Ecotoxicology is an interdisciplinary field that draws from knowledge and techniques in the fields of ecology and toxicology to study the effects of toxic chemical or biological agents on biological organisms at the population, community or ecosystem level.
The widespread occurrence of microscopic plastic particles in the ocean is of both and ecological and societal concern. Here, the authors review the biological impacts of interactions with microplastics in the marine environment.
Variations in silver isotope ratio identified using inductively coupled plasma mass spectrometry offers insights into the natural transformation processes of silver nanoparticles in the environment; the approach could potentially be used to distinguish engineered silver nanoparticles from those formed naturally.
