Module 6, Basic Ecotoxicology (6.027)
The importance in understanding the fate and effects of chemicals in environment

Popular science is full of phrases such as ‘biodegradable’ and ‘environmentally friendly’, but is there really anything that is friendly to the environment? And are biodegradable materials safe? And why should we be bothered if a Daphnia dies?

To enable the chemical industry to take a responsible position in the care of the environment, it is important for those involved to have at least a basic understanding of the terms used in describing the fate and effects of chemicals in the environment and to understand how to test for environmental impact.

This training module is intended for those working within the chemical industry who need to understand the relationship between potential hazards of materials to the environment and the SDS and also considered CLP classification with respect to the environment with definitions such as P, B, T and M.

Whether receiving or writing an SDS, it is necessary to understand Section 12 of the SDS and the corresponding classification in Section 2. There is a lot of jargon used and this Module is intended to demonstrate the basics of ecotoxicity and remove some of the mystery of this topic.

Topics Covered Include:

  • The importance of knowing potential environmental effects
  • Background to regulatory requirements for testing
  • Test method references
  • Basic types of ecotoxicity studies
  • Descriptions of terms and jargon
  • Importance of physico chemical properties
  • Supporting chemical analysis
  • Biodegradation and persistence
  • Introduction to endocrine disruption
  • Application of CLP with basic classification
  • Understanding of Section 12 of the SDS

Numbers on the course are restricted to enable an informal atmosphere of discussion and time is being made available for group work examining some of the practical issues of study design and data interpretation.

Advanced Ecotoxicity – Module 12

Module 6 covers the basics for SDS writing, but Module 12 that follows Module 6 takes it to the next level and covers difficult substances, sources of data, assessing environmental impact of mixtures, self-classification of mixtures etc and also introduces longer term studies. This in turn leads on to Modules 53 and 20 that cover the Chemical Safety Report and Extended-SDS. Please see for details of all courses and dates.

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.
