Determination of strobilurin fungicides residual in vegetables based on amino modified magnetic graphene oxide solid phase extraction coupled with GC-MS/MS.

This research investigated the creation and utilization of an amino-functionalized magnetic graphene oxide (Fe₃O₄-NH₂@GO) nanocomposite as a selective sorbent for extracting and identifying strobilurin fungicides (SFs) from vegetable samples. The investigation utilized a method where magnetic solid phase extraction (MSPE) was integrated with Gas chromatography-triple quadrupole mass spectrometer (GC-MS/MS) for analysis. The physicochemical properties of synthesized sorbent were characterized using Scanning electron microscope (SEM) , Fourier infrared transform spectrum (FT-IR) , X Ray Diffraction (XRD), and vibrating sample magnetometry (VSM) techniques.

Factors controlling the heavy metal ion activity in soil contaminated by microplastics with different mulch durations: Partial least squares path model.

Film covers have been widely applied worldwide. However, the effects of long-term plastic film mulching use on heavy metal (HM) activity in soil remain unclear. This study focused on farmland in the upstream part of the Pearl River in China and collected 103 soil samples after 2, 5, and 15 years of plastic film mulching.

Polyethylene and poly (butyleneadipate-co-terephthalate)-based biodegradable microplastics modulate the bioavailability and speciation of Cd and As in soil: Insights into transformation mechanisms.

Microplastics (MPs) that enter the soil can alter the physicochemical and biochemical properties of soil and affect speciation of heavy metals (HMs), thereby perturbing the bioavailability of HMs. However, the mechanisms underlying these effects are not understood. Therefore, we investigated the effects of MPs from poly (butyleneadipate-co-terephthalate)-based biodegradable mulch (BM) and polyethylene mulch (PM) in Cd- or As-contaminated soil on soil properties and speciation of HMs.

Effects of polyethylene and biodegradable microplastics on photosynthesis, antioxidant defense systems, and arsenic accumulation in maize (Zea mays L.) seedlings grown in arsenic-contaminated soils.

Arsenic (As) and microplastic (MP) co-exposure is a major environmental problem in terrestrial ecosystems. Polyethylene and biodegradable plastics decompose into MP particles under microbial-mediated and weathering conditions. However, the effects of MP particles on physiological responses and As accumulation in maize have not been thoroughly explored.

RNA-targeting CRISPR systems from metagenomic discovery to transcriptomic engineering.

Deployment of RNA-guided DNA endonuclease CRISPR-Cas technology has led to radical advances in biology. As the functional diversity of CRISPR-Cas and parallel systems is further explored, RNA manipulation is emerging as a powerful mode of CRISPR-based engineering. In this Perspective, we chart progress in the RNA-targeting CRISPR-Cas (RCas) field and illustrate how continuing evolution in scientific discovery translates into applications for RNA biology and insights into mysteries, obstacles, and alternative technologies that lie ahead.
