The risk factors included inappropriate deposit of hydrocomion and contaminated working clothes (OR = 3.529, 95%CI: 1.408 - 8.848), playing outside frequently (OR = 2.846, 95%CI: 1.513 - 5.352), grandparents being children's guardian (OR = 2.187, 95%CI: 1.187 - 4.029). The protective factors included high frequency of guardianship (OR = 0.408, 95%CI: 0.205 - 0.811), knowledge for poisoning prevention (OR = 0.412, 95%CI: 0.224 - 0.758), washing working clothes in time (OR = 0.435, 95%CI: 0.212 - 0.893), taking health educational courses in school (OR = 0.448, 95%CI: 0.232 - 0.867) and teaching children non-access to toxic agents regularly (OR = 0.462, 95%CI: 0.227 - 0.939).
