to a study by Rutgers and other institutions.

The study appears in the journal PNAS.

New report highlights link
between air pollution and
infant mortality

PHYS.ORG 10/09/21

A [new report](https://www.phys.org/press-releases/2021/09/09/new-report-out-today-calls-for-an-urgent-collaborative-effort-to-reduce-air-pollution-around-the-globe) out today calls for an urgent collaborative effort to reduce air pollution around the globe.

The report, led by Save the Children
International, outlines the sources of air pollution,
its effects on children and young people, and
highlights the work being done to address the
issue. [...]

One of the report authors Dr. Cressida Bowyer, Deputy Lead for Revolution Plastics at the University of Portsmouth has worked with communities in the Global South, investigating the huge impact the unregulated burning of plastic waste has on air pollution. [...]

Sunlight can break down marine plastic into tens of thousands of chemical compounds

PHYS.ORG 08/09/21

[...] Scientists more recently have learned that sunlight also chemically transforms plastic into a suite of polymer-, dissolved-, and gas-phased products.

Now, a new study finds that this chemical reaction
can produce tens of thousands of water-soluble
compounds, or formulas. The breakdown into this
many formulas, in a matter of weeks, is at least
ten-fold more complex than previously
understood. [...]

First ever study finds
microplastics in northeast
Lapland

The Barents Observer 31/08/21

A research project, led by non-profit organisation Snowchange Cooperative, has found large amounts of microplastics in Näätämöjoki river and Lake Inari. The project's aim was to track the impacts of climate change in Näätämö, Vuonnijavr, Voronye and Ponoi waters, and they conducted first ever surveys on microplastics in northeast Lapland. The research has shown that the amount of microplastics in Lake Inari is similar to samples taken from lakes in Southern Finland.

Nano/microparticles in
conjunction with microalgae
extract as novel insecticides
against Mealworm beetles,
*Tenebrio molitor*

Nature 24/08/21

The intensive use of insecticides in global agricultural production has attracted much attention due to its many adverse effects on human health and the environment. In recent years, the utilization of nanotechnology has
emerged as a tool to overcome these adverse effects. The aim of this work was to test different microparticles (zinc oxide (ZnO MPs) and silicon dioxide microparticles (SiO2 MPs)), and silver nanoparticles (Ag NPs) and to study their toxicity on a model organism, *Tenebrio molitor*. A comprehensive comparative study, which included more than a thousand mealworms divided into nine separate groups, was conducted. In addition to pure nano/microparticle solutions, the effect of particles mixed with the microalgae extract *Chlamydomonas reinhardtii* was also observed. [...]
