Indicate whether the statement is true or false

True. The silver found in used fixer of dental radiographic processors is in the form of a very stable silver thiosulphate complex. Thus bonded, there are virtually no free silver ions present in used fixer, prompting experts to conclude that used fixer poses very little threat to the environment if discharged into wastewater treatment facilities.
