Microplastics in Invasive Freshwater Mussels (Dreissena sp.): Spatiotemporal Variation and Occurrence With Chemical Contaminants

Frontiers in Marine Science, 2021
Invasive zebra and quagga mussels (Dreissena spp.) in the Great Lakes of North America are biomonitors for chemical contaminants, but are also exposed to microplastics (<5 mm).

Polystyrene microplastics alter bioaccumulation, and physiological and histopathological toxicities of cadmium in the polychaete Perinereis aibuhitensis

Frontiers in Marine Science, 2022
Heavy metal (HM) pollution in the marine environment has been of concern for decades. The potential impact of HMs carried by emerging marine pollutants such as microplastics (MPs) has attracted attention only in recent years.

Satellite laser ranging at ultra-high PRF of hundreds of kilohertz all day

Frontiers in Physics, 2022
Satellite laser ranging (SLR) had been operated at a pulse repetition frequency (PRF) from ∼10 Hz to 10 kHz; the ultra-high PRF of SLR (UH-SLR) is a trend of development.

Plastic debris in lakes and reservoirs [PDF]

Nature, 2023
Plastic debris is thought to be widespread in freshwater ecosystems globally1. However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging2,3. Here we present a standardized cross-national survey that assesses the abundance and type of plastic debris (>250 μm) in freshwater ecosystems.

Sorting Debris

CoSMO, 2023
Thinking about modernist urbanism as a period in architecture with potential for the future of cities has been outside the canon for several decades. But from a critical viewpoint, the postmodern stance on modernist mass housing continuously failed to dissociate high modernist urbanism as a unified architectural project from its socio-political ...
