TL;DR: This study studied the survival and fitness of the earthworm Lumbricus terrestris exposed to microplastics in litter at concentrations of 7, 28, 45, and 60% dry weight, percentages that, after bioturbation, translate to 0.2 to 1.2% in bulk soil.

TL;DR: In this article, the authors present a concept that shows the current state of art and challenges for monitoring programs, fate and risk assessment tools and requirements for policies with respect to emerging pollutants as a base for sustainable water resource management.

TL;DR: The data show that micro- and macroplastic are capable of entering terrestrial food webs and were found in traditional Mayan home gardens in Southeast Mexico where waste mismanagement is common.

TL;DR: In this article, a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts is described. But despite the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work.

TL;DR: The high biogenic incorporation rate of the small-fraction microplastics from surface litter into burrow walls causes a risk of leaching through preferential flow into groundwater bodies, which may have implications for the subsequent availability of microplastic to terrestrial organisms or for the transport of plastic-associated organic contaminants in soil.
