Короткий опис (реферат):
Lead is a cumulative toxicant that affects multiple body systems and
is particularly harmful to young children. Lead can affect children’s brain
development, resulting in reduced intelligence quotient (IQ), behavioural
changes such as reduced attention span and increased antisocial behaviour, and
reduced educational attainment [1].
The purpose of this investigation was to study the indicators of cognitive
and behavioural sphere according to the subjective data of Ukrainian children
depending on the level of lead in their blood.
81 children of a random sample aged from 7 to 15 years were examined.
Determination of lead was carried out in heparinized venous blood by the
method of atomic absorption spectrometry with electro-thermal atomization.
The state of the cognitive and behavioural sphere was assessed using survey.
