It’s not a wonder this forum has no posters - yer keep banning them…😄

Just to correct something - the research were first posted by call-sign onetrack

Putting some diversions up eh. Seems call-sign Ian is trying to run away from my prior questions with a subject that is new to him…😄 I were involved in this very same debate several years ago in pprune. Think it were call-sign Jabbawoky were pushing this new ‘fuel’ from gami…😉 Anyway, slight diversion to comprehending just what is in sea spray, or just a couple of em anyway… If yer believes Wikipedia: “…Viruses, bacteria, and plankton are ubiquitous in sea water, and this biodiversity is reflected in the composition of sea spray…” https://en.m.wikipedia.org/wiki/Sea_spray ….Yeah… don’t breath in sea spray - or if yer a fish don’t eat that stuff, because as it moves up the food chain the heavy metals, leads one of em, accumulates and then…🤨 Anyway, How goes the answers to my questions call sign Ian..🙂 .

Not at all. You were commenting about modifying lead exposure via removing a particular source. Therefor, by not going to the beach you are removing a source of lead exposure. You have compleat control over your exposure to ‘natural’ sources of lead - don’t go to the beach. Don’t eat food grown in leaded soils - which is most of Australia. Etc… So, he didn’t know where to buy the little can of wynnes additive..🤔 I don’t recall much of a fuss about the lead phase out - the cancer issue relating to the unleaded aromatics, well, thats another story. New cars were coming out with unleaded engines at the time and most of Australia’s car fleet turns over in about ten years… Aviation fleet turn over, well, thats another story… So you suggest we just roll over and die, eh..🤨 I should take the blame, eh..🤨 Why should I take on blame for something that contributes 1/16 of a poofteenth of sweet-feck-all of what is nowadays in reality a minor issue ? When we get to hear back from call-sign Ian trying to explain why the answers to my questions are a little ‘lacking’, then we can cover it some more. What all-ways makes me feel silly in hind-site if when I realise I’d lost my backbone over an issue. If you read the so-called research Ian presented you will note they left out certain demographics - Why? They try to blame lead for the violence of certain ‘demographics’ on lead exposure, when they should be looking at the destruction of the family values of those groups. 😑

Sounds like a conspiracy…..😉

The discussion is not about leaded petrol cars as such. As I have already covered, 99.999% of leaded petrol engines are now gone. And keep in mind that most of the leaded petrol cars were driven many times a week. Most piston engined aircraft in Oz don’t fly much at all - a lot of the charter ops are done with no-lead jet-A turbines or jets. “Source A, B…”… There is lead in sea spray. Are you suggesting that we ban going to the beach? Any adult who believes that nil lead is the only acceptable level would never take a child within miles of the sea side. Or creeks, or vegetables, or…… Where do you stop…

OKaaay…. Lets try again. Ian, reference the research paper under discussion: * The actual locations of the airports - How can I identify which airports are referenced ? * The size of the airports. * The actual locations of the various groups re distance from airport. Were they all located near one airport, or were they spread around. * The locations of toxic waste dumps. To add to my comments - Airports because of their size and late arrival to City/town development tend to end up in the old dump area or low lying swamp area etc, or have heavy industry located around them. * And yet. The other paper I referenced, whilst talking housing, does not mention airports. Ian, as you seem to have access to all this extra info, perhaps you can answer the actual points I raised..🙂

Seems you don’t know of the ‘crisis’ in medical research. Over 70% of medical research papers have been found to be crap. With those odds I probably didn’t even need to read the research paper to be confident of giving it the ‘crap’ rating…🤨 All and good, though does not answer the points I raised: * The actual locations of the airports - How can I identify which airports are referenced ? * The size of the airports. * The actual locations of the various groups re distance from airport. Were they all located near one airport, or were they spread around. * The locations of toxic waste dumps. To add to my comments - Airports because of their size and late arrival to City/town development tend to end up in the old dump area or low lying swamp area etc, or have heavy industry located around them. * And yet. The other paper I referenced, whilst talking housing, does not mention airports. Ian, as you seem to have access to all this extra info, perhaps you can answer the actual points I raised..🙂 And yet, as the Oz government data shows - there is natural lead everywhere in the environment - in the food we eat, in the creeks we swim in. The only way to get a nil exposure to environmental lead would to be locked up in a ‘safe room’. My argument has been from the get-go, that Aviation lead in Australia adds nothing of concern to the lead exposure that people are already getting naturally. 🙂

I don’t need to be wearing an Angel Flight cap when I help the old lady across the road. If yer keen why not just put the word out to a few country Dr’s that your aircraft is available as a free taxi service..🙂

