Effects of Microplastics Exposure on the Feeding of the Heterotrophic Dinoflagellate Species Noctiluca scintillans
The pollution effects of microplastics (MPs) on the feeding of the heterotrophic dinoflagellate species, Noctiluca scintillans, was investigated. The algal prey species, Dunaliella tertiolecta, was fed to N. scintillans and fluorescent microspheres were used as surrogates for microplastic wastes. Holling's type II functional response model revealed that N. scintillans could reach a maximum prey ingestion rate of 2,242 cells grazer−1 d−1 (~ 214 ngC grazer−1 d−1) under normal conditions. In exposure to a mixture of prey and MPs, N. scintillans showed mean prey ingestion rates of 1,078 and 820 cells grazer−1 d−1 at Prey:MP ratios of 500:1 (i.e., ~ 88 MP particles mL−1) and 5000:1 (i.e., ~ 8 MP particles mL−1), respectively. The number of N. scintillans cells with ingested MP particles increased with decreasing Prey:MP ratios (200:1, 50:1, 10:1, and 1:1), indicating the non-selective feeding between the algal prey and MP particles. This study is the first one to investigate the effects of microplastic pollution on this common red-tide-causing dinoflagellate species. We urge that more research is needed to reveal the ecological implications of microplastic pollution in the marine ecosystems.
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.
