1 The World Health Organization recognizes six main types of air pollutants carbon monoxide, nitrogen dioxide, particulate matter, sulphur dioxide, tropospheric ozone and suspended particulate matter.

(iii) To undertake regular monitoring of air quality, including harmful pollutants such as small particulates which are not measured on a regular basis in some parts of the world

For instance, tropospheric ozone is a powerful greenhouse gas and particulate pollutants can have strong effects on local and regional climate.

B. Pollution modelling and cataloguing of objects and particles

More recently the scientific community has been striving to develop robust techniques for documenting long distance transport of ozone, particulates and persistent organic pollutants.

Measures should be undertaken only if they are likely to result in more positive than negative effects.

Nor are we choking on pollution. Whereas the Club of Rome imagined an idyllic past with no particulate air pollution and happy farmers, and a future strangled by belching smokestacks, reality is entirely the reverse.

Iran estimates that up to 37 per cent of the polluting substances, including saline compounds, from the oil well fires in Kuwait were deposited on its territory.

The cooperative programme should also incorporate an extensive monitoring and assessment component to operate throughout its entire duration. Monitoring should relate to both ecological and economic parameters.

(a) The probability of space debris impacts for a particle of a given size

The dilemma is that all particles, whether white or black, constitute a serious problem for human health. Every year, an estimated two million people worldwide die prematurely, owing to the effects of breathing polluted air.

In order to prevent space pollution by fine particulate debris, it is proposed to take the following measures

If you put particles in them, and they go shooting out the tip they're like miniature linear accelerators or electron guns.

And not just iridium it's filled with glassy spherules, and it's filled with quartz grains that have been subjected to enormous pressure shock quartz.

The Particle Emissions Dilemma

261. The price reform (freeing electricity consumption prices and solid and liquid fuel prices) resulted in a drop in electric power consumption, as well as in emissions of sulphuric acid, solid particles and other pollutants of power generation.

The 60 kg microsatellite would be able to provide images of cultivated fields, natural vegetation and pollution around the globe.

That's a ball of water, and those are dirt particles.

Iran provides chemical analyses of samples taken from cultural heritage artefacts and sites which suggest contact with particulate matter and hydrocarbons, but they are not sufficient to enable the Panel to determine the time of contact or the origin of the particulate matter.

Effluents and emissions are generated to some extent by production processes in a weapons complex and can be solid, liquid, gaseous and particulate in form.

Some of them are agglomerating together to form larger particles.

GDP counts everything from air pollution to the destruction of our redwoods.

pollution.

And we chop those strands into what are called pellets.

So, solving the problem of pollution with more pollution.

Orbital debris shields for both manned and unmanned spacecraft can be quite effective against small particles.

In order to relate the size of the impact feature with the size of the particle, ground calibration tests (hypervelocity impact tests) have been performed for different materials.

We heard about polluted air, polluted water, poisoned food.

In the Federation there is no single detection system for basic indicators of air pollution, either sulphur dioxide or floating particles.

It's plastic pollution.

The particle vaporizes and then recondenses on the surrounding surfaces.

Second, we are both responsible for and the victims of our own pollution.

We heard about polluted air, polluted water, poisoned food.

To reduce mercury pollution of international waters by emissions emanating from small scale gold mining

However, Kuwait provided only a brief description of the study and medical screening programme.
