Abstract

|
Metals differ from other toxic substances because they are not destroyed. Metals redistribute continually in the environment by both physical and biological system. Their redistribution in environments can produce potential toxic effect on human body, plants and animals. Heavy metals can be absorbed and concentrated in plants and animals. They can easily incor??porate into food. The plants are highly exposed to heavy metals and minerals because they are always in contact with water, air and soil. The heavy metal contents in herb can be increased by environmental contam??ination. Many metal contamination from environment cause is originated from natural source and human by-product. This study was performed to determine the heavy metal and mineral (lead, arsenic, cadmium, mercury, chromium, cooper, selenium, zinc, iron, manganese, aluminium) contents in herbal extracts at different areas. The concentrations of 11 heavy metals from 21 different areas were analyzed by Inductively Coupled Plasma Mass Spectrometer. Lead, arsenic, aluminium contents of 2 different area samples were higher than 19 other area samples. Generally, herbal extract samples from some specified area have higher values than samples from other areas in many heavy metal contents. This result is considered to be due to exposure to environmental contaminations.
