Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
Domestic combustion pollution is mainly composed of burning fuel including wood, gas, and charcoal in activities of heating, cooking, agriculture, and wildfires. [15] Major domestic pollutants contain 17% of carbon dioxide, 13% of carbon monoxide, 6% of nitrogen monoxide, polycyclic aromatic hydrocarbons, and fine and ultrafine particles. [16]
Human-produced aerosols such as particle pollution tend to have a smaller radius than aerosol particles of natural origin (such as windblown dust). The false-color maps in the map of distribution of aerosol particles on the right show where there are natural aerosols, human pollution, or a mixture of both, monthly.
The tiny pollutants emitted by fossil fuel combustion and wildfires may be raising the risk of adverse birth outcomes, a study has found. Exposure to fine particulate matter (PM 2.5) can cause ...
A new study found that soot nanoparticles inhaled by the mother can cross the placenta.
Looking down from the Hollywood Hills, with Griffith Observatory on the hill in the foreground, air pollution is visible in downtown Los Angeles on a late afternoon.. Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems.
Toxic "black carbon" air pollution particles inhaled during pregnancy have been found in the tissues and organs of fetuses, according to a new study. For 1st time, potentially toxic air pollution ...
Increased levels of fine particles in the air are linked to health hazards such as heart disease, [78] altered lung function and lung cancer; [79] a definitive link between fine particulate pollution and higher death rates in urban areas was established by the Harvard Six Cities study, published in 1993.
