The observed mean as well as the highest single-point values for both nitrates and nitrites in drinking water are well below WHO's maximum acceptable concentration (MAC), of 10.0 mg/L nitrate as NOsub3/sub–N and 3.0 mg/L nitrite as NOsub2/sub–N. However, the levels of both species...
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...
💧 For infants who are bottle-fed, nitrate poisoning can happen when nitrate contaminated drinking water is used to dilute formula. 如果用硝酸盐污染的饮用水稀释奶粉喂养婴儿,就有可能导致硝酸盐中毒。 Diet 饮食 💮 There is an allowable daily intake set for nitrates in the diet. 硝酸盐在饮食中...
(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, ...
Nitrates and Nitrites in Food and Water || Nitrate in water The presence of nitrates and nitrites in drinking water is one of the major concerns for the risk assessment of population exposure. This study refers to the risk exposure of the Frcaa inhabitants to the nitrate and nitrites in well...

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 concentration range for the nitrates in the river water samples is 1.74±0.13 – 115±3.27 mg/L...
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 (NO\n\nand a UV sensor for the detection of the optical power after the ...
Nitrites in water were determined by direct injection, without further pretreatment of the sample. The analysis of nitrate was carried out with the same procedure used for nitrites, the difference being the introduction of a cupperised cadmium reactor which reduces quantitatively nitrates to nitrites ...
