<![CDATA[The widespread use of pesticides in agriculture, aquaculture, and public health has led to severe environmental and public health concerns due to their overapplication and persistence in ecosystems. Pesticide residues accumulate in soil, degrade its fertility, pollute groundwater, and harm non-target organisms, including beneficial insects and aquatic life. This persistent contamination poses a significant threat to biodiversity, food safety, and ecosystem resilience. The aim of this review is to examine microbial bioremediation as a sustainable and effective strategy for remediating pesticide-contaminated soils. The paper evaluates the mechanisms by which microorganisms degrade or transform hazardous pesticide compounds into less toxic or non-toxic forms and assesses the advantages and limitations of bioremediation technologies. Notably, bioremediation is recognized for its environmental compatibility, cost-effectiveness, and potential to restore soil health without undermining agricultural productivity. Recent studies highlight promising microbial strains capable of degrading diverse classes of pesticides under varying environmental conditions. However, challenges remain, including the scalability of microbial technologies, the complexity of mixed-contaminant sites, and the influence of abiotic factors on microbial efficacy. Future research should focus on optimizing microbial consortia, integrating genetic and metabolic engineering approaches, and developing field-scale applications tailored to specific agroecosystems. Advancing these areas will be critical for establishing bioremediation as a central pillar in sustainable pesticide management and environmental restoration strategies.]]>

<![CDATA[Microplastics are widespread environmental pollutants detected in aquatic, terrestrial, and atmospheric ecosystems. Their persistence, coupled with their potential to bioaccumulate and release toxic additives, raised serious concerns for both environmental and human health. This study aimed to assess microbial biodegradation as a viable strategy for reducing microplastic pollution. The research focused on the mechanisms through which microorganisms, particularly bacteria and fungi, degraded plastic polymers under various environmental conditions. Several microbial strains demonstrated the ability to degrade polymers such as polyethylene, polystyrene, and polyvinyl chloride, albeit at varying efficiencies. Environmental parameters such as temperature, pH, oxygen availability, and nutrient concentration, were found to significantly influence the rate and extent of microbial degradation. Despite these promising findings, the overall degradation rates observed in natural environments remained low. Moreover, challenges related to microbial specificity, metabolic limitations, and the scalability of degradation processes hindered the practical application of microbial treatments on a large scale. The complexity of polymer structures and the additives used in plastic manufacturing further complicated microbial breakdown. To overcome these barriers, future research should prioritize genetic engineering of microbial strains and the optimization of bioprocesses to improve degradation efficiency. Such advancements could pave the way for sustainable and effective biotechnological solutions to mitigate microplastic pollution.]]>

<![CDATA[Petroleum-contaminated soil is a significant environmental concern caused by oil spills, leakage from storage tanks, industrial discharges, and improper disposal of petroleum products during extraction, refining, and transportation processes. Globally, approximately 6 million tonnes of petroleum are released into the environment each year, leading to soil contamination that poses toxic risks to groundwater, ecosystems, plant life, and human health. The primary aim of this paper is to evaluate the effectiveness and potential of microbial bioremediation for treating petroleum-contaminated soils, offering a sustainable alternative to conventional methods. Traditional remediation approaches such as soil excavation, washing, chemical oxidation, and incineration are often expensive and environmentally disruptive. In contrast, bioremediation using microbes is cost-effective, sustainable, and environmentally friendly. Several microbial strategies are discussed, including natural attenuation, bioaugmentation, and biostimulation. Natural attenuation relies on indigenous microbes, whereas bioaugmentation involves adding hydrocarbon-degrading microbes, and biostimulation enhances microbial activity by supplying nutrients. Among these, bioaugmentation and biostimulation are generally more effective than natural attenuation in degrading petroleum hydrocarbons. However, microbial bioremediation faces challenges such as long treatment durations, incomplete degradation with free microbes, and the need for site-specific optimal conditions. Future research should focus on enhancing microbial efficacy through genetic engineering or microbial consortia, developing faster, site-specific solutions, assessing long-term ecological impacts, and integrating bioremediation with other green technologies. Overall, microbial bioremediation presents a promising strategy for the sustainable management of petroleum-contaminated soils due to its low cost, minimal environmental impact, and adaptability. Key topics addressed include the environmental impact of petroleum pollution, conventional and biological remediation techniques, comparative effectiveness, and future development needs. The relevant keywords are: bioremediation, petroleum hydrocarbons, bioaugmentation, soil contamination, and microbial degradation.]]>

