“…Indeed, plastic waste is a problem that simultaneously involves economic, social and technological aspects (Vanapalli et al 2021 ; Prata et al 2020 ). In other words, all society issues cannot be solved anymore by the painkiller approach in a globalized word, but required a new world system involving fast evaluation and actions taking into account all aspects of a problem (Lichtfouse 2009 , 2010 ; Lichtfouse et al 2012 ).…”

“…The symmetry effects propagate from the level of molecular spatial transformations, intracellular /cross-membrane molecular transport, cell motility, to the higher hierarchical level of the spatial organization such as the cell proliferation [47], immune defense, environmental chemistry [49], motor behavior, brain cognitive functions, human psychology [50], psychiatry [48,[51][52][53]. The symmetry effects play a critical role in food preparation [54,55], pharmaceutical industry [56,57], design of molecular devices (biosensors and information processing units.…”

“…Using a conversion factor of 53 kg of soil per square meter, they calculate that soils in the eastern part of Fukushima prefecture exceed the government's safe limit of 2,500 Bq/kg of 137 Cs (about half of the total radioactive cesium is composed of 137 Cs) (Yasunari et al 2011). Therefore, in Japan, the 137 Cs fixation and immobilization in contaminated soil is recognized to be one of the most important problems, which should be solved by taking advantage of suitable technologies (Lichtfouse et al 2012).…”

This report shows that cesium can be immobilized in soils with an efficiency of 96.4% by ball milling with nano-metallic Ca/PO 4 . In Japan, the major concern on 137 Cs deposition and soil contamination due to the emission from the Fukushima Daiichi nuclear power plant showed up after a massive quake on March 11, 2011. The accident rated 7, the highest possible on the international nuclear event scale, released 160 petabecquerels (PBq) of iodine 131 I and 15 PBq of 137 Cs according to the Japanese Nuclear and Industrial Safety Agency. Both 137 Cs and 131 I radioactive nuclides are increasing cancer risk. Nonetheless, 137 Cs, with a half-life of about 30 years compared with 8 days for 131 I, is a major threat for agriculture and stock farming and, in turn, human life for decades. Therefore, in Japan, the 137 Cs fixation and immobilization in contaminated soil is the most important problem, which should be solved by suitable technologies. Ball milling treatment is a promising treatment for the remediation of cesium-contaminated soil in dry conditions. Here, we studied the effect, factors and mechanisms of soil Cs immobilization by ball milling with the addition of nano-metallic Ca/CaO/NaH 2 PO 4 , termed ''nano-metallic Ca/PO 4 .'' We used scanning electron microscopy combined with electron dispersive spectroscopy (SEM/EDS) and X-ray diffraction. Results show that immobilization efficiency increases from 56.4% in the absence of treatment to 89.9, 91.5, and 97.7 when the soil is ball-milled for 30, 60 and 120 min, respectively. The addition of nano-metallic Ca/PO 4 increased the immobilization efficiency to about 96.4% and decreased the ball milling time. SEM/EDS analysis allows us to observe that the amount of Cs decreased on soil particle surface. Use of nano-metallic Ca/PO 4 over a short milling time also decreases Cs leaching. Therefore, ball milling with nano-metallic Ca/PO 4 treatment may be potentially applicable for the remediation of radioactive Cs-contaminated soil in dry conditions.
