Particulate matter (PM), particularly PM2.5, was found to be harmful to aquatic invertebrates. [41] These aquatic invertebrates include fish, crustaceans, and Mollusca. In a study by Han et al, the effects of PM<2.5 micrometers on life history traits and oxidative stress were observed in Tigriopus japonicus.
Overall labor effectiveness (OLE) is a key performance indicator (KPI) that measures the utilization, performance, and quality of the workforce and its impact on productivity. Similar to overall equipment effectiveness (OEE), OLE measures availability, performance, and quality.
Economic analysis also looks at the economics of climate change mitigation and the cost of climate adaptation. Mitigation costs will vary according to how and when emissions are cut. Early, well-planned action will minimize the costs. [5] Globally, the benefits of keeping warming under 2 °C exceed the costs. [6]
This index, reported by the Environmental Protection Department, is measured on a scale of 1 to 10+ and considers four air pollutants: ozone; nitrogen dioxide; sulfur dioxide and particulate matter (including PM10 and PM2.5). For any given hour the AQHI is calculated from the sum of the percentage excess risk of daily hospital admissions ...

The national AQHI is based on three-hour average concentrations of ground-level ozone (O 3), nitrogen dioxide (NO 2), and fine particulate matter (PM2.5). O 3 and NO 2 are measured in parts per billion (ppb) while PM2.5 is measured in micrograms per cubic metre (μg/m 3).
The Bureau of Labor was established within the Department of the Interior on June 27, 1884, to collect information about employment and labor. Its creation under the Bureau of Labor Act (23 Stat. 60) stemmed from the findings of U.S. Senator Henry W. Blair's "Labor and Capital Hearings", which examined labor issues and working conditions in the U.S. [6] Statistician Carroll D. Wright became ...
The labor force is the actual number of people available for work and is the sum of the employed and the unemployed. The U.S. labor force reached a record high of 168.7 million civilians in September 2024. [1] In February 2020, at the start of the COVID-19 pandemic in the United States, there were 164.6 million civilians in the labor force. [2]
