**BabyLegs is an aquatic trawl (net system) for monitoring microplastic pollution and biological composition of surface water. ** This tool is comprised of a floatation device attached to a set of childrens tights - hence the name BabyLegs. To collect a sample, first you dip your BabyLegs into a waterway, then drag the device along the water’s surface. The fine-knit mesh of the tights traps microscopic bits of biological materials as well as nurdles and other plastics found within the water. These samples can be processed, identified, counted, and analyzed in order to examine what’s in your waterway. ## Microplastics Of the 5.25 trillion pieces of marine plastics in the world’s oceans, 92% are microplastics less that 5mm in size (Eirksen et al 2014), allowing them to be easily ingested by marine life as small as plankton (Cole et al 2013). Scientists are concerned that because plastics absorb up to a million times more chemicals than surrounding waters (Mato et al 2001), widespread ingestion means that toxicants that accumulate in animals can magnify up food webs, causing a potential threat to human health (Rochman et al 2013, Teuten et al 2009). This makes microplastics an environmental justice issue as people who eat marine mammals or who depend upon fish for sustenance are more likely to carry high toxic burdens. (text [from]( [![Microplastics-nickel-Hudson-BBL-2015-SM.jpg](/i/25546)](/i/25546) The image above shows some of the microplastics BabyLegs captured in the Hudson River, New York City. ## Activities [notes:grid:activity:babylegs] ## Questions Q: Can I change materials on the trawl, or change the design? A: Of course! The only thing you have to make sure of is that the mouth of the trawl is always half in the water and half out. It cannot dive or skip over the water. Also beware of any materials that might put more plastic into the ocean or into the sample (plastic 3D printing, fleece, and plastic thread are particularly bad for this). Also, the design outlined here has been tested in a variety of waters. New designs might not behave as well in choppy water, at higher speeds, or in wind. Q: What sort of data does a sample from BabyLegs yield? A: Things you can know from a sample: * The types of plastics (fragments, films, beads, threads, etc) that are in a body of water. * The relative frequency of each type of plastic compared to others (perhaps you have a lot of fishing gear, but not many microbeads compared to other places) * The relative hotspots for plastics if you do sample strategically in different areas. * Whether there are more or fewer plastics after rainfall events if you trawl before and immediately after rainfalls. This can include other temporal events that you think are adding plastics to your water (storms, tourist festivals, seasons). You will not know: * Where the plastics come from. They might be local, or they might have come from far away. * How long plastics have been in the water. Some things can get tossed around in strong waves and look beat up after short periods of time, while plastics that sink can look pristine after years. * About plastics that are smaller than 1mm. You might be able to see some, but research has shown that 1mm is the smallest cut off size that human eyes can reliably identify a plastic. Q: Has BabyLegs been validated? A. Yes and no. BabyLegs has been validated in laboratory settings to ensure that water flows freely through the device and does not "choke" on water. It is also how we determined that 5 knots is the maximum speed. However, BabyLegs has not been validated against another trawl to ensure she collects samples identical to scientific standards like the manta trawl. Stay tuned-- we should have it done by the end of fall 2018.

You can see that part of the trawl is underwater and some is above water, allowing the trawl to capture things floating on the surface. ...