<![CDATA[This review synthesizes findings from over 100 recent studies to examine the multifaceted impacts of microplastics on soil health. Microplastics affect soil nutrient dynamics through mechanisms such as chemical leaching, nutrient adsorption, microbial shifts, and physical alterations in soil structure. Their influence varies by polymer type, particle morphology, concentration, and environmental conditions. While some microplastics may enhance nutrient retention, many contribute to nitrogen and phosphorus depletion, undermining soil fertility and agricultural productivity. Microplastics also modify soil pH in inconsistent ways, either increasing or decreasing it, thereby disrupting nutrient availability and microbial functions. The effects of microplastics on soil organic matter are equally complex. Biodegradable microplastics can stimulate microbial respiration and increase dissolved organic carbon, but they may also destabilize carbon pools, depending on the environmental context and soil conditions. Additionally, microplastics act as vectors or sinks for organic pollutants and heavy metals through diverse sorption–desorption mechanisms. Their interactions with contaminants such as pesticides, pharmaceuticals, and metals like lead, cadmium, and zinc are influenced by polymer type, surface aging, and coexisting soil constituents. Microplastics not only impair nutrient cycling but also alter microbial community composition, enzymatic activity, and pollutant degradation, raising concerns about the function of soil ecosystems and food safety. Future research should prioritize long-term, multi-factorial experiments under realistic environmental conditions. Key areas include disentangling the effects of conventional versus biodegradable microplastics, developing mechanistic models of pollutant interactions, and assessing the role of environmental parameters in mediating metal binding. Such efforts are vital for accurate risk assessments and informed mitigation strategies in terrestrial ecosystems.]]>

<![CDATA[Urban land degradation poses a growing challenge in rapidly developing countries like Indonesia, where population growth and limited space drive uncontrolled land cover changes. This study aims to detect land degradation in urban areas through spatial modelling and semi-automatic classification of multi-temporal remote sensing imagery. Landsat-5 Thematic Mapper (TM) image from year 2011 and Landsat-9 Operational Land Imager collection 2 (OLI-2) image from year 2023 data were acquired from the The United States Geological Survey (USGS). Image pre-processing included band stacking, subsetting, and enhancement to improve visual interpretation. Semi-automatic supervised classification was applied to map seven land cover classes: agricultural dry land, rice field, forest, plantation, non-agricultural land, water body, and settlement. Training data and validation were supported by Google Earth Pro, official sources, and field surveys using random sampling. Change detection analysis revealed a 1664.65 ha increase in industrial areas, accompanied by significant reductions in rice fields (−1726.92 ha) and dry farmland (−1644.57 ha). The classification accuracy reached 80.24% and 75.11%, with kappa coefficients of 0.76 and 0.65, respectively. Results indicate that urban expansion is a key driver of land degradation, particularly through the loss of productive agricultural land. This research demonstrates the effectiveness of remote sensing-based spatial modelling and classification techniques for monitoring urban land degradation and informing sustainable land use planning.]]>

<![CDATA[Organophosphates (OPs) were synthetic chemical compounds that had been applied in household products as well as in agricultural and industrial sectors. Although OPs had proven effective, particularly as pesticide ingredients, their persistence in the environment had raised concerns regarding impacts on ecosystems, the environment, and human health. This study addressed the occurrences and negative impacts of OPs, with a primary focus on microbial degradation as a bioremediation strategy. While various degradation methods had been developed, microbial degradation showed strong potential as a sustainable and cost-effective approach. This review aimed to examine the mechanisms, benefits, and limitations of microbial degradation of OPs, thereby addressing the knowledge gap related to its real-world applications. Microbial degradation involved the use of bacteria capable of breaking down OPs through enzyme production, transforming them into less harmful substances. In comparison with chemical or physical methods, microbial degradation was more environmentally friendly, cost-effective, and adaptable to surrounding conditions. By synthesizing findings from previous studies, the report highlighted both the strengths and shortcomings of microbial degradation in mitigating OPs contamination. The findings underscored its promise as a viable solution, while also pointing to the need for further research and improved frameworks.]]>

