How do you know no other sources of lead ? There’s traces of lead in red wine and tea plus many other sources ? That study doesn’t seem exhaustive also says she was a smoker , probably one of @Heym SR20 s customers

Latest article on lead micro and nano particles in deer and grouse
- Thread starter Heym SR20
- Start date
I have to say that I think you're off target with this comment.
A person was ill from somehow swallowing a very large piece of lead shot (SSSG). That obviously happened, even though it's hard to understand how she could have been so silly. FWIW I once swallowed a live .22 round which was also pretty silly.

Think I have posted as others before, my parents used to eat so much shot game that there would be No.6 shot constantly in the bottom of the toilet bowl, didn’t harm them. We eat venison (I know lucky us!) at least once a week all year as does my young daughter and I never stop to think about the implications of the bullet that went through the deers head and the nano trace amounts of lead that may or may not be in our food, ridiculous. People should be more worried about all the chemicals that get into our food from cleaning products that are used in food prep areas, and the plastic that we are surrounded by that gets into everything.

Then ban the sale of lead shot carcasses into the food chain.
Dont ban the use of lead ammunition for those that are happy to use it and consume the meat themselves
The objection to the ban is really about the removal of freedom of choice

I just typed in the words “benefits of lead to human health” into Google
The result:
Lead provides no benefits to human health
and is a toxic heavy metal with no known safe level of exposure. Its presence in the body can cause serious, often irreversible, health problems across multiple organ systems.
One of the scientific papers linked to was this recent article in the Lancet.
The article identifies lead being linked to 5.5million premature deaths a year from coronary heart disease.
For all those who eat lead every day and drink contaminated water you might to have a read of before continue making claims that it dies no harm. It might not effect you, but it will by law of chance affect many others.

Assuming that the deer, or whatever, is shot only once and swiftly killed, it seems to me that widespread distribution of lead throughout the carcass due to the one hit is very unlikely...
However, a wounded animal carrying the fragmented bullet for a lengthy period might be a different matter.
From: Toxic Mechanisms of Five Heavy Metals: Mercury, Lead, Chromium, Cadmium, and Arsenic - PMC
Metals among the other environmental pollutants may also occur naturally and remain in the environment.
Hence, human exposure to metals is inevitable, and some studies have reported gender differences in the toxicity of metals
So humans and critters have likely been exposed to variable amounts of these heavy metals for millennia, and may even have achieved some natural tolerance due to evolution.

Not sure your synopsis of this article takes into account paragraphs such as
“On the other hand, low-dose exposure is a subtle and hidden threat, unless repeated regularly, which may then be diagnosed by its complications, e.g., neuropsychiatric disorders including fatigue, anxiety, and detrimental impacts on intelligence quotient (IQ) and intellectual function in children (Mazumdar et al., 2011). The fact that several metals have emerged as human carcinogens is another important aspect of the chronic exposure. While the exact mechanism is unclear, aberrant changes in genome and gene expression are suggested as an underlying process. Carcinogenic metals such as arsenic, cadmium, and chromium can disrupt DNA synthesis and repair (Clancy et al., 2012; Koedrith et al., 2013). The toxicity and carcinogenicity of heavy metals are dose dependent. High-dose exposure leads to sever responses in animal and human which causes more DNA damage and neuropsychiatric disorders (Gorini et al., 2014). The toxic mechanism of heavy metals functions in similar pathways usually via reactive oxygen species (ROS) generation, enzyme inactivation, and suppression of the antioxidant defense. However, some of them cause toxicities in a particular pattern and bind selectively to specific macromolecules. Different toxic mechanisms of heavy metals increase our knowledge on their harmful effects on the body organs, leading to better management of animal and human poisonings.”

Arsenic, cadmium, and chromium are toxic metals found in both tobacco and cigarette smoke.
My synopsis was an attempt to get interested parties to actually read the article........my own opinions agree with those mentioned in the article.
As an aside, I was process chemist in a lead refinery for a couple of years, so I'm well aware of the real-life ramifications of exposure to the metals mentioned.

Trouble with banning the sale of lead shot carcasses is two fold:
1) policing it. Judging by comments of many on SD, plenty would still shoot with lead and try and pass off carcasses as “lead free”. As these new studies with much greater resolutions using electron microscopy etc, conventional metal detection will not detect lead in such carcasses.
2) you will still leave lead fragments within the gralloch and disposed parts of the carcass and bullet fragments going into the soil. I suppose you could use a bullet that didn’t exit and the remove the complete carcass to a place where you would gralloch and then dispose of the waste as contaminated waste with all the additional costs and embuggerance that would entail.
Frankly why bother when monolithic copper bullets work well.

They don’t work as well.
They are not suitable for ALL firearms
It’s about freedom of choice (ie like being able to smoke or drink alcohol while being aware of the potential risk)

And thst is one of the very good reasons why smoking in public areas is now banned.
And like many from central Africa I will admit to being involved in the Tobacco industry during the early 1990’s. Tobacco was a valuable export crop for places like Zambia, we had 2,000 odd small holder farmers each growing 1/2 acre of Burley Tobacco. The fertilizer used and the money earned took these farmers out of pure substance agriculture. But I was also having to deal with the likes of Philip Morris etc and was offered silly money aged 22 to go and join them. Once I had had a look inside the industry I decided not to have any further involvement.
No amout of discussion on SD will make any difference to the HSE proposals before Parliament.
I don't want a ban but the use of lead in wildfowling was banned years ago. Spent lead shot does accumulate in raptors.
We need exceptions, air rifle pellets might be one as HSE recommend.
Muzzle loaders, yes that should be possible.

Of course. Why on earth not?

Lab grown supermarket meat vs lead shot meat.. I know which one I would rather eat. An incoming ban on lead for are “health” yet lab grown food is going to be made acceptable?? All you have to do is pick up the food you regularly buy in supermarkets and actually check the ingredients and will soon realise lead is probably one of the less toxic things in are food!

Yes, I have a muzzle loading rifle which I use to shoot deer occasionally. My freedom of choice to do so will be taken away with the forthcoming ban.
