Dental waste containing high levels of toxic mercury is being pumped into the public sewage system across the country, an academic study shows.
A study of 38 wastewater samples from Abu Dhabi and Sharjah dentists found an average concentration of mercury was about 318 micrograms per litre (µg/l).
High levels of amalgam, used in metal fillings, could harm the community, said Dr Sausan Al Kawas, the head of oral and craniofacial health sciences at the faculty of dentistry at Sharjah University.
"Dental amalgam is of a particular concern because almost half of its mass is mercury, a metal that has well documented health risks."
"According to Dubai Municipality's environmental standards the maximum allowable limit for discharge of mercury containing waste into the sewage system is 10 µg/l," Dr Al Kawas said
Dr Al Kawas said several studies had shown that exposure to mercury may lead to several health complications such as impairment of the developing central nervous system and lung and kidney damage.
The regulations for mercury waste vary by emirate.
However, a spokesperson from the Abu Dhabi Sewerage Service Company (ADSSC) said the level of mercury discharged from sewerage-treatment plants into the water supply had not reached those levels.
"Our equipment allows us to test down to .005 milligrams [5µg] per litre at our two waste water premium plants, and we have never detected that much," he said.
"Requirements for discharging such substances back into the water stream state that substances cannot contain more than .001 milligrams [1µg] per litre."
The spokesperson added that it was possible that the mercury is diluted after it mixes with other waste as it arrives at the water-treatment plant.
Dr Al Kawas said dental clinics should adopt measures to reduce their mercury discharge, such as the use of amalgam separators and filters, improving the design of their discharge system, and cleaning their equipment with high-pressure water cleaning.
The UAE's 1999 waste management law requires that medical waste be disposed of in a manner that does not harm the environment or the community.
It governs the policies set by each emirate's municipalities and health authority. Abu Dhabi's policy, for example, set in 2007, requires that every health care facility provides the required resources for proper waste management at its premises. This includes colour-coded bags and containers with the biohazard symbol for categorising waste.
All staff handling such waste must be continuously trained by the health care facilities on how to follow the health authority's guidelines. The policy also states that there must be a biannual meeting with the outsourced companies which are collecting and disposing of the waste. What was lacking, Dr Al Kawas said, was a specific law that requires dentists to install filters in their drainage systems.
"Because there are no such regulation, there are no penalties being issued. So dentists just dispose of amalgam in the sink. As a result, this enters the sewage system," she said.
Some dentists have stopped using mercury amalgam altogether, preferring alternatives in part because of the difficulty of processing the waste.
Professor Najeeb Al Khaja, secretary general of the Shaikh Hamdan Bin Rashid Al Maktoum Award for Medical Sciences, which supported the study, said the findings were being flagged to the authorities.
"We have informed the health authorities and municipalities so that they can take the required action and prevent mercury from reaching our food and water," he said.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Three tips from La Perle's performers
1 The kind of water athletes drink is important. Gwilym Hooson, a 28-year-old British performer who is currently recovering from knee surgery, found that out when the company was still in Studio City, training for 12 hours a day. “The physio team was like: ‘Why is everyone getting cramps?’ And then they realised we had to add salt and sugar to the water,” he says.
2 A little chocolate is a good thing. “It’s emergency energy,” says Craig Paul Smith, La Perle’s head coach and former Cirque du Soleil performer, gesturing to an almost-empty open box of mini chocolate bars on his desk backstage.
3 Take chances, says Young, who has worked all over the world, including most recently at Dragone’s show in China. “Every time we go out of our comfort zone, we learn a lot about ourselves,” she says.