<![CDATA[Microalgae-based remediation of palm oil mill effluent (POME) grew rapidly, yet evidence remained dispersed across methods and outcomes. This study undertook bibliometric mapping to organise research growth, thematic structure, and actionable pathways aligned with SDGs 6, 7, 12, and 14. A Scopus database of 124 articles (2008–2025) was analysed with VOSviewer to produce keyword co-occurrence and temporal overlays, complemented by impact indicators and close reading of highly cited studies. Output increased from a formative phase to a peak in 2021, with 3275 citations overall and influence that was concentrated yet broad (h = 35; g = 51; m = 1.944). The network resolved into a central focal point (POME, microalgae, effluent/wastewater), surrounded by two related fields: pollutant metrics (COD, nitrogen, phosphorus), which supported treatment claims, and valorisation (biomass, lipid, biofuel), which linked remediation to product streams. Temporal overlays showed a progression from feasibility and nutrient polishing to method-rich optimisation (kinetics, immobilisation) and, more recently, to cultivation realism, phycoremediation, and sustainability. These patterns indicated practical levers for mill-scale deployment, including on-site cultivation with boiler CO₂, microalgae–bacteria partnerships for robustness, and combined pond–photobioreactor systems that balanced cost and control. Together, these combinations delivered cleaner effluents (SDG 6), low-carbon energy vectors (SDG 7), circular nutrient and residue reuse (SDG 12), and reduced land-based marine pollution (SDG 14). Remaining priorities included harmonised reporting of removals and yields, techno-economic and life cycle assessments at mill cluster scale, resilient process control and safety for multi-stage systems, and biomass quality assurance to safeguard downstream uses.]]>

<![CDATA[Environmental contamination from sunscreen ingredients such as oxybenzone and octinoxate has become an increasing concern due to their persistence and toxicity, even at trace concentrations. Continuous sunscreen usage leads to the constant release of these pollutants into the environment, where they can bioaccumulate and resist degradation. The novelty of this review lies in its focused synthesis of recent studies on the microbial and enzymatic degradation mechanisms of sunscreen contaminants, particularly oxybenzone and octinoxate, which exhibit high persistence and bioaccumulative potential. Microbial degradation offers a promising biological approach for the breakdown of these organic pollutants, as microorganisms have demonstrated strong biodegradative capabilities toward various environmental contaminants. This process relies on microbial enzymes that transform or mineralize pollutants into less toxic and simpler compounds. Key enzymes involved include laccase, cytochrome P450, and monooxygenase, which catalyze oxidation, reduction, and hydroxylation reactions. The article further examines these organic pollutants in terms of their persistence, environmental occurrence, degradation mechanisms, and pathways, while also addressing their ecological and health impacts. Moreover, different microbial-based treatment technologies are evaluated, highlighting their respective strengths and limitations. Finally, the review emphasizes the need for continued research into organic pollutant behavior and bioremediation technologies to deepen understanding and mitigate the adverse effects of these contaminants on the environment.]]>

<![CDATA[The study evaluated the acute and sub-lethal effects of ethanol extract of Senna alata stem bark on physicochemical parameters and haematological indices of Clarias gariepinus fingerlings. A 96-hour acute toxicity bioassay established an LC₅₀ of 11.54 mg/l (95% CI: 10.92–12.16 mg/l) and an LC₉₉ of 23.30 mg/l (95% CI: 21.75–24.85 mg/l), with mortality increasing from 0% in the control to 85% at 12.6 mg/l. Sub-lethal concentrations (0.61, 0.71, and 0.81 mg/l, corresponding to 1/20th, 1/16th, and 1/14th of LC₅₀, respectively) were applied for eight weeks. Physicochemical parameters (pH, temperature, total dissolved solids, electrical conductivity, and dissolved oxygen) were monitored before and after extract application. Electrical conductivity differed significantly at 0.61 mg/l (p = 0.0351), while other parameters remained statistically unchanged, although dissolved oxygen declined progressively with increasing concentration. Haematological analysis revealed no significant changes (p > 0.05) in haemoglobin, mean corpuscular haemoglobin, mean corpuscular volume, packed cell volume, platelet, red blood cell, and white blood cell counts, except for a significant alteration in mean corpuscular haemoglobin concentration (p = 0.0479). These findings demonstrate that S. alata exhibits moderate piscicidal toxicity under acute exposure and induces mild physiological stress under sub-lethal conditions, which could have long-term implications for fish health and aquaculture productivity. The use of S. alata as a piscicide should therefore be approached cautiously to prevent unintended ecological consequences. Future studies should evaluate histopathological and biochemical stress responses to establish environmental safety limits for S. alata in aquaculture systems.]]>
