As you said, there are trace amounts of lead and even arsenic in agricultural products for all kinds of reasons, some plants LOVE to fix heavy metals. > If you look at how much lead and other toxins you're exposed to through a variety of sources it will add up over time There's simply no evidence to support the broad claim that different toxic substances below their safe thresholds cumulatively are unsafe. > Simply because it doesn't add up to the thresholds for lead poisoning doesn't mean it lacks any negative consequences Sure, but you can't in practice prevent ever conceivable negative outcome. You have to think about tradeoffs.
