Qantas chief executive Alan Joyce has been urged to review the airline's use of toxic firefighting foam following a leak at Brisbane Airport.
The head of Queensland's environment department, Jim Reeves, has written to Mr Joyce asking him to reconsider Qantas's use of perfluorooctanoic acid (PFOA) nationally.
The state's environment minister, Dr Steven Miles, has also called on the federal government to ban the use of substances that contain PFOA at Brisbane Airport and other Crown land sites across the state.
"As a result of the foam spill from a Qantas hangar at Brisbane Airport last week, Brisbane residents have been put at risk, which is a position that could have been prevented," he said in a statement on Thursday.
"What I want to know is why one of the country's largest and most reputable companies is still using firefighting foams containing PFOS and PFOA right here on our doorstep."
It comes after Dr Miles and the Palaszczuk government faced criticism for not notifying the public about the potentially dangerous leak sooner.
The spill of 22,000 litres of firefighting foam, caused by a sprinkler system fault within the Qantas hangar on April 10, was reported to the government last Tuesday but only made public on Good Friday.
"The state environment minister was alerted to this, it was his responsibility to let Queenslanders know that this had happened," opposition frontbencher Scott Emerson said on Tuesday.
But health authorities said members of the public shouldn't be alarmed, and the warning issued on Good Friday urging them to not eat seafood from the lower reaches of the Brisbane River and north to Shorncliffe was a precautionary measure.
"From the evidence ... one acute exposure is not going to do you any harm in the long term," Acting Chief Health Officer Dr Mark Elcock said in Brisbane on Thursday.
"It's more about your continual exposure to those chemicals."
While about three-quarters off the spill was contained, it's likely thousands of litres seeped into the wider environment and the stormwater system.
The leak has dealt another blow to the local prawn industry, which is already struggling with an outbreak of white spot disease.
Moreton Bay Seafood Association vice president Michael Wood said he lost a $10,000 order because of fears the waterway was contaminated.
"What's Qantas going to do? The industry's looking for compensation," he told AAP on Thursday.
For its part, Qantas said it was working as quickly as possible to determine the extent of any pollution.
PFOA, recently banned in Queensland, has been the subject of health scares following spills near air force bases in Oakey and Williamtown in NSW.
