"Effects from small plastic debris and sorbed chemicals may not be additive and future research is needed to identify the nature of the risks from this combination of s. It is likely that the risk to an will vary by type and size of plastic debris, which may affect its ability to concentrate chemicals from ambient water ... and in s … Risks may also vary over space and time due to the concentration of hazardous chemicals available for ... and the length of time the debris has interacted with ambient water and sunlight. of plastic increases surface area, and may enable greater accumulation of hazardous chemicals. Such complexity begs the initiation of research programs and risk assessments that are ecologically relevant ..."
