The effects on human health of raised nitrate and nitrite levels in drinking water are currently unclear. Objectives We conducted a systematic review of peer-reviewed literature on the association of nitrate and nitrite in drinking water with human health with a specific focus on cancer. Methods ...
When excess nutrients – such as nitrate and phosphorus – wash into a body of water, harmful algal blooms (HABs) are often the result. These blooms can produce dangerous toxins and cause a drop in dissolved oxygen, resulting in fish kills. Algal blooms in water bodies that serve as drinkin...
Is nitrate harmful to humans? Are the current limits for nitrate concentration in drinking water justified by science? There is substantial disagreement among scientists over the interpretation of evidence on the issue. There are two main health issues: the linkage between nitrate and (i) infant ...

Research efforts have been made for detection and removal of nitrates from drinking water. A handheld sensor measurement system has been developed for measuring nitrate ions in water, which is based on molecular modeling and computational simulation. The model also optimizes themolecular architecture, ...
The presence of high levels of nitrates in water is known to cause harmful physiological effects in humans. Consequently, potable water supplies are typically treated in an ion exchange process to at least reduce the nitrate levels. During some point in an ion exchange process, it is necessary ...
More recently, reports of nitrate in drinking water, especially at levels higher than 50 ppm, have been associated with other health effects other than methemoglobinemia. This toxicological review provides an update on the health effects of nitrate with a focus on methemoglobinemia, reproductive ...
Characterization of the nitrate-functionalized patch in terms of mechanical properties (c) and water contact angle (d). Data are expressed as mean ± SD, n = 3 independent repeats. Full size image When the patch was implanted subcutaneously in rats, the total NOx within the patch was ...
Nitrate is often regarded mainly as a water pollutant and its presence in the diet of man is seen as an unfortunate consequence of the use ofnitrogen fertilizersinagriculture. Increasingly stringent regulations to limit nitrate intake suggest that nitrate has wholly undesirable effects including formatio...
effects of nitrates on cardiac dynamics demonstrated a reduction in ventricular filling due to a decrease invenous returnresulting from an increase in venous capacitance[24]. Thus,venodilatationreduces bothend diastolic volumeand diastolic wall stress, resulting in a decrease in oxygen consumption and ...
