Depositions of acidifying substances have decreased since about 1985.

Will I ever leave this place with its cinder and soot

The pollutant parameters pH, SO2, O3, HNO3 and PM deposition were included.

The modelling was done as a sensitivity analysis, where key model parameters were changed using large but still feasible ranges.

All these items ended up in Gregor's room, even the box of ashes and the garbage pail from the kitchen.

Now, you can reduce the embodied energy by about 25 percent by using high fly ash concrete.

Chemical vapor deposition (CVD) is a chemical process used to produce high quality, high performance, solid materials.

Particulate matter deposition to the surrogate surface (PMdep) in wind exposed positions as a function of particle air concentration (PM10)

Accumulated total nitrogen deposition at the integrated monitoring sites ranged from 400 to 2000 kg nitrogen ha 1.

The largest of all the Galapagos volcanos Sierra Negra recently blew smoke and ash 7 miles into the sky

Incinerators are expensive to operate and release the pollution from the waste either as chimney emissions or with in the ash which requires burial.

As indicated at paragraph 79 of the second F4 report, the Panel transferred a part of Iran's claim No. 5000379 relating to its inability to realize fishing production increases from a proposed fisheries development project to a future instalment.

Nitrogen deposition was shown to be positively correlated with nitrogen leaching, especially in nitrogen enriched soils.

Where more than one approach or technique is appropriate to achieve the desired goal, the most cost effective option should be selected.

Pollution from land based activities includes municipal, industrial and agricultural wastes and run off, as well as atmospheric deposition.

Direct filtration, which is typically used to treat water with low particulate levels, includes coagulation and filtration, but not sedimentation.

Solid fossil fuels are most frequently used for heating, which contain 2.5 4 per cent sulphur and which produce large quantities of sulphur dioxide and ash (20 30 per cent).

The effectiveness of measures should be monitored to ensure that targets are met and measures should be designed to be sufficiently flexible and responsive to new information obtained from such monitoring.

Incineration, while reducing the volume of wastes, is prohibitive in terms of cost and still requires disposal of ash containing potentially hazardous substances in high concentrations.

When she opened her eyes in the morning it was because a young housemaid had come into her room to light the fire and was kneeling on the hearth rug raking out the cinders noisily.

Iraq contends that Saudi Arabia's claim for damage to fisheries resources is a commercial claim rather than a claim for environmental damage, and consequently, there is no need for high risk, long term compensatory projects such as the proposed shrimp and grouper programmes.

Accumulated total nitrogen deposition for the years 1880 2000 was calculated at ICP Integrated Monitoring sites and other sites in the CNTER project database in cooperation with CCE.

Iran also relies on the results of a study on the transport of pollutants from the oil well fires, using satellite imagery and black rain measurements.

Iraq states that Iran has not provided sufficient evidence to demonstrate that oil pollution in Iranian waters as a consequence of the conflict affected Iranian fisheries resources.

He gazed into the cellar from all sides and points of view by turns, always lying down to it, as if there was some treasure, which he remembered, concealed between the stones, where there was absolutely nothing but a heap of bricks and ashes.

The Panel considered that this part of the claim was for depletion of or damage to natural resources. The deferred part of claim No. 5000379 has been included in claim No. 5000301.
