The merchant market for chi orohydrin s is small, primarily for specialty appHcations. Ethylene chlorohydrin is sold ia the United States by BASF Corp., Parsippany, N.J., available ia 230 kg net lined steel dmms. Glycerol monochlorohydrin (3-chloro-l,2-propanediol) is available from Dixie Chemical Co., Houston, Tex., in lined steel dmms (227.3 kg net) from Raschig Corp., Richmond, Va. and from Henley Chemicals, Inc., Montvale, N.J., ia steel dmms (240 kg net). Glycerol dichi orohydrin (l,3-dichloro-2-propanol) is not currentiy being produced for the U.S. merchant market but has been available ia the past at a selling price of 5—6/kg.

Table I indicates the sample size and population estimates of preschoolers by study area and stratum. Though all strata for the Dixie site are shown, at the Dixie site the configuration and location of the major traffic artery in relation to the smelter site did not allow analysis of the contribution of vehicular traffic to soil lead. The contribution of the smelter to soil lead levels was possible at the RSR site and the reference site.

Table II shows that houses in the reference area contained significantly more lead paint than houses around either the RSR or Dixie site, while the RSR area contained more than the Dixie area. Based on a visual inspection, the paint on the walls and trim areas was Intact and was not peeling, flaking, or otherwise deteriorating.

Table XIV shows the estimated population of children In the RSR and Dixie sites by race, distance from the smelter sites, and distance from traffic density.

The mean blood lead level of black children at the Dixie site was found to be only slightly higher (15.8 g/dl) for those living within 0.5 mile of the smelter as compared to those living within 0.5 - 1 mile (14.9 g/dl). The three non-black children whose blood-lead levels were 30 g/dl were siblings in a family where a parent worked at Dixie Metals (Tables XVIII and XIX). 

Table XVIII. Mean Blood-Lead Level by Race, Traffic, and Distance from Dixie Site...

Less than 0.5 percent of the black children at the Dixie site were found to have lead toxicity (Table XX). As previously noted, the three non-black children (6.6 percent of non-black children) found to have lead toxicity were siblings In a household where the father had an occupational exposure to lead. 

Tables XXI and XXII show that for the RSR site the differences In mean blood-lead levels and proportion of children with lead toxicity remain evident even when other sources of potential exposure (as determined from the questionnaire) were taken Into consideration Tables XXIII and XXIV show this Is not the case for the Dixie site ...

Table XXIV. Percent Lead Toxicity by Distance and Other Potential Sources of Exposure for Dixie Site...

When the Dixie site is compared to the reference area, proximity to the smelter (within 0.5 mile) contributed 1.85 pg/dl to the mean blood-lead level. The potential contribution of traffic density could not be determined because of the configuration of the roadway and the distance of the roadway from the smelter site. Although an elevated mean blood-lead level was found for children living close to the Dixie site, the increase was not as great as observed in the RSR site and the few children found to have lead toxicity, as defined previously, appear to have lead exposure due to occupation of parents.
