“…Further studies using the same approach on phytoliths exposed to a range of temperatures could help to further document the transformations. Nguyen et al (2021) performed leaching tests on rice straw after dry ashing. They observed a concomitant release of Si and As, and suggested that As could be associated with the phytolith structure, but they did not provide direct evidence for this hypothesis.…”

“…In addition, silicon is beneficial for plant fitness, and was shown to alleviate metal toxicity (Adrees et al, 2015). Recent studies have shown the presence of metals and metalloids in phytoliths in plants growing in contaminated environments (Buján, 2013;Lisztes-Szabó et al, 2019;Delplace et al, 2020;Nguyen et al, 2021;Nguyen et al, 2019;Tran et al, 2019). It was suggested that phytoliths are involved in a detoxification mechanism (Buján, 2013;Delplace et al, 2020;Rizwan et al, 2016), and that phytoliths could play an important role in metal (Nguyen et al, 2021;Tran et al, 2019) and carbon (Song et al, 2016) biogeochemical cycle in soils.…”

In a recent review, Hodson and Evans (2020) also showed that codeposition of Al and Si in phytoliths is a fairly common phenomenon in the plant kingdom, especially in acidic soils, and this may be important in detoxification of Al.…”

“…The outer surface of RS shows large globular and small spiked symmetrically arranged grid-like structures of phytoliths [40,41]. These phytoliths occurred in different shape and size throughout the RS surface [42]. These structures were covered by a silica layer and are responsible for the hydrophobic nature of RS [43,44].…”

Managing rice crop stubble is one of the major challenges witnessed in the agricultural sector. This work attempts to investigate the physical, mechanical, and liquid absorption properties of rice straw (RS)-reinforced polymer composite for assessing its suitability to use as an ayurvedic treatment table. This material is expected to be an alternative for wooden-based ayurvedic treatment tables. The results showed that the addition of rice straw particles (RSp) up to 60% volume in epoxy reduced the density of the composite material by 46.20% and the hardness by 15.69%. The maximum tensile and flexural strength of the RSp composite was 17.53 MPa and 43.23 MPa, respectively. The scanning electron microscopy (SEM) analysis showed deposits of silica in the form of phytoliths in various size and shapes on the outer surface of RS. The study also revealed that the water absorption rate (WA) was less than 7.8% for the test samples with 45% volume of RSp. Interestingly the test samples showed greater resistance to the absorption of Kottakal Dhanvantaram Thailam (<2%). In addition, the developed samples showed resistance towards bacterial and fungal growth under the exposure of treatment oils and water.

“…Second, phytolith is highly resistant to decomposition in environmental conditions. Phytolith can accumulate a significant amount of trace elements and remain in the soil after plant organic matter is decomposed [9,12]. After phytolith returns to the soil, trace elements in phytolith are stable and do not decompose in various weather and water conditions [8].…”

In South Korea, most metal mines were abandoned and caused contamination for more than 30 years. Even the soil is highly contaminated with trace elements, plants still grow in the area and can affect the contamination. Phytolith is amorphous silica in the plant body. Phytolith is resistant to decomposition, and the stabilization of carbon, nutrients, and toxic substances accumulated in the phytolith is being studied. In this study, the Gilgok gold mine, which is contaminated with arsenic was selected as the research site. We selected Phragmites japonica and Thelypteris palustris as targets for the analysis of arsenic accumulation in plants and phytolith. Plants accumulate more phytolith at the riverside. The higher water content of soil increased the Arsenic (As) concentration in the frond of the T. palustris. Soil available silicon (Si) did not affect phytolith accumulation but increased As accumulation in the plant and phytolith. The research result showed that P. japonica and T. palustris have the ability to accumulate As in phytolith and the accumulation can be changed with soil characteristics and plant species. This As accumulation in phytolith can affect plant tolerance in contaminated areas and change the As availability in the soil. The result of the research can be used as a database to build a sustainable environment.
