Forensic determination of adhesive vinyl microplastics in urban soils.

Article Synopsis
- Plastic production is mainly happening in urban areas, leading to soil contamination with plastic fragments, especially from adhesive vinyl used in signage.
- This study is the first to examine how weathered adhesive vinyl can break down into microplastics in urban soils, revealing significant concentrations of microplastics in soil samples taken from around a sign exposed for eight years.
- The findings highlight the need for more sustainable materials in urban signage and suggest this research can aid in developing public policies on plastic pollution and improve controls on polluting companies.
Rethinking the effects of micro/nanoplastics from the global environmental change and systematic perspective: An aquatic environmental system-based comprehensive assessment approach of micro/nanoplastic impacts.

Canadian Light Source, Saskatoon, Saskatchewan S7N 2V3, Canada.
The study on micro/nanoplastic pollution should embrace complexity. Here, we aim to develop an aquatic environmental system-based comprehensive assessment approach of micro/nanoplastic impacts (ACAM) to evaluate the effects of micro/nanoplastics on aquatic ecosystems from the global environmental change (GEC) and systematic perspective. A case study for freshwater systems in Saskatchewan, Canada was conducted to evaluate the comprehensive effects of multiple GEC factors (polystyrene-nanoplastics (PS-NPs), N, P, salinity, dissolved organic matter (DOM), pH, hardness) on Asterococcus superbus based on ten ecologically relevant endpoints.

Article Synopsis
- The study investigates how microplastics move through the Boulder Creek and its tributary, South Boulder Creek, focusing on the influence of urbanization and water management practices.
- It found that Boulder Creek, being more urbanized, had higher concentrations of microplastics in both water and sediments compared to the less urbanized South Boulder Creek.
- Flow diversions in the river removed over 500 microplastic particles per second, indicating these management practices significantly affect microplastic distribution and should be included in models assessing plastic pollution entering the oceans.
Rethinking plastic recycling: A comparison between North America and Europe.

Department of Biosystems Engineering, University of Manitoba, Winnipeg, Manitoba, Canada. Electronic address:
In this article, we identify the problem of plastic proliferation, the consequent expansion of plastic waste in our society, the inadequacies of current attempts to recycle plastic, and the urgency to address this problem in the light of the microplastic threat. It details the problems with current efforts to recycle plastic and the particularly poor recycling rates in North America (NA) when compared to certain countries in the European Union (EU). The obstacles to plastic recycling are overlapping economic, physical and regulatory problems spanning fluctuating resale market prices, residue and polymer contamination and offshore export which often circumvents the entire process.

Given the increasing amounts of plastic debris entering marine and freshwater ecosystems, there is a growing demand for environmentally relevant exposure scenarios to improve the risk assessment of microplastic particles (MPs) in aquatic environments. So far, data on adverse effects in aquatic organisms induced by naturally exposed MPs are scarce and controversially discussed. As a consequence, we investigated the potential role of MPs regarding the sorption and transfer of environmental contaminants under natural conditions.
