Abstract

Pharmaceuticals, stimulants, and biocides enter the environment via wastewater from urban, domestic, and industrial areas, in addition to sewage, aquaculture and agriculture runoff. While some of these compounds are easily degradable in environmental conditions, others are more persistent, meaning they are less easily degraded and can stay in the environment for long periods of time. By exploring the adsorptive properties of a wide range of pharmaceuticals, stimulants, and biocides onto particles relevant for marine conditions, we can better understand their environmental behaviour and transport potential. Here, the sorption of 27 such compounds to inorganic (kaolin) and biotic (the microalgae Cryptomonas baltica) marine particles was investigated. Only two compounds sorbed to microalgae, while 23 sorbed to kaolin. The sorption mechanisms between select pharmaceuticals and stimulants and kaolin was assessed through exploring adsorption kinetics (caffeine, ciprofloxacin, citalopram, fluoxetine, and oxolinic acid) and isotherms (ciprofloxacin, citalopram, and fluoxetine). Temperature was shown to have a significant impact on partitioning, and the impact was more pronounced closer to maximum sorption capacity for the individual compounds.

海水温度和物理化学特性对海洋颗粒吸附药物、兴奋剂和杀菌剂的影响

除污水、水产养殖和农业径流外，药物、兴奋剂和杀菌剂还通过城市、家庭和工业区的废水进入环境。其中一些化合物在环境条件下很容易降解，而另一些则具有较强的持久性，这意味着它们不容易降解，可以在环境中长期存在。通过探索各种药物、兴奋剂和杀菌剂在与海洋条件相关的颗粒上的吸附特性，我们可以更好地了解它们的环境行为和迁移潜力。本文研究了 27 种此类化合物在无机（高岭土）和生物（微藻隐单胞菌）海洋颗粒上的吸附情况。只有两种化合物吸附在微藻上，而 23 种吸附在高岭土上。通过探索吸附动力学（咖啡因、环丙沙星、西酞普兰、氟西汀和草酸）和等温线（环丙沙星、西酞普兰和氟西汀），评估了某些药物和兴奋剂与高岭土之间的吸附机制。结果表明，温度对分配有显著影响，而且这种影响在接近各化合物的最大吸附容量时更为明显。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
