Five members of the Jones family from Llanfair Caereinion, mid Wales participated in the survey. They included grandmother, Morfydd Thomas, 88; mother, Enid Jones, 51 and husband Arwel Jones, 43 and their children Alwyn, 9 and Bethan Jones, 11 whose blood was analysed by the Scientific Analysis Laboratories Ltd in Manchester over the summer.

Alwyn, the youngest member of the family had the highest contamination in OCPs and Polychlorinated biphenyls (PCBs) which despite being banned from new electrical equipment in the UK before he was born had found their way into his blood. Bethan, had the lowest number of chemicals in her blood of the 33 people tested in the survey. She had a total of 17 chemicals; her mother had the lowest amount of chemicals of all adults tested; she had a total of 21.

Enid Jones, mother and member of Llanfair Caereinion's WI branch commented: "Despite our family following a relatively healthy lifestyle, I was shocked to discover that my children are being contaminated by certain man-made chemicals. It worries me that we don't know enough about what are in the products we use in our homes and their potential health effects. Surely as consumers we have a right to know and let our children grow up in a healthy environment?"

"These results are extremely worrying because of the unknown long-term health effects of the majority of industrial chemicals people are exposed to. The contamination of three generations of UK families including one in rural Wales with hazardous man-made chemicals clearly illustrates that industry and government have failed to control these chemicals," said Morgan Parry, Head of WWF Cymru.

"This is a wake up call to our governments in England and Wales and the European Union to stop repeating the mistakes of the past and ensure that these chemicals are banned and replaced with safer alternatives."

An EU proposed chemicals legislation, known as REACH, is currently with member states for consideration. It provides a once in a generation opportunity to secure adequate controls for these substances.

Contamination: the next generation yn datgelu canlyniadau saith teulu o Gymru, Lloegr a'r Alban a wirfoddolodd i gael profi eu gwaed am 104 o gemegau o waith dyn. O'r cemegau a ddadansoddwyd, canfuwyd 80 - darganfuwyd bod gan blant 75 o gemegau yn eu gwaed, darganfuwyd 75 yn y rhieni a 56 yn y neiniau.

Cymerodd pump aelod o'r teulu Jones o Lanfair Caereinion, canolbarth Cymru, ran yn yr arolwg. Y pump oedd y nain, Morfydd Thomas, 88; y fam, Enid Jones, 51 a'i gwr Arwel Jones, 43 a'u plant hwythau, Alwyn, 9 a Bethan Jones, 11, a dadansoddwyd eu gwaed gan Scientific Analysis Laboratories Ltd ym Manceinion dros yr haf.

Alwyn, aelod ifancaf y teulu, oedd wedi'i halogi fwyaf ag OCPs a biffenyl polyclorinedig (PCBs), a oedd wedi llwyddo mynd i'w waed er gwaethaf y ffaith bod eu defnyddio mewn offer trydanol newydd wedi'i wahardd yn y DU cyn iddo gael ei eni. Gan Bethan roedd y nifer leiaf o gemegau yn ei gwaed o'r 33 o bobl a brofwyd yn yr arolwg; roedd ganddi gyfanswm o 17 o gemegau. Gan ei mam roedd y nifer leiaf o gemegau o'r holl oedolion a brofwyd; roedd ganddi gyfanswm o 21.

Dywedodd Enid Jones, "Er gwaethaf y ffaith bod ni fel teulu'n byw'n gymharol iach, ces i fraw o ddarganfod bod fy mhlant yn cael eu halogi gan rai cemegau penodol o waith dyn. Mae'n peri pryder i mi na wyddom ddigon am yr hyn sydd yn y cynhyrchion a ddefnyddiwn yn ein cartrefi a'u heffeithiau posibl ar iechyd. Siawns nad oes gennym hawl fel defnyddwyr i wybod ac i fagu ein plant mewn amgylchedd iach?"

"Mae'r canlyniadau yn peri pryder mawr oherwydd effeithiau anhysbys tymor-hir ar iechyd y rhan fwyaf o'r cemegau diwydiannol mae pobl yn dod i gysylltiad â hwy. Mae'r ffaith bod tair cenhedlaeth o deuluoedd yn y DU, gan gynnwys un yng nghefn gwlad Cymru, wedi'u halogi â chemegau peryglus o waith dyn yn dangos yn glir bod y diwydiant a'r llywodraeth wedi methu â rheoli'r cemegau hyn," meddai Morgan Parry, Pennaeth WWF Cymru. "Dyma rybudd i lywordeath Cymru a Lloegr a'r Undeb Ewropeaidd i roi terfyn ar ailadrodd camgymeriadau'r gorffennol a sicrhau y caiff y cemegau hyn eu gwahardd ac y defnyddir cemegau eraill mwy diogel yn eu lle."

Mae deddf arfaethedig yr UE ar gemegau, a adwaenir fel REACH, ar hyn o bryd gyda'r aelod-wladwriaethau i gael ei hystyried. Mae'n rhoi cyfle unwaith mewn cenhedlaeth i sicrhau rheolaethau digonol ar y sylweddau hyn.
