Abstract:

Microplastics can be present in the environment as
manufactured microplastics (known as primary microplastics) or resulting
from the continuous weathering of plastic litter, which yields
progressively smaller plastic fragments (known as secondary
microplastics). Herein, we discuss the numerous issues associated with
the analysis of microplastics, and to a less extent of nanoplastics, in
environmental samples (water, sediments, and biological tissues), from
their sampling and sample handling to their identification and
quantification. The analytical quality control and quality assurance
associated with the validation of analytical methods and use of
reference materials for the quantification of microplastics are also
discussed, as well as the current challenges within this field of
research and possible routes to overcome such limitations.

Airborne microplastics: Consequences to human health?,

Environmental Pollution, Volume 234, 2018, Pages 115-126, ISSN 0269-7491,

Abstract:

Microplastics have recently been detected in atmospheric fallout in Greater Paris. Due to their small size, they can be inhaled and may induce lesions in the respiratory system dependent on individual susceptibility and particle properties.
Even though airborne microplastics are a new topic, several observational studies have reported the inhalation of plastic fibers and particles, especially in exposed workers, often coursing with dyspnea caused by airway and
interstitial inflammatory responses. Even though environmental concentrations are low, susceptible individuals may be at risk of developing similar lesions.
To better understand airborne microplastics risk to human health, this work summarizes current knowledge with the
intention of developing awareness and future research in this area.

Abstract:

With the large amount of attention being given to microplastics in the environment,
several researchers have begun to consider the fragmentation of plastics down
to lower scales (i.e., the sub-micrometer scale). The term “nanoplastics” is still under debate,
and different studies have set the upper size limit at either 1000 nm or
100 nm. The aim of the present work is to propose a definition of
nanoplastics, based on our recently published and unpublished research
definition of nanoplastics. We define nanoplastics as particles
unintentionally produced (i.e. from the degradation and the
manufacturing of the plastic objects) and presenting a colloidal
behavior, within the size range from 1 to 1000 nm.
