铅弹有多毒？

在这个温哥华牛人的一篇文章里，提到铅弹。铅弹真有这么毒吗？

在加拿大，打候鸟必须用钢珠弹头沙（steel）的子弹，严禁使用铅弹头沙（lead）的子弹，这么做主要是为了保护环境和减少候鸟的痛苦。毕竟很多情况里候鸟都只是受轻伤还可以飞走，钢珠伤一般可以自愈，但如果是铅弹，由于有毒性，就会慢慢的死去了。这里的常用弹药后面一排的就是猎候鸟用的钢珠弹。前面一排是从左到右就是猎山鸡，兔子和熊，鹿等大动物的铅弹。

抄一段关于铅中毒的教科书：
概述

"除非铅弹打到了或是进入了动物的消化系统或是呼吸系统”

铅单质会很容易变成让人中毒的铅化合物吗？我看不见得。有没有懂化学的同学来说一说？

NRA是坚决反对禁止铅弹的：http://www.spokesman.com/blogs/o ... ses-case-lead-ammo/

我5月16日收到的NRA ILA Alerts新闻上说即使反复用铅弹喂鸟也不能让鸟中毒：

The real truth is that lead ammunition is an unlikely cause of the alleged poisoning, because the metallic lead used in bullets and shot is relatively insoluble in the digestive tract of birds of prey and scavengers. Scientific studies have confirmed that it is very difficult to poison some birds with lead, even by repeatedly feeding them lead shot mixed with food over time.

On the other hand, lead compounds found in legacy paint, gasoline, insecticides and micro-trash are quite soluble in the digestive tract and are responsible for many of the highly publicized lead poisonings attributed to lead ammunition.  These lead compounds are common in the environment, and should be investigated first in cases of lead poisoning of wildlife.  The anti-lead ammunition researchers, however, typically ignore “alternative sources” of lead in the environmental, because the existence of such sources undermines their “get the lead out” campaign and the anti-hunting agenda.

鉴于大家对铅弹的毒性和NRA的观点有很大不同，并且最近铅弹被一些禁枪、控枪人当做了进攻拥枪、打猎者的新武器，我想把此贴移到“畅所欲言”版，以引起大家的注意。

铅中毒是慢性的，主要影响神经发育，也说有影响男性功能的。

铅在人体内半衰期是：血液30天，软组织1-1.5 ...

放射物质才有半衰期吧？铅是放射物吗？
