“…In artificial and natural soils, cdmt seems to be mainly affected by the high Ag contents (Choi and Park, 2015;Hayashi et al, 2013) but in Curieses Silvana et al (2017) low (0.05 mg kg-1) and high concentrations caused this upregulation. In some cases, when the exposure lasts longer (10 14 days), downregulation of cdmt can be observed with low and medium concentrations (0.05 to 50 mg kg-1 ) in artificial soil (Bourdineaud et al, 2019;Curieses Silvana et al, 2017). In all these cited studies, the measure of relative expression levels of these 3 genes were measured during the first 2 weeks of exposure.…”

“…This nding indicates that DMP has potency to modify the protein structures via oxidative damages in earthworms. The presence of carbonyl groups in proteins has been considered as the biomarker of ROS mediated protein oxidation in earthworms exposed to certain pollutants (Bourdineaud et al 2021). The by-products of LPO, such as MDA and 4hydroxy-2-nonenal, can react with the amino groups of certain amino acids forming reactive carbonyl groups (aldehydes and ketones) that cause protein oxidation via secondary reactions leading to cell inactivation.…”

In ecotoxicological studies, oxidative damages and antioxidant defense responses in earthworms have been used as hallmarks for assessing the environmental pollution. Phthalates, which are esters of phthalic acid (PAEs) are primarily used to enhance plasticity of industrial polymers, and are an unavoidable part of modern life. In the present study, ecotoxicological effects of dimethyl phthalate (DMP) were investigated in the earthworms Lumbricus terrestris L., at different concentrations (0, 0.1, 1, 10 and 50 mg kg-1) on the 7th and 14th days of exposure in artificial soils. We evaluated the effects of DMP on oxidative stress (OS) biomarkers including malondialdehyde (MDA/LPO) level and the activities of antioxidant enzymes catalase (CAT) and glutathione S-transferase (GST), and carbonylated proteins (CP) content in earthworm’s whole body extract. The neutral red retention (NRR)-time of coelomocytes and total antioxidant capacity (TAC) were also measured in the earthworm’s coelomic fluid (ECF). Upon exposure to DMP, OS status was induced in a time and concentration-dependent manner. The MDA level, CAT and GST activities, and CP content were found to be increased, but the TAC value and NRR-times were decreased in all DMP-treated groups on 7th and 14th days of exposure. The toxicity of DMP was generally greater in the groups with 14 day toxicant exposure. Briefly, our resultes defined that DMP is a source of oxidative damages in the earthworms. However, for detailed elucidation of the mechanisms associated with DMP ecotoxicity and its adverse impacts in the soli organisms, further unraveling is needed.

“…The migrations and behaviour of these pollutants can pose environmental and human risks [10], [13][14][15] This has provoked discussions about the safety of, and potential risks associated with, nanotechnology. A strong emphasis has been placed on determining the toxicity of nanostructures to various groups of organisms, including perennials, wheat, bacteria, protozoa, macrophytes, earthworms, fish, mice and rats [16][17][18][19][20][21][22][23][24][25]. It also appears extremely important to determine the characteristics and stability of nanoparticles in order to understand how they function in aqueous solutions and interact with standard substances in the environment [1], [9][10][11][12].…”

“…Dlatego też nanotechnologia jest przedmiotem dyskusji w kontekście bezpieczeństwa i ryzyka. Duży nacisk położony jest na określenie toksyczności nanostruktur w odniesieniu do różnych grup organizmów, w tym bylin, pszenicy, bakterii, pierwotniaków, makrofitów, dżdżownic, ryb, myszy, szczurów [16][17][18][19][20][21][22][23][24][25]. Określenie cech i stabilności nanocząstek jest bardzo istotne, gdyż pozwala także zrozumieć ich funkcjonowanie w roztworach wodnych oraz w interakcji z podstawowymi substancjami obecnymi w środowisku [1], [9][10][11][12].…”

Nanocząstki metali w wodach powierzchniowych -zagrożenie dla organizmów wodnychABSTRACT Purpose: The aim of this paper is to provide information on the risks posed by metal nanoparticles released into surface waters. Introduction: Currently, the use of nanoparticles of metal and metal oxides (NPMOs) is extremely popular in various industries, and in medicine and households. Nanoparticles and nanocompounds have become significant contributors to technological progress due to their physicochemical properties such as the melting point, electrical and thermal conductivity, catalytic activity, light absorption and scattering, as well as biocompatible and bactericidal properties. These functions cause their increased performance compared to their macro counterparts. However, it should be noted that the properties of nanocomponents can create new risks to the environment and consumers. Based on existing literature, a conclusion can be drawn that metal nanoparticles are a potential threat to plant and animal organisms, and humans. It is, therefore, necessary to intensify efforts to understand the mobility, reactivity and durability of nanocomponents in various environmental components, especially in the aquatic environment, and their toxicity to organisms. Methodology: This paper is a literature review. Conclusions:The increasing use of nanosubstances, in both commercial and industrial products, has caused an increasing concentration and diversity of these substances in aquatic ecosystems. Based on the analysis of literature reports, it can be concluded that the size of nanoparticles, their structure and arrangement, as well as surface properties, are subject to constant changes in the environment as a result of their interactions with other components, and of the balances shaped by a variety of geochemical and biological factors. Numerous studies conducted in recent years in the field of nanoecotoxicology have demonstrated the existence of a risk to aquatic organisms, which could lead to their impaired development and even death. Unfortunately, the lack of a standard technique for assessing the toxicity of nanoparticles in various biological systems, such as the reproductive, respiratory, nervous and gastrointestinal systems, and the developmental stages of aquatic organisms, makes it impossible to conduct such studies in a standardised fashion. Reports of the toxicity of metal and metal oxide nanoparticles in relation to various forms of living organisms warrant in-depth investigations into how these particles function in aqueous solutions and interact with standard substances.
