S-Risk updated to 1.2.6

Earlier today, version 1.2.6 of S-Risk was made available online. 

This is a minor bugfix release including a fix for some mercury compounds in outdoor air and for a problem in the extended report - see the Release Notes for full details.

S-Risk 1.2.6

S-Risk 1.2.6 is a minor bugfix release

  • Fix for an issue where evaporation to outdoor air was not consistently calculated for elemental mercury and methyl mercury. 

  • Fix for an issue where the calculated concentration in eggs was not shown in the "detail results" section of the PDF report.

S-Risk offline for 1.2.6 update

On Wednesday, September 26, the 1.2.6 update of S-Risk will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 10 am.
 
Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.

Helpdesk availability over the holidays

The S-Risk helpdesk will not be available from July 23, 2018 until August 3, 2018 (inclusive). Please keep sending your questions over, they will be answered as soon as possible from August 6, 2018 onwards.

S-Risk updated to 1.2.5

Today, a new release of S-Risk (version 1.2.5) was made available online. More information about the modifications done can be found in our Release note.
We advise you to carefully read this note as some adjustments made to S-Risk, might affect your simulations!
When having questions, do not hesitate to contact us!
 

S-Risk offline for 1.2.5 update

Update on 29/03/2018 11.20 am: The 1.2.5 update will take longer than expected. We do our best to make S-Risk available to you again as soon as possible. We would like to apologize for this inconvenience and thank you for your understanding!

Next week, on Thursday, March 29, the 1.2.5 update of S-Risk will be released. For this reason, the S-Risk web application will be temporarily unavailable between 8 am and 11 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.
 

S-Risk 1.2.5

This release includes a number of fixes and some maintenance and parameter adjustments.

General fixes & changes

  • Fix for incorrect water-filled porosity in the capillary zone (θwcz):

    By default, θwcz amounts to 0.34 (FL/BRX) or 0.391 (WAL) for the "generic" soil layer type. However, for a newly created simulation – which has one “generic” standard soil layer by default – this parameter was systematically set to 0 instead of the correct default value. For all other simulations, i.e., simulations where the default “generic” soil layer has been replaced by (an)other soil layer(s), the correct (default) value for θwcz is set. Also, in simulations where a second/third/… generic soil layer has been added, the correct (default) value for θwcz will be taken.

    We have discussed this issue with the FL, BRX and WAL government. In case the involved simulation(s) is (are) resulting from a closed file, you don't have to do anything. In other cases, i.e., when you want to make re-use of an involved simulation (created before release 1.2.5), either for creating a new simulation (by using the copy function) or for doing new calculations with the respective simulation, you manually have to adjust this parameter value. How can you do this?

  • Switch to Tier 2 mode and go to the “Soil” tab;
  • Select the generic soil layer, click on the “Customize” button and modify the soil layer name;
  • Behind "θwcz (m³/m³)", enter 0.34 (FL/BRX) or 0.391 (WAL) instead of 0.

    Contact us via info@s-risk.be if you have further questions!

  • Changed thousands separator for numbers to space, to avoid confusion with decimal numbers. 
  • Adjustments to summary report, so it will be saved correctly to PDF in Chrome.

Parameter adjustments

The Walloon government decided to change the toxicological threshold values of some default WAL chlorinated substances:

  • for hexachlorobenzene, the values for systemic threshold effects have been changed:
    • oral TDI and dermal TDU: 5.0E-5 mg/kg bw/d;
    • TCA: 2.45E-4 mg/m³;
  • for pentachlorobenzene, the TCA value for systemic threshold effects has been changed: 2.8E-3 mg/m³;
  • for 2,3,4,6 tetrachlorophenol, the TCA value for systemic threshold effects has been changed: 0.35 mg/m³.

Please, be careful when making re-use of simulations (created before release 1.2.5) containing these substances, either for creating a new simulation (by using the copy function) or for doing new calculations with the respective simulation! In both cases, you manually have to adjust this parameter value. How can you do this?

  • Switch to Tier 2 mode and go to the “Chemical” tab;
  • Select the appropriate chemical, click on the “Customize” button and modify the chemical name;
  • Go to the “Risk” tab and select the respective chemical;
  • Within the “Threshold effects – Systemic effects” panel, enter three times the appropriate value for TDI, TDU and/or TCA.

S-Risk offline for update

We will maintain our operating system. Therefore, the S-Risk web application will be temporarily unavailable between coming Monday (January 29) 4 pm and Tuesday (January 30) 12 am. Please communicate this further to all S-Risk users in your company, so this can be taken into account when planning S-Risk simulation work.
