Plastic wood made from wood chips is becoming more toxic as a result of industrial pollution and food processing.
Plastic wood chips have been found in the wastewater of factories, restaurants and the recycling industry, posing a threat to aquatic life, according to a study published in Environmental Science and Technology.
The study, conducted by researchers from the US and China, found plastic wood chips were being released into waterways as a by-product of the plastic processing industry.
The findings, based on a global survey, were published in the journal Science.
The researchers found plastic chips were leaking into waterways where aquatic life could feed on plankton and algae, according the study.
In some cases, the plastic chips had been washed ashore by a beach or in storm drains.
They also found that a similar number of plastic wood products were found in food packaging in China, which could lead to contamination of local waterways.
“It is possible that these contaminants are being released from the waste stream directly into the food supply, where they could enter the food chain,” said study lead author David Fischbach.
“We need to take this issue very seriously.”
The researchers used data collected in China and the US to monitor the levels of plastic debris in rivers, lakes and lakes and the water quality of rivers and lakes.
They found the amount of plastic that was floating in rivers increased by 40 percent and the amount that was deposited in the oceans increased by about 30 percent in the past decade.
Plastic debris was also found in waterways where fish, wildlife and people were eating fish, according a report published in Science.

The plastics found in these lakes, rivers and waterways were made from different types of plastic.
For example, one type was made from the same type of plastic used in toilet paper.
The other type of plastics was found to be more toxic.
Plastic pollution has been linked to a variety of health problems, including cancer and cardiovascular disease.
In 2015, scientists from the World Health Organisation (WHO) warned that the global plastic pollution crisis was “at its peak”.
The report said plastic pollution had become “increasingly serious” because of the amount and types of products made from it.
Plastic is often made from polypropylene (PP), which is a synthetic plastic used to manufacture everything from clothes to carpets to glass and other products.
Plastic was used to create the plastic used as packaging in the first decades of the 21st century, with the introduction of the first commercial plastics, such as polyethylene, polystyrene and polyvinyl chloride (PVC).
But over the past two decades, plastic manufacturing has largely shifted to the plastics made from waste products and plastic waste.
The World Health Organization (WHO), which commissioned the study, said plastic waste from waste streams, like the waste water of factories and restaurants, was a major source of plastic pollution in the world’s oceans and in freshwater ecosystems.
The WHO said there were no safe limits on the amount plastic could be released into the environment, but that “it is a global problem and a challenge”.
“There is no safe limit on the quantities of plastic being produced, transported or dumped into the ocean and freshwater ecosystems,” the WHO said.
Plastic waste from the plastic industry has been detected in the Gulf of Mexico and at the mouth of the Mississippi River, and in lakes and rivers throughout the US.
The agency said in a statement that the amount released into these environments was “significant”, and the “unusual concentrations” were a concern for human health.

The plastics released into rivers and oceans had also increased.
The report found that plastic from plastic debris was a “key source” of plastic waste in rivers and freshwater.
The scientists from Beijing and Washington also found a correlation between the amount a person consumed of fish and their risk of developing cancer, and that people who were overweight or obese were more likely to develop cancer.
The paper said that it was not clear how much plastic was being released by waste streams.
“The amount of waste that we have identified, and the types of waste, are not well understood and could potentially be increasing,” said Fischfeld.
“More work is needed to identify the sources of these plastic particles, their impact on aquatic life and to determine the health impacts of these particles.”
Plastic waste is also used to form plastic sheeting.
The new study found that the types and sizes of plastic material used in building materials, such flimsy plastic bags and plastic containers, had increased over the years, but it was unknown how much.
The plastic bags were also found to have higher levels of the chemical benzene.
