Childhood lead poisoning has been increasingly recognised in the USA where large-scale screening programmes detect some 40 000 cases of undue lead absorption a year. This contrasts with data from the UK where about 100 cases are recognised each year. The situation in other countries is largely unknown, although small surveys have revealed cases from a wide variety of sources. These apparent dis...

This paper reports on the effect of fiber crimp frequency on sound absorption capability of staple polypropylene nonwoven batts. Stuffer box was used to impart crimp to spun tow. Crimping of the tow renders the fibers the required textile applicability. In this work, polypropylene batts composed of staple fibers with linear densities of 9, 14, and 18 denier were employed. Three crimp frequency ...

spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. this review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. the use of an appropriate sample handling technique is a...

Background & aims: Lead poisoning is a global problem and considered to be the most important environmental disease in children. Exposure to even low amounts of lead is dangerous. Lead containing eye make ups due to the long time contact with skin and eye mucosa can lead to blood and eye symptoms. The purpose of this study was to evaluate the amount of lead in powders of kohl in Kerman. Method:...

In this survey adsorption of some heavy metals such as cobalt and lead on montmorillonite and montmorillonite/copper oxide nano-composite is reported. Adsorption percent and adsorption capacity were studied under different conditions such as pH concentration of metal ions amount of clay and interaction time. The results show that an increase in absorption percent and absorption capacity wit...

in order to determine iron and lead content of seminal plasma in water buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls. the semen characteristics were evaluated; its iron and lead content were estimated by atomic absorption spectrophotometer. the iron and lead content of the seminal plasma (mean ± sem) was recorded as...
