Lead Fishing Weights

Here is what the environment agency says about lead weights:

No fishing weights made of lead may be used except those of 0.06 grams or less and those of more than 28.35 grams.

In angling terms this means that lead shot from size 14 to size 8 and lead weights of over 1 ounce can be used in fishing.

While lead dust shot (size 8 and smaller) are legal, they are toxic to birds if ingested. Use spillproof containers for lead dust shot and always dispose of used lead safely at home.
