> The dump site is not regularly monitored by the British government, although the construction of a British Gas pipeline two decades ago resulted in thousands of second world war incendiary bombs being washed ashore, some of which exploded when they dried out. A four-year-old boy suffered burns in Campbeltown, Argyll and Bute, after picking up a device containing phosphorus.
The episode led to the last major survey of the maritime site, with dredging for the gas pipeline thought to have been the cause.
