“…The main objective of the present study was to investigate the mutagenic potentials of drinking water from different zones of Tehran, to compare two most polluted seasons (summer and autumn) (Ziarati et al, 2012) and its combinational mutagenic effects with highly consumed flavored black tea bags in Tehran, the capital of Iran by Ames mutagenicity assessment which has been considered as a rapid, cheap, predictive and reliable method (Rincon-Bedoya et al, 2013).…”

“…Many studies have emphasized a basis for health risk assessment of drinking water to strength current authorities and reduce the possible health risks arising from trace-level hazardous pollutants in drinking waters (Bain et al, 2014). Tehran the capital city of Iran is a highly polluted city and the concentration of contaminants in air, drinking water and other environmental resources varies according to the geographical location, season (Ziarati et al, 2012) and many other factors (Karyab et al, 2013).…”

Diseases related to water impurities may present as major public health burdens. The present study aimed to assess the mutagenicity of drinking water from different zones of Tehran, and evaluate possible health risks through making tea with tea bags, by Ames mutagenicity test using TA 100, TA 98 and YG1029 strains. For this purpose, 450 water samples were collected over the period of July to December 2014 from 5 different zones of Tehran. Except for one sample, no mutagenic potential was detected during these two seasons and the MI scores were almost normal (≤1-1.6) in TA 100, TA 98 and YG1029 strains. Although no mutagenic effects were considered in TA 98 and TA 100 in the test samples of our three evaluated tea bag brands, one sample from a local company showed mutagenic effects in the YG1029 strain (MI=1.7-1.9 and 2) after prolonged (10-15 min.) steeping. Despite the mild mutagenic effect discovered for one of the brand, this cross sectional study showed relative safety of water samples and black tea bags in Tehran. According to the sensitivity of YG1029 to the mutagenic potential of water and black tea, even without metabolic activation by s9 fraction, this metabolizer strain could be considered as sensitive and applicable to food samples for quantitative analysis of mutagens.

Rice is one of the most widely consumed grain crops (besides wheat and maize) in Iran and various countries. Currently, more and more rice is found to be contaminated with heavy metals, which can have a negative impact on human health. The current study aimed to investigate the impact of coffee bean waste (CBW) and Rice Husk ( RH) as bio-adsorbent in reducing Lead, Arsenic, Cadmium, and Nickel in rice (Oryza Sativa). 950 rice samples were collected from various markets in Tehran to extract the heavy metal content in raw, rinsed, soaked with adsorbent, and cooked and drained rice, determined and measured by wet digestion method. Final concentrations of heavy metals in rice samples were analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy according to AOAC International Standards. Batch adsorption experiments were carried out to evaluate the effect of adsorbent dosing, sample state, and ionic strength of solutions on the adsorption of heavy metals onto bio-adsorbents collected simply from legumes and homemade waste at room temperature and then dried at 65 C0 and ground to size mesh 80-100 microns. Arsenic was not found in the samples studied. The cadmium content of the samples was removed through cooking and treated with a mixture of certain percentages of CBW and RH. The content of Lead and Nickel decreased significantly (p<0.05) in all cooking methods. The weekly cadmium intake in bulk and unprocessed packaged rice samples is higher than that of Iranian national standards. Still, with the new eco-friendly detoxification method, there is no risk under any cooking conditions and no food contamination. The current research findings indicate that Food/Agro waste can be utilized profitably in processing rice containing heavy metal ions.
