The Sunday Times, 3 April 2016:

It appears diesel exhaust fumes are linked to psychological problems in children, including attention deficit hyperactivity disorder, depression and anxiety.There is also data showing an IQ deficit of approximately 4 points among children highly exposed to particulates and oxides of nitrogen. Many parents will prefer to bring up their children in the country, as did I, to avoid exposure to another potent neurotoxin, lead.

Meanwhile, it is tragic that the chancellor’s “budget for the next generation” did nothing to discourage the continued use of diesel: 10p a litre on the fuel would raise £1.7bn — enough to fill the hole left by the abandoned disability cuts.
