The levels of nitrates and nitrites in drinking water, river water and factory effluents from three major cities in Swaziland were determined by a pre-calibrated colorimetric method. The pooled mean concentratio
The study presents the spectral analysis for nitrates and nitrites monitoring for water samples-drinking water, underground water and surface water. This overview on the most common inorganic nitrogen compounds (nitrates and nitrites) helps us understand their toxic effects on human health.RADU...
(over 45 ppm nitrates in drinking water, over 0.5 g nitrate/100 g D.M fodder/diet), the factors that influence nitrates/nitrites toxicity ( species, age, rate of feeding, diet balance especially energetically), pathological effects and symptoms (irritation and congestions on digestive tract, ...
And how many realize that naturally occurring nitrates or nitrites are no safer than added nitrates or nitrites? Hold the bacon, ham, & hot dogs However, nitrite and nitrate levels in drinking water are still an important contamination issue in the world. Total Nitrite and Nitrate Levels in Pu...
The presence of nitrates/nitrites at high concentrations in groundwater resources represents an important issue for human health and a great environmental risk. The purpose of this study is to present an analysis of data collected by monitoring nitrates/nitrites concentrations in six counties from the...
Cailean D, Teodosiu C, Volf I, Ciobanu (2009) Occurrence and associated risk of nitrates/nitrites in the ground waters from the north-eastern part of Romania. In: Simeonov LI, Hassanien MA (eds) Exposure and risk assessment of chemical pollution - Contemporary method- ology. Springer, The...
nitrites/nitrates; food; health effect; nitrosative stress; processed meat Graphical Abstract1. Introduction Nitrate and nitrite ions are widespread in the environment and occur naturally in plant foods (vegetables) and water. The contribution of drinking-water to nitrate intake is usually low (less ...
First of all, it causes soil and water pollution, and the final effect is that we can find nitrates and nitrites in drinking water and food. Nitrates in groundwater can lead to the contamination of drinking water, posing risks to both ecosystems and human health. In aquatic ecosystems, high...
In a laboratory construction for heterotrophic biological denitrification of drinking water treatment, the formation of nitrite, the potency of nitrosation and the genotoxic activity were tested. Parameter as nitrate concentration, the water flow rate in the system, nitrite and morpholine addition and the...
This paper presents the development of a portable, cheap and easy to use electronic device which can detect the concentration of nitrates and nitrites in drinking water. The device is based on the property of nitrates (NO3) and nitrites (NO2) to absorb ultraviolet light. The absorption peak ...
