answer: Lead poisoning
Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion.
The United States banned the manufacture of lead-based house paint in 1978 due to health concerns. Lead paint was only banned in the European Union in 2003 by the Restriction of Hazardous Substances Directive (RoHS) ; but many countries had already banned it on their own (France, 1949).The main health concern is for expecting mothers, babies and infants that can develop lead poisoning (saturnism) if they ingest too much lead.
The California condor is a collateral victim of lead use. When a gun fires lead ammunition and it hits an animal, the soft metal breaks into many small fragments that spread beyond the wound channel. When scavengers such as condors feed on these remains, they inadvertently ingest the lead fragments. If scavengers eat enough lead, it poisons them and they can die
Evidence of elevated lead exposure in California condors began to emerge in the mid-1970s, and lead poisoning may have been a factor for their near-extinction in the 1980s.
Louis Tanquerel des Planches, a French physician, is known for his research of lead poisoning and he is credited with conducting one of the first comprehensive studies of occupational illness.
