Evaluation of Heavy Metals Level in Blood, Plasma and Urine of Adolescents with Aggressive Behaviour (Part-2)

In children with asymptomatic heavy metal poisoning caused by prolonged low dose contact, non specific symptoms such as behavioral disorder, difficulty in learning, and tendency to violence are seen. Exposed to heavy metals in the prenatal or postnatal period, there is an increased frequency of social introversion, depression, atypical body movements, neurological problems, aggression, sleep disturbance, even substance abuse and forensic incidents.

We applied Madran ’s Aggression Scale (2012) to 228 adolescents aged between 13-19 years . Blood, plasma and urine heavy metal levels of the participants were measured with ICP MS which is one of the most sensitive methods in quantitative measurements of heavy metals today. A total of 228 participants, 55.7% (n = 127) of the participants were women, and 44.3% (n = 101) of the participants were men, and the average age of the participants was 15 years.

According to result of analysis, aluminum blood (r =0,30, p <.01), aluminum plasma (r = 0,22, p <0,01), aluminum urine (r = 0.34, p <.01), arsenic blood ( r = 0,35, p <0,01), arsenic urine (r = 0,33 , p <0,01), chromium blood (r = 0,38, p <0,01), chromium plasma (r = 0,33, p <0,01) and chromium urine (r = 0,39, p <0,01) were found to be positively correlated with general tendency to aggression. Accordingly, as the level of aluminum (blood, plasma, urine), arsenic (blood, urine) and chromium (blood, plasma, urine) increases, the general tendency to aggression increases. In general, levels of cobalt in blood, plasma and urine and nickelin plasma were not found to be correlated with tendency to aggression.
