Fine particulate matter (PM2.5) air pollution exposure is associated with short and long-term health effects. Several studies found differences in PM2.5 neighborhood racial socioeconomic composition. However, most focused on total mass rather than its chemical components their sources. In this study, we describe the ZIP code characteristics that drive disparities to attributed source categories both nationally regionally. We obtained annual mean predictions of fourteen from spatiotemporal models predictor variables 2010 US Census, American Community Survey 5-year estimates. used non-negative matrix factorization attribute five categories. fit generalized nonlinear assess associations between predictors each category urban areas United States (n = 25,790 zip codes). observed higher levels codes proportions Black individuals lower status. Racial were mainly Heavy Fuel, Oil Industrial, Metal Processing Industry Agricultural, Motor Vehicle Economic Soil Crustal Dust, Fuel Upon further analysis through stratifying by regions within States, source-attributed generally greater Western states. conclusion, racial, socioeconomic, geographic inequalities are driven systematic component sources can inform quality improvement strategies.

Background Fine particulate matter <2.5 µm in diameter (PM 2.5 ) has known effects on cardiovascular morbidity and mortality. However, no study quantified compared the risks of incident myocardial infarction, stroke, ischemic heart disease (IHD) mortality, cerebrovascular mortality relation to long‐term PM exposure. Methods Results We sought quantitatively summarize studies exposure risk IHD stroke events by conducting a review meta‐analysis published December 31, 2019. The main outcomes were Random meta‐analyses used estimate combined each outcome among studies. reviewed 69 included 42 meta‐analyses.

Air pollution exerts several deleterious effects on the cardiovascular system, with disease (CVD) accounting for 80% of all premature deaths caused by air pollution. Short-term exposure to particulate matter 2.5 (PM2.5) leads acute CVD-associated and nonfatal events, whereas long-term increases risk death reduces longevity. Here, we summarize published data illustrating how PM2.5 may impact system provide information mechanisms which it contribute CVDs. We an overview PM2.5, its associated health risks, global statistics, mechanistic underpinnings related mitochondria, hazardous biological effects. elaborate association between CVD development examine preventive measures future strategies combating PM2.5-related adverse The insights gained can critical guidelines preventing pollution-related CVDs through governmental, societal, personal measures, thereby benefitting humanity slowing climate change.

Microplastics have been observed in indoor and outdoor air. This raises concern for human exposure, especially should they occur small enough sizes, which if inhaled, reach the central airway distal lung. As yet, methods their detection not spectroscopically verified chemical composition of microplastics this size-range. One proposed method is an automated spectroscopic technique, Raman spectral imaging; however, generates large complex data sets. study aims to optimize imaging identification (≥2 μm) ambient particulate matter, using different chemometric techniques. We show that images analyzed statistical approaches are appropriate both virgin environmental ≥2 μm size. On basis sensitivity, we recommend developed Pearson's correlation agglomerative hierarchical cluster analysis Finally, applicability by identifying airborne >4.7 matter sample obtained at urban sampling site London, United Kingdom. semiquantitative will enable procurement exposure concentrations guiding future toxicological assessments.

Particulate matter (PM), an important component of air pollution, induces significant adverse health effects. Many the observed effects caused by inhaled PM are associated with oxidative stress and inflammation. This association has been linked in particular to particles' chemical components, especially inorganic/metal organic/polycyclic aromatic hydrocarbon (PAH) fractions, their ability generate reactive oxygen species biological systems. The transcription factor NF-E2 nuclear erythroid-related 2 (Nrf2) is activated redox imbalance regulates expression phase II detoxifying enzymes. Nrf2 plays a key role preventing PM-induced toxicity protecting against damage review focuses on specific particularly dissolved metals PAH roles inducing inflammation cell animal models respect mitochondria.
