Details of the study are published in the Scientific Reports journal. It writes the debris are likey to be ingested by humans if the fish is eaten in full. However, it is yet to be learned whether the chemicals in plastic are able to transfer into the meat.
The study was conducted by the researchers at University of California, Davis, and Hasanuddin University in Indonesia.
Lead author of the study, Chelsea Rochman, said there is no huge difference in the amount of such debris found in the fish of each location, but there is a difference in the type of debris. It differs from plastic to other debris.
For the study the researchers sampled 64 fish from Princeton and Half Moon Bay markets in California and Makassar market from Indonesia. The debris that were received from Indonesian fish were plastic and in the California fish most of the fish contained fibers.
In Indonesia large amounts of plastic are disposed onto the beaches and thereafter resulting entering the ocean. There are little ways of recycling the plastic products there. The problem there is further magnified due to poor quality of drinking water that forces people to consume bottled water. The plastic bottles are thrown too as a waste onto the beaches.
In California the reason is different. People wash their clothes in washing machines and water from it is piped to the wastewater treatment plants. Fibers remaining in sewage are thereafter ingested by fish.
