If we keep wasting water at the current rate, there will be a severe shortage of water by 2050, a study has suggested.

According to a research by  Anthony Parolari from Duke University, the global demand of water will  surpass the supply if the population keeps burgeoning in the current manner by 2050. The water levels are diminishing and the consumption trend is a worrying site.

“But if population growth trends continue, per-capita water use will have to decline even more sharply for there to be enough water to meet demand,” said researcher Anthony Parolari from Duke University.

The researchers used what is called a delayed-feedback mathematical model to analyze historic data to help project future trends.

“The world population is projected to escalate up to 96 billion till 2050. What strains us is how would we comply to the growing needs of every new born? How much more water can we supply? We might be reaching an alarming state where the efficiency measures are no longer sufficient and water scarcity either impacts population growth or pushes us to find new water supplies,” researches said.

“For every new person who is born, how much more water can we supply? The model suggests we may reach a tipping point where efficiency measures are no longer sufficient and water scarcity either impacts population growth or pushes us to find new water supplies,” Parolari noted.

Water recycling, and finding new and better ways to remove salt from seawater, are among the more likely technological advances that could help alleviate or avoid future water shortages.

New Device to Detect Low Fluoride in Water

The World Health Organisation (WHO) has set 1.5 mg/litre as the maximum limit for fluoride in drinking water

Researchers have built a new device to accurately measure fluoride concentrations using only a few drops of water with even low contamination, finds a new study.

In India, low concentration of fluoride – below 1.5 mg/litre – is used to prevent tooth decay and strengthening of bones. But if it touches above 2 ppm it could cause serious health issues, like dental and bone disease, especially in children and developing foetuses.

That’s where the device – SION-105 – comes in. It’s portable, considerably cheaper than ones in use now, and can be used on-site by anyone. In addition, it is luminescent by default, but darkens when it encounters fluoride ions.

Measuring fluoride at low concentrations with sufficient accuracy is expensive and requires a well-equipped chemical lab.

Kyriakos Stylianou at EPFL Valais Wallis in Switzerland said SION-105 detects fluorides by adding only a few droplets of water and by monitoring the colour change of the metal-organic frameworks (MOFs).

The study was published in the Journal of the American Chemical Society.

Adding fluoride to water has been a common practice in many countries, including the US, Australia, Brazil, Malaysia, India and Vietnam, especially in low concentrations – below 1.5 mg/litre.

The World Health Organisation (WHO) has set 1.5 mg/litre as the maximum limit for fluoride in drinking water. (IANS)
