Pesticides, lithium… water that is decidedly less and less drinkable.

More and more official reports, but also scientific studies, warn regarding the pollution of our drinking water and the potential associated health risks. This is the case with potentially carcinogenic pesticide residues and lithium, the consumption of which might increase the risk of infantile autism.

With the spectacular droughts suffered by France last summer, access to drinking water has become a matter of concern for many of us. However, while groundwater tables are still at a critical level (80% of them are classified between “moderately low” and “very low” by the Bureau of Geological and Mining Research), the volume of water available does not is not the only cause for concern. A new ANSES report (National Food Safety Agency) taking stock of emerging pollutants in drinking water, warning regarding its quality and the worrying level of pollutants. Thus, the ANSES researchers listed, in the samples analyzed, the presence of 54 explosive residue, solvent (1,4-dioxane), but especially 157 pesticides and pesticide metabolites in French drinking water.

Among these, it is the metabolite of chlorothalonil R471811 which particularly worries the state agency, ” the pesticide metabolite most frequently found, in more than one out of two samples “. In one out of three samples, its presence exceeds the water quality limit. If no overrun of “ maximum sanitary values was found, it is nevertheless important to remember that the European Union banned chlorothalonil in 2019, because the pesticide has been identified as a possible carcinogen.

Pesticides, but also lithium!

A very recent study, led by researchers at UCLA Health, also warns pregnant women regarding the quality of the water they consume during pregnancy, and the possible impact on the unborn child. Indeed, following analyzing samples from 151 public water distribution networks in Denmark (i.e. half of the national network), combined with data from 50,000 children, the researchers revealed a worrying statistical correlation , although causality cannot be established through these data. Pregnant women consuming tap water with the highest concentrations of lithium ran a higher risk of having their children later diagnosed with autism spectrum disorder. Children, whose mothers were most exposed to lithium through their consumption of drinking water, had, in fact, up to 46% additional risk of suffering from an autism spectrum disorder.

These results raise questions regarding the possible magnitude of a similar phenomenon in France, which deserves to be investigated. Indeed, the median concentrations of lithium in the Danish water analyzed were between 0.6 μg/L (micrograms per litre) and 30.7 μg/L depending on the region. However, in France, tap water contains between 0.1 and 171 micrograms of lithium per liter depending on the region, according to Ineris (National Institute for the Industrial Environment and Risks).

These concentrations threaten to increase worldwide, as the researchers point out, in particular because of water pollution by the wild disposal of disposable batteries, but also the extraction of underground lithium. Pesticides and lithium are added to the long list of molecules that already pollute the waters of the world and of France with nitrates, the different endocrine disruptors, or pharmaceutical releases.
