PARIS, France - Mosquito larvae have been observed ingesting microplastics that can be passed up the food chain, researchers said Wednesday, potentially uncovering a new way that the polluting particles could damage the environment.Microplastics -- tiny plastic shards broken down from man-made products such as synthetic clothing, car tyres and contact lenses -- litter much of the world&#x27;s oceans.<div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img src="https://sa.kapamilya.com/absnews/abscbnnews/media/2018/news/03/15/20150310-environment-plastics-aa.jpg"/></figure></div>Workers sort plastic bottles for sale at a plastic recycling factory in R10, Tondo, Manila.

They found that many of the particles were transferred into the mosquitoes&#x27; adult form, meaning whatever creatures then ate the flying insects in the wild would also ingest the plastic. &quot;The significance is that this is quite possibly widespread,&quot; Amanda Callaghan, biological scientist at Reading and the lead study author, told AFP. &quot;We were just looking at mosquitoes as an example but there are lots of insects that live in water and have the same life-cycle with larvae that eat things in water and then emerge as adults.&quot;The animals known to eat such insects include several species of birds, bats and spiders, all of which are hunted in turn by other animals. &quot;It&#x27;s basically another pathway for pollution that hadn&#x27;t been considered previously,&quot; Callaghan said.Although the team observed the mosquitoes in lab conditions, she said it was &quot;highly possible&quot; the process was already happening in the wild.Several countries including Britain have banned products containing microbeads, but Callaghan said the scale of the problem was still being discovered. &quot;It&#x27;s a major problem and those plastics already in the environment are going to be with us for a very, very long time,&quot; she said. <div>pg/mh/pvh</div><div>© Agence France-Presse</div>
