Plastic bans in India – Addressing the socio-economic and environmental complexities
(Peer reviewed; Journal article, 2023)As one of the flagship amendments to the Plastic Waste Management (PWM) Rules, 2021, the pan-Indian ban on a group of single-use plastic products (SUPPs) introduced in mid-2022 provided a departure point towards more ... -
Plastic ingestion by Atlantic cod (Gadus morhua) from the Norwegian coast
(Journal article; Peer reviewed, 2016)This study documents the occurrence of microplastic (< 5 mm), mesoplastics (5–20 mm) and macroplastic (> 20 mm) in Atlantic cod (Gadus morhua), a common and economically important species of marine fish in Norway. Fish ... -
Plastic pollution in Indonesia and the Philippines: current status and upcoming knowledge needs
(NIVA-rapport;7662, Research report, 2021)Research on plastic leakage and marine debris has developed significantly the last few years, but our knowledge on the scope of the problem, environmental and societal effects, and potential solutions is still limited. ... -
Plastic recycling plant as a point source of microplastics to sediment and macroinvertebrates in a remote stream
(Journal article; Peer reviewed, 2022)Microplastic is now ubiquitous in freshwater, sediment and biota, globally. This is as a consequence of inputs from, for example, waste mismanagement, effluents from wastewater treatment plants and surface runoff from ... -
Plastic sources: A survey across scientific and grey literature for their inventory and relative contribution to microplastics pollution in natural environments, with an emphasis on surface water
(Journal article; Peer reviewed, 2019)Plastic debris are at present recognized as an emerging potential threat for natural environments, wildlife and humans. In the past years an increasing attention has been addressed to investigate the presence and concentration ... -
Plastics in biosolids from 1950 to 2016: A function of global plastic production and consumption
(Peer reviewed; Journal article, 2021)Plastics are ubiquitous contaminants that leak into the environment from multiple pathways including the use of treated sewage sludge (biosolids). Seven common plastics (polymers) were quantified in the solid fraction of ... -
Plastid DNA sequences and oospore characters of some European taxa of Tolypella section Tolypella (Characeae) identify five clusters, including one new cryptic Tolypella taxon from Sardinia, but they do not coincide with current morphological descriptions
