Do heavy metals like lead and arsenic cause damage to human DNA

Yes

Explanation:

Some environmental factors- chemical, physical (UV), and biological (poisonous plants)- have the capability to damage DNA. This can lead to mutation, cell death, and several ailments.

Chemicals such as pesticides and heavy metals can be found in the environment (air, water) or in some consumer products.

The presence of Lead and a reactive oxygen species can result in DNA damage. Arsenic is classified as a carcinogen (cancer-causing substance).

More details are found in scientific articles online, but here's a helpful snippet- "heavy metal exposure can contribute to genetic damage by inducing double strand breaks (DSBs) as well as inhibiting critical proteins from different DNA repair pathways"
