All untreated wood cut offs are perfectly fine and don't give off anything
that isn't already in the air for one, but also what they do give off becomes
harmless within hours or up to a few days (see - "Wood Smoke and Your Health",
including its right side panels
https://www.epa.gov/burnwise/wood-smoke-and-your-health ).

However, in the case of Painted or Pressure Treated Wood (low-grade wood for
outdoor use) they should not be burned and only thrown in the trash for the
landfills (yes, your cheap wood or plastic composite deck is very far from
ecological), because they're full of petroleum distillates and pesticides.

All wood releases toxins and for that matter anything burned does too, yes
even your favorite cut of meat with grill marks or toasted bread is a now a
carcinogenic delight. Chimney liners, Stove pipes, Flues, Fireboxes and Ash
bins or pits should be scrubbed clean annually and handled as a Hazardous
Operation with all debris staying off you and going immediately to the
outdoors by a strong fan(s) or into a HEPA filtered vacuum.
