This research was conducted to evaluate the risk of heavy metals and pesticides in samples of natural source tea (gardens) and different local market brands. High Performance Liquid Chromatography was used to detect pesticides, Bifenthrin, Lambda chalothrin, Imadachloroprid, Dichlorovas, Glyphosate and Emamectin. Heavy metals such as Zinc, Iron, Chromium, copper, manganese and cobalt were determined by atomic absorption spectroscopy. The value of HRI and THQ was still calculated for some exceeded samples. From results obtained some of the tea samples were contaminated from with heavy metals i.e.,... |
