Microplastics and Antibiotics in Aquatic Environments: A Review of Their Interactions and Ecotoxicological Implications

Tropical Aquatic and Soil Pollution, Journal Year: 2024, Volume and Issue: 4(1), P. 60 - 78

Published: June 9, 2024

Microplastics and antibiotics are two significant emerging pollutants found together in water bodies, raising concerns about their mutual effects. This review delves into how microplastics interact aqueous environments the ecotoxicological implications of such interactions, particularly bioavailability prevalence antibiotic-resistance genes. It outlines that attach to primarily through hydrophobic, hydrogen-bonding, electrostatic interactions. Other bonds, comprising halogen bonding, cation−π interaction, negative charge-assisted hydrogen may also be involved better explain antibiotic adsorption patterns. The often follows pseudo-second-order kinetic model some instances, pseudo-first-order model. common isotherms governing this interaction linear Freundlich models. increase biodegradation adsorbed due presence antibiotic-degrading bacteria biofilms. They could hamper direct photodegradation but facilitate indirect antibiotics. However, photodegradative effect remains inconclusive. exhibit toxicity algae, while effects on fish daphnia less noticeable, suggesting combination does not pose an immediate threat well-being proliferation larger aquatic organisms.

Sustainable Biodegradation of Triclosan and Sulfamethoxazole with Cyanobacteria: Resistance Mechanism and Metabolic Transformation

ACS ES&T Water, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Pharmaceuticals and personal care products (PPCPs) are emerging pollutants in aquatic environments, posing significant ecological risks. Cyanobacteria, as primary producers ecosystems, crucial for ecosystem health. Understanding the toxicological effects metabolic mechanisms of PPCPs cyanobacteria is essential evaluating environmental risks bioremediation feasibility. This study reveals that while both sulfamethoxazole (SMX) triclosan (TCS) inhibit algal growth by reducing photosynthetic pigment synthesis activity, Synechocystis sp. PCC 6803 shows markedly different sensitivities to these compounds. The 72-h EC50 values TCS SMX were 14.55 μg/L 19.74 mg/L, respectively. Despite differences, achieved removal rates 89.58% 87.60% SMX. Biodegradation was mechanism both, but also involved biological adsorption bioaccumulation, absent hydrophilic Metabolic pathway analysis identified glycosyltransferase-mediated reactions key metabolism, N4-hydroxylation-SMX (m/z 270) a critical intermediate degradation. Notably, sll1732 gene found play pivotal role research offers insights into interactions between PPCPs, highlighting its potential environmentally sustainable bioremediation.
