People are being reminded to take their sparklers home with them this bonfire night.
In years gone by, hundreds of sparklers have been collected from Weymouth Beach following the November 5 celebrations.
However these handheld fireworks can be harmful to both humans and wildlife if left discarded.
Dave Taylor, co-founder of the Weymouth and Portland Marine Litter Project said: "Fireworks season is upon us once again. I would issue a polite reminder to people who are celebrating Diwali, Halloween or Guy Fawkes - please do not leave sparklers or fireworks on the beach.
"Sparklers are very sharp and can injure dogs and children and fireworks contain plastic and harmful toxic chemicals.
"Please take your rubbish home and do not put spent fireworks in litter bins."

The plea comes after a bin along Weymouth Esplanade recently set alight. The incident was dealt with and the fire service did not attend.

Mr Taylor added: "Fireworks contain heavy metals which are toxic to wildlife many also contain plastic parts. It's actually a criminal offence to let off fireworks in a public place so ideally if people want to let off fireworks they should do so at home or attend an organised display."
The Weymouth and Portland Marine Litter Project is based in Wyke Regis and is a community interest company founded by local environmentalists Jane Fuhrmann and Mr Taylor.

Last year, the outer casings of 'rocket' fireworks ended up along the shoreline of Bowleaze Cove, and much of the Dorset Coast including at Chesil Cove and the Fleet.
- with environmentalists warning that these could potentially still have traces of 'toxic chemicals' inside.
Different metal compounds give fireworks different colours, for example, lithium salts produce pink, sodium salts make yellow, or orange, copper and barium salts generate green or blue, and calcium or strontium give red.
People should also be warned that there is a major safety risk involved when going along and picking up the debris as the firework may not have exploded.
Mr Taylor recommends 'that people go to an organised firework display,' rather than host their own.
