conclusions the results of this study show that it is possible to remove nitrate, and its intermediates from waste water. regarding the desirability of the process, the field scale study is proposed. results the results showed that by applying electric current of 0.14 a for 120 minutes, the nitrate content would reduce down to 97%. the obtained r2 for the nitrate removal model was higher than 0...
Withania somnifera (Ashwagandha), also known as Indian Ginseng, is a well-known Indian medicinal plant due to its antioxidative, antistress, antigenotoxic, and immunomodulatory properties. The present study was designed to assess and establish the cytoprotective potential of Ashwagandha leaf aqueous extract against lead induced toxicity. Pretreatment of C6 cells with 0.1% Ashwagandha extract sh...
Backgrounds and Objectives: Nitrate is a water contaminant that can cause health problems in human and animals, in addition to eutrophication of the water body. So, Nitrate-contaminated water may be treated by treatment systems. In this study, hydrogenotrophic denitrification using hydrogen produced by Fe0 as an electron donor to nitrate removal was evaluated to assess the feasibility of employ...
Background and Objectives: Bottled water is a main beverage at many developed and developing countries. It can be polluted with chemical agents. One of these agents is nitrate which affects the safety of bottled and mineral water and cause healthy effects on consumer health. Today;aposs consumption of bottled water get a grate develop, thus infer of the quality of this matter is compulsive for ...
Nitrate and nitrite in drinking water is harmful for human health, specialy when its amount is more than the standard level.The purpose of this study include measuring concentration of nitrate and nitrite in &n...
Introduction: Water is vital for life. Its inadequate quality causes significant effects on the health condition of the individuals and society. Groundwater is one of the sources of Nitrate that level over standard limits may lead to several health problems such as hemoglobin metabolism and the formation of nitro amino compounds. Therefore, the aim of this study is determining ...
We studied peripheral lymphocyte HPRT variant frequency and endogenous nitrosation in human populations exposed to various nitrate levels in their drinking water. Four test populations of women volunteers were compared. Low and medium tap water nitrate exposure groups (14 and 21 subjects) were using public water supplies with nitrate levels of 0.02 and 17.5 mg/l, respectively. Medium and high w...
Background & Aim: Groundwater is a major source of drinking water in Zahedan city; however, its quality is affected by high human activities and leads to the increased level of nitrate. This study was conducted to evaluate the nitrate concentration in water resources compared to the standards and also evaluating its Non-Carcinogenic Risk (Hazard Quotient: HQ) in Zahedan city. Methods: In this ...
The circadian rhythms in bioluminescence and photosynthesis in Gonyaulax polyedra suspended in unsupplemented sea water have been compared to the same rhythms in f/2, an enriched seawater medium. Cells suspended in sea water for 2 days in continuous light (450 microwatts per square centimeter) showed significantly shorter circadian periods and lower amplitudes than did cells in f/2 medium (a pe...
Introduction: High prevalence of liver disorders has been observed in postmenopausal women. This study aims at determining the effects of long-term, low-dose nitrate administration on serum levels of liver enzymes, including aspartate aminotransferase (AST), alkaline phosphatase (ALP), and alanine aminotransferase (ALT) in ovariectomized rats. Materials and Methods: Female Wistar rats were divi...
