AI Article Synopsis
- The study examined how trace elements (Cs, Li, Be, Sr, and Ba) leach from plant growth media made from two types of coal fly ashes and their mixtures with soil and sphagnum peat moss.
- Leachate samples were collected after every half pore volume, totaling five pore volumes, and analyzed for trace element concentrations using ICP emission spectrophotometry.
- The findings indicated that adding sphagnum peat moss and soil to the coal ash media reduced the leaching of trace elements, although high levels of Li, Sr, and Ba in the leachate raised environmental health concerns, suggesting the need for further research.
Article Abstract
This study investigated the leaching of selected trace elements (Cs, Li, Be, Sr, and Ba) from plant growth media made of two coal fly ashes (one from semi-bituminous coal and one from lignite), and from these ashes combined with the soil and with the soil and sphagnum peat moss. Leachate fractions will be collected at each ½ pore volume for a total of five pore volumes. Concentrations of mentioned above trace elements in plant growth media and in leachate has been determined using inductively coupled plasma (ICP) emission spectrophotometry. The presence of sphagnum peat moss and soil in coal ash based plant growth media expressed ameliorative role reducing the presence of trace elements in the leachate. Elevated concentrations of Li, Sr and Ba in the leachate may cause some en environmental health concerns and require further investigations.

Background: Melanoma is an aggressive skin tumor with limited therapeutic options due to rapid proliferation, early metastasis, and poor prognosis. Baicalin (BA), a natural flavonoid, shows promise in inducing ferroptosis and apoptosis but faces challenges of poor solubility and bioavailability. To address these issues, we developed a multifunctional drug delivery system: manganese-doped ZIF-8 nanoparticles (ZIF(Mn)) loaded with BA and modified with folic acid (FA) and polyethylene glycol (PEG).

Arsenic (As) is a common toxic pollution element. The microorganism-mediated transformation of arsenic forms is an important part in the biogeochemical cycle of As. In the various microbial metabolic processes involving As, the coupling reduction of As has a great impact on the environment and is a process that is easily overlooked.

Four-dimensional printing (4DP) technologies can expand the functionality of stimuli-responsive devices to enable the integration of multiple stimuli-responsive parts into a compact device. Herein, we used digital light processing three-dimensional printing technique, flexible photocurable resins, and photocurable resins of the temperature-responsive hydrogels comprising -isopropylacrylamide (NIPAM), ,'-methylenebis(acrylamide) (MBA), and graphene for 4DP of a lab-on-valve (LOV) solid-phase extraction (SPE) device. This device featured flow manifolds and a monolithic packing connected by four near-infrared (NIR)-actuated temperature-responsive switching valves composed of a poly(NIPAM/MBA) (PNM) ball pushing a flexible membrane.
