Microplastics: The Silent Threat Lurking Beneath Long Island’s Landscapes
Long Island’s lush gardens and agricultural landscapes face an invisible enemy that’s quietly infiltrating our soil systems. Microplastic contamination, once primarily associated with ocean pollution, has emerged as a critical threat to plant health across the region. Recent studies have identified microplastic hotspots in Long Island Sound waters, with over half of detected microplastics being synthetic fibers like polyester and nylon, alongside polypropylene fragments. This contamination doesn’t stay confined to waterways—it’s making its way into our terrestrial ecosystems, creating cascading effects on plant health that every Long Island property owner should understand.
Understanding the Microplastic Problem on Long Island
Microplastics are defined as particles smaller than 5 mm that result from the breakdown of larger plastic debris or are manufactured at microscopic scales, pervading ecosystems such as freshwater and marine environments, soils, and the atmosphere. Around 80% of marine plastics originate from land-based sources, and microplastic concentrations in soil are estimated to be 4 to 23 times higher than in marine systems.
For Long Island residents, this contamination hits particularly close to home. Agricultural land, covering approximately 38% of the Earth’s surface, is particularly vulnerable to microplastic pollution due to practices such as plastic mulching, sewage sludge application, and irrigation. The region’s extensive use of synthetic materials in landscaping, combined with coastal proximity to contaminated waters, creates a perfect storm for microplastic accumulation in local soils.
How Microplastics Devastate Plant Health
The impact of microplastics on plant health is both immediate and long-term. Microplastics pose a threat to plants by inhibiting seed germination, root elongation, and nutrient absorption, while their accumulation induces oxidative stress, cytotoxicity, and genotoxicity in plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, and metabolite production in plant tissues.
Studies suggest that the presence of microplastics in soil hampers seed germination and seedling growth, with vital physiological processes of plants being disturbed, impacting the yield and quality of produce through reduced rate of photosynthesis, stunted growth, decreased fruit yield and low nutritional content of fruits and vegetables.
The contamination doesn’t stop at the root level. Roots can absorb nanoplastics, which are then distributed to stems, leaves, and fruits, with microplastics being passed on to humans when fruits and vegetables contaminated with microplastics are eaten. Microplastics have been reported in apples, pears, carrots, lettuce, onions, tomatoes, cucumbers and many other commonly consumed fruits and vegetables.
The Soil Health Crisis
Microplastics harm soil health by reducing microbial diversity, which disrupts the root ecosystem, decreases soil fertility and interferes with the movement of nutrients, while also interacting with other contaminants, such as pesticides, increasing their concentration and toxicity in the soil. Microplastics can affect biophysical properties of the soil, with little known about the cascade of events in fundamental levels of terrestrial ecosystems, starting with changes in soil abiotic properties and propagating across various components of soil–plant interactions, including soil microbial communities and plant traits.
This soil degradation creates a vicious cycle. The presence of microplastics can prevent the proper absorption of nutrients and water by plant roots, changing the biomass of plants, the characteristics of the roots, and microbial activities at the soil level.
