PERK-Walkthrough

Introduction

The aim of PERK is to predict and visualize concentrations of pharmaceuticals in the aqueous environment.

PERK acronym for Predicting Environmental concentration and RisK, is an R/Shiny application tool, aims to facilitate automated modelling and reporting of predicted environmental concentrations of a comprehensive set of pharmaceuticals derived from a wide range of therapeutic classes with different mode of action.

The tool helps users,
