While they can be filtered out of drinking water, UK water companies are not required by law to reduce them until they are deemed ‘high risk’.Ĭurrent standards allow concentrations of each individual PFAS at up to 10 times the level considered ‘low risk’, which is 10ng/L (nanograms per litre). In questo articolo imparerai perch e come usarli. Ciascuno restituir un nuovo array basato sul risultato della funzione. Ognuno eseguir un'iterazione su un array ed eseguir una trasformazione o un calcolo. There is growing evidence that some PFAS carry serious health risks including cancer, thyroid disease, and fertility problems as well as developmental defects in unborn children. Map, reduce, e filter sono tutti metodi appartenenti agli array in JavaScript.
