The World Health Organization (WHO) said Thursday the level of microplastics in drinking-water is not yet dangerous for humans but called for more research into potential future risk. In its first report into the effects of microplastics on human health, WHO looked into the specific impact of microplastics in tap and bottled water. “The headline messages to reassure drinking water consumers around the world, that based on this assessment, our assessment of the risk is that it’s low,” said Bruce Gordon, WHO coordinator of water and sanitation. WHO said that data on the presence of microplastics in drinking water is currently limited, with few reliable studies, making it difficult to analyse the results. WHO has called on researchers to conduct a more in-depth evaluation into microplastics and the potential impact on human health. The organisation has also urged a crackdown in plastic pollution to benefit the environment and reduce human exposure to microplastics.
