That was based on individual particulates, and the estimate of individual particulates. What the Committee on the Medical Effects of Air Pollutants analysis does is combine those particulates into what is a more realistic estimate of the kind of particulates that will exist in the air at any one time, which is where the figures for 1,000 to 1,400 come from.

Roedd hwnnw'n seiliedig ar ronynnau unigol, a'r amcangyfrif o ronynnau unigol. Yr hyn a wna dadansoddiad y Pwyllgor ar Effeithiau Meddygol Llygryddion Aer yw cyfuno'r gronynnau hynny yn amcangyfrif mwy realistig o'r math o ronynnau a fydd yn bodoli yn yr aer ar unrhyw un adeg, sy'n rhoi'r ffigurau rhwng 1,000 a 1,400.

It is the responsibility of the Valuation Office Agency, independently of the Welsh Government, to determine whether each property in Wales is liable for council tax or for non-domestic rates, and these decisions are made according to criteria set out in law.

Cyfrifoldeb Asiantaeth y Swyddfa Brisio, yn annibynnol ar Lywodraeth Cymru, yw penderfynu a ddylai pob eiddo dalu treth gyngor neu ardrethi annomestig, ac mae'r penderfyniadau hynny yn cael eu gwneud gan ddilyn meini prawf sydd wedi'u gosod yn y gyfraith.

Thank you for that answer, First Minister. The impact of the pandemic on learners in Wales has been unprecedented. Pupils have faced huge upheavals and many have seen their best laid plans and career paths disrupted through no fault of their own. In a recent study on the further education sector, the International Public Policy Observatory found that vocational and apprenticeship courses have been disproportionately hit by the pandemic. Across the UK, take-up of vocational courses, such as engineering and construction, have declined, and the number of young people starting new apprenticeships fell by 46 per cent in 2020 compared with 2019. I know that the First Minister agrees that no-one must be left behind in our recovery, and I'm pleased at the Welsh Government's ambition when it comes to apprenticeships. However, we must make sure that we protect the pupils who have been through so much over the last 18 months. What measures can the Welsh Government take to ensure that those whose educational plans have been disrupted are supported and given every opportunity to restart?

Diolch am yr ateb yna, Prif Weinidog. Mae effaith y pandemig ar ddysgwyr yng Nghymru wedi bod yn ddigynsail. Mae disgyblion wedi wynebu trafferthion enfawr ac mae llawer wedi gweld tarfu ar eu cynlluniau mwyaf trwyadl a'u llwybrau gyrfaol heb unrhyw fai arnyn nhw eu hunain. Mewn astudiaeth ddiweddar ar y sector addysg bellach, canfu'r Arsyllfa Polisi Cyhoeddus Rhyngwladol fod cyrsiau galwedigaethol a phrentisiaethau wedi eu taro yn anghymesur gan y pandemig. Ledled y DU, mae'r niferoedd sy'n dilyn cyrsiau galwedigaethol, fel peirianneg ac adeiladu, wedi gostwng, a gostyngodd nifer y bobl ifanc a ddechreuodd brentisiaethau newydd 46 y cant yn 2020 o'i gymharu â 2019. Rwy'n gwybod bod y Prif Weinidog yn cytuno na ddylai neb gael ei adael ar ôl yn ein hadferiad, ac rwy'n falch o uchelgais Llywodraeth Cymru o ran prentisiaethau. Fodd bynnag, mae'n rhaid i ni wneud yn siŵr ein bod ni'n amddiffyn y disgyblion sydd wedi bod trwy gymaint dros y 18 mis diwethaf. Pa gamau all Llywodraeth Cymru eu cymryd i sicrhau bod y rhai y tarfwyd ar eu cynlluniau addysgol yn cael eu cefnogi a'u bod nhw'n cael pob cyfle i ailgychwyn?

What's it called, sorry?

Beth oedd yr enw yna, sori?
