    In vitro characterization of cutaneous immunotoxicity of immortalized human keratinocytes (HaCaT) exposed to reactive and disperse textile dyes
    (2018) Leme, Daniela Morais; Grummt, Tamara; Sehr, Andrea
    Several synthetic dyes are used by textile industry for supplying the market of colored clothes. However, these chemicals have been associated with a variety of adverse human health effects, including textile dermatitis. Thus, there is a growing concern to identify textile dyes potentially as skin immunotoxicants. The aim of this in vitro study was to characterize the immunotoxic potential of reactive (Reactive Green 19 [RG19], Reactive Blue 2 [RB2], Reactive Black 5 [RB5]) and disperse (Disperse Red 1 [DR1]) textile dyes using a dermal cell line. For this purpose, a cell-based approach was conducted with immortalized human keratinocytes (KC) (HaCaT) using selected biomarkers of cutaneous inflammation including modulation of matrix metalloproteinases (MMP), oxidative stress such as reactive oxygen species (ROS) generation, and inflammatory cytokine profile. DR1 was the only dye able to trigger an immune response such as release of IL-12 cytokine, a potent co-stimulator of T helper 1 cell, which may be considered as a skin immunotoxicant. The reactive dyes including RB5 that were previously reported as skin sensitizers failed to induce inflammatory reactions under the conditions tested. The reactive dyes studied may pose a risk to human KC by induction of effects related to modulation of MMP-2 (RB5) and -9 (RB5 and RB2) and generation of ROS (RG19 and RB2). Thus, all these dyes need to be used with caution to avoid undesirable effects to consumers who may be exposed dermally. Quelle: https://www.tandfonline.com

    Chemicals and cell-based assays in drinking water sources in Manhiça, Mozambique
    (2021) Villanueva, Cristina M.; Grau-Pujol, Berta; Evlampidou, Iro; Grummt, Tamara; Kuckelkorn, Jochen
    Background The chemical quality of drinking water is widely unknown in low-income countries. Objective We conducted an exploratory study in Manhiça district (Mozambique) to evaluate drinking water quality using chemical analyses and cell-based assays. Methods We measured nitrate, fluoride, metals, pesticides, disinfection by-products, and industrial organochlorinated chemicals, and conducted the bioassays Ames test for mutagenicity, micronuclei assay (MN-FACS), ER-CALUX, and antiAR-CALUX in 20 water samples from protected and unprotected sources. Results Nitrate was present in all samples (median 7.5†mg/L). Manganese, cobalt, chromium, aluminium, and barium were present in 90-100% of the samples, with median values of 32, 0.6, 2.0, 61, 250†(mirco)g/l, respectively. Manganese was above 50†ÎÌg/l (EU guideline) in eight samples. Arsenic, lead, nickel, iron, and selenium median values were below the quantification limit. Antimony, cadmium, copper, mercury, zinc and silver were not present. Trihalomethanes, haloacetic acids, haloacetonitriles and haloketones were present in 5-28% samples at levels

    Environmental aspects have so far only partially been addressed in the discussion of antimicrobial resistance. To bring this issue into focus, ⁠UBA⁠ compiled background information and data on the topic 'Antibiotics and antimicrobial resistance in the environment'. The results show that previously considered requirements for reduction, from the perspective of UBA, are insufficient to adequately protect health and the environment. UBA sees urgent need for improvement and proposes possible options for action.

    Mikroplastik im Wasserkreislauf
    (Universitätsverlag der TU Berlin, 2020) Jekel, Martin; Anger, Philipp; Bannick, Claus Gerhard; Barthel, Anne-Kathrin; Grummt, Tamara; Kuckelkorn, Jochen; Obermaier, Nathan; Ruhl, Aki Sebastian; Strobel, Claudia; Technische Universität Berlin.

    Das interdisziplinäre Forschungsprojekt MiWa widmete sich grundlegenden Fragestellungen zur Analytik und Wirkung von Mikroplastik-Partikeln im Wasserkreislauf. Es wurden Methoden der Umweltprobennahme, der Probenaufbereitung und verschiedene Detektionsverfahren zur Charakterisierung und Quantifizierung von Mikroplastik intensiv untersucht, miteinander verglichen und weiterentwickelt. Öko- und humantoxikologische Untersuchungen dienten dem Zweck, die potenziell von Mikroplastik ausgehende Gefährdung für die aquatische Umwelt und den Menschen zu analysieren und zu bewerten. Eine Harmonisierung und Standardisierung von Methoden der Probennahme, Probenaufbereitung und Mikroplastik-Detektion sind trotz der erheblichen Fortschritte derzeit nur teilweise möglich. Die ökotoxikologischen Studien zeigen zwar die Aufnahme von Mikroplastik-Partikeln durch einige Organismen, jedoch konnte bisher keine schädigende Wirkung nachgewiesen werden. Dabei wurden für eine Auswahl aquatischer Modellspezies sowohl Szenarien direkter als auch indirekter Exposition innerhalb einer Nahrungskette betrachtet. Interaktionen mit menschlichen Modellzellen wurden bislang nur bei Mikroplastik-Partikeln mit Größen weit unterhalb von 1 Ìm (also Nanoplastik) beobachtet. Eine umfassende Bewertung ist bislang nicht möglich. Quelle: https://depositonce.tu-berlin.de

    Effect-based evaluation of ozone treatment for removal of micropollutants and their transformation products in waste water
    (2021) Dopp, Elke; Pannekens, Helena; Gottschlich, Anne; Grummt, Tamara
    The aim of this interdisciplinary research project in North Rhine-Westphalia (NRW), Germany, entitled "Elimination of pharmaceuticals and organic micropollutants from waste water" involved the conception of cost-effective and innovative waste-water cleaning methods. In this project in vitro assays, in vivo assays and chemical analyses were performed on three municipal waste-water treatment plants (WWTP). This publication focuses on the study of the in vitro bioassays. Cytotoxic, estrogenic, genotoxic and mutagenic effects of the original as well as enriched water samples were monitored before and after wastewater treatment steps using MTT and PAN I, ER Calux and A-YES, micronucleus and Comet assays as well as AMES test. In most cases, the measured effects were reduced after ozonation, but in general, the biological response depended upon the water composition of the WWTP, in particular on the formed by-products and concentration of micropollutants. In order to be able to assess the genotoxic and/or mutagenic potential of waste-water samples using bioassays like Ames test, Comet assay or micronucleus test an enrichment of the water sample via solid-phase extraction is recommended. This is in agreement with previous studies such as the "ToxBox"-Project of the Environmental Agency in Germany. © 2022 Informa UK Limited
