You really need to be specific here. Everything is a chemical - the food we eat, the air we breathe, etc.

When I am looking at the chemicals and their effects, I like to consult the Merck Index.
If I am on the scene of a chemical release, I look at the NIOSH pocket guide and the Emergency Response Guide.
In summary the three best guides are:
1. Merck Chemical Index
2. NIOSH Pocket Guide (NPG)
3. Emergency Response Guide (ERG)
Happy reading!

the whole universe is within us and so whatever is without is also within.but just as the nature cannot withstand abuse similarly our body can accept chemicals in some limited quantities.some can be accepted in larger quantities without any harmful side effects and some only in microscopic quantities.when the limit is exceeded there are harmful effects.so i feel you should reframe your question as harmful effects of chemicals consumed indiscriminately and without discretion

all depend on the chemicals themselves and the levels of exposure. All chemicals have their own MSDS (Material Safety Data Sheet) you can find all the info in there including chemical, physical properties, effects, and first aid....

Ah, let me guess, chemictry is not your strong point.
It depends on what chemical. Everything we eat and breathe are chemicals.
For bad chemicals, they range from extremely toxic (like Arsenic) to safe (as in air). Water can be dangerous if you drink too much or if you drown.

Depends on the chemical and the exposure limit

All chemicals (organic and anorganic) are harmfull,
even water is harmfull (H2O).
"To much (exposure) is harmfull"
f.e. you are over exposed to much water ("drink to much")
you will drown.
Some "chemicals" can be very harmfull at very low concentrations as other you can be exposed at higher concentrations without harmfull effects.
Most safe is to prevent or reduce exposure to chemicals to a minimum.

Depends on the exposure level. Consult an industrial hygienist for answers.

Every substance in the world is hazardous at the right level.
