Jakarta, Indonesia – A recent study by the National Research and Innovation Agency (BRIN) has revealed the unsettling presence of microplastics in rainwater samples collected throughout Jakarta. This discovery underscores a worrying trend: plastic pollution is no longer confined to our oceans and waterways, but is now circulating in the atmosphere, posing a potential risk to human health and the environment.
The Scope of the Problem
Researchers at BRIN began investigating atmospheric microplastic deposition in 2022, and their findings, released on Saturday, October 18, 2025, demonstrate that every rainwater sample analyzed contained microscopic plastic particles. These insidious particles originate from the breakdown of larger plastic debris, exacerbated by human activities, according to Muhammad Reza Cordova, a BRIN researcher.
The primary sources of these airborne microplastics include synthetic clothing fibers released during washing, dust generated from vehicle and tire wear, residue from the burning of plastic waste, and the general degradation of plastics exposed to the elements. The study identified common polymers like polyester, nylon, polyethylene, polypropylene, and polybutadiene – commonly found in tires – as the predominant components of these airborne particles.
Atmospheric Deposition: A New Pathway for Pollution
The research highlights a previously underestimated pathway for plastic pollution: atmospheric microplastic deposition. Microplastics, lightweight enough to be carried by wind currents, are lifted into the air from various sources and subsequently return to earth via rainfall. “The plastic cycle doesn’t stop in the sea,” explains Cordova. “It goes up into the sky,travels around with the wind,then comes back down to earth through rain.”
On average,researchers detected approximately 15 microplastic particles per square meter per day in rainwater samples collected in Jakarta’s coastal areas. This suggests that the city’s dense population and high levels of activity contribute significantly to the problem. According to a 2024 report by the National Geographic, globally, an estimated 8 million metric tons of plastic enter the oceans each year, contributing to the ongoing cycle of degradation and atmospheric transport.
Health Concerns and Potential Impacts
The size of these microplastics is especially concerning. Being finer than typical dust particles, they can be readily inhaled, or ingested through contaminated water and food sources. Beyond the physical presence of the particles themselves, plastics often contain possibly harmful additives such as phthalates, bisphenol A (BPA), and heavy metals. These substances can leach into the environment as the plastic breaks down, and the airborne particles can also act as carriers for other pollutants like aromatic hydrocarbons from vehicle exhaust.
while further research is needed to fully understand the long-term health effects, studies globally suggest potential impacts including oxidative stress, hormonal disruption, and tissue damage.
Jakarta’s Response and Future Steps
The DKI Jakarta Environmental Service (DLH) has announced its intention to collaborate with BRIN to address this emerging issue. Asep Kuswanto, Head of DLH DKI Jakarta, emphasized the need for a collaborative, cross-sectoral approach to combat plastic pollution in all its forms. The DLH is strengthening plastic waste management programs,from upstream reduction to downstream control,and expanding air and rainwater quality monitoring initiatives.
Current policies include Governor’s Regulation Number 142 of 2019,mandating the use of environmentally friendly shopping bags,and the Jakstrada Waste Program,aiming for a 30 percent reduction in waste at the source. Efforts are also underway to expand waste banks, 3R TPS (Reduce, Reuse, Recycle facilities), and community-based recycling programs.
DLH is integrating microplastic monitoring into the Jakarta Environmental Data Integration (JEDI) system – a data-driven platform for environmental quality monitoring – to inform future policy decisions.
| Source of microplastics | Estimated Contribution |

| Synthetic Clothing Fibers | Significant, especially from washing machines |
| Vehicle & Tire Wear | Major contributor in urban areas |
| Burning of Plastic Waste | Significant, particularly in areas with open burning |
| plastic Degradation | Ongoing process contributing to atmospheric build-up |
Understanding Microplastics: A Deeper dive
Microplastics are defined as plastic particles less than 5 millimeters in diameter. They are categorized as primary microplastics-those manufactured at microscopic size for use in products like cosmetics and industrial abrasives-and secondary microplastics,which result from the breakdown of larger plastic items. The persistence of plastics in the environment,coupled with their ubiquitous use,means microplastic pollution is a global concern that demands ongoing attention and innovative solutions.

Microplastics in Jakarta Rain: Potential Environmental and Health Implications
Sources and Types of microplastics in Jakarta’s rainfall
Jakarta, Indonesia, a megacity grappling with rapid urbanization and significant plastic pollution, is increasingly facing the issue of microplastics in rainwater. These tiny plastic particles, less than 5mm in diameter, originate from a multitude of sources.identifying these sources is crucial for effective mitigation strategies.
* Fragmented Plastic Waste: The breakdown of larger plastic debris – bottles, bags, packaging – due to UV radiation, mechanical abrasion, and biological degradation is a primary contributor.Jakarta’s waste management challenges exacerbate this.
* Textile Fibers: Washing synthetic clothes releases microfibers, a significant type of microplastic, which are carried through wastewater systems and can end up in rainwater runoff.
* Tire Wear Particles: Vehicle traffic contributes significantly, with tyre abrasion releasing particles that are washed into drainage systems during rainfall.
* Cosmetics & Personal Care Products: Many contain microbeads (though increasingly regulated), which enter waterways through wastewater.
* Industrial Effluents: Plastic manufacturing and processing industries can release microplastics directly into the surroundings.
Common types of microplastics found in Jakarta’s rainwater include polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET) – all commonly used in packaging and everyday items. Recent studies have also identified the presence of polyvinyl chloride (PVC) and nylon.
Environmental Impacts on Jakarta’s Ecosystems
The presence of microplastic pollution in Jakarta’s rainwater has cascading effects on the local environment.
* Water Contamination: Microplastics contaminate surface water, impacting rivers like the Ciliwung and the surrounding coastal waters. This affects aquatic life and potentially drinking water sources.
* Soil Pollution: Rainwater carries microplastics into agricultural lands, altering soil composition and potentially hindering plant growth. Soil microplastics can also affect soil microorganisms.
* Impact on Aquatic Life: Microplastics are ingested by fish, shellfish, and other aquatic organisms, leading to physical harm, bioaccumulation of toxins, and disruption of the food chain. Studies show Jakarta Bay already exhibits significant microplastic contamination in marine organisms.
* Impact on Mangrove Ecosystems: Jakarta’s coastal mangrove forests, vital for coastal protection and biodiversity, are especially vulnerable. Microplastics can accumulate in mangrove sediments, affecting root health and overall ecosystem function.
* Bioaccumulation & Biomagnification: Microplastics absorb pollutants from the surrounding environment. As they move up the food chain, these pollutants become more concentrated in larger organisms, posing risks to both wildlife and humans.
