Module 12, Advanced Ecotoxicology (12.123)
There is more to ecotoxicity than you thought….

Following from Module 6 at the ‘basic’ level, we know that standard test data on the short-term effects to fish, Daphnia or algae can provide us with classification end points. We also know that some chemicals will biodegrade or hydrolyse in the environment and using these data, we can make basic assessments and complete (and understand) Section 12 of the SDS.

However, it is an unfortunate fact of life that many chemical products fail fit into the ideal of simple classification and risk assessment and in these cases, an advanced level of understanding in ecotoxicology is required.

This training course has been put together to follow-up from the Basic Ecotoxicology course (Module 6) and is intended to build on these basic principles by considering more than acute aquatic toxicity studies. A further aim of the module is to help those reading data take a more critical approach to look for anomalies and to be able to pick out environmental concerns from the minimal data that are usually available to SDS writers.

Time is also given to finding data and to assess the quality of data; the internet is a wonderful tool and with the disseminated REACH dossiers providing unprecedented quantities of data it is even more important to discern the quality of data. The next challenge is to use this for self-classification of mixture.

The course is aimed at those with a reasonable technical understanding of ecotoxicology, have ideally attended Module 6, and are ready to discuss chemistry, environmental fate and ecotoxicity.

Topics Covered Include:

  • Dealing with difficult substances and mixtures
  • An understanding of environmental risk
  • Consideration of atmospheric, aquatic and terrestrial compartments
  • Finding data and assessing quality
  • Interpretation of data and identification of concern from minimal data
  • Relevance of P, B, T and M (and vP, vB and vM)
  • The use of computer models, read across and educated guessing
  • Long-term effects of chemical, including the movement of pollutants, including endocrine disruptors
  • Deliberate and accidental release scenarios

Numbers on the course are restricted to a maximum of 16 in order to create an informal atmosphere for discussion. Time will be made available for group work to examine some of the practical issues of study design and data interpretation. Delegates will be provided with an advanced reading list, with recommendations for documents to bring to the training day.

Module Tutor

The training will be given by Mark Selby of Denehurst Chemical Safety Ltd. Mark had many years' experience in this sector, from manufacturing industry, to contract test laboratories and now consulting.

    Module Deputy

    Sue has many years’ experience in the pharmaceutical, aerospace, marine, energy and nuclear industries and now works as a consultant covering REACH compliance, classification & labelling, safety data sheets and transport.

    Module Presentation

    We will deliver this training using an online system, which we have used successfully for other CHCS events and training. There is no charge to delegates for using the software. The licence cost is borne by CHCS.

    The sessions will run live and delegates can interact with the tutor and other delegates using their device microphone. The tutor will use a PowerPoint presentation, just as they would in face-to-face training.

    We will provide you with copies of the presentation and all other supporting documentation in advance of the training, by email. We will provide you with a document giving more details about using the software plus some tips for getting the best out of the day.

    Delegate Feedback

    Comments from previous delegates on this training module:

    “Lots of examples; good presentation material; very engaging speaker”

    "Everything excellently explained – gave me a lot of insight on an area I had little knowledge of previously"

    “The practical examples and reference to the guidelines were particularly useful”

    “Overall, I truly enjoyed both sessions and will definitely go back to watch the recording to refresh my mind”


    CHCS Training Courses are only available to CHCS members and members of our partner organisations listed below.

    If you aren't a member of CHCS we'd be pleased to welcome you to the Society, and then you may register for training courses (and other CHCS member-only events). You can JOIN US by completing the form on this website.

    Our online courses are priced at £285.00 (+VAT). However, we also offer a discount price of £260.00 (+VAT) for bookings taken up to 6 weeks before the course date.

    If you are a CHCS member, use your CHCS login details, then click on the "REGISTER" button shown on the right-hand-side of the screen. You will then be able to access either the Discount or Full-Price rate depending on the date. 

    You can pay online using your credit card, or have an invoice sent to you for payment by credit card or bank transfer. However, we only accept Credit Card payments for any registrations made within 5 weeks of the date of the course.


    Members Of BADGP & SCHC

    CHCS is delighted to have arrangements with:

    Members of both organisations can attend CHCS events at CHCS member-only rates and vice versa. If you are a member of either organisation and wish to attend this course, please visit the Partners page of our website and follow the links to the web page of the organisation to see how to register. 

    Please note these Conditions

    Delegates can be substituted at any time, subject to payment of a membership fee if applicable. However, once booked, the full fee is payable. As this is a limited space training event, refunds can only be made if CHCS is notified in advance, and is able to successfully re-offer the place to another delegate.

    CHCS reserves the right to alter or cancel the programme due to circumstances beyond our control, including insufficient interest. If CHCS cancels, then refunds will be made.

    For registrations made within 5 weeks of the course date, we only accept payment by Card.
