Abstract
The determination of metal traces is very important because they are involved in biological cycles and indicate high toxicity. The objective of the present study is to measure the levels of heavy metals and mineral ions in medicinally important plant species, Citrus sinensis and Psidium guajava. This study investigates the accumulation of Copper (Cu), Zinc (Zn), Cadmium (Cd), Aluminum (Al), Mercury (Hg), Arsenic (As), Selenium (Se) and inorganic minerals like Calcium (Ca) and Magnesium (Mg) in C. sinensis (sweet orange) fruit peel and P. guajava (guava) leaf, to measure the levels of heavy metal contamination. Dried powdered samples of the plants were digested using wet digestion method and elemental determination was done by atomic absorption spectrophotometer. Results are expressed as mean ± standard deviation and analysed by student's 't' test. Values are considered significant at P < 0.05. The results were compared with suitable safety standards and the levels of Cu, Zn, Cd, Mg and Ca in C. sinensis fruit peel and P. guajava leaves were within the acceptable limits for human consumption. The order of concentration of elements in both the samples showed the following trend: Mg > Ca > Al > Zn > Cu > Cd > Hg = As = Se. The content of Hg, As and Se in C. sinensis fruit peel and P. guajava leaves was significantly low and below detection limit. The content of toxic metals in tested plant samples was found to be low when compared with the limits prescribed by various authorities (World Health Organization, WHO; International Centre for Materials Research, ICMR; American Public Health Association, APHA). The content of Hg, As and Se in C. sinensis fruit peel and P. guajava leaves was not detectable and met the appropriate safety standards. In conclusion, the tested plant parts taken in the present study were found to be safe.
