Diese Nagetierbekämpfungsmittel unterliegen in der EU einer Zulassungspflicht nach Biozid-Verordnung. Im Rahmen ihrer Zulassung in Deutschland wurden Auflagen festgelegt, die ihre Verwendung sicherer, wirksamer und nachhaltiger machen. Welche Auflagen das sind, warum sie getroffen wurden sowie Antworten auf weitere häufig gestellte Fragen zur Nagetierbekämpfung erfahren Sie in diesem Dokument. Die vorliegende 4. Auflage enthält erstmals Informationen zum Nachweis von Rodentizid-Rückständen in Fischen und widmet der Rattenbekämpfung in der Kanalisation ein eigenes Kapitel.

The aim of this study was to evaluate consumers' use and understanding of biocidal products in order to identify starting points for minimising their exposure to these products and reducing possible emissions to the environment. In a case study, standardised questionnaires were used to interview consumers in 133 households in three neighbourhoods in Northern Germany, representing the urban-rural typologies in Europe: predominantly urban, intermediate and predominantly rural regions. The questions focussed on the comprehension of the term 'biocide', pest control habits, sources of information, risk perception of different product groups and possible emission reduction measures. Only 21% of the respondents understood the term 'biocide' correctly, whereas 29% thought of 'something that had to do with organic pest control', and 28% were not able to think of a possible meaning. The risk perception of biocidal products compared to plant protection products varied depending on the living conditions. In the urban neighbourhood, biocidal products were perceived as more dangerous than in the rural area. The main pests to be fought were ants, mould and fruit fly. The results of the study indicate that there is a considerable difference between the types of biocidal products that interviewees claimed to own and those that they actually did have in their households. Most notably, respondents did not realise that they owned surface disinfectants. This result indicates that consumers often seem not to be aware of using specific biocidal products. Also, this shows the limitations of collecting data on products owned with only one method, as the results from products inventories of the households deviate from the data collected in interviews. Our results show that the term 'biocide' is not fully understood by many people. To communicate possible risks of biocidal products, other terms would have to be used. Online information regarding general facts on necessary general hygiene measures and biocidal products against bacteria and insects are likely to be of highest relevance for consumers. However, risk communication for biocidal products in general is difficult because consumers are often not aware of using biocidal products. For this reason, information and awareness raising campaigns should be accompanied by further measures such as sales restrictions for specific user-groups or prohibitions of certain uses for a sustainable use of biocidal products. © 2017 Elsevier GmbH.

Until now, the discussion of exposure sources has mainly addressed cosmetic products and neglected other scented products in households. For the first time, fragrance allergens were evaluated in a complete set of detergents in households. In 131 households, we investigated the prevalence of detergents and searched their lists of ingredients for 26 fragrance allergens liable to be indicated on products according to the European Detergents Regulations. On the ingredient lists of 1447 products, these 26 fragrance substances were named almost 2000 times, most often limonene, linalool and hexyl cinnamal. Benzyl salicylate was used frequently in all-purpose cleaners. Linalool and limonene, hexyl cinnamal and butylphenyl methylpropional and citronellol and linalool co-occurred most often together in products. Fragrance allergens co-occurring together most frequently within households were eugenol, coumarin and cinnamyl alcohol. The study shows that detergents could play a relevant role for the exposure of consumers towards fragrance allergens and that they should not be underestimated as an exposure source during the exposure assessment. © 2018 Elsevier Inc.

