Acidification, ground level ozone, eutrophication, nitrate particles secondary PM.
These pollutants are major contributors to acidification, eutrophication, ground level ozone as well as particulate matter.
Ground level ozone and particulate matter(“fine dust”) are the pollutants of most concern.
This amendment will contribute to achieving ambient air quality targets especially concerning ground level ozone.
Ground level ozone is a pollutant which crosses national borders and is also the third most important greenhouse gas.
The proposal for a directive on national emission ceilings aims to tackle acidification,eutrophication and ground level ozone simultaneously.
Ground level ozone is a serious air pollutant which creates considerable problems for public health and the environment.
EU action has focused on establishing minimum quality standards for ambient air andtackling the problems of acid rain and ground level ozone.
This implies that the concentration of PM2.5 would be reduced by 75% and ground level ozone by 60% from what is technically feasible by 2020.
One sets national emission ceilingsfor certain atmospheric pollutants, and the other is a proposal to combat ground level ozone.
Ground level ozone is a transboundary air pollutant formed in situ in the atmosphere from precursor emissions of volatile organic compounds(e.g. petrol vapour) and nitrogen oxides.
This amendment to Directive 97/68/EC will contribute to achieving existing ambient air quality targets, especially as ground level ozone is concerned.
Given the role of volatile organic compounds in the formation of ground level ozone, the Commission will examine the scope further to reduce VOC emissions at petrol filling stations.
For human health, the situation is more complex as there is no known safe level of exposure for some pollutants such as particulate matter and ground level ozone.
CO is a precursor of the greenhouse gas, carbon dioxide(CO2) and of ground level ozone, but its contribution to the problems of global warming and summer smog is relatively low.
The threat to farmland comes from change of use, industrial expansion, transport installations,atmospheric pollution, ground level ozone and other pollutants.
The first is to provide data to allow an assessment of the changes in the new car fleet which could impact on other Community environmental objectivessuch as air quality, acidification and ground level ozone.
In the Commission's view such a monitoring scheme would not only allow to assess the changes in the new car fleet(and their potential impact on other Community environmental objectives: air quality,acidification, ground level ozone) but also to verify whether every manufacturer is contributing to the success of the environmental agreement envisaged between the Commission and ACEA.
In addition, the proposed monitoring scheme will provide information on the changes in the passenger car fleet, resulting from the implementation of the strategy,which may affect other Community policy objectives such as air quality, ground level ozone, regional acidification and road safety.
The Commission agrees that emissions from shipping make a significant contribution to the problems of acidification,eutrophication and ground level ozone in the Community and that this should be tackled.
Ecosystems are also damaged by(1) the deposition of the acidifying substances- nitrogen oxides, sulphur dioxide and ammonia- which lead to loss of flora and fauna;(2) excess nutrient nitrogen in the form of ammonia and nitrogen oxides can disrupt plant communities, leach into freshwaters leading in each case to a loss of biodiversity(called“eutrophication”);and(3) ground level ozone that results in physical damage and reduced growth of agricultural crops, forests and plants.
Volatile organic compounds and other industrial solvents contribute to the formation of ozone at ground level.
