Background: The concentration of circulating total homocysteine is a sensitive marker of inadequate folate and vitamin B12 status. Elevated homocysteine concentrations are associated with an increased risk for vascular disease.
Objective: To identify reference ranges for serum total homocysteine concentration in U.S. residents and quantify the contribution of circulating vitamin concentrations to high homocysteine concentrations.
Patients: A nationally representative sample of 3563 male participants and 4523 female participants 12 years of age or older who participated in the third National Health and Nutrition Examination Survey.
Measurements: Reference ranges (5th and 95th percentiles) for the total homocysteine concentration were defined among participants who were folate- and vitamin B12-replete and had normal creatinine concentrations. A high total homocysteine concentration was defined as one that exceeded the sex-specific 95th percentile for the reference sample (participants 20 to 39 years of age). The population attributable risk percentage was calculated to determine the contribution of low folate (
Results: Reference ranges for serum total homocysteine concentration increased with age; these ranges were 4.3 to 9.9 micromol/L for male participants and 3.3 to 7.2 micromol/L for female participants 12 to 19 years of age and from 5.9 to 15.3 micromol/L for men and 4.9 to 11.6 micromol/L for women 60 years of age or older. A high homocysteine concentration was defined as at least 11.4 micromol/L for male participants and at least 10.4 micromol/L for female participants. Approximately two thirds of the cases of high homocysteine concentrations were associated with low vitamin concentrations.
Conclusions: Upper reference limits for the serum total homocysteine concentration increased with age and were higher for male participants than for female participants at all ages. In most cases, high homocysteine concentrations were associated with low serum vitamin concentrations.
While you may have heard them referred to as stimulus checks, the Economic Impact Payments were for the most part direct deposited into bank accounts or sent out as bank cards. More than 476 million payments totaling $814 billion in financial relief went to households impacted by the pandemic. The Internal Revenue Service (IRS) based the amounts that individuals received on income, tax filing status, and number of children (or qualifying dependents, like a relative).
EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks. This annual report estimates the total national greenhouse gas emissions and removals associated with human activities across the United States by source, gas, and economic sector.
Since 1990, gross U.S. greenhouse gas emissions have decreased by just over 2%. From year to year, emissions can rise and fall due to changes in the economy, the price of fuel, and other factors. In 2021, U.S. greenhouse gas emissions increased 5% compared to 2020 levels. In 2020, there was a sharp decline in emissions largely due to the impacts of the coronavirus (COVID-19) pandemic on travel and other economic activity. In 2021, the increase in total greenhouse gas emissions was driven largely by an increase in CO2 emissions from fossil fuel combustion due to economic activity rebounding after the height of the COVID-19 pandemic. In 2021, CO2 emissions from fossil fuel combustion increased by 7% relative to the previous year. CO2 emissions from natural gas consumption increased by less than 1 % relative to 2020. In a shift from recent trends, CO2 emissions from coal consumption increased by 15% from 2020. The increase in natural gas consumption and emissions in 2021 is observed across all sectors except the Electric Power sector and U.S. Territories, while the coal increase is primarily in the Electric Power sector. Emissions from petroleum use also increased by 9% in 2021, and CO2 emissions from fossil fuel combustion were 2% below emissions in 1990.
In 2021, the electric power sector was the second largest source of U.S. greenhouse gas emissions, accounting for 25% of the U.S. total. Electric power sector emissions increased 7% in 2021. Greenhouse gas emissions from electric power production have decreased by about 15% since 1990 due to a shift in generation to lower- and non-emitting sources of electricity generation and an increase in end-use energy efficiency.
