Hardy plants play a crucial role in restoring high-altitude tailings ponds, but the accumulation of potentially toxic elements (PTEs) and detoxification mechanisms in alpine plants are understudied. This study first investigated the cadmium (Cd) accumulation capacity and detoxification mechanisms by comparative transcriptomics with different Cd stress (0, 5, 10, 20 and 40 mg L Cd) of Koenigia tortuosa from a lead-zinc mine (4950 m above sea level) in Qinghai-Tibet Plateau. The findings revealed that, despite elevated Cd concentrations suppressed the growth of Koenigia tortuosa, the plant retained a notable ability to accumulate Cd.

This study investigated the stimulation effect of sulfate reducing bacteria (SRB) on Cd bioavailability with the input of different doses MnSO (0.5, 1.

- - Misuse of aromatic amines like 4-chloroaniline has caused serious environmental and health problems, and their degradation by microorganisms is challenging.
- - The study explored using nano-zero-valent iron (nZVI) alongside microbial flora to improve the degradation of 4-chloroaniline, resulting in a bio-degradation rate increase from 43.13% to a maximum of 68.79% under optimal conditions.
- - Analysis showed that nZVI enhances the microbial breakdown of 4-chloroaniline by reducing harmful compounds and promoting dechlorination, while maintaining a stable microbial community during the degradation process.
