Fifty-two public sand pits on children playgrounds in Hannover were investigated for the presence of parasites. A large proportion (63.5%) of these playgrounds were contaminated with parasite eggs. Eggs from Toxocara spp., Toxascaris leonina and other common helminth parasites were found in 55.8%, 9.6% and 26.1% of these playgrounds, respectively. A total of 208 sand samples were collected, and 30.8% of them contained eggs from Toxocara spp. (24.5%), Toxascaris leonina (2.4%) or other common helminths (9.1%). In 45.1% of the Toxocara positive samples, the eggs were embryonated. Eggs from Toxocara spp. were found in 33.0%, 31.0% or 14.0% of samples from districts with low, medium or high numbers of dogs per hectare, respectively.
对汉诺威市儿童游乐场的52个公共沙坑进行了寄生虫检测。其中很大一部分（63.5%）游乐场被寄生虫卵污染。在这些游乐场中，分别有55.8%、9.6%和26.1%检测到了弓蛔虫属、狮弓蛔虫和其他常见蠕虫寄生虫的虫卵。总共采集了208份沙样，其中30.8%含有弓蛔虫属（24.5%）、狮弓蛔虫（2.4%）或其他常见蠕虫（9.1%）的虫卵。在45.1%的弓蛔虫阳性样本中，虫卵已发育。每公顷犬只数量少、中、高的区域，其样本中分别有33.0%、31.0%或14.0%检测到弓蛔虫属的虫卵。
