Abstract
An effort was made to study the chemical
composition of commonly used eyeliners in Zaria and
Kano, and to study the associated blood lead changes
in patients attending Ahmadu Bello University Sick Bay
and Ahmadu Bello university Teaching Hospital Zaria,
for various medical ailments.
Physicochemical methods were used to analyse the
Kuali samples. The colour (grey and black for white
and black Kuali respectively), physical appearance
(solid), and melting/decomposition point of the Kuali
samples has been noted. The composition of the Kuali
samples had. been ascertained on the basis of classical
analysis, spot tests and atomic absorption spectrophotometry.
The results of the atomic absorption spectrophotometry
revealed the presence of lead zinc, copper, antimony,
tin, arsenic, manganese, cadmium, silver, iron and nickel.
Volumetric and gravimetric analyses were performed
for the estimation of nonmetals. The nonmetals found
were fluoride, chloride, bromide and sulphur.
The concentration of lead in each of the four
samples is low compared with other metals in the
samples. Sulphur has the highest concentration in all
the nonmetals present. Blood-lead concentrations were measured in
thirty patients of whom twenty were using kuali
and ten were nonusers of it. The mean blood lead
concentration of the twenty people using the kuali
is 90.05 ug100ml-1 compared with 29.70 uglOOml-1
in the ten people who are not using the kuali.