OK, I’ve had a brief bit of a look-see and consideration...🤔 …..It’s Crap research. Apparently the airports they claim to base the research on are not actually listed. Whilst the big airports can be roughly defined on the research paper Wake county map, most cannot. The other county’s referenced in the paper have no map. Doing a bit of goggle maps correlating to the research paper map of Wake county some ‘airports’ appear to be little more then ‘one hanger’ bush strips. I note, of the 1267 children included in the research that they claim are within 500 metres of an airport they do not say how many at each airport. For all we know the 1267 kids are all at one location. The same for the 1000, 1500, and 2000+ distances - all the children could be at one location for all we know, right on top of the old toxic waste dump. Whilst housing gets a mention, there is no mention of toxic waste issues. A big issue in North Carolina apparently. Are any of these toxic waste sites located near the research paper reference airports? https://deq.nc.gov/about/divisions/waste-management/waste-management-rules-data/waste-management-gis-maps/federal-remediation-sites A read of a child lead research paper reference North Carolina makes no mention of airports. Seems there are other issues: “..Mothers of the 63.5% of children (402,002 of 633,159) linked to a blood lead test result were disproportionately young, Hispanic, Black, American Indian, or on Medicaid…” https://www.researchgate.net/publication/361030475_Patterns_of_Children's_Blood_Lead_Screening_and_Blood_Lead_Levels_in_North_Carolina_2011-2018-Who_Is_Tested_Who_Is_Missed 🤨

Well intentioned, though… I’m guessing when somebody wants to travel re medical issues they wants to get there by a set time. A pilot aborting due WX or unserviceability is fair enuf, though the ‘patient’ may be a little unwell and stressing and noting they could have driven there the day before. A few aborts and suddenly all pilots get a bad reputation. Imagine if the sick pax throws a fit or dies during the flight - Pilot liable ? As I say, well intentioned, though probably best kept clear of.

Furthering my research on the onetrack posting. I note reference to North Carolina in the research. For one thing NC has a lot of current and old copper mines which means…🤔 …including todays related industry’s they have an interest in monitoring lead: “…In May 2016, a North Carolina Childhood Lead Poisoning Prevention Program (NC CLPPP) epidemiologist noted clusters of elevated blood lead levels (BLL) among 16 children documented as take-home lead exposures in North Carolina’s lead surveillance system. Local lead investigators visited the homes of the children with confirmed BLLs greater than 5 micrograms per deciliter (µg/dL). They found lead dust on household members’ work boots, laundry areas, car upholstery, and children’s car seats. NC CLPPP partnered with North Carolina’s Occupational and Environmental Epidemiology Branch (OEEB), which houses the Adult Blood Lead Surveillance (ABLES) program. Through this partnership, NC CLPPP determined that the children’s exposures were linked to employees of two workplaces: a lead oxide manufacturer with 26 current employees and a battery manufacturer with over 400 employees. As the employees resided in multiple counties, the investigation crossed many jurisdictional boundaries…” https://www.cdc.gov/nceh/lead/programs/nc.htm 🤔… I don’t see any mention of aircraft ? .

Hmmm… please do point to the posts referring to all that...🤔 And, yet. There are all them natural sources referenced in the gov.au.edu web site I linked to…🤫 Perhaps Ian thinks they will be closing down the umpteen millions of geothermal vents around the world. No more drinking bore water or eating fish caught outer creeks and so on…🙂 As I’ve said before, like every thing in life, its the dose that matters. 🙂

Yer never know. I see he’s got the tail wheel on the wrong end of the aircraft…😃

Hmmm… Sometimes if yer want to get the ‘correct’ result yer just have to employ the ‘correct’ researchers. Lets have a brief look-see… Via the onetrack link: “…Residence in poor and minority neighborhoods was also associated with elevated lead levels. In contrast, recently constructed housing units were associated with decreased mean lead levels…” ..”minority neighbourhoods”. Hmmm… Perhaps we need to have a look-see at what else these researchers are up to…. “…Racial residential segregation has been associated with preterm birth. Few studies have examined mediating pathways, in part because, with binary outcomes, indirect effects estimated from multiplicative models generally lack causal interpretation. We develop a method to estimate additive-scale natural direct and indirect effects from logistic regression. We then evaluate whether segregation operates through poor-quality built environment to affect preterm…”. https://pubmed.ncbi.nlm.nih.gov/24681575/ Looking at the research I guess non-‘whites’ must live in old houses. Likely next to an old industrial estate, that’s usually located next to the ‘airport’. Nothing like kids playing in the dirt of an old industrial estate when they could be playing in the dirt of a new housing development out in the hills… I guess them bad bad whites flying around in their little airplanes are to blame…🤨 onetrack, I’m gunna have a further look-see at this research. I’d like to define just which ‘airports’ they used and have a look at the surrounding location. 🙂
