Microplastics contained in drinking water pose a “low” risk to human health at current levels, but more research is needed to reassure consumers, the World Health Organization (WHO) said on Thursday (August 22).
Studies over the past year on plastic particles detected in tap and bottled water have sparked public concerns, but the limited data appears reassuring the U.N. agency said in its first report on potential health risks associated with ingestion.
Microplastics enter drinking water sources mainly through run-off and wastewater effluent, the WHO said. Evidence shows that microplastics found in some bottled water seem to be at least partly due to the bottling process and/or packaging such as plastic caps, it said.
It added however that the current and available studies on the toxicity of plastic parts are limited, and also have not used standardized methods enabling scientists to have reproducible and comparable metrics, and that more studies are needed to be more conclusive on certain of the issues.
Microplastics pose three threats, a physical one, a chemical and the third is about bacterial colonization.
The majority of plastic particles in water are larger than 150 micrometers in diameter and are excreted from the body, while the vast majority of smaller ones are likely to be excreted too, there still remains concern. WHO technical experts reported that more research needs to be conducted to know more about what is being absorbed, the distribution and their impacts.
The chemical hazard, experts have looked at the concentrations found in marine microplastics and chose a worst-case scenario saying we would ingest the highest possible concentrations. According to WHO, whatever the chemical, the exposure level was a lot safer than any threshold of risks.
Bacterial colonization, health experts say there are so many particles in the environment bacteria might adhere to, that microplastics would make a negligible contribution to any microbioflora that would be released and pose a risk.
For this report, however, despite the flaws, they say they worked with worst-case scenarios and are confident that the risk would remain low should some data change.
The WHO recommended for consumers to keep on consuming tap or bottled water, provided it is correctly treated, and didn’t recommend for any regulations to be put in place. It also called for more studies, investigating the potential cumulative effects of the ingestion of microplastics present in food, air, water.
The biggest overall health threat in water is from microbial pathogens —including from human and livestock waste entering water sources — that cause deadly diarrhoeal disease, especially in poor countries lacking water treatment systems, the WHO said.
Some 2 billion people drink water contaminated with faeces, causing nearly 1 million deaths annually, Gordon said, adding: “That has got to be the focus of regulators around the world.”
Plastic pollution is so widespread in the environment that you may be ingesting five grams a week, the equivalent of eating a credit card, a study commissioned by the environmental charity WWF International said in June.

MANILA, Philippines – Manila Mayor Francisco “Isko Moreno” Domagoso on Thursday ordered the conduct of intensified inspection in public markets following the seizure of thousands of kilograms of “botcha” or spoiled meat in the capital city since July this year.
Report from the Manila Veterinary Inspection Board presented on Thursday showed that since July 1, around 2,689 kilograms of spoiled beef shanks, pork and chicken meat were seized by authorities from different areas in Manila.
Hot meat are food items that did not pass proper inspection and are deemed unsafe for consumption.
Mayor Isko also ordered concerned local agencies to set up checkpoints in the entry and exit points of Manila Harbor to prevent the entry of spoiled meat to the city.
He also urged the public to be cautious and observant when buying meat products.
Domagoso also called on meat vendors to join in the city government’s campaign against botcha and to make sure to only sold food products from accredited meat establishments. (RRD with details from Harlene Delgado)
According to their research several extracts from horn snails (Telescopium telescopium) may prevent angiogenesis or formation of blood vessels from pre-existing ones.
“By preventing this process to occur, cancer cells are starved and do not grow and spread,” according to the study.
The study was published in journal Acta Medica Philippina last month.
“This study evaluated the potential antiangiogenic activity of Telescopium telescopium or locally known as Bagongon. It is highly abundant in the country and consumed as food by the locals,” the study further reads.
