proteomics is the study of protein molecules in the cell to find association with the composition and cellular response to toxic chemical substances. It is an innovative tool in pharmacology, toxicology and environmental toxicology.

Proteins are the primary structural and functional molecules in the cell, and are made up of a linear arrangement of amino acids. The linear polypeptide chains are folded into secondary and tertiary structures to form the functional protein. Unlike the static nature of the cell's genes, proteins are constantly changing to meet the needs of the cell.

Characterizing the identity, function, regulation, and interaction of all of the cellular proteins of an organism, the proteome, will be a major achievement. Studies of changes in the proteome of cells and tissues exposed to toxic materials, compared to normal cells, is being used to develop an understanding of the mechanisms of toxicity. As proteomics tools become more powerful and widely used, protein and proteome changes in response to exposures to toxic substances (fingerprints or response profiles) will be developed into databases that can be used to classify exposure responses at various levels of organization of the organism, thus providing a predictive in silico toxicology tool.

pump and treat is the technology which involves the xtraction of groundwater from an aquifer and subsequent treatment above ground. Extraction is usually conducted by pumping groundwater from a well or trench. Treatment can include a variety of technologies that reduce contaminant toxicity or mobility. Some of the commonly used above-ground treatment technologies are air stripping, activated carbon adsorption, filtration, and metals precipitation.

pyrolysis is the chemical decomposition of organic substances by heating. pyrolysis is a special case of thermolysis. During pyrolysis no oxigen is present, so that it is diffent of combustion. It may proceed in isolated space or under water. It occurs spontaneously at high temperatures and in general, it produces gas and liquid form products and leaves a solid residue rich in carbon. pyrolysis on extreme temperature leaves elementary carbon as residue, it is called carbonization. The pyrolísis in water is also called hydrous pyrolysis. The efficiency of pyrolysis can extremely be increased by using special catalists.

Under Directive 67/548/EEC these are standard phrases indicating the special risks arising from the dangers involved in using the substance or preparation. For example "Danger of very serious irreversible effects", "Limited evidence of a carcinogenic effect". When the current provisions are repealed and GHS enters into force, the R-phrases will be replaced by "hazard statements". (Source: REACH Glossary)

The concrete risk-phrases are enlisted in the entry of verbal characterisation of risk of chemicals

the Committee for risk Assessment (RAC) is an Agency committee that is responsible for preparing the opinion of the Agency on evaluations, applications for authorisation, proposals for restrictions and proposals for classification and labelling under the classification and labelling inventory task and any other questions that arise from the operation of this Regulation relating to risks to human health or the environment. The RAC consists of at least one but no more than two members from the nominees of each Member State appointed by the Management Board for a renewable term of three years. The Committee members may be accompanied by advisers on scientific, technical or regulatory matters. (Source: REACH Glossary)

RCR = Risk Characterisation Ratio, the ratio of Predicted Environmental Concentration (PEC) and Predicted No Effects Concentration (PNEC) (PEC/PNEC). See also Risk Quotient (RQ).

REACH is the Regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force on 1^st June 2007 to streamline and improve the former legislative framework on chemicals of the European Union (EU). REACH places greater responsibility on industry to manage the risks that chemicals may pose to the health and the environment.
In principle REACH applies to all chemicals: not only chemicals used in industrial processes but also in our day-to-day life, for example in cleaning products, paints as well as in articles such as clothes, furniture and electrical appliances.
The aims of REACH are to:

• Improve the protection of human health and the environment from the risks that can be posed by chemicals

• Enhance the competitiveness of the EU chemicals industry, a key sector for the economy of the EU
• Promote alternative methods for the assessment of hazards of substances
• Ensure the free circulation of substances on the internal market of the European Union.

Annex XVII of REACH lists all restricted substances and the conditions of their restrictions under REACH.

in connection with REACH you can find user-friendly information on the website http://reach-support.com/

The information required in technical dossiers is dependant on the annual tonnage of the substance, and is specified in Annexes VI-X of REACH. It includes:

• Registrant details;
• Joint submission details;
• Third party representatives;
• Substance identity;
• Manufacture and use;
• Classification and labelling;
• Guidance on safe use;
• Exposure information (1 to 10 tonne band only);
• (Robust) study summaries reporting on the physiochemical, toxicological, and ecotoxicological properties of the substance;
• Proposals for additional testing;
• Justification to keep commercially sensitive information out of the public domain.

Annex VI specifies the general information which must be provided for all substances regardless of tonnage.

Annexes VII to X give details of the physicochemical, toxicological and ecotoxicological properties that must be provided for each tonnage band.

Annex XV of the REACH regulation lays down general principles for preparing Annex XV dossiers to propose and justify
(a) harmonised classification and labelling of CMRs, respiratory sensitisers and other effects
(b) the identification of a substance as a CMR, PBT, vPvB or a substance of equivalent concern
(c) restrictions of the manufacture, placing on the market or use of a substance within the community.
Proposals for restrictions and identification of substances of very high concern can be prepared by a Member State Competent Authority or by the Agency on a request from the Commission. Proposals for harmonised classification and labelling can be prepared by a Member State Competent Authority.
