Infection is the outstanding feature of a low white count appearing when counts are in the range of 1000 - 1200 (S-4,200 to 10,000) and may lead to death.

Results and Discussion Models and parameters The best fits for both models lead to similar peak dates and analogous overall shapes.

Strangely enough, it was the industry's search for an answer to the cause of acroosteolysis that eventually lead to the discovery of the carcinogenic risk of vinyl chloride.

The results are shown as follows: Ammonia nitrogen, as N Total Kjeldahl nitrogen, as N Organic nitrogen, as N Nitrate nitrogen, as N Nitrite nitrogen TOC Oil and grease Lead Ethylene glycol Phenol Fluoride Sample No. and Description LCVCP-I-72-44 ' LCVCP-I -72-45 "As Is" Effluent Water "Acidified" Effluent Water ppm 2 10 8 <0.5 <0.01 461 4 0.13 ppm 10 ppm <10 ppb Ammonia nitrogen, as N Total Kjeldahl nitrogen, as N Organic nitrogen as N Nitrate nitrogen, as N Nitrite nitrogen, as N TOC Oil and grease Lead Ethylene glycol Phenol Fluoride Mercury LCVCP-I-72-46 "As Is" Effluent Water ppm 9 10 1 <0.5 <0.01 469 2 LCVCP-I-72-47 "Acidified" Effluent Water <0.10 ppm 8 ppm <10 ppb Sample LCVCP-I-72-43 previously reported to have <1 ppb mercury was re analyzed using a different instrument.

This concept leads to a much more meaningful interpretation of the dose-response data and permits more meaningful extrapo lations of that data.
