Assessment of GAPI for the proposed method.

S.No.	Category	Proposed method	Colour
I	Sample preparation
1	Collection	UV	Green
2	Preservation	None	Green
3	Transport	None	Green
4	Storage	None	Green
5	Type of method: direct or indirect	Simple procedures	Yellow
6	Scale of extraction	Simple extraction using water	Green
7	Solvents/reagents used	Green solvents	Yellow
8	Additional treatments	None	Green
9	Reagent and solvents amount	<10 mL	Green
10	Health hazard	HCl and NaOH	Yellow
11	Safety hazard	HCl and NaOH were used very less so that flammability will be negligible.	Green
II	Instrumentation
12	Energy	UV consumes ≤0.1 kWh per sample	Green
13	Occupational hazard (OH)	None	Green
14	Waste	Waste generated by the proposed method were 1–10 mL.	Yellow
15	Waste treatment	Low degradation	Yellow
