Sewage sludge application on soils represents an important potential source of silver nanoparticles (Ag NPs) to terrestrial ecosystems, and it is thus important to understand the fate of Ag NPs once in contact with soil components. Our aim was to compare the behavior of three different forms of silver, namely silver nitrate, citrate stabilized Ag N...
Nanoremediation with iron (Fe) nanomaterials opens new doors for treating contaminated soil and groundwater, but is also accompanied by new potential risks as large quantities of engineered nanomaterials are introduced into the environment. In this study, we have assessed the ecotoxicity of four engineered Fe nanomaterials, specifically, Nano-Goeth...
We investigated dissipation, earthworm and plant accumulation of organic contaminants in soil amended with three types of sewage sludge in the presence and absence of plants. After 3 months, soil, plants and earthworms were analyzed for their content of organic contaminants. The results showed that the presence of plant roots did not affect dissipa...
While tire wear and tear is known to be a major source of microplastics in the environment, its monitoring is still hampered by the lack of analytical methods able to provide concentrations in environmental matrices. Tire wear particles (TWP) present in road runoff enter the drainage system through gully pots, built to prevent sediment deposition i...
Plastic pollution is a widespread environmental problem that is currently
one of the most discussed issues by scientists, policymakers and society at large.
The potential ecotoxicological effects of plastic particles in a wide range of organisms
have been investigated in a growing number of exposure studies over the past
years. Nonetheless, many qu...
Motorsport is known for its high tire wear due to speed, cornering, and high acceleration/deceleration activities. However, studies on the generation of microplastics from racetracks are rare. This study aimed at quantifying microplastics concentrations in topsoil (0–5 cm) along a racetrack. The results showed that rubber materials (RM) and tire re...
Ongoing efforts focus on quantifying plastic pollution and describing and estimating the related magnitude of exposure and impacts on human and environmental health. Data gathered during such work usually follows a receptor perspective. However, Life Cycle Assessment (LCA) represents an emitter perspective. This study examines existing data gatheri...
Bioretention cells are popular stormwater management systems for controlling peak runoff and improving runoff water quality. A case study on a functional large-scale bioretention cell and a laboratory column experiment was conducted to evaluate the concentrations and retention efficiency of bioretention cells towards tire wear particles (TWP). The...
Biogas digestate is a nitrogen (N) rich waste product that has potential for application to soil as a fertiliser. Composting of digestate is recognized as an effective step to reduce potentially negative consequences of digestate application to soils. However, the structure of the digestate and the high N content can hinder effective composting. Bi...
Large amounts of tire crumb, up to several kg per m2, are found in soil near the artificial turf fields at Hosle, Nadderud and Føyka, Norway.
In this study, the effects of aged Ag and TiO2 NPs, individually and as a mixture, in wastewater relative to their pristine counterparts on the development of the copepod nauplii (Tisbe battagliai) were investigated. NP behavior in synthetic wastewater and seawater was characterized during aging and exposure. A delayed development and subsequent mo...
The current study provides an in vivo analysis of the production of reactive oxygen species (ROS) and oxidative stress in the nematode Caenorhabditis elegans following exposure to EU reference silver nanoparticles NM300K and AgNO3. Induction of antioxidant defenses was measured through the application of a SOD-1 reporter, and the HyPer and GRX bios...
Remediation using nanoparticles depends on proper documentation of safety aspects, one of which is their ecotoxicology. Ecotoxicology of nanoparticles has some special features; while traditional ecotoxicology aims at measuring possible negative effects of more or less soluble chemicals or dissolved elements, nanoecotoxicology aims at measuring the...
Using Caenorhabditis elegans as a model organism, this study addresses the potential linkage between toxicity of NM300K Ag nanoparticles (AgNPs), their particle size distribution and the presence of dissolved Ag in the test media. Of the three endpoints assessed (growth, fertility and reproduction), reproduction was the most sensitive, with 50% eff...
Understanding how toxic contaminants affect wildlife species at various levels of biological organization (subcellular, histological, physiological, organism, and population levels) is a major research goal in both ecotoxicology and radioecology. A mechanistic understanding of the links between different observed perturbations is necessary to predi...
Welcome to the final conference of the COST Action ES1205. The most important aim of our Action was to create a pan-European network and, glancing at the book of abstracts – I can say – we were successful. The majority of contributions you will find here were influenced by our activities. The foundations of this Action however, must certainly be th...
Sewage sludge is an important amendment that enriches soils with organic matter and provides plants with nutrients such as nitrogen and phosphorus. However, knowledge on fate and effects of organic pollutants present in the sludge on soil organisms is limited. In the present study, the uptake of triclosan, galaxolide, and tonalide in the earthworm...
Nonylphenols (NP) are a group of alkylphenols, formed upon degradation of nonylphenol ethoxylates such as nonylphenol monoethoxylate (NP1EO) or nonylphenol diethoxylate (NP2EO), which have been broadly used as non-ionic surfactants. Both NP and their ethoxylates are often present in the sewage, despite being banned and substituted by less toxic alc...
Samples from the large scale experiments and from four field sites (Spolchemie sites I and II in Ustí
nad Labem, CZ; Solvay site, CH; Balassagyarmat, HU) were analysed for their potential toxicity (Task
5.3 Time‐course of ecotoxicity alleviation after interactions with soil constituents) and their microbial
community composition (Task 5.4 NP‐microb...
In times where we need to reduce our CO2 emissions to the atmosphere, it is important to get a clearer picture of the environmental impacts associated with potential mitigation technologies. Chemical absorption with amines is emerging as the most advanced mitigation technology for post-combustion capture of CO2 from fossil fuel power stations. Alth...
As innovation in remediation technology brings new solutions to old problems, regulatory bodies
require hazard and safety data as new technologies are brought from lab‐scale to real‐world application.
NanoRem has therefore a full work package dedicated to measuring the environmental impact
of the nanoparticles used in the project. This is important...
The IAEA is currently preparing a new Technical Reports Series (TRS) Handbook on the Transfer of Radionuclides to Wildlife. Key deficiencies have been identified and one is the lack of data for birds. In this study we measured the transfer of a range of elements measured by neutron activation analysis (NAA) and gamma analysis in four Barn owls (Tyt...

Due to difficulties in tracing engineered nanoparticles (ENPs) in complex media, there are few data on the exposure of soil biota to ENPs. This study used neutron activated cobalt (Co NPs) and silver (Ag NPs) nanoparticles, as well as soluble cobalt and silver salts, to assess the uptake, excretion and biodistribution in the earthworm Eisenia fetid...
Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity. The aim of this study was to examine whether the effects of a herbicide mixture (50% atrazine, 35% isoproturon, 15% al...

The project aims to create new knowledge on degradability and potential for unintentional spread and accumulation in the environment of biodegradable and compostable plastic materials, which are currently used or likely to see increased use in Norway.
Further, it aims to determine the extent to which the use of biodegradable and compostable plastics challenges sustainability considerations, when interference with recycling of conventional plastics, littering and spread of non-degraded residues, consumer behaviour, materials and resource use, are considered for the society at large.
Three main research areas will be developed during the project, the first on degradation of biodegradable mulch films in soils under Nordic conditions, the second on fate of biodegradable and compostable plastic materials in waste streams, and the third providing a life-cycle perspective on biodegradable plastic materials in both agriculture and waste streams.
