Final answer:
Clair Patterson discovered that our planet was being poisoned due to industrial pollutants and chemicals such as lead in gasoline.
Step-by-step explanation:
Because of his experiment, Clair Patterson also discovered that our planet was being poisoned due to the widespread use of industrial chemicals, such as lead in gasoline, as well as other pollutants like chlorofluorocarbons (CFCs) and persistent organic pollutants (POPs). These substances accumulated in the environment and in the bodies of living organisms, leading to harmful effects on health and ecosystems. Patterson's work brought attention to the dangers of environmental contamination and led to policies aimed at reducing the presence of toxic substances in our surroundings.
