black font. The first tab (starting from the left), named "Airborne PAH ratio & BLV", displays the estimated BGV based on the recommendation of ACGIH and a defined exposure scenario, the distribution of 1-OHP concentrations adjusted by the PyrT/BaP ratio, as well as the probability of exceeding the estimated BGV. The "Data source" tab provides the inventory of PyrT/BaP ratios from this work. The "Respiratory assigned protection factors" tab provides a table listing all of the respiratory assigned protection factors found in the literature. The "Exposure limits values" tab provides a table listing all of the airborne BaP and urinary 1-OHP limit values found in the literature. The "News & Articles" tab will report articles describing, using, or citing the PAH HBM tool. The "Help/Info" tab provides general information regarding the PAH HBM tool, such as the goal, strengths, and limitations of the tool, as well as information regarding table and figure interactivity, information pertaining to the condition of use, data privacy, data protection, and legal mentions, and how to report bugs or mistakes. The "Contact" tab provides contact information details, while the "Mentions légales" tab stipulates the legal mentions in French.

The blue box on the left of the tool allows the user to define an exposure scenario. The user can define an occupational context by choosing a country and specifying the SEG (sector, process/post, and activity). For the PyrT/BaP ratio, it is possible to use data from this literature review to make a simulation or to upload files that are not stored or kept to ensure the safety and anonymity of the data. It is possible to account for respiratory protection, such as in a recent study (Valière et al. 2022). If the user wants to estimate the probability of exceeding the estimated indicative BGV, it is possible to either make a simulation regarding 1-OHP concentrations or upload a file. The user can also set a BLV instead of using the one that was estimated. Once the exposure scenario has been defined, the user must click on the "run new analysis" button on top of the box to execute the calculations. It can take from a few seconds to a few minutes to generate all the graphs and tables, depending on the number of simulation runs chosen, the user internet connection, and the user computer power. Help buttons are available for every choice to make, with, for instance, instructions on how a file should be structured before being uploaded.

All of the tables and figures available on the PAH HBM tool are interactive. There is a help button below each table, named "How to interact with this table?" which explains how to interact with all the tables.

On top of each table (on the left), there are seven action buttons. The “Copy” button allows the user to copy the table to a clipboard. The “CSV”, “Excel” and “PDF” buttons enable the user to export the table to CSV, XLS, or PDF format, respectively. The “Print” button allows the user to print the table. The user can choose which columns to visualize using the “Column visibility” button. The last button, “Show 10 rows”, allows the user to choose the number of rows to display. When the former button is not set on the “Show all rows” option, the user will have to click on the buttons under the table (on the right) to navigate through the table. Beware, for exporting or printing the entire table, the user needs to first click on the number of rows to display button (named “Show 10 rows” by default), then choose the “Show all rows” option, and finally click on one of the three export/download buttons. The interactive tables allow the user to perform queries, either on a specific column or on the entire table. The global search is performed across all searchable columns and starts when typing text on the “Search” rectangle/bar located on top of the table (on the right). Searching on individual columns can be performed by typing text on the white rectangle/bar below each column header. Queries are not case-sensitive and provide on-the-fly filtering with immediate feedback to the user. For the global search, the order of the words in the query does not matter. Clicking on the cross symbol that appears on the right of the query will cancel the search. Clicking on the arrowhead facing the top of the web page will sort the chosen column either alphabetically or in ascending numerical order, depending on the type of data the column contains (numerical values or texts). It is also possible to change the order of the columns in a table by clicking and dragging the column header to the left or to the right. References and access links are underlined and written in blue font and can be clicked on to open the website where the paper/record can be viewed/obtained. Note that empty cells correspond to non-reported values.
