Title: Investigating reproductive toxicity using non experimental animal models
There are more than 300 000 synthetic chemicals and mixtures in commerce worldwide. The relative few that have been evaluated for safety were tested by a system that is known to be both slow, expensive and insensitive to certain kinds of toxicity. There are major currently ongoing efforts to update the testing system, to make it more protective of public health and to require the use of fewer animals in toxicity testing. In this talk, I will talk about non- experimental animal models to investigate chemical toxicity, specifically focusing on reproductive toxicity. I will give examples on previous and ongoing research using bovines and pet animals to study endpoints of reproductive toxicity.
Speaker: Prof. Asta Tvarijonaviciute, Murcia University (Spain), and Assoc. Prof. Jana Weiss, Dept. Environmental Science, Stockholm University
Title: Using saliva as a novel non-invasive sampling matrix – the dog pilot on synthetic phenolic antioxidants
There is a need to establish easily accessible non-invasive sampling methods, which would enable society-based research and encourages study objects to participate, with as little as possible interventions with their beloved pets. Saliva could be employed as a biological sample in large-scale epidemiological studies in place of blood, and could facilitate the development of comparative One Health research projects.
We have in our pilot study shown that the levels to an emerging group of chemicals of concern, i.e., the synthetic phenolic antioxidants (SPAs) in dogs’ blood and saliva are at alarming levels. Establishing the exposure is urging, as more and more reports are coming in about their widespread use, abundance and little is known about their accumulated health effects.
Welcome!
