We conducted a microcosm assay with varying concentrations (0–25 μg L-1) of small (100 nm; SNPPs) and large (1000 nm; LNPPs) plastic particles to assess their impact on leaf litter decomposition, sporulation rates and community structure of aquatic hyphomycetes. Furthermore, leaf ...
Plastic can reach the sea directly as micro-or nano - range items intentionally produced for humans (primary microplastics (MPs); primary nanoplastics (NPs) or otherwise, as big pieces that, in the environment, undergo a decomposition process that can break down their bonds forming smaller sizes...

The effect of H2O2could also be seen on the epoxy layer that we used to immobilise the particle on the Si wafers. Increased brightness and haziness of the image background was apparent especially around the wafer edges, which made more encroachments by manual image postprocessing necessary in...
The latter involves a flow of gases, vital in the decomposition of organic matter; in addition, porosity affects the proper introduction and evaporation of water (affecting the nutrition of plants, animals, and microorganisms) [80,84,85], as well as the natural flow of oxygen. These aspects ...
Furthermore, NPs can be produced in the environment by the gradual decomposition of MPs and bigger plastic particles. Thus, we propose that NPs’ high surface area and lengthy durations of exposure to abiotic or biotic variables may imply a greater vulnerability to aging or weathering processes, ...
Thermal decomposition was controlled in a Frontier Laboratories EGA/PY-3030D pyrolysis system. Molecular fragments, carried in helium (1.0 mL/minute) along a Frontier Ultra Alloy 5 UA5-30 M-0.25F + Vent free column, were separated using an Agilent Technologies 6890N chromatograph. Ion ...
In addition to growing concerns about plastic litter, tiny plastic fragments have become another major concern as they have been ubiquitously detected and can come into contact with the human body through exposure from air, water and food. Such plastic fragments are called nano- and microplastics ...
Like MPs, the sources of NPs in environment can be categorized as either primary or secondary, depending upon whether they are <1000 nm before entering the natural environment, or become this size via the degradation and fragmentation of larger pieces of plastic litter or MPs, respectively. The...
Nanoplastics (NPs) are a rapidly developing subject that is relevant in environmental and food research, as well as in human toxicity, among other fields. NPs have recently been recognized as one of the least studied types of marine litter, but potentially one of the most hazardous. Several st...
