Interpretation:
A short report describing the Montreal Protocol and more recent environmental measures to reduce CFCs needs to be written.
Concept introduction:
A group of unperfumed manufactured chemicals is Chlorofluorocarbons (or CFCs). Chlorofluorocarbons are anthropogenic compounds. CFCs were developed (or formed) as a safe choice to ammonia, a popular refrigerant. CFCs are anthropogenic compounds, used as an alternative of refrigerants.
Answer to Problem 53A
The Montreal Protocol was signed to break the production and also, import of ozone-depleting substances as well as decrease their concentration in the atmosphere to guard the ozone layer of earth.
Explanation of Solution
Chemicals on a list of controlled substances following the Montreal Protocol comprise, halons, CFCs, methyl bromide, and HCFCs, they are communally referred to as ozone-depleting substances. Most of them are very potent greenhouse gases.
The Montreal Protocol is a globally treat to guard the stratospheric ozone layer (or ozone shield) by phasing out the production and also, consumption of ODS (or ozone-depleting substances). In the year 1987, leaders from different nations met in Montreal (a city in Canada) and signed the Montreal Protocol.
Since the year 2013, annual emissions of banned CFC (chlorofluorocarbon) have risen by around 7, 000 tons from eastern China. According to the latest research printed in Nature today by an international team of scientists from different countries.
The Montreal Protocol is a treaty, signed to protect the earth from CFCs.
