# Acute Aquatic Toxicity Classification eBook

## START PROTECTING AQUATIC ECOSYSTEMS AGAINST ACUTE TOXIC EFFECTS 

FOR ERA'S CHRONIC AQUATIC TOXICITY GUIDE, [CLICK HERE](https://lando.era-environmental.com/ghs-chronic-aquatic-toxicity-guide)

While the GHS and CLP group all types of toxic effects on aquatic ecosystems under a single Aquatic Toxicity hazard class, ERA has decided to separate them into two individual eBooks for ease of classification. As the first of the two, this guide covers the three classification criteria for substances and mixtures that produce toxic effects in aquatic organism in the short-term after exposure.

Read it in place of the GHS Purple Book or the Guidance on the Application of the CLP Criteria for a comprehensive breakdown of everything there is to know about short-term, acute aquatic toxicity classification.

**This free guide will teach you:**

- A definition of acute aquatic toxicity on the basis of EC50 or LC50 values
- The three classification categories for substances and mixtures
- How to classify mixtures when there is data on the mixture as a whole, on substantially similar mixtures, on some or all components, and on mixtures containing ingredients without adequate aquatic toxicity data 
- The symbols, signal words, and hazard and precautionary statements that you should include on a label when classifying a substance as an acute aquatic toxicant
