“…While society depends on water resources, anthropogenic activities have compromised the quality of these resources and related environmental systems. For instance, sea-level rise is threatening groundwater reservoirs (Rotzoll and Fletcher, 2013), and all parts of the water cycle are contaminated by pollutants such as plastic (Liu et al, 2020;van Emmerik and Schwarz, 2020), bilge water (Tiselius and Magnusson, 2017), nutrients (Lintern et al, 2020), pesticides (Payraudeau and Gregoire, 2012), road salt (Szklarek et al, 2022), and oil (Lucas and MacGregor, 2006).…”

This paper shares an Early-Career Scientist (ECS) perspective on potential themes for the upcoming International Association of Hydrological Sciences (IAHS) scientific decade (SD). Six discussion sessions were organised in four countries in western Europe in spring 2022. Early-career hydrologists were invited to join the sessions to formulate potential SD themes, to provide feedback on themes proposed in earlier sessions, and to further develop the proposed themes. This community paper summarizes the outcome of these discussion sessions, where three potential themes were identified that could serve to direct the broader hydrological community: “Tipping points and thresholds in hydrology”, “Intensification of the water cycle”, and “Water services under pressure”. Additionally, four trends were distinguished concerning the way in which hydrological research is conducted: big data, bridging science and practice, open science, and inter- and multidisciplinarity. These themes and trends can provide valuable input for future discussions on the theme for the next IAHS SD and they can also serve as a guidance for future research pathways.

“…Plants can intercept MPs carried by winds and rains, and rough surfaces such as stems, leaves, owers, and fruits can absorb microplastics (estimated 0.13 trillion MPs/cm² (Liu et al, 2020) and be internalized 61 . Thus, contaminating frugivorous species, with bats from the subfamily Carollinae, Rhinolophynae, and Stenodermatinae, feed on mature fruits and oral parts still on the mother plant 13 .…”

This study shows the abundance of contamination by plastic microfibers (PMs) and the first record of contamination by PMs in bats. Additionally, we tried to understand the mechanism of the environmental contamination of bats. Therefore, the digestive and respiratory tracts of 25 species of adult bats were extracted for analysis. Bats were captured in different locations in the Brazilian Amazon (Altamira, Bragança, Brasil Novo, Medicilândia, Nova Timboteua, Placas, Uruará and Vitória do Xingu, all in the state of Pará). The results showed that all species were contaminated with PMs in at least one of the analyzed systems. For the digestive system, the form of contamination occurs through bioaccumulation and biomagnification by the ingestion of contaminated food or water. While for the respiratory system, contamination occurs through the inhalation of PMs suspended in the atmospheric air. The different foraging characteristics of bats, the type of capture strategy for this food, and the type of habitat reinforce the idea that plastic contaminants are present in all environments.

Liu et al [27] stated that dam construction also exerted a notable alteration on microplastics abundance by reducing the flow velocity through water impoundment. Thus, microplastics from upstream will be accumulated right behind the dam and reduce the chances to flow to the downstream [28].…”

Microplastics pollution has become a worldwide common problem. Despite the growing numbers in researches regarding the microplastics, the understanding of microplastics in the freshwater environment are still less. This paper overviews the present knowledge and findings on the occurrence of microplastics in water and sediment of the freshwater environments in Asia. The review also covers the size distribution, polymers, morphological characteristics and sources of microplastics to the freshwater systems. Perspective of the adsorption of heavy metals on the microplastics to the freshwater systems are also discussed in this review.
