Nitrate levels in drinking water spur health warning.(NEWS)Meersman, Tom
A water change is a great way to instantly lower the nitrate levels in your aquarium. You should also be mindful that nitrates can be present in tap water. This is a particular problem for those who draw water from wells. If you use tap water for your water change, test for nitrates ...
The spatiotemporal evolution of groundwater nitrate nitrogen levels and potential human health risks indicate that the issue of nitrogen pollution in groundwater in the study area is worsening and needs further attention. The drivers that increased nitrate nitrogen concentrations in the groundwater of ...
Comparison of raw water and finished water samples (same sampling date) showed a significant difference in nitrate levels in municipalities using rivers; municipalities using other surface water or alluvial groundwater had no difference in nitrate levels. A regional aggregation of alluvial groundwater ...
which is the one in intimate interaction with the roots. It is hypothesized that they would be the first in responding to changes in the root system. Here we examined the combined effect of eCO2and nitrate levels on the structure and function of the root-surface-associated (i.e., bacteria...
in rivers and aquifers and (b) evaluate whether NO3−transformations are impacted by key environmental factors, such as temperature, climate, and seasonality. The investigation of the origin of nitrate pollution in rivers and groundwater at the local scale usually requires a deeper consideration of...
analysis showed a negative correlation between Nitrite concentrations anddepth of the aquifer (P-value = 0.034, R = 0.44), ie, with increasing depth there werelower nitrate levels.There was no relationship between nitrate concentrations and the distance of water wellsfrom the sites of wastewater ...
Eleven national and local environmental groups submitted a request Monday to the EPA, saying voluntary measures enacted by state and local regulators have not lowered nitrate levels in the region's groundwater. The groups want the EPA to intervene under the federal Safe Drinking Wat...
The aim of this paper is to present an assessment of nitrates fluxes in the groundwater in Timis County using some direct measurements, as well as their spatial distribution. The presence of the high nitrogen concentrations in soils is a high potential risk for the groundwater and implicitly,...
The formation of cancer-causing chemicals in the gut could be at the heart of understanding how high levels of nitrate in our drinking water contribute to increasing the risk of bowel (colorectal) cancer, New Zealand researchers say. Writing in the latestAustralian and New Zealand Journal of Pub...
