The role of compost and biochar in the recovery As Sb-polluted soils is poorly investigated, as well influence their application rates on soil health quality. In this study, we therefore investigated effectiveness over time (2, 4, 6 months, M) a municipal solid waste (MSWC) (BC), applied at 10 30% rates, selected mixtures (MIX; total 1:1 ratio MSWC BC), labile Sb polluted from an abandoned mine (Djebel Hamimat, Algeria).

Microbial community responses to environmental stressors are often characterised by assessing changes in taxonomic structure, but such changes, or lack thereof, may not reflect functional that critical ecosystem processes. We investigated the individual and combined effects of nutrient enrichment ( + 10 mg/L N, 1 P) salinisation 15 g/L NaCl)-key freshwater systems-on structure metabolic function benthic microbial communities using 1000 L open ponds established >10 years ago field. Combined drove strong decreases maximum mean total carbon rates shifted profiles compared either stressor individually ambient conditions. These did recover through time occurred without significant alterations bacterial structure. results imply functions, including organic release, likely be impaired under multiple stressors, even when remains stable.

Due to the large number of areas contaminated with TPH, there is significant interest in biological remediation technology research, offering a comprehensive and sustainable approach soil decontamination health recovery at same time. This study aimed investigate effectiveness remediating TPH-contaminated (6120 mg kg−1) using Lotus corniculatus along microorganism consortium (GTC-GVT/2021) isolated from historic sites. evaluated removal TPH through changes nutrient content, enzymatic activity, microbiological community. The growth L. was reduced soil, particularly affecting root biomass by 52.17%. Applying inoculum positively affected total plant uncontaminated (51.44%) (33.30%) soil. GTC-GVT/2021 significantly enhanced degradation after 90 days 20.8% conjunction 26.33% compared control. activity more pronounced treatments, most cases, presence led higher activity. cultivation resulted an increased concentration inorganic P, NH4+, water-soluble phenols while no rise NO3− observed.

The effect of pesticide pollution on environmental microorganisms in soil has become the focus widespread concern society today. response earthworm gut and surrounding microbial functional diversity enzyme activity to carbendazim (CBD) was studied a soil-earthworm ecosystem amended with manure. In experiment, CBD added manured (MS). Meanwhile, treatment without manure control pesticides were also set up. activities catalase (CAT) acetylcholinesterase (AChE) measured evaluate toxicity CBD. Biolog method used assess community. 2 mg/kg treatment, AChE decreased significantly MS after 14 d, which occurred earlier than un-manured (NS). changes CAT treatments showed trend initially increasing then maintaining at high level. However, 28 d soils clearly lower that 7 for both treatments, while they remained stable treatments. carbon source utilization, Simpson index, Shannon McIntosh index higher those NS overall treated control. Also, (2 mg/kg) increased microorganisms. results indicated before Furthermore, exposure concentration not only led inhibition but improved diversity. This study revealed ecotoxicological effects earthworms stress following use organic fertilizers under facility conditions, can provide theoretical basis remediation future.
