Common Pitfalls
A common confusion arises between “harmful” and “noxious.” While both suggest damage, “noxious” specifically refers to substances causing harm through chemical means (e.g., gases, toxins). Using “noxious” to describe non-chemical harm can be inaccurate.
Similarly, “adverse” is often used interchangeably with “detrimental,” but it’s more appropriate for conditions or factors rather than actions. For instance, “adverse reactions” are outcomes, whereas “detrimental habits” refer to behaviors.
