For mechanical engineering applications mild steel is used for parts that are not subject to high stress. Depending on the analysis, section and form of supply the tensile strength generally falls in the broad range of 350/550 N/mm. When supplied in the bright cold drawn condition higher figures are obtainable, especially on small diameters.

The Centers for Disease Control and Prevention also issued guidelines about ingesting certain folk medicines which contain a high level of lead and may expose people to lead or lead compounds. For example Daw Tway is a digestive aid used in Thailand and Myanmar (Burma). Analysis of Daw Tway samples showed as much as 970 parts per million (ppm) of lead. The Daw Tway samples also contained high arsenic levels, as high as 7,100 ppm.


The hippocampus is a part of the brain involved in learning and memory. The main reasons for lead interfering with learning particularly in children is that it damages the cells within the hippocampus. In rats exposed to lead, structural damage such as irregular nuclei and denaturation of myelin were reported (Mycyk et al., 2005).


The treatment for lead poisoning consists of dimercaprol and succimer (Park et al., 2008). Due to the persistent findings on cognitive deficits caused by lead poisoning particularly in children, widespread reduction of exposure should be mandatory.
