Yes, but it took many many years of campaigning by sufferers of organophosphate poisoning before anyone would take them seriously. Until then, the link was considered "tenuous".
But your reply does kind of prove my point. You've immediately homed in on one of the other potential causes of my condition, rather than considered lead as a potential cause, because it suits your agenda better to do that.
(Personally, I'm inclined to think that my condition is just bad luck. I don't blame anything).
Until we have information available from properly conducted studies, we'll never know whether the consumption of lead particles from game meat has any significant affect on human health.
But of course, this isn't all about humans. The fact that the ingestion of lead particles by birds, mistakenly for grit, is harmful and usually fatal, is indisputable, and for that reason alone we should be seeking out alternatives to lead and using them wherever and whenever it is practical to do so.
The real problem about all this - as I mentioned before - is that although the writing has been on the wall for lead for at least 40 years, everyone's still been caught on the back foot. Product developers and manufacturers have had decades to prepare for this, and most have just sat on their arses and done nothing. Now they're forced to do everything in a rush at the last minute, and as with all rushed projects, the result is not perhaps as good as it should be.
