 Factors like smoking and air pollution are also linked to cardiovascular disease and higher plastic exposure, making it difficult to separate the independent effects of microplastics,  Routhenstein said.

 I would take inventory of your regular sources of microplastic exposure and see where you can reduce or swap them for better alternatives ,  Routhenstein said.  For example, replace plastic food storage containers with glass ones. 

She also urged taking extra precautions when preparing meals and drinking water .

 When microwaving or reheating food, use glass or ceramic containers instead of plastic,  she said.  It's also a good idea to limit plastic water bottles and single-use plastic containers, especially when they're exposed to heat.
