The toxEval
R-package includes a set of functions to analyze,
visualize, and organize measured concentration data as it relates to
https://www.epa.gov/chemical-research/toxicity-forecasting or other
user-selected chemical-biological interaction benchmark data such as
water quality criteria. The intent of these analyses is to develop a
better understanding of the potential biological relevance of
environmental chemistry data. Results can be used to prioritize which
chemicals at which sites may be of greatest concern. These methods are
meant to be used as a screening technique to predict potential for
biological influence from chemicals that ultimately need to be validated
with direct biological assays.
The functions within this package allow great flexibly for exploring the
potential biological affects of measured chemicals. Also included in the
package is a browser-based application made from the Shiny
R-package
(the app). The app is based on functions within the R-package and
includes many convenient analyses and visualization options for users to
choose. Use of the functions within the R-package allows for additional
flexibility within the functions beyond what the app offers and provides
options for the user to interact more directly with the data. The
overview in this document focuses on the R-package.
