Fate of thoroughgoing pollutant = its tape drive + its transformation

What does this sentence mean???

This means that the determination of fate of organic pollutants divides into two parts:

1- Determination of appliance of transport and/or how much involving in transport process.

2- Determination of mechanism of transformation and/or how much (or what) the product.

Radio-isotope tracing:

Principle:

The dynamical atoms are recognized by their radiation and, being stanch companions of the inactive atoms of an element, they serve as markers for them.
.
And this is done by labeling the organic compound by radioisotope, so how to label it

1- Radioisotope formation:
14N7 + 1n0 ---- > 14C6 + 1P1

2- throw up it in suitable form:
Ba 14CO3 ----- > 14C6

3- Radiolabelled compounds are synthesized by appropriate radiochemical organic synthesis reactions:

e.g.



: labelled nonyl phenol:

Ba 14CO3 ------ > 14C6H5OH ------ > C9H1914C6H4OH

Analytical methods for detecting radio-labeled compounds:

1- Gas-filled detectors:
e.g.: Geiger-Müller detector

2- Autoradiography (e.g. for Thin Layer Chromatography):
Is image on X-ray film produced by the pattern of decay emissions.

3- glistering detectors:
e.g.: Liquid Scintillation Counting (LSC)

The environmental applications of radioisotopes tracing:

The environmental difficulty : (1) mass balance is missing
