A health risk evaluation of the lifetime population risk has been made, by using the US EPA's method of risk assessment.
Several main steps have been conducted :
- a hazard identification, by means of emission analysis and mathematical modeling of air concentration dispersion ; a dose-response evaluation and exposure assessment, and finally - a risk characterization.
The health risk evaluation was conducted, using lifetime reference concentrations and doses.
As risk descriptors were applied : - the individual exposure coefficient (IEC), the hazard quotient (HQ) and the margin of exposure (MOE) - for system toxicants, and the excess lifetime cancer risk (ELCR) - for carcinogens.
The method that was used provides an upperbound estimate, including all possible exposures.
The results showed, that the emissions of hydrogen chloride, phthalates (DOF), nitrogen oxides and most of the organic solvents, released from this chemical plant, are not a source of lifetime chronic health risk for the population of any of the six evaluated residential areas of Rousse.
The rest of the hazardous emissions cause a slightly increased lifetime health risk, which is entirely in the so called'controlled risk zone'-the risk descriptors vary from 1.00 to 5.00.
A number of actions have been prescribed to the plant's government, most of which were realized in the short term.
