a pollutant in [air/water/soil]
ข้อผิดพลาดที่พบบ่อย:
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."
คำพ้องความหมาย

|
toxin (Stresses that the substance is poisonous or very harmful to health, not just dirtying the environment.)
คำตรงข้าม
purifier (Refers to something that removes harmful substances and makes air, water, or other materials cleaner, the opposite effect of a pollutant.)
