Particulate Mercury and Particulate Organic Matter in the Itenez Basin (Bolivia) [PDF]
Applied Sciences, 2020 In rivers and other freshwater bodies, the presence of mercury can be due to direct contamination by anthropic activities such as gold mining. However, it can also be attributed to atmospheric deposition and erosion, runoff, or lixiviation from surrounding soils.

The route to protein aggregate superstructures: Particulates and amyloid‐like spherulites
FEBS Letters, 2015 Depending on external conditions, native proteins may change their structure and undergo different association routes leading to a large scale polymorphism of the aggregates. This feature has been widely observed but is not fully understood yet.
