Bereaved families could face delays in arranging cremations reports BBC

Filters which will cut mercury emissions from tooth fillings by up to 99% are being installed in Gwent, Margam and Bangor crematoria, reports the BBC website.

Gwent said it will only have half of its usual 15 services a day until March as it strives to meet the UK government target of 50% mercury reduction.

Funeral directors have warned of delays of up to a month.But they say they are working with neighbouring crematoria to try to ensure families are not kept waiting too long during a "difficult and distressing time".

Strict rules for crematoria to limit mercury pollution with special equipment by 2012 were announced in 2005.Exposure to the metal is linked to damage to the brain, nervous system and fertility with crematoria responsible for around 16% of the UK's mercury pollution.

Swansea and Thornhill in Cardiff, have already fitted the filters.
