Carcinogenic formaldehyde in U.S. residential buildings: Mass inventories, human health impacts, and associated healthcare costs

Highlights

  • Open Standards of the Health Product Declaration (HPD) enable mass estimates.

  • 29,800 ± 5760 metric tons of formaldehyde were used to construct US homes nationwide.

  • In 2022, a new US residence contained an estimated 207 ± 40 g of formaldehyde.

  • Up to 4 years is required to safely vent formaldehyde from residential houses.

  • Avoidance of formaldehyde in US housing could avoid 645 ± 33 cancer cases per year.

High resolution data visualization and machine learning prediction of free chlorine residual in a green building water system

Highlights

  • Real-time water quality data visualizations could inform the development of water quality management approaches.

  • Random forest outperformed time series LSTM machine learning (ML) models to predict free chlorine residual as an outcome variable.

  • Models accurately predicted free chlorine residual lapses 5 min in advance and up to 24 h in advance.

  • ML predictions outperform conventional statistical approaches to inform building water management plans.

Protecting Consumers And The Chemical Industry: A Policy Framework For Limiting The Production Of Halogenated Hydrocarbons

Highlights

  • Overuse of organohalides: Toxic halogenated hydrocarbons (organohalides) are causing significant healthcare costs and environmental issues.

  • Economic burden: The annual healthcare costs associated with organohalides are estimated to be US$340 billion in the U.S. and €150 billion in the European Union.

  • Industry impact: Chemical giants have faced billion-dollar lawsuits and bankruptcies due to the harmful effects of organohalides.

  • Proposed solution: HERO: The proposed policy is a novel economic incentive designed to reduce the use of organohalides.

  • How this policy works: By placing a health premium on new carbon-halogen bonds, this policy encourages the development and use of safer, alternative chemistries.

  • Benefits of adopting this policy: It is a proactive, non-limiting approach that promotes green chemistry, avoids new regulations, and supports consumer needs.

  • Positive outcomes: This framework promises to reduce the use of toxic chemicals, minimize healthcare costs, and align with sustainable development goals.

A wastewater-based epidemiology and material investigation framework to track phthalate exposure from commonly used building materials

Highlights:

  • Phthalates, commonly used in building materials, pose significant health risks including reproductive abnormalities and potential carcinogenicity.

  • An analysis of the Health Product Declaration (HPDC) repository revealed that a substantial number of building products contain phthalates, particularly doors and windows.

  • Dust inhalation from phthalate-containing building materials poses a quantifiable risk to human health.

  • Wastewater-based epidemiology (WBE) is a viable and cost-effective method for monitoring phthalate exposure.

  • Safer alternatives to phthalates, such as cardanol and epoxidized soybean oil, are available and should be adopted to mitigate health risks.

Identifying optimal sampling points in wastewater networks for SARS-CoV-2 to inform efficient monitoring efforts and public health decision-making

Highlights:

  • Effective wastewater-based surveillance: This study demonstrates the importance of wastewater-based epidemiology (WBE) for monitoring SARS-CoV-2 in communities.

  • Optimal sampling point selection: By using the Storm Water Management Model (SWMM), the study identified the most effective locations for sampling wastewater to detect the virus.

  • Targeted sampling for improved results: Targeted sampling based on population density and key infrastructure points was found to be more efficient than random sampling.

  • Integration of relevant data: The study successfully integrated data on wastewater flow rates, population density, and land use patterns to inform sampling point selection.

  • Enhanced public health decision-making: The optimized sampling strategy can provide valuable data to inform public health interventions and decision-making regarding the COVID-19 pandemic.

  • Cost-effective and non-invasive monitoring: Wastewater-based surveillance offers a cost-effective and non-invasive alternative to traditional testing methods.
