Greșeală frecventă:
Learners often confuse "pollutant" (a countable noun for the substance) with "pollution" (an uncountable noun for the general problem). For example, "There are many pollution in the river" is incorrect; it should be "There is a lot of pollution in the river" or "There are many pollutants in the river."
Sinonime
contaminant (More general; any unwanted substance that makes something impure, not only in environmental contexts.)
|
toxin (Stresses that the substance is poisonous or very harmful to health, not just dirtying the environment.)
Antonime
purifier (Refers to something that removes harmful substances and makes air, water, or other materials cleaner, the opposite effect of a pollutant.)
