Yerman there is certainly getting some casting since Line of Duty... Hope his input to the oil industry is better than the shite they're producing about nuclear subs 😖

There you have it mucker.... "income" is irrelevant when viewed in isolation 😝

Having a pint with Tim & Nigel..... If you add strippers that'd pretty much be the ideal night out 😂

Did you ever pass that one? 😂😂😂😂

Whilst absolutely sharing your disdain for Westminster thieves, charlatans and wasters Al, it’s a bit harsh to vent at someone that is helping the masses to comply with the fraudulent dictats handed down from on high. I see how you might apportion some degree of compliance / blame to the rule takers - but not everyone is quite so ‘active’ a rebel as yourself. Whilst the ‘rules’ exist we need people that allow people to comply and JM provides excellent knowledge on the subject matter which is beneficial to many here. Hold your nerve mate - soon be 5 Nov 😂🧙🏻♂️🌟💣🧨

Air quality improvement from plants

That's a little harsh! Granted, I did start the thread and I do throw in the occasional hand grenade, but I'm not going to accept the label of "main culprit!" There are others far more qualified for that moniker than me Sir! -

There! My random, seat of the pants, man on the street, dullard predetermination is pretty much confirmed by Professor Paul Monks, University of Leicester and Chair of the AIR QUALITY EXPERT GROUP in his DEFRA (for DEFRA might as well read NFU) report "Effects of Vegetation on Urban Air Pollution." https://uk-air.defra.gov.uk/assets/documents/reports/cat09/1807251306_180509_Effects_of_vegetation_on_urban_air_pollution_v12_final.pdf "...In summarising the effects of urban vegetation on ambient concentrations of particulate matter and gaseous pollutants, there are potential benefits of vegetation in changing dispersion and deposition processes and also potential problems. For dispersion, locally (tens to hundreds of square metres) the planting of trees may enhance or reduce dispersion; this redistributes pollution but does not remove it. ...the magnitude of the reduction in concentration by realistic planting schemes, using trees, is small and in the range 2% to 10% for primary PM10 and ambitious plantings. For practical planting schemes and PM from all sources, the scale of reductions is expected to be no more than a few percent. For NO2, vegetation is not a very efficient sink, and as the deposition occurs in daytime, and primarily in the warmer months, there is little benefit for air quality for most of the time that NO2 is a problem. ...the specific contribution from city centre vegetation is too small to be isolated in modelling studies. Increasing tree cover in cities has the potential to increase BVOC emissions, with impacts felt through small increases in ozone and possibly aerosols downwind. ...Of potential relevance to UK planting, oak, aspen and willow species should be avoided since these are estimated to being highest BVOC emitting species. -

That's an interesting progression - I likey 😃 Likely, I'd suggest, that the macro impact is fairly undeniable - like Asian and Amazonian forest cover, continental and even national tree cover. I wouldn't spend any time trying to challenge the positive effect of canopy cover at those sorts of levels. But does it actually scale down to individual street tree? I'd probably be content to loosely map across the apparent conclusions from house plants impact upon air quality (improving the physical / mental health, providing a pleasant environment etc etc) to the street tree level, although I'd probably need more convincing that each single tree makes a significant difference to air quality. That said, I certainly endorse the approach that each tree matters since every woodland / forest must have started from a single tree and anything that raises public awareness and engagement at the lower levels is likely to be a good starting point for understanding and appreciating the larger scale. Street trees benefit to air quality - like house plants, you'd need 1000s possibly 10s of 1000s / km2 to come anywhere near. Making a nice street scene and regulating temperature - absolutely no argument with that! (I had to change "Amazon" to "Amazonian" because the global lizard overlords auto inserted a hyper link to a proprietary online shopping platform - sneaky bar stewards) (There! It's happened again! Damn your lizard eyes!) -

Brilliant - you call it cross ‘contamination’ I call it cross ‘pollination.’ 😂 -

I’m gonna call BS on the conclusions / summary now. “...Their increased use in both ‘‘green’’ and traditional buildings could have a tremen- dous positive impact on the ornamental industry by increasing customer demand and volume of sales...” It shouldhave said - the preceding article is sponsored by houseplantsdirectdotcom 😂 -

What Indoor Plants Clean the Air Best? None of Them. - The Atlantic WWW.THEATLANTIC.COM The science is clear: Indoor vegetation doesn’t significantly remove pollutants from the air. Apparently - "....For several years, research really did suggest that houseplants might cleanse the air of certain pollutants. But now most scientists say that’s not right...." But, but, but, but..... If we accept that scientists might 'change their mind' on something so seemingly innocuous as the relative benefits (or otherwise) of a house plant, that would mean the 495 pages of interminable disagreement on the C19 thread might actually not have been a complete busted flush? I genuinely 'wanted' to believe houseplants cleaned the air we breath.... Turns out, it was all just a misrepresentation of the existing data to exploit consumer frailty and the willingness of the masses to just 'believe' - which, in and of itself, must either be an affront to science or an indicator that science is being corrupted to influence human behaviour. -

I see where you were going with that now..... 🤣 -

Which houseplants should you buy to purify air? None of them. WWW.NATIONALGEOGRAPHIC.COM Bringing plants indoors can provide a number of benefits, but cleaner air isn't one of them, say experts. Who to believe.... The tinter web (and the BBC) is telling me different answers to the same question 🤯 Do houseplants really improve air quality? | Gardening advice | The Guardian WWW.THEGUARDIAN.COM Received wisdom is all very well, but sometimes the science proves otherwise, says James Wong "...If you want fresh air, open a window. If you want to witness the joy of nature and feel a daily sense of wonder, get some houseplants..." I can relate that...... Not sure the same logic applies inside the M25 though? I'll just get some more plants because I like them -

Not a bad mantra for life really.... (unless the subject is C19 (and houseplants - apparently) 😂) -

kevinjohnsonmbe replied to kevinjohnsonmbe's topic in Tree health care
Any particular types of plants? Presumably some are better at absorbing pollutants whilst others are better at producing oxygen etc etc. I’ll have a bit of time tomorrow looking into it. -

Just a general interest in the composition of what we are sucking in and any ways it might be improved. Don't go getting all technical (well do) I'm not a scientist! 😂 -

I was only ½ watching / listening while cooking the roast. I did look at ‘air quality’ plants when the conservatory was done. Going to refresh my memory and perhaps source some more. It’s a day room so not overly concerned about overnight. Going to look up those air quality monitors too. Just out of interest. -

There’s NASA research to support the theory K. Prob best not get too close to school - you know, restraining order an all that.... -
Great feature on RHS Chelsea Flower show prog on BBC about air quality improvements in school with plants. Pretty basic stuff really but always good to have a reminder at times. What with air quality being such an on topic subject at the moment might have buy a few more...

Awesome!

Fine looking dog 👍🏻 We’re down to 1 at the moment 😫

Modern Vans, 4/7.5t more like driving a car these days - mind you, if the Fiat 500 driver I met in the lane last night and who couldn’t reverse for toffee is anything to go by..... 🙀

Perhaps it’s time for a ‘refresh?’ Vehicle tech has advanced massively over the years, has the test kept pace with vehicle capability changes? Does it need to? Don’t know, just wondering.
