Weinidog, fe sonioch chi am lefel y nitrogen deuocsid, ac fe fyddwch yn ymwybodol o astudiaeth yr Athro Paul Lewis ym Mhrifysgol Abertawe mewn perthynas â hyn - dengys ffigurau fod y lefelau'n uwch na'r terfynau diogel mewn 81 o 916 man, gan gynnwys wyth lle yn Sir Gaerfyrddin, gyda heol Felinfoel yn Llanelli yn un enghraifft. Pa werthusiad rydych chi a'ch swyddogion yn ei wneud o gamau fel y terfynau 50 mya ar rai cefnffyrdd a rhannau o'r M4 ers eu cyflwyno? A ydym yn gallu gweld pa wahaniaeth y mae'r rheini'n ei wneud eto? Pa drafodaethau diweddar a gawsoch gydag awdurdodau lleol i wella'r gwaith o fonitro lefelau llygredd, gan y byddwch yn ymwybodol fod rhai cymunedau'n poeni bod ganddynt lefelau a all fod yn beryglus, ond nad oes monitro'n digwydd yno. Ac a ydych wedi rhoi mwy o ystyriaeth i'r angen am Ddeddf aer glân newydd i Gymru?

Minister, you mentioned the level of nitrogen dioxide, and you'll be aware of the study being undertaken by Professor Paul Lewis at Swansea University in this regard - figures showing 81 out of 916 places exceeding safe limits, including eight in Carmarthenshire, and one example being the Felinfoel road in Llanelli. What evaluation are you and your officials making of moves like the 50 mph limits on certain trunk roads and parts of the M4 since they were introduced? Are we yet able to see what difference those are making? What recent discussions have you had with local authorities to improve the monitoring of pollution levels, because you will be aware that there are communities that are concerned that they've got levels that they feel may be dangerous but the monitoring just isn't there. And have you given any further consideration to the need for a new clean air Act for Wales?

Weinidog, mae'r cynnydd yn y galw i'w groesawu'n fawr iawn, fel y mae ymestyn y meini prawf cymhwysedd, ond yn anffodus, mae gennyf bobl yn fy etholaeth sydd wedi cael clywed na allant drefnu apwyntiad i gael pigiad rhag y ffliw yn eu meddygfeydd am fis arall, sy'n amlwg yn gwbl annerbyniol, yn enwedig i'r rheini yn y categorïau agored i niwed rydych eisoes wedi cyfeirio atynt. Ac wrth gwrs, nid dim ond y brechlyn ffliw y mae pobl am ei gael; ceir brechlyn niwmococol hefyd i ddiogelu pobl rhag niwmonia, ac rwy'n ymwybodol fod yna brinder o'r brechlyn hwnnw ledled Cymru a rhannau eraill o'r DU ar hyn o bryd. Pa gamau rydych chi'n eu cymryd i sicrhau bod digon o gapasiti yn y system i allu diwallu'r galw am frechiad i bawb sydd ei angen?

The increase in demand, Minister, is very, very welcome, as is the extension of the eligibility criteria, but, unfortunately, I've got people in my own constituency who have been told they cannot schedule a flu jab appointment with their GPs until a month hence, which is clearly completely unacceptable, particularly for those in those vulnerable categories that you've already referred to. And, of course, it's not just the flu vaccine that some people need to access; there's also the pneumococcal vaccine to protect people against pneumonia, and I'm aware that there are shortages of that vaccine across Wales and, indeed, other parts of the UK at present. What action are you taking to make sure that there is sufficient capacity within the system to be able to meet the request for vaccination from all those who need it?
