Environmental risk assessment is required for substances which are classified as dangerous for the environment , or if there are the following other reasonable grounds for concern ... 

The 12th Adaptation to Technical Progress [7] of the Dangerous Substances Directive contained, for the first time, the requirements and criteria for classification and labelling of chemical substances dangerous for the environment and the 7th Amendment [8] to the Dangerous Substances Directive gave the symbol N for this which depicts a dead fish and a dead tree. 

CESIO Recommendation for the Classification and Labelling of Surfactants as Dangerous for the Environment , April 2003. 

However the EU classification of lead stabilisers as reprotoxic, harmful, dangerous for the environment and danger of cumulative effects and their presence (heavy metal) causing issues in waste management strategies, resulted in their agreed phase-out in Europe (see Section 7). 

In consequence zinc oxide is classified as dangerous for the environment (EU Classification 67/548/EEC, 29ATP 2004) with the Risk Phrases R50/53 (Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. 

The European Community classifies lead-containing anticorrosive pigments like Red Lead as well as zinc chromate, zinc potassium chromate, zinc tetraoxichromate, strontium chromate and, since 2000, also zinc phosphate as N, Dangerous for the environment (dead fish / tree) with the risk (R) and safety phrases (S) [5.112] ...

Flavouring ingredients may be flammable, toxic, corrosive, irritant, harmful, and/or dangerous for the environment.

Solubility is also a function of the pK. The pX a values are phenol 9.98, 2,4,6-trichlorophenol 6.15, tetrachlorophenol 5.16 and pentachlorophenol 4.75 As a rule, the solubility of the anionic form is much higher than that of the molecular form. For example, the solubility of the herbicide loxynil (pX a = 3.96) in water is 50 mgp and that of its potassium salt solubility in water is 107 gl . The pX a value of pentachlorophenol is 4.75, and its solubility in water is 14 mg 1 whereas the solubility of the commercially produced sodium pentachlorophenoxide is 330 gl . This shows that pentachlorophenol is very soluble in nonacidic wastewater, and its leakage from factories can be very dangerous for the environment. 

Nevertheless, as already mentioned, esterquats replaced DHTDMAC in the early 1990s. This move, a voluntary initiative from the industry, allowed the use of materials not classified as dangerous for the environment instead of materials classified as very toxic to aquatic organisms and potentially having long-term effects on the environment.

Classification and labelling as dangerous for the environment does not yet apply to chemical preparations, although criteria are being devel( )ed. 

There are currently no official Swiss criteria fcv classification of substances as dangerous for the environment , although in due course the EC scheme is likely to be adc ted. Hence the EC classification and labelling can be used for Switzerland, except for the EC hazard symbol. There arc also no criteria fw classification and labelling of chemical products containing substances which are dangerous for the environment , although their evaluation will take account of the content of such environmentally hazardous substances. 

Classification, packaging and labelling of preparations in Austria corresponds with the EC requirements of Council Directive 88/379/EEC [19]. The criteria for classification of iMeparations as dangerous for the environment have not been developed, but the proposed EC scheme can be followed based on taking account of the concentration and aquatic toxicity of substances in the preparation. 

Road and rail transport of chemicals in Australia is covered by the Australian Dangerous Goods Code (ADG Code) which corresponds with the UN transportation recommendations. The criteria used for the Australian user classification and labelling scheme closely parallel those of the EC, except for corrosives and physico-chemical hazards which are in accordance with the AE)G Code. However, there is as yet no classification of dangerous for the environment .
