In this study, we investigated the relationships between lead poisoning and intelligence and neurobehavioral changes in 2—4-year-old children, to provide a basis for clinical prevention and treatment measures. A total of children were selected from ten kindergartens with an average age 2. The exclusion criteria we used were 1 birthing problems such as delivery injuries or a low birth weight, 2 neonatal problems such as asphyxia, intracranial hemorrhage, hypoxic-ischemic encephalopathy, and severe jaundice, 3 acquired disabilities including poisoning, cerebral trauma, encephalitis, meningitis, encephalopathy and cerebral injuries following convulsions, and 4 potential factors influencing cognitive development such as malnutrition and inherited metabolic diseases.

Based on these criteria, 96 children were selected to receive blood lead level detection tests. Blood levels of lead were determined by differential potentiometric stripping analysis DPSA. A pre-coated mercury film method was used. Mercury film was pre-plated on the working electrode three times before detection, accumulating to a thickness that enabled it to work for 4 consecutive hours. Amalgam was stripped in a static mode. The samples were detected without digestion. The color of the sample changed from purplish red to yellow after addition of 1.

The color faded after addition of 0. A blank reagent was processed at the same time. The lead content in the blood sample and reagent blank was calculated by a standard addition method, and the absolute difference between the two samples was regarded as the lead content. The parents of the children in both groups were required to fill out a health questionnaire and CBCL for the children. The significance of this investigation and the project requirements were explained to the parents before they filled out the questionnaire, which was collected immediately.

The content of the health questionnaire included approximately 40 questions related to source of exposure to lead, such as the family and social environment, life and health habit, and health conditions of the children. The main risk factors for high blood lead values could be assessed through questionnaire assignment analysis. A number of well-known instruments exist for assessing and categorizing the problem behavior of children. The CBCL is a paper-based questionnaire that presents caregivers with a series of statements that relate to emotional and behavioral problems and competencies, using a 3-point response format to establish the frequency of problem behavior.

This study used the child and teenager psychological test software 2. The development schedules used in this study were a set of four timetables devised by Arnold Gesell — at Yale University to evaluate the physical, emotional, and behavioral development of infants, toddlers, and preschoolers. They describe typical behavior at specific ages in the following areas: ability to adapt, motor functioning, use of language, and social interaction [ 16 ]. All numerical variables in this experiment are expressed as means, standard deviations, minimum values, and maximum values. Enumeration data are expressed by case number, rate, and constituent ratio. Blood lead values between the experimental and control groups were compared using a t -test after logarithmic transformation meet normal distribution.

All test conducted were two-tailed, and the test statistic and its correspondent P value are shown. The log transformed blood lead values ranged 0. Compared with the control group, scores on the measure of developmental quotients of child adaptive behavior, gross motor performance, fine motor movements, language development, and individual social behavior lagged in the children previously exposed to lead, at The examination showed that there were 11 subjects with social withdrawal, 17 subjects with depression, 8 subjects with sleep problems, 6 subjects with atypical body actions, 34 subjects with aggressions, and 7 subjects with destructions among the 50 children in the lead poisoning group, and the rate of abnormal behavior was There were 7 subjects with social withdrawal, 4 subjects with melancholies, 5 subjects with sleep problems, 8 subjects with atypical body actions, 6 subjects with aggressions, and 5 subjects with destructions among the 50 children in the control group, and the rate of abnormal behavior was Among the more than 40 factors we examined in the questionnaire, the risk factors for lead poisoning in children included poor living habits such as finger-sucking, nail-biting, putting foreign objects in the mouth, playing with plasticine, and using colored tableware frequently.

They also included eating puffed food, preserved eggs, and canned food, smoking by a family member, living near a large road, and recent room decoration. Lead is a neurotoxin with no physiological functions in the human body, the ideal concentration of which in the blood is zero. However, because of the prevalence of lead in the environment, lead exists in the vast majority of human bodies.

With the rapid development of industrialization, the production and use of lead, and its accumulative release, there has been a rapid increase in lead levels in the environment [ 17 , 18 ]. Children are very sensitive to lead poisoning because of their metabolism and growth characteristics. Lead can easily penetrate the brains of children because their blood—brain barriers are not fully developed. Research has shown that the blood—brain barrier of newborn rats is highly permeable to lead, and that the younger the subject is, the greater is the permeability. The amounts of lead penetrating the blood—brain barriers of day-old and day-old rats were 2.

Lead poisoning can have continuous damaging effects on children, influencing the development of nervous, cardiovascular, digestive, urological, reproductive, and endocrine systems, with the most sensitive to lead poisoning being the nervous system [ 20 , 21 ]. That lead poisoning can impair the IQ of children has been verified by many Chinese and international scholars. Research by Schnass et al. A high level of lead in the blood has adverse effects on intellectual development in children. A study by Miranda et al. The earliest and most obvious influences of lead on the nervous system of children include neurobehavioral changes except for a decline in intelligence.

It has been verified that lead exposure is associated with childhood behavior disorders [ 25 ]. Behavioral changes in 1—3-year-old children have been associated with low levels of lead exposure, which indicates that behavior disorders should be clinically monitored in children that have even low levels of lead exposure [ 26 ]. Lewendon et al. Mendola et al. Researchers also found recently that antisocial behavior, behavior disorders, and adolescent crime in childhood and adolescence are also related to lead exposure before and after birth [ 29 — 32 ].
