Please see below for a request for your input. _______________________________________________________________________________________________________ Dear Colleague, We would like to invite you to participate in an international survey that examines the use of alternative approaches for toxicity testing in various settings. In particular, we are interested in information regarding your views on alternative approaches and about the various factors that drive or inhibit their adoption. We are surveying members of various scientific societies and professional associations to gather information about these issues. The survey is being conducted by the UCLA Sustainable Technology and Policy Program, an interdisciplinary program of the UCLA Fielding School of Public Health and UCLA School of Law. The survey will take about 15-20 minutes. Your participation in this survey is fully voluntary and can be stopped at any point before, during or after the survey. We hope you will participate; your knowledge and experience will greatly enhance the usefulness and accuracy of the research. The survey is available through this link: https://acsurvey.qualtrics.com/SE/?SID=SV_e8MFLwqAuSuN60l Thank you for your consideration.
