Petroleum hydrocarbon pollutants in soil are challenging to biodegrade, negatively impacting plant growth as well as the metabolic activity and community structure of soil microorganisms. Microorganisms immobilized by seed carriers can synergistically contribute to the remediation of petroleum hydrocarbon-contaminated soil. We prepared a rape seed carrier with immobilized microorganism by seed coating (with a mixture of diatomaceous earth and bentonite as fillers) and microbial immobilization.

The ultrahigh-sensitive detection of HS is reported using a novel dual-ligand metal-organic framework (MOF) electrochemiluminescence (ECL) sensor. By combining tetrakis(4-carboxyphenyl) porphyrin (TCPP) and 1,3,6,8-tetrakis(4-carboxyphenyl) pyrene (TBAPy) as ligands and employing zirconium as the metal source, a spindle-shaped Zr-PyTCPPMOF was successfully designed and synthesized. Notably, the multiple nitrogen structures of porphyrin provided abundant binding sites for sulfur (S), further enhancing the ECL signal of Zr-PyTCPPMOF.

Methane (CH) processes and fluxes have been widely investigated in low-latitude tropical wetlands and high-latitude boreal peatlands. In the mid-latitude Mongolia Plateau, however, CH processes and fluxes have been less studied, particularly in riverine wetlands. In this study, in situ experiments were conducted in the riverine sandy wetlands of the Mongolia Plateau to gain a better understanding of CH emissions and their influencing mechanisms.

A novel detection technique is introduced that offers sensitive and reliable ochratoxin A (OTA) detection. The method leverages the etching of gold nanorods (AuNRs) stabilized by hexadecyl trimethyl ammonium bromide (CTAB) using the oxidized form of 3,3',5,5'-tetramethyl benzidine sulfate (TMB), creating a susceptible multicolor visual detection system for OTA. The visual detection is enabled by Mg-assisted DNAzyme catalysis combined with the catalytic hairpin assembly (CHA) signal amplification strategy.

Polycyclic aromatic hydrocarbons (PAHs) have been regarded as important environmental carcinogens that can cause lung cancer. However, the underlying epigenetic mechanism during PAHs-induced lung carcinogenesis has remained largely unknown. Previously, we screened some novel epigenetic regulatory genes during 3-methylcholanthrene (3-MCA)-induced lung carcinogenesis, including the potassium inwardly rectifying channel subfamily J member 15 (KCNJ15) gene.
