Environmental campaigners are calling on their council to ban noisy petrol-powered leaf blowers.
Harrow Green Party representatives claim the machines are a “serious health, safety and environmental hazard” as they cause significant air and noise pollution.
They have urged Harrow Council to ban petrol leaf blowers used by its staff, contractors and affiliates in public spaces.
The group say leaf blowers can “permanently damage” the hearing of those using them and those living nearby.
It added they can release “harmful emissions”, and suggested it was an “inefficient” way of clearing leaves as they “often blow back” soon after.
As well as carbon emissions, the Green Party members claim leaf blowers can blast other damaging elements into the air, including mould, animal poo, pesticides and even pieces of metal.
They claim it can affect those with asthma, hayfever and other respiratory conditions and is particularly harmful to vulnerable people such as children and the elderly.
They are also concerned about the impact on local wildlife and their habitats.
They argued the machines can kill beneficial insects such as ladybirds and butterflies, while they can scare off animals such as hedgehogs and rabbits, which might be foraging or hibernating under leaves.
The campaigners pointed out there have been examples of other authorities taking action against petrol leaf blowers.
They explained they have been banned in New York’s Central Park, while Camden Council has previously restricted the use of leaf blowers during the spring and summer months.
Harrow Council has been contacted for comment.
