Mechanical pencil applied at an angle. When excess vertical pressure is applied on the lead, the lead is automatically retracted inwards. Higher-end mechanical pencils often feature a lead hardness grade indicator and sometimes feature a retractable lead guide pipe. This allows the lead guide pipe to retract back into the pencil body, which will keep it protected in storage and during transit and makes it 'pocket-safe'. In spite of the name, pencil leads do not contain the toxic chemical element lead, but are typically made with graphite and clay, or plastic polymers. Compared to standard pencils, mechanical pencils have a smaller range
Lead poisoning in raptors has consumed a lead jig or sinker if a fishing line breaks. They may also try to attack a fish being pulled in by someone fishing/angling. There is also tackle that becomes disposed of or left behind in the water or on the fishing grounds, which birds may then accidentally consume. What makes this issue even worse is that lead is not an element that is quickly eliminated and cannot be degraded, as it is a very stable element. This results in a continuous accumulation of the concentration of lead in the environment over time, as there is more going
