Abstract

This study characterizes anthropogenic particles (AP) and microplastics (MP) in treated wastewater, sea surface, water column and intertidal sediments from the Arcachon Bay (France) at four seasons. Their morphometric characteristics, polymer types and concentrations were described. Concentrations showed some seasonal variations that may be related to anthropogenic factors like tourism or fishing. Overall, 2687.4 ± 1335.2 AP.m⁻³ (614.7 ± 481.4 MP.m⁻³) were found in wastewater and we estimated that 127.4 ± 41.6 million of AP (30.0 ± 25.2 million of MP) could enter the Atlantic Ocean each day via the wastewater system. Mean concentrations at sea surface, in water column and intertidal sediments were respectively 0.79 ± 1.64 AP.m⁻³ (0.62 ± 1.30 MP.m⁻³), 778.90 ± 370.95 AP.m⁻³ (319.2 ± 214.6 MP.m⁻³) and 86.93 ± 67.77 AP.kg⁻¹ (16.1 ± 19.1 MP.kg⁻¹ dry weight). Finally, we proposed insights about sources of AP and MP based on their characteristics (e.g. textiles, tyres, fishing).

大西洋沿岸泻湖非生物隔间中微塑料和其他人为颗粒的时间分布

研究了法国Arcachon湾4个季节处理后的废水、海面、水柱和潮间带沉积物中人为颗粒（AP）和微塑料（MP）的特征。描述了它们的形态特征、聚合物类型和浓度。浓度表现出一些季节性变化，可能与旅游或渔业等人为因素有关。总体而言，废水中发现了2687.4±1335.2 AP.m - 3(614.7±481.4 MP.m - 3)，我们估计每天有127.4±4160万AP（30.0±2520万MP）通过废水系统进入大西洋。海面、水柱和潮间带沉积物平均浓度分别为0.79±1.64 AP.m−3（0.62±1.30 MP.m−3）、778.90±370.95 AP.m−3（319.2±214.6 MP.m−3）和86.93±67.77 AP.kg−1（16.1±19.1 MP）。Kg−1干重)。最后，我们根据其特征（如纺织品、轮胎、渔业）提出了对AP和MP来源的见解。

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.
