Childhood Asthma

In a large birth cohort, more frequent household cleaning product use in early infancy was associated with higher odds of wheeze and asthma by age 3.

37% higher odds of an asthma diagnosis at age 3 with more frequent cleaner use in infancy (adjusted OR 1.37).

Fertility Disruption

Endocrine-disrupting chemicals found in plastics and household products are associated with hormone interference. Hormonal disruption has been linked to reduced fertility in both men and women.

Animal research found that chronic exposure to a common disinfectant mixture (two widely used quats) significantly reduced reproductive performance, suggesting potential reproductive concern signals worth paying attention to as exposure increases. High‑exposure mice took 31 days to deliver a first litter vs 20 days in controls.

Cited source:

Chronic Inflammation

A human study measured common disinfectant chemicals used in cleaners (quats) directly in blood and found higher levels were associated with inflammatory and cellular-energy (mitochondrial) biomarkers.

The Study

Participants with detectable disinfectant residues in their blood showed over 10× higher levels of TNF-α, a key inflammation marker, compared to those without detectable levels.

Heart Attack & Stroke Risk

In a clinical observational study, patients whose artery plaque contained microplastics/nanoplastics had a much higher rate of major cardiovascular events during follow‑up.

4.53× higher risk of heart attack, stroke, or death when plastics were detected in plaque (hazard ratio 4.53)

Cited Source:

Decreased Testosterone

Certain plastic-related chemicals are classified as endocrine disruptors, substances that can interfere with natural hormone production. Research has linked higher exposure levels to lower testosterone in men.

Large U.S. biomonitoring studies have found that phthalates — chemicals commonly used to soften plastics — are associated with reduced serum testosterone levels. In nationally representative data (NHANES), multiple phthalate metabolites were significantly associated with lower testosterone, particularly among adult men.
