We investigate basic properties of context-free cycle and elementary cycle grammars with emphasis on the complexity of the recognition problem. In particular, it is shown that the description complexity is polynomial

This is achieved by the restriction to polynomial graph grammars and layout specifications, which can be computed efficiently by an attr

However, we must take care that simplicity in risk assessment process does not lead to oversimplification:

Their adsorption to soil increases with the aromaticity and electronegativity of functional groups attached to the sulfonyl phenyl amine core. Preferential flow in clay soils has been identified as a mechanism responsible for surface water contamination by SAs.

Second, ERA should include as much effort on collating and integrating ecological knowledge into the assessment in Tier 1 as is currently expended on gathering chemical and toxicological information on exposure a
