Microplastic in Clouds


Microplastic in cloud

Small plastic particles known as microplastics, which are frequently smaller than 5 mm in size, are present in a variety of settings, including water, air, and even some food products. Exposure to microplastics may have short- and long-term negative impacts, while more research is still needed to determine the full range of their effects on human health.

New research on microplastics in clouds was published by Japanese researchers. This investigation was conducted by Waseda University Professor Hiroshi Okochi to learn more about the movement of microplastics in the biosphere.

They discovered that the microplastics had a negative influence on both human health and the climate. As stated by Okochi on the official Waseda University website on September 27, "Microplastics in the free troposphere are transported and contribute to global pollution."

'Plastic air pollution' would be proactively tackled. If not, ecological dangers and climate change may materialize, resulting in long-term, severe environmental damage.

The group gathered cloud water from Mount Fuji's and Mount Oyama's summits, which are located in regions with elevations between 1,300 and 3,776 meters. Okochi and his team identified the existence of microplastics in the cloud water and investigated their physical and chemical characteristics using cutting-edge imaging techniques like attenuated total reflection imaging and micro-Fourier transform infrared spectroscopy (FTIR ATR imaging).

They consequently discovered nine various polymer kinds and one type of rubber among the airborne microplastics found. These microplastics have Feret diameters between 7.1 and 94.6 m, the lowest yet recorded in the free troposphere.

According to Aljazeera, each liter of cloud water examined had 6.7 to 13.9 plastic bits. Microplastics or tiny plastic particles under 5 millimeters in size, have already were found in fish, dotting Arctic sea ice, and in the snow on the Pyrenees mountains between France and Spain. They are made up of industrial waste, textiles, synthetic car tires, personal care products, and other sources.

Although there has been little research on the mechanics of their transportation to such a wide range of locales, it is unknown how microplastics are transported through the air.

Research has indicated that significant levels of microplastics are consumed or inhaled by people and animals, and have been found in numerous organs including the lungs, heart, blood, placenta, and feces, according to a statement made on Wednesday by Waseda University.

Short-term Harmful Effects

Inflammation Microplastics may cause respiratory or gastrointestinal tract inflammation upon consumption or inhalation, resulting in pain and potential medical problems.

Allergies Some people may develop allergies to specific chemicals or additives present in microplastics, which might irritate their skin or create breathing issues.

GI distress and discomfort Accidental ingestion of microplastics through tainted food or beverages may result in transient gastrointestinal distress such nausea, bloating, or diarrhea.

Physical Irritation Microplastics that are inhaled might irritate the throat and nasal passages, which can lead to coughing, sneezing, or itchy throat.

Long-term Harmful Effects

Exposure to Toxic substances Microplastics can take in and transport harmful substances from the environment. Chronic health difficulties, including as cancer and reproductive disorders, may become more likely if microplastics are consumed over an extended period of time and expose people to these substances.

Disruption of the gut microbiome There is data that suggests microplastics in the gastrointestinal tract may upset the balance of the gut microbiota, possibly causing digestive problems and immune system malfunction.

Bioaccumulation Microplastics may build up in the body over time, especially in the tissues and organs. This buildup could result in persistent inflammation and harm to important organs.

Hormonal Disruption Phthalates and bisphenol A (BPA), two chemicals that are present in microplastics, are well-known endocrine disruptors. The risk of hormonally-related health problems may grow with prolonged exposure to these chemicals, which may disrupt hormonal balance.

Respiratory Problems Asthma and chronic obstructive pulmonary disease (COPD) may be exacerbated by long-term exposure to airborne microplastics, particularly in working settings.

Microplastics' potential negative impacts on the environment and on human health can cause psychological tension and anxiety, which can have a long-term negative influence on mental health.

It's crucial to remember that scientific knowledge of microplastics' effects on human health is still developing, and more study is necessary to properly comprehend the degree of such effects. Potential dangers can be reduced by reducing plastic pollution and exposure to microplastics through dietary decisions and environmental regulations.

Inferred was that microplastics may now be a necessary part of clouds, polluting almost all of our food and drink through "plastic rainfall." In addition to extensive environmental harm, new research has connected microplastics to a variety of effects on heart and lung health, as well as malignancies.
