Who discovered the Antarctic ozone hole in 1985?

Explanations: answer key for all 10 questions

Q1: What does the ozone layer protect us from?
Answer: Ultraviolet radiation
It absorbs much of the Sun's harmful UV light.
Q2: Which chemicals damaged the ozone layer?
Answer: CFCs
They were used in fridges and sprays.
Q3: Which 1987 treaty phased out ozone-damaging chemicals?
Answer: Montreal Protocol
It is considered a major success.
Q4: Which gas is the main human-caused greenhouse gas?
Answer: Carbon dioxide
Methane is also powerful.
Q5: Which gases cause acid rain?
Answer: Sulfur dioxide and nitrogen oxides
They form acids in clouds.
Q6: What is a main ingredient of summer smog?
Answer: Ground-level ozone
Sunlight reacts with car pollutants.
Q7: What does extra CO2 do to the oceans?
Answer: Makes them more acidic
This harms corals and shellfish.
Q8: Why was lead removed from gasoline?
Answer: It was toxic to people
Leaded petrol was phased out worldwide by 2021.
Q9: Fertilizer runoff causing algae blooms is called what?
Answer: Eutrophication
It can create dead zones.
Q10: Who discovered the Antarctic ozone hole in 1985?
Answer: British Antarctic Survey scientists
Farman, Gardiner and Shanklin reported it.

Environmental Chemistry Quiz – Chemistry and the Planet

Environmental chemistry studies how chemicals move through air, water and soil and how they affect living things. Human activities have changed the chemistry of our planet in many ways, from the air we breathe to the oceans.

Some problems have been tackled successfully. The Montreal Protocol phased out CFCs, and the ozone layer is slowly recovering. Removing lead from gasoline and sulfur from power plant emissions reduced poisoning and acid rain.

Other challenges remain, including greenhouse gases warming the climate, ocean acidification, plastic and chemical pollution. Chemists help by monitoring pollution, designing cleaner processes and developing greener materials.
