摘要
在水环境中，微塑料（MPs）由于其特殊的载体表面特性而容易被生物膜定植，这可能会增强对有害污染物的吸附。本研究旨在探讨生物膜定殖对MPs表面理化性质变化及对有机微污染物吸附的影响。将聚乙烯（PE; 200 μm）微球、商用PE膜（5 mm × 5 mm）和农用（博湖收集）PE膜（5 mm × 5 mm）与莱茵衣藻在BG-11培养基和天然水中共培养28 d，比较不同PE MPs在生物膜定殖前后对磺胺乙嘧啶（SMZ）的吸附性能。值得注意的是，与没有生物膜的PE MPs相比，生物膜定殖使所有PE MPs对SMZ的吸附量增加了2 - 2.6倍。PE颗粒、商用PE膜和蒸馏水培养的博湖收集PE膜对SMZ的吸附分别提高了39.5%、60.0%和62.7%。此外，微米级MPs对污染物的吸附能力比毫米级MPs提高了1.6-2倍。PE MPs吸附SMZ主要受CH/π、静电和氢键相互作用的影响。总体而言，本研究表明生物膜定殖增强了mp相关污染物的吸附，为自然水体中mp -污染物的相互作用提供了见解，并为生态风险评估提供了理论基础。
Effects of biofilm modification on polyethylene microplastics-associated sulfamethazine adsorption
In aqueous environments, microplastics (MPs) are susceptible to biofilm colonization owing to their special carrier surface characteristics, which may enhance the adsorption of harmful pollutants. This study aimed to investigate the effect of biofilm colonization on the changes in the surface physicochemical properties of MPs and the adsorption of organic micropollutants. Polyethylene (PE; 200 μm) pellets, commercial PE film (5 mm × 5 mm), and agricultural (Bohu-collected) PE film (5 mm × 5 mm) were co-cultured with Chlamydomonas reinhardtii in BG-11 medium and natural water for 28 d, and the adsorption properties of different PE MPs before and after biofilm colonization for sulfamethazine (SMZ) adsorption was compared. Notably, biofilm colonization increased SMZ adsorption by all PE MPs by 2–2.6-fold compared with that by PE MPs without biofilm. SMZ adsorption by PE pellets, commercial PE film, and Bohu-collected PE film cultured in distilled water increased by 39.5%, 60.0%, and 62.7%, respectively. Moreover, the adsorption capacity of pollutants was increased by 1.6–2 times for micron-sized MPs compared to millimeter-sized MPs. Mainly, CH/π, electrostatic, and hydrogen bonding interactions were involved in SMZ adsorption by PE MPs. Overall, this study shows the enhancement in MP-associated pollutant adsorption due to biofilm colonization, providing insights into MP–pollutant interactions in natural waters and a theoretical basis for ecological risk assessment.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
