ABSTRACT
In the present study the concentration, of lead particles and fumes in the working environment of a printing industry were throughly investigated. The blood lead, urinary lead and ALA of 106 exposed workers and 20 non-exposed workers, as a control group, were measured. Results showed that workers in the departments where lead materials are handled are mainly exposed to lead fumes which represent >80%of total lead exposure moreover, it was found that exposed to >20 micro/g/m[3] [8 hrs] atmospheric lead in both forms of respirable particles and vapour can result in high blood level. ALA was found to be a reliable indicator of lead effect. The present investigation points out that the TLV of 0.20 mg/m[3] is a non-realistic level since the exposure to atmospheric lead in a range between 20-37 micro g/m3 results in a high blood lead and subsquently a higher level of ALA in urine. Consequently, it is suggested to lower the TLV for lead exposure especially where lead fumes exist. Conclusions and special recommendations were given
