Task №1: to decide a case study (a competence is knowledge, practical and legal skills)

The aim of the stage of hazard identification is establishment of possible threat for a health in the region of КOGCF from the educed chemicals taking into account their ability to harm to the organism.

 

The basic task of the stage is a choice of priority, indicatory chemicals, that allows with sufficient reliability to describe risk levels for the health of population and sources of their origin.

On the first stage with the purpose of exposure of chemicals potentially able to affect health of population, an analysis was conducted taking into account technological processes, the total volumes of extras are certain at volley and regular modes (т/year and g/с), sizes of extras of harmful substances.

According to the form of taking of inventory, the extras of contaminants from the enterprises of Karachaganak Oil and Gas Condensate Field come true by 272 sources among that 164 the organized point and 108 unorganized. All analysis is presented 44 contaminants, thrown out in atmospheric air (Table 1).

Consequently, on the stage of authentication of danger final judgement about priority of the selected substances is done after the preliminary calculation of the forecast levels of contamination by means of design of dispersion of components of extras.
