Beyond the Shaker: 12 Unexpected Household Toxins Stressing Your Kidneys

7. Plastics and BPA: Food Containers and Heat

Bisphenol A (BPA) and related compounds are used in some hard plastics and epoxy resins that line canned foods. Studies have found associations between higher BPA exposure and markers of kidney dysfunction in some populations, though research is ongoing. Heat and fatty foods increase the chance that chemicals can migrate from plastic into food, which raises exposure concerns when plastic containers are microwaved or used for hot foods. Reduce exposure with practical swaps: avoid microwaving food in plastic containers, choose glass or stainless-steel options for storage, and prefer canned goods labeled BPA-free when possible. For hydration, select bottles made from stainless steel or glass. Reducing routine dietary exposure cuts one common route for these chemicals and lightens the filtering work your kidneys must do.

8. Paints, Solvents and Degreasers: DIY Risks

Painting and home repair often use solvents, degreasers and oil-based paints. These products release VOCs and sometimes contain metals in older formulations. Prolonged or high-level exposures—especially without proper protection and ventilation—can affect multiple organ systems. For kidneys, solvents and certain metals have been implicated in workplace-related kidney injury in clinical reports, which is why careful handling at home matters. If you’re doing a DIY project, choose water-based, low-VOC paints and follow label directions for ventilation. Use gloves and masks rated for organic vapor protection when handling solvents, and store products in tightly sealed containers away from living spaces. For older homes, be cautious around chipped paint and consider professional testing if you suspect lead. These habits lower the risk of accidental heavy exposures and protect household members with increased vulnerability.
