The real problem we are having about our health is not that there are residues of pesticides in our food.
The real problem is that there are only residuesof nutrition left in our foods.
In fact some of these naturally occurring substances are far more dangerous than the toxic residues of pesticides in our foods.
The above examples of the method of Residues are all quantitative; but the method is often employed where exact estimates are unobtainable.
It is desirable to note the contents of the residues in the retort, for it is our belief that these are the materials to which the author refers as "lees of the water which separates gold from silver," in many places in Book VII.
There is no indication in any of Agricola's works as to whether this was some special wood-ash or whether it was the calcined residues from wool washing.
In either event, whether obtained from wool residues or from lixiviation of wood-ash, it would be an impure potash.
A third way of making it is from the residueswhich fall to the bottom in copper furnaces.
This may be residues from roasting and leaching pyrites for vitriol, etc.
Therefore one is driven to the conclusion that the feces must have been the residues left in the retorts when nitric acid was prepared.
The litharge does not cohere, but falls to pieces like the residuesfrom malt from which beer is made.
The lead cylinder is then inverted, and any residues removed with a brush.
Hence we see that the solid residues from petroleum are unstable compounds like the coals and lignites, and in virtue of their organic nature are constantly undergoing a series of changes of which the final term is combustion or oxidation.
Whatever the variety of petroleum may be, if exposed for a long time to the air it undergoes a spontaneous distillation, in which gases and vapors, existing or formed, escape, and solid residues are left.
It will be shown that the ester groups can be actually localised in various ways, as in the main entering the cellulose residues alpha and beta.
It would be of importance to be able to formulate the exact mode of union of the lignone with the cellulose residues to constitute the lignocellulose.
We must note, however, that the celluloses of the lignocelluloses are obtained as residues of various reactions, and are not homogeneous.
It is probable, therefore, that the water combining with the residues at the moment of their resolution is relatively small.
The tissue residues left after extracting the amyloid constituent, as above described, were subjected to acid hydrolysis.
The residues were found to yield considerable proportions of furfural.
The filtrate from these precipitates containing only fractional residuesof acetone still shows opalescence.
The residues of both operations are melted up with the pitch.
In Fremy's process for separating osmium from the residuesof platinum ore, ruthenium occurs in a dioxide.
The copper, which in some residues is met with to the amount of 4 per cent.
Recent investigations appear to indicate that organic products of decomposition of plant residues in the soil may exert powerfully toxic effects upon succeeding generations of the same, or of different, plants growing on the land.
There were fourteen million tons of these residues on the Broken Hills dumps and from them he derived large returns for the company that he had organized to purchase the property.
It cannot be deducted from either farmer or consumer, it does not affect the cost of living, it does not destroy initiative in the individual if it leaves large and proper residues for dependents.
On allowing these solvents to evaporate spontaneously, residues are obtained which will give the reactions already detailed.
It is therefore certain that large quantities of organic sulphur-compounds may be found in the human intestinal canal, for with individuals who suffer from constipation, the residues of the biliary secretion accumulate for many days.
Some knowledge of the effect of chemical residues in paper is important, not only in regard to the deterioration which takes place in the fibre itself, but also in relation to the fading of the ink which is used.
The residues of chlorine which may be left in pulp after bleaching are frequently neutralised by the use of substances termed antichlors, which react with the calcium hypochlorite, converting it into chlorides.
The questions relating to the chemical residues of paper can only be adequately dealt with by a discussion of actual cases which arise from time to time.
It was reported to me that crows caused damage to watermelons which are extensively grown in the sandhills region but no residues of this crop were found in any pellets collected.
These percentages were probably high, since there is a high proportion of indigestible residues in oats.
Nevertheless, grasshoppers and beetles remained the predominant animal-food residues into December and frequencies of occurrence remained relatively high.
Certain foods that lack hard parts may leave no recognizable residues in pellets.
Having a high content of indigestible residues they probably showed up in the pellets in percentages out of proportion to their importance in the diet.
Residues of cherry and wheat constituted the only plant foods found in the pellets.
Data From Analysis of Pellets Data obtained from the analysis of pellets were grouped in biweekly collections, and percentages of various food residues in the pellets collected within each biweekly period were averaged.
One limitation of data based on material from pellets is the impossibility of closely correlating the volume of indigestible residues with the proportion of food items actually eaten.
The percentages by bulk of different food residues (excluding sand and other extraneous material) were estimated in each pellet and recorded.
Wheat and sorghum constituted more than one-half of the foodresidues in this period.
Such correlation is prevented not only by the different percentages of indigestible residuesin different food items but also by irregularities in regurgitation and in the efficiency of the crow's digestive system.
It is almost impossible to prepare a pure hydrated manganese dioxide owing to the readiness with which it loses oxygen, leaving residues of the type xMnO.
Another theory puts it as the deposit from the saline residues of fresh-water streams.
The above figures have a purely empirical value, since they represent a complicated mixture of various residues derived from the celluloses and compound celluloses.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "residues" in a variety of sentences. We hope that you will now be able to make sentences using this word.
