Importance: Beginning in the 1940s, radioactive waste from the effort to develop an atomic bomb was stored in the open near the St Louis, Missouri, airport, and over several decades contaminated nearby Coldwater Creek.
Objective: To evaluate whether living near Coldwater Creek in childhood was associated with self-reported cancer incidence in the St Louis Baby Tooth-Later Life Health Study (SLBT).
Design, Setting, And Participants: The SLBT cohort study was centered in St Louis and included individuals who donated their baby teeth from 1958 to 1970 to assess exposure to atmospheric nuclear weapons testing.
Article Synopsis
- Research indicates that exposure to a mixture of toxic and essential metals in men from the US Gulf states may affect cognitive functions like attention and memory.
- The study involved measuring toenail concentrations of eight metals in 413 non-smoking men and assessing their neurobehavioral performance.
- Significant findings showed that higher levels of chromium and manganese correlated with reduced attention and memory scores, with more pronounced deficits in Black participants compared to White participants.
Article Synopsis
- The study examines the demographics, usage patterns, and health outcomes of e-cigarette users, focusing on two types of devices: large modifiable (MOD) and small affordable (POD).
- It recruited 91 participants, categorizing them into MOD users, POD users, dual users (both cigarettes and e-cigarettes), and non-users, collecting data via questionnaires and analyzing it through various statistical methods.
- Results revealed that POD users tend to be younger and report more coughing, while MOD users take more puffs daily; both groups experience health issues like shortness of breath when compared to non-users, highlighting significant differences based on device type.
Reliability of low mass toenail samples as biomarkers of chronic metal exposure.

Background: Toenails are a promising matrix for chronic metal exposure assessment, but there are currently no standard methods for collection and analysis. Questions remain about sample mass requirements and the extent to which metals measured in this matrix are representative of chronic body burden.
Objective: This study proposes a method to maximize sample conservation for toenail metals analysis using inductively coupled plasma mass spectrometry (ICP-MS).
Low-cost sensors enable finer-scale spatiotemporal measurements within the existing methane (CH) monitoring infrastructure and could help cities mitigate CH emissions to meet their climate goals. While initial studies of low-cost CH sensors have shown potential for effective CH measurement at ambient concentrations, sensor deployment remains limited due to questions about interferences and calibration across environments and seasons. This study evaluates sensor performance across seasons with specific attention paid to the sensor's understudied carbon monoxide (CO) interferences and environmental dependencies through long-term ambient co-location in an urban environment.

Methods: Integrated PM and PM Harvard Impactors were set up at six locations in the Baltimore City metropolitan area in weeklong sampling sessions from January-July 2019 to assess variation in airborne metal concentration by proximity to suspected metal emission sources. PM and PM were collected on Teflo filters and analyzed for a panel of 12 metals and metalloids (As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, and Zn) using inductively coupled plasma mass spectrometry.
