The effect of temperature and storage time on the migration of antimony from polyethylene terephthalate (PET) into commercial bottled water in Kuwait

Research shows antimony (a toxic heavy metal) can be leached from water bottles made of PET plastics. The rate of leaching is low at a storage temperature of 25°C. However, at temperatures of 50°C and above, antimony release can occur very rapidly. It is likely to approach these temperatures in the Middle East generally and in Kuwait specifically. Therefore, exposure to high temperatures in short period of time during packaging, transportation or storage could produce antimony concentrations that exceed the USEPA MCL of 6 ppb.

When comparing water of the same spring that is packed in glass or plastic bottles made of polyethylene terephthalate (PET), scientists find estrogenic activity is three times higher in water from plastic bottles. These data support the hypothesis that PET packaging materials are a source of estrogen-like compounds. Furthermore, the findings presented here conform to previous studies and indicate that the contamination of bottled water with endocrine disruptors is a transnational phenomenon.

Scientists test for microplastic contamination in 11 globally sourced brands of bottled water, purchased in 19 locations in nine countries. Of 259 bottles, 93% show clear signs of microplastic contamination. Fragments of microplastic were the most common type detected. A small number of particles showed chemical presence of industrial lubricant chemicals. Data suggests the contamination is at least partially coming from the packaging and/or the bottling process itself. The researchers found roughly twice as many plastic particles within bottled water as compared to tap water on average.

The report examines facts and perceptions about bottled water in the global context. It analyses the geography, structure, trends, and drivers of the global bottled water market. It examines the existing knowledge on the quality of bottled water, its impacts on water resources, and its role in plastic pollution. It raises the question of the bottled water industry’s contribution to the sustainable development goal on universal access to safe drinking water. The analysis considered only those types of bottled water that have little or no difference in taste from the tap water provided by regular municipal water supply. It is shown that bottled water is widely consumed in the both Global North and South although prices can be orders of magnitude higher than tap water….

The report argues that while progress toward universal access to safe drinking water for all is significantly off-track, the expansion of bottled water markets slows this progress down, distracting attention and resources from accelerated public water supply systems development. Estimates suggest that less than half of what the world pays for bottled water annually would be sufficient to ensure clean tap water access for hundreds of millions of people without it – for years. There are recent high-level initiatives that aim to scale up financing for the Sustainable Development  Goals, including water-related ones. Such initiatives are an opportunity for the bottled water sector to become an active player in this process and help accelerate the progress toward sustainable water supply, particularly in the Global South.

Stanford pediatrician and arbovirologist Desiree LaBeaud and her colleagues created a community-led mosquito research project in Kenya, where mosquito-borne diseases are common. They found that plastic pollution, including containers and bottles, can serve as major breeding grounds for disease-carrying mosquitoes. In an effort to reduce disease, LaBeaud and colleagues have launched a nonprofit to clean up plastic pollution to prevent continued spread of mosquito-borne diseases.

In this TED Talk, research scientist, activist, author and community organizer, Wallace J Nichols, explains one of four challenges presented to the world at the TEDx Great Pacific Garbage patch event. The challenge to Plastic Product Manufacturers includes: “We challenge you to accept a voluntary cap on non-biodegradable product, and to begin investing resources into developing a new generation plastic product — plant-based, non-toxic in any stage of its existence, biodegradable. We challenge you to own the responsibility of your product till the very end. The packaging you choose to for your products is your responsibility, not the buyer’s. We challenge you to rethink design of products — to reduce both carbon footprint and plastic footprint of your goods shipped around the world.”
