ABSTRACT: 
In this work the optical-spectrometric data on optical reflectance spectra taken from spill ail and pure/mazut-contaminated soils are 
presented. 
1.INTRODUCTION 
Sudden increase in oil production volumes has given rise to 
ecological problems throughout the Kazakhstan oil filed areas. 
In particular, some problems are caused by spill ails, soil mazut 
contamination and man-caused waste pollution of lands. As a 
result, a necessity in land monitoring by remote sensing 
technique occurs. 
Reliability of the data obtained as a result of remote sensing is 
assessed usually by an extent of coincidence between the solar 
emission reflectance spectra taken from natural objects under 
study (samples of soil, vegetation, water systems, etc.) by 
means of the space-base spectrometric systems and the 
corresponding spectra taken by field-spectrometry instruments 
in special subsatellite test sites (see, e.g., [1]-[3]). That’s why 
remote sensing techniques are used successfully when solving 
ecologic problems throughout the regions provided by 
reflectance optical spectrum libraries for both the 
conventionally pure and man-caused contaminated natural 
objects. 
In this work we make an attempt to assess, basing on ground 
spectrometry data, opportunity for control of spill ail, the soil 
mazut-contamination level and search for the unapproved man- 
caused waste storage/disposal places in the oil fields by remote 
sensing techniques 
2. INVESTIGATION TECHNIQUE AND OBJECTS 
In view of spectrometric studies, we have chosen three ready 
test areas. 
The first area represents fresh spill ails around the bad-immured 
oil well. 
The second area is the territory of many-year storage of dirty 
oils and man-caused waste. This area is characterized also by 
enhanced level of radioactive emission. 
The third area represents old spill ails around desolate oil well, 
which was closed more than ten years ago. In this area the spots 
are available of heavily mazut-contaminated soils covered with 
layers of stony oil slag as well as a region of weak mazut- 
contaminated soils along the border between spill ail and 
conventionally pure soils. 
I 
Sample spectrometric studies were carried out by means of the 
spectrometers FTIR 8300 (Japan), Specord M-80 (Germany) 
and C®-256 UVI (Russia). 
3. EXPERIMENTAL RESULTS AND DISCUSSION 
n the test areas we took, in total, several dozens of reflectance 
spectra from the samples of liquor and solid oil as well as soils 
contaminated by mazut to various levels. 
I 
n figure 1 several reflectance spectra taken from spill ail 
samples, mazut-contaminated soils and rather “pure” soils 
(coastal alt-marshes) are given as an illustration.

“It should be marked that the presented spectra are similar to 
those obtained at field conditions by portable radiometer. Figure 
| shows that optical reflectance spectra taken from coastal salt- 
marsh and spill ails differ strongly in the intensity; and this 
circumstance can be used to identify spill ails and mazut- 
contaminated areas. 
The obtained optical reflectance spectra were used to determine 
coefficients S and Q, presented in Table 1. The coefficient S is