Over the past 40 years, several hundred of these so-called disinfection by-products (DBPs) have been detected after applications of biocides used for disinfection. Due to intensive research and further development of analytical capabilities, many new DBP classes, such as iodinated DBPs (I-DBPs), halonitromethanes (HNMs), haloacetamides (HaAms), or halomethanesulfonic acids were detected worldwide in various matrices and applications. Due to the possible hazards and risks for humans and the environment, frequently occurring DBP classes, such as trihalomethanes (THM), haloacetic acids (HAA) and nitrosamines (NDMA), have already been included in many legislations and given limit values. In the European Union, biocides are assessed under the Biocidal Products Regulation 528/2012 (BPR) regarding their efficacy, potential hazards, and risks to human health and the environment. However, the available guidance for the environmental risk assessment (ERA) of DBPs remains vague. To identify knowledge gaps and to further develop the assessment scheme for the ERA of DBPs, a literature search on the multiple uses of biocides and their formation potential of DBPs was performed and the existing process for ERA was evaluated. The results show knowledge gaps on the formation of DBP in non-aqueous systems and DBP formation by non-halogen-based biocidal active substances. Based on the literature research on biocides, a possible proposal of grouping a.s. to consider their DBP formation potential is presented to simplify future ERAs. However, this also requires further research. Until then, a pragmatic approach considering the DBPs formation potential of the active substances and the identified knowledge gaps need to be established for the environmental risk assessment of DBPs in the EU. © The Author(s) 2023Veröffentlichung Not only biocidal products: Washing and cleaning agents and personal care(2018) Olsson, Oliver; Kümmerer, Klaus; Wieck, StefanieThe emission sources of biocidal active substances in households have been under discussion since these substances have been detected frequently in municipal wastewater and receiving surface water bodies. Therefore, the goal of this study was to investigate the products responsible for the emission of these substances to wastewater. We analysed the wastewater of two streets for a set of biocidal active substances. Time-proportional sampling was conducted for one week of each season during one year in each street. The 14 substances analysed with liquid chromatography coupled with tandem mass spectrometry were 1,2-benzisothiazol-3(2H)-one (BIT), C12-benzalkonium chloride, carbendazim, 5-chloro-2-methyl-2H-isothiazol-3-one (CMIT), dichlorooctylisothiazolinone (DCOIT), N,N-diethyl-meta-toluamide (DEET), diuron, icaridine, 2-octyl-2H-isothiazol-3-one (OIT), piperonyl butoxide (PBO), triclosan, tebuconazole, terbutryn and tetramethrin. Using data available from household product inventories of the two streets, we searched the lists of ingredients for the products possibly being responsible for the emissions. Except for four substances, all substances have been detected in at least 10% of the samples. Highest concentrations were measured for C12-benzalkonium chloride with an average concentration in the daily samples of 7.7ng/L in one of the streets. Next to C12-benzalkonium chloride, BIT, DEET and icaridine were detected in all samples in average concentrations above 1ng/L in at least one street. The results show that washing and cleaning agents were important sources for preservatives such as BIT and OIT, while triclosan was apparently mainly emitted through personal care products. The mosquito repelling substances DEET and icaridine were found throughout the year, with highest emissions in summer and autumn. In conclusion, the results demonstrate that the sources of biocidal active substances in municipal wastewater are complex and that measures for the prevention of the emission of biocidal active substances into the aquatic environment have to be carried out under different legislations. This has to be taken into account discussing emission reduction at the source.Veröffentlichung In search of the Holy Grail of Rodent control: step-by-step implementation of safe and sustainable-by-design principles on the example of rodenticides(2022) Hohenberger, Johannes; Friesen, Anton; Wieck, StefanieThe field of chemical rodent control has seen no major developments in the last decades, even though anticoagulant rodenticides (AR), the mainly used substances to manage mice and rats, are known environmental pollutants and candidates for substitution under the European Biocidal Products Regulation 528/2012. Moreover, recent political developments in Europe and the USA demand more safety and sustainability in the management of chemicals, reinforcing the need for environmentally friendly substances. In this concept study, we present a step-by-step approach to improve the environmental properties of rodenticides. Repurposing of existing pharmaceuticals, the use of enantiomerically pure rodenticides, or the improvement of the formulation by microencapsulation can help to alleviate environmental problems caused by AR in the short term. Modification of the chemical structures or the development of prodrugs as medium-term strategies can further improve environmental properties of existing compounds. Ultimately, the development of new substances from scratch enables the utilisation of so far ignored modes of actions and the application of modern safe and sustainable-by-design principles to improve target specificity and reduce the negative impact on non-target organisms and the environment. Overall, our concept study illustrates the great potential for improvement in the field of chemical rodent control when applying available techniques of green and sustainable chemistry to known or potential rodenticides. Most promising in the medium term is microencapsulation that would allow for the use of acutely acting substances as it could circumvent bait shyness. On a longer timescale the de novo design of new rodenticides, which is the only method that can combine a high target specificity with good environmental properties, is the most promising approach. © 2022 The AuthorsVeröffentlichung Vom Winde verweht - Untersuchungen zur Abdrift bei der Ausbringung von Bioziden(2019) Loskyll, Julia; Wieck, Stefanie
