68. Through the Joint FAO WHO Codex Alimentarius Commission, work has been proceeding on developing internationally agreed food standards and maximum residue levels for pesticides and other agro chemicals, and on establishing maximum levels for environmental contaminants.

Iran submitted the results of an atmospheric and air quality model that it used to calculate the transport of contaminants from the oil well fires to demonstrate that some of the contaminants reached the territory of Iran.

This allows the room to exhaust air that contains infinitesimal quantities of radioactivity and contaminants.

The effective disposal of those contaminants will require their permanent isolation from the human biosphere.

An air purifier is a device which removes contaminants from the air.

The U.S. and EU are two of the largest global import markets for tuna. Because new EU rules allow testing imported fish for mercury levels and other contaminants, import restrictions and declining demands may soon result.

Many of these contaminants can be hard to remove from drinking water using standard purification techniques.

The alpha and beta isomers are contaminants of lindane and have similar properties to the gamma isomer.

Closely associated with the challenge of optimizing remediation is that of understanding how contaminants will behave as a result of natural processes.

In general, carbon block filters are more effective at removing a larger number of contaminants, based upon the increased surface area of carbon.

Syria states that, as a result of exposure to the aforementioned airborne contaminants, sites of cultural and archaeological significance were damaged across the country.

(ii) Developing capacities in the area of water desalination, treatment of contaminants, rainwater harvesting and water efficiency through technology transfer and sharing of best practices

The capacity for nanoparticles to function as a transport mechanism also raises concern about the transport of heavy metals and other environmental contaminants.

Taking note of the special circumstances pertaining to the continued presence of radioactive contaminants in certain Pacific Islands Forum nations,See A 61 558, annex.

It begins to melt below the boiling point of water and does not drive off the oily contaminants for which it is a sponge.

And here's a map of that condition, showing the contaminants in yellow and green, exacerbated by this new flow of storm surge and sea level rise.

It's a river that carries with it all the things that rivers tend to carry these days chemical contaminants, pesticide runoff.

OSCAR includes an oil spill physical fates sub model that estimates the distribution of contaminants on the water surface, on shorelines, in the water column and in sediments as well as exposure and population sub models which together estimate the effects of contaminants on eggs, larvae, juvenile and adult fish, wildlife and lower trophic level biota.

Iran submitted an analysis of satellite images used to track the movements of the oil spills and contaminants from the oil well fires from Kuwait to Iran.

We see in our material flows that car steels don't become car steel again because of the contaminants of the coatings bismuth, antimony, copper and so on.

In 2010 it obtained ISO 13485 accreditation in the connection with the production of starting materials for experimental drug production, and with manucacturing of reference standards of food contaminants.

So a couple of years ago, we had a scandal which killed about 80 people around the world, because of contaminants that crept into the heparin supply chain.

In determining incompatibility, consider the substances, containers, and contaminants that the substance or mixture might be exposed to during transportation, storage and use.

These levels are overlooked often because of the nature of the construction of these levels.

Syria alleges that its environment was damaged by airborne contaminants from the oil well fires in Kuwait and that this resulted in the death of 624,061 sheep.

Innovations can occur at all levels of government, i.e., central and local levels.

I should like to remind the members of the General Assembly of the continued presence in the Marshall Islands of dangerous residual radioactive contaminants from United States nuclear weapons testing programmes.

So higher levels of fecal coliform require higher levels of chlorine, threatening those aquatic organisms.

What are the environments that lead to unusual levels of innovation, unusual levels of creativity?

When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.

We hope that in the near future, we'll be able to create model organisms that can break down not only phthalates but a wide variety of different contaminants.

Most contaminants are coliform bacteria and faecal streptococcus, and among chemical ones, there are ammonia, nitrates, nitrites, rare heavy metals and other toxic agents.
