Sediment phosphorus fractionation, adsorption kinetics, and adsorption isotherm characteristics were studied in two rivers, Muyang River and Lengshui River in China, emptying into a drinking water source reservoir, Songhua Reservoir. The relationship between phosphorus fractions and adsorption characteristics ...
High nitrate level in drinking water has also been implicated, but not incontrovertibly, in the incidence of cancers of the digestive track. Besides the possible adverse human health effects associated with high nitrate intake, evidence is emerging of its potential benefits in cardiovascular health ...
For phosphorus, regional actions including reducing emissions from wastewater to aquatic ecosystems, are required to deliver local impacts including the provision of clean drinking water. This is because the effects of carbon emissions are moderated by atmospheric processes, and the benefits of reduction...
Chemical activation of hydrochar, such as KOH activation, has received popularity in recent years as it makes hydrochar more efficient than its raw form in removing phosphorus from water [56]. However, KOH activation has both economic and environmental challenges and thus is deemed not feasible ...
As these blooms die and decompose, dissolved oxygen in the water decreases (Sharpley and Rekolainen, 1997), which can negatively impact the aquatic ecosystem (Pierzynski et al., 2000). Such blooms contribute to fish kills, the unpalatability of drinking water, and the formation of trihalo...
According to world health organisation (WHO), the tolerance limit of nitrate content in drinking water is 40 mg/L and the phosphate content is < 0.5 mg/L9, 11. According to U.S. Environmental Protection Agency (USEPA) and WHO maximum contaminant level goal in drinking water have set ...
However, both herbicides and heavy metal ions pose serious threats to aquaculture production, food health, and the natural water environment. Previous studies on the ecology of filamentous algae have presented diverse perspectives regarding the factors influencing their occurrence, including substrates [9]...
Therefore, agricultural production is highly dependent on the addition of large quantities of P in the form of different molecules that are easily available for the plants (water soluble phosphate fertilizers; WSPF). The P in these fertilizers is derived from mines of sedimentary deposits of ...
Health effects of phosphorus Phosphorus can be found in the environment most commonly as phosphates. Phosphates are important substances in the human body, because they are a part of DNA materials and they take part in energy distribution. Phosphates can also be found commonly in plants. Phosphat...
Effects on Human Health HABs can harm humans either through direct contact with the skin or by digestion. Coming into contact, often by swimming, with these waters can cause the development of irritation of the lungs, eyes, skin, and nose. However, it is the ingestion of this water that ...
