1. Emissions
The equipment was capable of measuring the concentration of each pollutant in parts per million (ppm) with accuracies of ± 4 ppm for CO, ± 500 ppm for C02 and ± 1 ppm for NOx.

2. Clogged Drains
Because of differences in concentration and secondary ingredients, the performance of caustic cleaners is more variable than that of acid cleaners.

3. Safety And Special Interest
Health and Welfare Canada's publication, Guidelines for Canadian Drinking Water Quality, states that the maximum acceptable concentration for sodium in drinking water has not been established, but it recommends you notify the appropriate health authorities if the sodium concentration exceeds 20 milligrams per litre.

4. Feeding Your Plants
Today, it is generally accepted that the actual choice of mineral salts for fertiliser mixtures is of little significance, provided a balanced concentration of the necessary elements is assured.

5. What Fertilizer To Use
Higher concentrations of standard balanced mixes are available such as 13-16-10 which has twice the strength of ordinary 6-8-6, and 15-30-15 which has three times the chemical concentration of 5-10-5, and some home gardeners have had difficulties with their plants due to using such mixes without realizing their power.

6. Lime
Whether a soil contains a lot of calcium or very little, is shown by the pH reading, which gives the concentration of hydrogen ions in the soil.

7. Aphids
Some of these additives can be harmful to plants and to soil bacteria if a concentration builds up. Detergents, in liquid or powder form, are not soap in the true sense of the word, nor are they suitable for control of aphids.

8. "Safe" Levels
It's a pollutant's concentration — its level in the air — which makes it dangerous. Unfortunately, not only is it difficult to measure the levels of pollutants in the home, but the very notion of "safe" levels is misleading.
