Ecological profiling

Considering evidence from both field and mesocosm studies, it may be concluded that certain groups of aquatic macroinvertebrates are sensitive to pyrethroids and that there can be changes, in the short term, at the population level and above with exposure to environmentally realistic concentrations of them. It should be possible to pick up effects of this kind in natural waters using ecological profiling, for example, the River Invertebrate Prediction and Classification System (RIVPACS). There is... 

LCI, where the system is quantified in a strict format of linked processes. Each process is described in terms of the physical inputs and outputs, both economic (raw materials, materials, products) and environmental (extractions from and emissions to the environment). Out of the total, an ecological profile is compiled listing and adding up all extractions and emissions of the system. An important methodological issue is allocation how to deal with multi-output processes This issue is especially important when dealing with waste management processes and will be dealt with below.

C.I. Reactive B lack 5, an important type of reactive dye, was comprehensively studied for its toxicological and ecological profile. It proved to be of low acute toxicity and is nonirritant, a weak sensitizer, and has no genotoxic potential. Even in its hydrolyzed form it is not hazardous to the effluent water [4],... 

The inventory data and the classified and characterized results are the ecological profile of the product or product system under study. These profiles may be used as modules for the life cycle assessment of subsequent products, for which these products are input of goods (e.g. LCl data of a steel production analysis are the basis for an LCA of a car made of tailored blanks such as building material profiles, for example, may be used to analyze buildings). A prerequisite for this is however that the methods and background data used for the modeling of the systems are identical. 

Alternatively, NPE can be substituted by surfactants like fatty alcohol ethoxylates (FAEO), or specially designed trademark products like Dispoiul A and Disponil AFX which have a more favourable ecological profile. 

Ecotoxicology (Table 29.2.3.10) Thiamethoxam (13) has a favorable ecological profile. It is practically non-toxic or only shghtly harmful to water vertebrates... 

Subsequently, an efficient method of ecological risk assessment was developed. It is based on a comparison of the predicted environmental concentration (PEC) and the predicted no-effect concentration (PNEC). If PEC < PNEC, the substance under consideration is expected to pose no ecological risk in the environment. A comprehensive review about the ecological profile was provided by J. Steber. ... 

Sulfosuccinates have a rather good ecological profile, with acute toxicities of about 33-39 mg/l.
