METHOD FOR GIVING QUANTITATIVE POPULATION HEALTH DAMAGE ESTIMATE AS A RESULT OF ATMOSPHERIC AIR POLLUTION WITH XENOBIOTIC SUBSTANCES Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves measuring substance concentration in surrounding air. Excessive reduced concentration of given xenobiotic substance C_red is determined as C_red = MPC_wz(0.011φ_zi+0.022)- MPC_ip, where MPC_wz is the maximum permissible concentration in working zone air, φ_zi is the MPC_wz excess on lower boundaries of 3.1-3.4 classes taken from table 1, MPC_ip is the maximum permissible concentration in inhabited places air corresponding to normative documents. Damage to population health D_pop caused by given xenobiotic substance is calculated in days per person as D_pop=[1-exp(a*(C_sur- MPC_ip))^b]*365N, where C_sur is the xenobiotic substance concentration in surrounding air in mg/m³, 365 days is the reduction coefficient for making transfer from relative damage to absolute one within a year, N is the population. Empiric coefficients a and b are found by means of calculations done for given xenobiotic substance using least squares method based on relation D_zi=[1-exp(a*(C_sur- MPC_ip))^b]*365 and damage to population health caused by CO in the environment is calculated in days per person as D={1-exp[a*(0.147C_CO- 0.43)^b]}*365N, where C_CO is the CO concentration in the surrounding air in mg/m³, a=-0.0145, b=1.51.

EFFECT: high accuracy in quantitatively estimating damage to population health.
