Manure is widely used as a fertilizer and applied to agricultural land. It may contain highly active chemicals like veterinary medicinal products or biocides, which enter the environment by this pathway. This is recognized by several regulatory frameworks, however, a detailed method for examining the transformation of chemicals in manure was lacking. The present publication […]
On 30 June 2022, the OECD published test guideline No. 320: ‘Determining anaerobic transformation of chemicals in liquid manure’. This guideline describes a standardised method to investigate transformation of chemical substances in pig and cattle liquid manure under anaerobic conditions. The experiments are performed to determine the rate of transformation of the test substance, the […]
A proposal was prepared for the post-authorisation monitoring of veterinary medicinal products, in particular parasiticides. Such a monitoring might especially be useful for parasiticides identified as PBT substances, i.e., substances that are toxic (T), persist in the environment (P) and bioaccumulate (B). Based on a literature search, issues are discussed that have to be considered […]
The 16th International Waste Management and Landfill Symposium takes place in Forte Village, Santa Margherita di Pula (Sardinia, Italy) from 2 to 6 October 2017. ECT is contributing with the following platform presentation: J. Römbke: Testing of 24 potentially hazardous wastes using ecotoxicological tests For further information on the International Waste Management and Landfill Symposium […]
The 12th Biennial Meeting of SETAC Latin America (‘Bridging the gap between science and governance’) takes place in Santos, São Paulo, Brazil, from 7 to 10 September 2017. ECT is contributing with the following two platform presentations: J. Römbke, J. Bernard: The TRIAD – a new ISO standard for retrospective risk assessment in soil (ISO […]
Veterinary medicinal products administered to animals are excreted with urine and faeces. For animals housed in stables, the resulting manure is collected and stored before being spread onto agricultural land. Disinfection products used to sanitize stables are also transferred into the manure. Therefore, the spreading of manure is an important pathway of introducing veterinary medicines, […]
Avermectin and milbemycin parasiticides have a high toxicity to non-target organisms, are often persistent and may have a potential to bioaccumulate. The present project contributes to filling gaps in the database for a complete environmental risk assessment of these parasiticides. In addition, risk management strategies for parasiticides used in pasture animals were discussed. For ivermectin […]
The environmental risks related to human and veterinary pharmaceuticals have to be assessed according to legal requirements within the authorisation procedures for pharmaceuticals. If a risk for the environment is indicated, risk mitigation measures should be proposed by the applicant and implemented within the risk management. The authorisation of a veterinary pharmaceutical can be refused […]
The aims of this project were the compilation and publication of the results of workshops with international dung fauna experts (Aveiro group) and the further improvement of existing laboratory tests with dung beetles and dung flies. Two publications were prepared: first, recommendations for the preparation, performance and assessment of field studies with dung organisms, and […]
The most likely entry pathways of veterinary medicinal products (VMPs) into the environment are via slurry or manure from intensively reared animals to soil, and via dung or urine from animals grazing on pasture. Surface water may be contaminated via run-off or leaching and drainage, or by direct excretion of pasture animals into water. According […]
