during two successive seasons of 2018 and 2019. The aim of this study was to evaluate the effects of irrigation water contaminated with cadmium on the growth of Polianthes tuberosa plants and the possibility of using tryptophan spray treatments to overcome the effects of cadmium pollution. Corms of Polianthes tuberosa were planted individually in plastic pots (20 cm diameter) filled with 5 kg of sandy soil. The Cadmium contaminated irrigation water treatments were 0,100, 200 and 300 mg/L were applied. The plants were also monthly sprayed by tryptophan at concentrations of 0, 250 and 500 mg/L. The results showed that for vegetative growth parameters there was no significant difference in the interaction between cadmium polluted water of irrigation and foliar spray by tryptophan, while a significant reduction was observed in all parameters after irrigation with cadmium polluted water and a significant increase in vegetative growth parameters was observed after 500 mg/L tryptophan application. For chlorophyll and carbohydrate content, the highest significant value was obtained in plants irrigated with tap water and sprayed with 250 mg/L tryptophan while the highest significant level of cadmium content in leaves and corms was obtained due treatment by 300 mg/L cadmium without application of tryptophan.

In this work, Flame Atomic Absorption Spectrometry (FAAS) was applied for the determination of Cu, Fe, Mg, Mn, Ni, and Zn in twenty -four hair samples. The samples were collected covering different ages and gender. The samples are divided as, seventeen samples from people which assumed to be environmentally healthy (control) and seven samples from different worker's people such as Iron worker, Cement worker and Duco worker (exposed). Samples were brought into solution using HNO 3 and H 2 O 2 . In three example samples the molecular structure of the human hair was studied using Fourier Transformer Infrared Spectrometer (FTIR) in the range of 200-4000 cm -1 .The contamination of the sample was discussed for different samples.
