Naproxen as an emerging environmental contaminant: Microbial degradation mechanism and optimization strategies.
Review in Biodegradation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Naproxen, a non-steroidal anti-inflammatory drug (NSAID), has emerged as a contaminant of concern due to its environmental persistence, incomplete removal by conventional wastewater treatment processes, and associated ecological risks. It has been detected at concentrations ranging from nanograms to micrograms per liter in surface waters, wastewater effluents, and, in some cases, drinking water, particularly in regions with limited treatment infrastructure. Several bacterial genera, such as Pseudomonas and Bacillus, have been reported to transform naproxen through hydroxylation and ring-modification reactions catalyzed by specific enzymes. Microbial consortia, when provided with optimal pH, temperature, oxygen, and nutrient conditions, demonstrate greater degradation efficiency compared to single strains. Despite extensive research on pharmaceutical pollution, a comprehensive understanding of naproxen biodegradation and the environmental factors influencing its removal remains limited. This review synthesizes current knowledge on the occurrence of naproxen in aquatic environments, microbial degradation pathways, and the influence of the combined effects of microbial characteristics and abiotic parameters, including pH, temperature, oxygen availability, and nutrient supply, on degradation efficiency. Several key knowledge gaps remain, including an incomplete understanding of metabolic pathways utilized by diverse microbial communities, the impact of emerging contaminants on naproxen degradation, and the long-term ecological implications of residual naproxen in treated effluents. In addition, challenges related to scaling laboratory findings to real-world applications and integrating biodegradation with other treatment technologies require further investigation. By integrating dispersed findings into a unified conceptual framework, this review identifies critical knowledge gaps and proposes future research directions to advance biologically based strategies for pharmaceutical wastewater treatment.
