It is thought the lead pellets used in the shooting event could have an implication on the surrounding bird population in the area. If digested the pellets can kill.
The main criticism was launched by the National Trust for Scotland (NTS) highliting the recent plans to temporary lift the ban on lead shot for the Games. The ban was first put in place in 1990 to protect wildfowl and waterbirds from killing themselves by digesting the pellets.
It has now been confirmed the ban imposed by the government in 1990 to protect the wildfowl and water-birds has been temporary lifted for the event.
According to a government spokesperson the lifting of the ban will be "purely for the purpose of the competition", although this may also include several days before and after the event, and the amendment was passed after consultation with various authorities and environmental organisations.
"Strict measures are in place to ensure the clay target event at Barry Buddon will not put wildlife within the conservation area at risk," he told insidethegames.
"Measures include the use of a permeable membrane to recover the bulk of the lead shot, to prevent lead shot entering any wetland area."
Other environmental protection bodies have responded positively to the latest mitigation measures.
"All Commonwealth Games shotgun events are conducted according to International Shooting Sport Federation rules and regulations," a spokesperson told insidethegames.
"These rules state and allow for the use of lead shot only in the shotgun events as it is considered the best performance option for athletes.
"Glasgow 2014 has worked closely with Scottish Natural Heritage, Scottish Environment Protection Agency, Angus Council and the Ministry of Defence to develop a strategy for lead clearance.
"During the event, a mesh covering will be laid on the ground to gather shot fallout and debris from all the clay targets at the Barry Buddon Shooting Centre at Carnoustie."
