health. We aim to improve existing methods with a highly sensitive technique by using high pressure anion exchange chromatography coupled to a triple quadrupole mass spectrometer. Read More

Sci Total Environ 2022 Jun 21:156859. Epub 2022 Jun 21.

Centre for Regional and Rural Futures, Faculty of Science, Engineering and Built Environment, Deakin University, Burwood, VIC 3125, Australia. Electronic address:

A 620-day batch experiment was conducted to examine the generation of nano-sized plastic particles and migration of organic compounds derived from plastic additives and impurities during the weathering of three common plastic types in water with and without reactive oxygen species. The results show that the amount of nanoplastics plus organic compounds liberated from the tested plastic films, as indicated by total organic carbon, was in the following decreasing order: PET >PP > ABS. Hydroxyl radical generated from Fenton-like reaction significantly enhanced the generation of nanoplastics and release of organic compounds from the weathered plastic films via oxidative degradation.

Novel sandwich-type electrochemiluminescence aptasensor based on luminol functionalized aptamer as signal probe for kanamycin detection.

Bioelectrochemistry 2022 Jun 6;147:108174. Epub 2022 Jun 6.

Ecological Agriculture Development Company Limited, Rongbing Quyang Village, Zhenjiang 212001, Jiangsu Province, China.

A novel sandwich electrochemiluminescence (ECL) aptasensor was developed for highly sensitive detection of kanamycin using luminol-functionalized aptamer as a signal probe. The aptasensor used polyethyleneimine (PAMAM), molybdenum disulfide, and multi-walled carbon nanotubes as the substrate, which provided enough binding sites for aptamer1 (the aptamer which modified NH) coupling. We found that kanamycin could be detected using the aptamer1 containing the same base sequence as aptamer2 (the aptamer which modified SH) on the electrode self-assembly. Read More
