METHOD TO ESTIMATE RISK DEGREE FOR TOXIC ACTION IN CHILDREN Russian patent published in 2002 - IPC

FIELD: medicine, ecology. SUBSTANCE: mercury content in children's urinary portion collected between 6 and 9 o'clock a.m. (x₁), oxalates' content in daily urine (x₂), ratio for mean mercury content in I and VIII portions to mean mercury content in IV and V urinary portions in a sample according to Zimnitsky (y₁), spontaneous urinary crystallization value (y₂), tension index at rest according to Bayevsky (x₃) and the value for pulse and systolic arterial pressure product after dosed physical activities PWC PWC₁₇₀(y₃), detected at 9 o'clock a.m. are determined together with the value of integral index D calculated by the following formula: D = 0,38•(0,25x₁+0,42x₂+0,33x₃)+0,6•(0,20y₁+0,42y₂+0,3y₃), At the value below 65 conventional units (c.u.) no risk of toxic mercury action is diagnosed, at 66-70 c.u. - minimal risk, at 71-90 c.u.- moderate risk, at 91-111 c. u. value -increased risk and at the value above 11 c.u. a high risk are diagnosed. EFFECT: simplified investigation at higher accuracy of estimation. 2 tbl
