Such reviews will take into account the best available scientific information on the effects of the deposition of persistent organic pollutants, assessments of technological developments, changing economic conditions and the fulfilment of the obligations on emission levels.

Each Party that has one or more regulatory and assessment schemes for new pesticides or new industrial chemicals shall take measures to regulate with the aim of preventing the production and use of new pesticides or new industrial chemicals which, taking into consideration the criteria in paragraph 1 of Annex D, exhibit the characteristics of persistent organic pollutants.

methods for the assessment of the toxicity of hazardous substances and the noxiousness of pollutants;

The method of determining the upper and lower assessment thresholds of those pollutants laid down in that Directive should be amended in order to clarify the calculation procedure.

improving the monitoring and assessment of air quality, including the deposition of pollutants, and the provision of information to the public, including the development and use of indicators;

LIST OF ATMOSPHERIC POLLUTANTS TO BE TAKEN INTO CONSIDERATION IN THE ASSESSMENT AND MANAGEMENT OF AMBIENT AIR QUALITY

"assessment" means any method used to measure, calculate, predict or estimate the level of a pollutant in the ambient air;

'assessment` shall mean any method used to measure, calculate, predict or estimate the level of a pollutant in the ambient air;

"assessment" shall mean any method used to measure, calculate, predict or estimate the level of a pollutant in the ambient air;

this assessment shall be based on information on the quality of the waste concerned and measurements of the emissions of the said pollutants;

The trigger value of 0.1 µg/ l that is used in some assessment frameworks as a surrogate zero for pollutants in groundwater is not mentioned in the Groundwater Directive (80/ 68/ EEC) and is specific for pesticides and biocides in the replacement Groundwater Directive.

Member States which do not have representative measurements of the levels of pollutants for all zones and agglomerations shall undertake series of representative measurements, surveys or assessments in order to have the data available in time for implementation of the legislation referred to in Article 4 (1).

The objective is to detect and describe global change processes, associated with greenhouse gas emissions and atmospheric pollutants from all sources, including those resulting from energy supplies, transport and agriculture, to improve prediction and assessment of their global and regional impacts, evaluate mitigation options and improve the access of European researchers to facilities and platforms for global change research.

Under Article 5 of Directive 97/24/EC, the Commission is required to submit, to the European Parliament and the Council, within 24 months from the date of adoption of the Directive, a proposal prepared on the basis of research and an assessment of the costs and benefits deriving from the application of tightened-up limit values and laying down a subsequent stage during which measures will be adopted aimed at further tightening of the limit values for pollutants of the vehicles concerned.

Within 24 months from the date of adoption of this Directive, the Commission shall submit to the European Parliament and to the Council a proposal prepared on the basis of research and an assessment of the costs and benefits deriving from the application of tightened-up limit values and laying down a subsequent stage during which measures will be adopted aimed at further tightening of the limit values for pollutants and the sound level of the vehicles concerned, as laid down respectively in Chapter 5, Annex II, Tables I and II and Chapter 9, Annex I.

Air pollution monitoring and modelling using acceptable common emission factors and methodologies shall be carried out in the assessment of atmospheric deposition of substances, as well as in the compilation of inventories of quantities and rates of pollutant emissions into the atmosphere from land-based sources."