In 2021, greenhouse gas emissions from transportation accounted for 28% of total U.S. greenhouse gas emissions, making it the largest contributor of U.S. greenhouse gas emissions. From 1990 to 2021, total transportation emissions from fossil fuel combustion increased by 19%. In 2021, emissions increased by 12%, which followed a decline of 13% in 2020 due to reduced travel demand during the height of the COVID-19 pandemic. The largest sources of transportation greenhouse gas emissions in 2021 were light-duty trucks, which include sport utility vehicles, pickup trucks, and minivans (37%); medium- and heavy-duty trucks (23%); passenger cars (21%); commercial aircraft (7%); other aircraft (2%); pipelines (4%); ships and boats (3%); and rail (2%). In terms of the overall trend, from 1990 to 2021, total transportation emissions have increased due, in large part, to increased demand for travel. The number of vehicle miles traveled (VMT) by light-duty motor vehicles (passenger cars and light-duty trucks) increased by 45% from 1990 to 2021, as a result of a confluence of factors including population growth, economic growth, urban sprawl, and periods of low fuel prices. Between 1990 and 2004, average fuel economy among new vehicles sold annually declined, as sales of light-duty trucks increased. Starting in 2005, average new vehicle fuel economy began to increase, while light-duty VMT grew only modestly for much of the period. Average new vehicle fuel economy has improved almost every year since 2005, slowing the rate of increase of CO2 emissions.
Direct emissions are produced by burning fuel for power or heat, through chemical reactions, and from leaks from industrial processes or equipment. Most direct emissions come from the consumption of fossil fuels for energy. A smaller amount of direct emissions, roughly one third, come from leaks from natural gas and petroleum systems, the use of fuels in production (e.g., petroleum products used to make plastics), and chemical reactions during the production of chemicals, metals (e.g., iron and steel), and minerals (e.g., cement).
In 2021, direct industrial greenhouse gas emissions accounted for 23% of total U.S. greenhouse gas emissions, making it the third largest contributor to U.S. greenhouse gas emissions, after the Transportation and Electric Power sectors. From 2020 to 2021, total energy use in the industrial sector increased by just over 1%. Including both direct emissions and indirect emissions associated with electricity use, industry's share of total U.S. greenhouse gas emissions in 2021 was 30%, making it the largest contributor of greenhouse gas emissions of any sector. Total U.S. greenhouse gas emissions from industry, including electricity, have declined by 14% since 1990.
In 2021, direct greenhouse gas emissions from homes and businesses accounted for 13% of total U.S. greenhouse gas emissions. Greenhouse gas emissions from homes and businesses vary from year to year, often correlated with annual fluctuations in energy use caused primarily by weather conditions. Total residential and commercial greenhouse gas emissions, including direct and indirect emissions, in 2021 have decreased by 2% since 1990. Greenhouse gas emissions from on-site direct emissions in homes and businesses have increased by 2% since 1990. Additionally, indirect emissions from electricity use by homes and businesses increased from 1990 to 2007 but have decreased since then to approximately 4% below 1990 levels in 2021.
In 2021, greenhouse gas emissions from the agriculture sector accounted for 10% of total U.S. greenhouse gas emissions. Greenhouse gas emissions from agriculture have increased by 7% since 1990. Agricultural soil management activities, such as application of synthetic and organic fertilizers, deposition of livestock manure, and growing nitrogen fixing plants, were the largest contributors to U.S. N2O emissions in 2021, accounting for 75% of total N2O emissions. Emissions from other agricultural sources have generally remained flat or changed by a relatively small amount since 1990.
In 2021, the net CO2 removed from the atmosphere from the LULUCF sector was 12% of total U.S. greenhouse gas emissions. Between 1990 and 2021, total carbon sequestration in the LULUCF sector decreased by 14%, primarily due to a decrease in the rate of net carbon accumulation in forests, as well as an increase in CO2 emissions from urbanization. Additionally, while episodic in nature, increased CO2, CH4 and N2O emissions from forest fires have also occurred over the time series.
In 2022, the U.S. experienced 18 separate weather and climate disasters costing at least 1 billion dollars. That number puts 2022 into a three-way tie with 2017 and 2011 for the third-highest number of billion-dollar disasters in a calendar year, behind the 22 events in 2020 and the 20 events in 2021. It was another year with a high diversity of destructive disasters:
Damages from the 2022 disasters totaled $165.1 billion. (All cost estimates are adjusted based on the Consumer Price Index, 2022). The costliest 2022 events were Hurricane Ian ($112.9 billion) and the Western and Central Drought / Heat Wave ($22.1 billion). Adding the 2022 events to the record that began in 1980, the U.S. has sustained 341 weather and climate disasters with the overall damage costs reaching or exceeding $1 billion. The cumulative cost for these 341 events exceeds $2.475 trillion.
