1 2 . 5 . 6 Cadmium <br /> 2 The acute exposure effects range from irritation of the <br /> 3 respiratory tract and progressing to pulmonary edema. The <br /> 4 chronic effects associated with cadmium exposure are anosmia, <br /> 5 stains on teeth, emphysema, kidney damage, and hypochromic <br /> 6 anemia. Cadmium has caused cancer in animal subjects. Cadmium <br /> 7 was found in soil samples from the Site in concentrations <br /> 8 ranging up to 3 .2 ppm. The STLC for cadmium in soil is 1 ppm <br /> 9 and the TTLC is 100 ppm. The LD50 for cadmium is 3-712 mg/kg. <br /> 10 2 . 5.7 Nickel <br /> 11 Samples containing nickel were collected from the Site with <br /> 12 concentrations of up to 37 ppm. The STLC for nickel in soil is <br /> 13 20 ppm and the TTLC is 2 , 000 ppm. The acute effects of nickel <br /> 14 exposure are pneumonitis and skin irritation. Chronic effects <br /> 15 include sensitization of skin and of the respiratory system. <br /> 16 Nickel has been suspected of being carcinogenic in humans. <br /> 17 2 .5.8 Selenium <br /> 18 Selenium was found in soil samples taken from the Site in <br /> 19 concentrations ranging up to 2 .9 ppm. The STLC for selenium is <br /> 20 1 ppm and the TTLC is 100 ppm. The acute exposure effects of <br /> 21 selenium include irritation to eyes, respiratory system and <br /> 22 digestive tract, and produces a garlic smell or odor on breath. <br /> 23 The chronic exposure effects are dermatitis, pallor, lassitude, <br /> 24 irritability, indigestion, giddiness and is suspected of <br /> 25 causing liver damage. The LD50 of selenium is 6 mg/kg. <br /> 26 <br /> 27 <br /> COURT PAPER <br /> STATEOF GLIIORHIA <br /> STD. 113 (REV. ena —6— <br /> % 31199 <br />
