- [ARTF | Objectives](https://exposuretf.com/artf-objectives/) - ARTF Objectives Objectives The goal of ARTF was to generate a database of generic agricultural reentry transfer coefficients (TCs) applicable to all crop/activity scenarios. ARTF was made possible by a growing recognition that TCs can be generically applied to any pesticide product, regardless of the test substance used to generate the TC. This approach is
