Abstract Microplastics have been detected in large numbers around the world. Not only their sheer number threatens ecosystems, biodiversity, and human health, but risks are also posed by particle characteristics such as size shape. However, at moment measurement is neither comprehensive nor harmonized, making data ineligible for risk assessment. To change this, we propose an image-based workflow, whose six steps oriented to international guidelines lessons learned from more developed research fields. Best practices sample preparation, image acquisition, digital processing reviewed assure accurate unbiased measurements. On behalf of selected metrics quantitatively characterize both The microplastics should be estimated via maximum Feret’s diameter. Particle shape can measured descriptors, which derive harmonized formulas interpretation. Roundness , solidity elongation were applying hierarchical agglomerative clustering correlation analysis. With these three all currently charaterizable dimensions measured. Finally, present actions quality control well assurance give recommendations method documentation reporting. By our practical primer, microplastic researchers capable providing informative comparable on characteristics. From this improved data, expect see great progress assessment, meta-analyses, theory testing, fate modeling microplastics.

The presence of biodegradable microplastics (MPs) has the potential to affect soil pH, and possibly accelerate or inhibit loss inorganic carbon (SIC) in calcareous soils. However, most researchers have focused on release biotic dioxide (CO2) from soils following MP amendments, few studies investigated SIC-derived CO2. In this experiment, three typical MPs were applied amended with 1 % 13C-labeled (99 atom) carbonate, CO2 originating SIC was quantified. total emissions, microbial functional genes involved nitrification denitrification also detected. Throughout contribution carbonate emissions ranged 0.42 3.31 %. impact varied incubation period. At early stage (≤20 days), amendment increased abiotic some cases, positively correlated decomposition SOC MPs. late (20–70 inhibited treatments. Moreover, there negative relationships pH amoA gene ammonia-oxidizing archaea (AOA), but positive correlations ammonia oxidizing bacteria (AOB) nirK nirS encoding nitrate reductase denitrification. Our results indicate that long-term exposure probably regulates H+ process by controlling AOB, then dynamics
