Environmental Threats to Kidney Health: A Clinician's Guide to Modern Exposures.
AI summary Read the abstract
Your kidneys work hard to filter out toxins, but everyday chemicals from products, industry, and pollution—like lead, mercury, and "forever chemicals" (PFAS)—may be quietly damaging them more than doctors realize. This review pulls together existing research to show how these substances can harm kidney function, and argues that unexplained kidney disease may sometimes trace back to environmental exposures that go unrecognized in typical checkups. The takeaway: being aware of what you're exposed to at home, work, and in your environment—and asking your doctor about it—could help catch kidney problems earlier.
Individuals are increasingly exposed to a diverse array of chemicals through the environment, consumer products, and occupational settings. These exposures, often involving substances with unknown or emerging implications for human health, may pose significant kidney health risks because many are processed by the kidneys and excreted in the urine. Kidneys are particularly vulnerable to injury from inorganic chemicals such as lead, cadmium, and mercury. These originate from geogenic sources, but their exposures are multiplied by anthropogenic activities. Emerging data detail possible kidney risks from chemicals derived entirely from anthropogenic activities as well such as from per- and polyfluoroalkyl substances (PFAS), melamine, and agrochemicals. Chronic kidney disease resulting from these environmental exposures is likely underdiagnosed in clinical practice. This review describes the sources of exposure, systemic effects, and potential nephrotoxicity of implicated chemicals, aiming to increase the recognition of environmental exposures as contributors to unexplained new kidney disease. A thorough exposure history and specialized laboratory evaluation may be used for diagnosis in high-risk individuals. Increased clinical awareness and dedicated research efforts are essential to understand and mitigate environmental nephrotoxic exposures and protect kidney health.

Environmental toxicants and nephrotoxicity: Implications on mechanisms and therapeutic strategies
AI summary Read the abstract
This review examines how environmental toxicants, including microplastics, phthalates, and bisphenol A, can damage the kidneys. These substances can accumulate in kidney tissue after being swallowed, inhaled, or absorbed through the skin, triggering inflammation, oxidative stress, and cell death. The findings highlight that the kidneys, which filter about 200 liters of fluid daily, are particularly vulnerable to harm from the growing levels of plastic-related pollutants in our environment.
Environmental Chemistry of Emerging Contaminants and Their Anatomic Pathology Implications: From Molecular Perturbation to Tissue Lesions and Organ Dysfunction
AI summary Read the abstract
This review pulls together existing research to show how everyday contaminants like microplastics, "forever chemicals" (PFAS), and drug residues—now found in our air, water, food, and even body tissues—can actually damage cells and organs, leading to problems like inflammation, scarring, and in some cases, cancer-related changes. It matters because these substances are nearly impossible to avoid, and this paper argues we need better tools to connect environmental exposure directly to real, measurable harm in the body, not just theoretical risk.
Micro- and nanoplastics and the kidney: exposure pathways, toxicokinetics, and pathophysiological insights
AI summary Read the abstract
Tiny plastic particles from our air, water, and food—called micro- and nanoplastics—can enter our bodies and travel to the kidneys, where studies show they may cause cell damage, inflammation, and scarring over time. This review pulls together existing research on how these plastics get into our system and harm kidney tissue, suggesting that everyday plastic exposure could be an overlooked risk factor for kidney disease. More research is needed, but this is an early signal that reducing plastic exposure might matter for long-term kidney health.
Microplastiques : une menace silencieuse pour vos reins ?
AI summary Read the abstract
Researchers reviewed evidence on microplastic contamination and its potential effects on kidney health, noting that microplastics have been detected in kidneys and urine in humans. In vitro and animal studies suggest potential nephrotoxicity from microplastic exposure, and patients with kidney diseases may face increased risk due to higher exposure through medical procedures and reduced urinary elimination. The study calls for further research to clarify the relationship between microplastic exposure and kidney damage.
Systematic review of emerging environmental contaminants: sources, environmental fate, and impacts
AI summary Read the abstract
This review pulls together existing research on "emerging contaminants" — things like forever chemicals (PFAS), leftover medications, microplastics, and hormone-disrupting substances that build up in our water, soil, and food chains. The takeaway: these pollutants don't break down easily, accumulate in living things over time, and have been linked to hormone disruption, cell damage, and antibiotic resistance, yet current safety testing and regulations haven't caught up to the scale of the problem. For consumers, this underscores why reducing exposure to plastics and unnecessary chemical products matters, and why stronger monitoring and regulation are
