In order to develop a rapid, simple test to differentiate toxic naphthalene from the less toxic mothball ingredient paradichlorobenzene, both types of mothballs were dissolved in isopropyl alcohol, ethanol, methanol, and turpentine. Twenty-five naphthalene and 25 paradichlorobenzene mothballs were weighed, randomly grouped, and then dissolved in the solvents. After 30 minutes, the mothballs were reweighed. Isopropyl alcohol, ethanol, and methanol did not differentially dissolve the mothballs fast enough to provide a useful test. Turpentine, however, dissolved paradichlorobenzene at a much more rapid rate than naphthalene (P less than .001). After 60 minutes, all of the paradichlorobenzene mothballs had dissolved, while at least 25% of the naphthalene remained. Thus, when confronted with an ingestion of unlabeled mothballs, the physician could gain preliminary information regarding possible toxicity by dissolving a remaining mothball in turpentine for 60 minutes.
为了开发一种快速、简单的测试方法，以区分有毒的萘和毒性较小的卫生球成分对二氯苯，将两种类型的卫生球分别溶解于异丙醇、乙醇、甲醇和松节油中。称取25个含萘卫生球和25个含对二氯苯卫生球，随机分组，然后溶解于溶剂中。30分钟后，再次称量卫生球。异丙醇、乙醇和甲醇对卫生球的溶解速度差异不够大，无法提供有用的测试。然而，松节油对对二氯苯的溶解速度比对萘快得多（P小于0.001）。60分钟后，所有含对二氯苯的卫生球都已溶解，而至少25%的含萘卫生球仍未溶解。因此，当遇到误食未标明成分的卫生球时，医生可以通过将剩余的卫生球在松节油中溶解60分钟来获取有关可能毒性的初步信息。
