Fate and Impact of Microplastics in Marine Ecosystems From the Coastline to the Open Sea [Book]

Fate and Impact of Microplastics in Marine Ecosystems: From the Coastline to the Open Sea brings together highlights from the conference proceedings for MICRO 2016: Fate and Impact of Microplastics in Marine Ecosystems: From the Coastline to the Open Sea.

While the presence of microplastics in ecosystems has been reported in the scientific literature since the 1970’s, many pressing questions regarding their impacts remain unresolved. This short format title draws from the shared scientific and technical material and summarizes the current research and future outlook.

  • Includes a range of topics, from macro- to microplastics
  • Presents data from source to sink, including occurrence and distribution of microplastics in freshwater bodies, coastal zones, and the open ocean
  • Presents the impacts of microplastics on marine life as well as microplastics as vectors of biological and chemical contaminants
  • Provides important analysis on solutions and next steps

Study and analyse of spatial distribution of waste in the southern Atlantic of Morocco

The ocean remains one of the most mysterious and diverse places on Earth. Unfortunately, nowadays our oceans are much polluted: discarded plastic, industrial waste and unwanted fishing nets. This is still a growing problem for the world’s oceans and constitute a threat to both people and oceanic life.

This paper aims to identify and localize the ocean waste pollutant in the Atlantic Ocean of Morocco. To achieve this goal, we participated in a scientific trawling survey made by the National Institute of Fisheries Research (INRH) in the southern Moroccan Atlantic area. Our sampling network consisting of 100 stations distributed in a random method. Several types of waste found in the sea are mainly made of glass, metal, fishing equipment and octopus pots that are used in artisanal fishing for octopus hunting, also a large amount of plastic was found such as bottles, plastic bags, etc.

To analyze the collected information, GIS tools and statistical analysis were used. The result shows that 80% of the southern Moroccan Atlantic ocean wastes are plastic followed by metal, textile, rubber and glass. The concentration of these wastes is usually correlated to a set of factors such as the proximity to the artisanal fishes sites, and to the current effect.

Microplastics, nanoplastics and co-contaminants: Effects and risk assessment for biota, the environment and human health

Chairs: Matthew Cole, Ana I Catarino, Maria Cristina Fossi, Albert Koelmans

Plastic pollution is one of today’s major environmental issues. The widespread contamination of the environment with plastics of all sizes is receiving growing interest from the scientific community, the public and policy makers. Microplastics (microscopic plastics, <5 mm) and nanoplastics (nanoscopic plastics, <100 nm) can be directly manufactured, or derive from the fragmentation of larger debris. Owing to their hydrophobicity and relatively large surface areas, these plastic particulates can accumulate metals and persistent organic pollutants (POPs) and/or develop microbial biofilms, hosting potentially pathogenic microbes. Microplastics are readily consumed by a wide range of marine biota which can impair the health of the individual with potential adverse outcomes for ecological processes. The risks plastic particulates pose to human health is an emerging topic of concern. Here we focus on better understanding the effects plastic particulates and associated co-contaminants have on biota, from the sub-organismal to community levels of biological organisation, and human health. This session aims to discuss three main questions: (1) What are the mechanisms underlying the effects observed in the laboratory and in the field?; (2) What are the consequences of these mechanisms and observations for environmental exposure, effects and risks, including human health?; and, (3) How can scientific knowledge inform mitigation strategies and policy? We invite high quality contributions that provide either innovative methodologies of general importance, novel mechanistic understanding of effects of plastics, or that show to what extent scientific knowledge from adjacent disciplines can be used for the risk assessment of plastic particulates. We encourage research testing biomarkers of fitness with ecological consequence (i.e. maintenance, growth, survival and reproduction), using concentrations with environmental relevance, or which consider the risk plastics pose to ecological health and processes including ecological modelling. Investigations, and development of pathways and risk assessment, which consider routes by which humans may be exposed, or assess toxicological risk of micro- and nanoplastics to humans are encouraged.

Session details can be found in the scientific programme: http://brussels.setac.org/programme/scientific-programme/ – see Track 4: Ecological risk assessment and human health risk assessment of chemicals and other stressors and mixtures, Page 18. A session considering the monitoring and distribution of microplastics within the marine environment is also available within Track 4.

MantaRay: A Novel Autonomous Sampling Instrument for In Situ Measurements of Environmental Microplastic Particle Concentrations

Presented here is the initial hardware and software design of a prototype autonomous microplastic sampling instrument. Microplastics are defined as particles of plastic < 5 mm greatest dimension. They are becoming pervasive in the world ocean due to anthropogenic pollution. The ocean has spatially variable concentrations of surface microplastics, so attempting to identify trends in global dispersal patterns is difficult and expensive using current research techniques. Understanding the global dispersion patterns and degradation rates of microplastics will help to uncover the associated human and ecosystem impacts. A novel low-cost oceanographic sensor has been developed that can determine the concentration of marine microplastics over large spatial areas. This sensor can remove plastic particulates from seawater and archive them for later analysis, determine microplastic concentrations for 28 discrete samples recording GPS position, and simultaneously measure salinity and water temperature. This sensor has been designed around the open-source Arduino platform, allowing for maximum implementation of additional sensors and systems in future prototypes. The MantaRay sensor can be implemented on a drifter, mooring, or Autonomous Underwater Vehicle to gather diverse data on the dispersion of microplastics. This sensor could drastically cut research costs associated with studying deep-sea microplastic concentrations and increase our understanding of plastic dispersion and degradation rates in marine ecosystems.
