- Microplastics (MPs) are a significant environmental concern due to their ability to absorb heavy metals like lead (Pb) and copper (Cu), which can harm aquatic life and human health.
- This study examines how the size and aging of MP types (polystyrene and polypropylene) affect their capacity to adsorb these heavy metals, finding that smaller and older MPs are more effective adsorbents.
- Various environmental factors, such as pH and temperature, influence the adsorption processes, with electrostatic interactions and surface characteristics playing key roles in the binding of heavy metal ions to the microplastics.
Background: Since late 2019, the global community has been gripped by the uncertainty surrounding the SARS-CoV-2 pandemic. In November 2021, the emergence of the Omicron variant in South Africa added a new dimension. This study aims to assess the disease's severity and determine the extent to which vaccinations contribute to reducing mortality rates.

The current study looked into how weathered polyethylene (wPE) MPs affected Danio albolineatus immunological and haematological markers. In this experiment, fish of both sexes were placed in control and exposure groups, and they were exposed for 40 d at the sublethal level (1 μg L) of fragmented wPE, which contained 1074 ± 52 MPs per litre.

Microsampling, the process of obtaining small amounts of blood, has thus gained popularity as it offers minimal-invasiveness, reduced logistical costs and biohazard risks while simultaneously showing increased sample stability and a potential for the decentralization of the approach and at-home self-sampling. Although the benefits of microsampling have been recognised, its adoption in clinical practice has been slow.
