Occurrence and Characteristics of Microplastics in in a Ship’s Greywater According to Usage Patterns
This study sampled greywater from different ship compartments — galleys, laundries, showers, and washbasins — and found that microplastics were present in all compartments, with laundry being the largest source. The results show that ships discharge significant quantities of microplastics through greywater, which can be legally released directly to the sea in most ocean zones. The findings highlight ships as an important but underregulated source of marine microplastic pollution.
Treatment of greywater and presence of microplastics in on-site systems
Researchers investigated microplastic occurrence in on-site wastewater treatment systems used for greywater, finding that these decentralized systems do not fully remove microplastics before discharge. The study highlights a poorly studied pathway for microplastics entering the environment.
Occurrence and characteristics of microplastics in greywater from a research vessel
Microplastics were found in greywater from a research vessel across multiple water usage types, with laundry water showing the highest microplastic concentrations, identifying ships as an underappreciated sea-based source of microplastic pollution.
A Review of the Current Literature on Sources and Mitigation Strategies of Microplastics in Drinking Water
Researchers reviewed the key sources of microplastic contamination in drinking water — including plastic waste, synthetic clothing, and microbeads in personal care products — and assessed strategies for reducing exposure through improved treatment technologies and stricter regulations on plastic production. The review emphasizes that effective policy, combined with public awareness about single-use plastics, is essential for protecting drinking water quality.
Assessment of Microplastic Abundance and Discharge from Greywater of Ships
Researchers quantified microplastics in ship greywater from showers, washbasins, laundry, and dishwashers and found that laundry sources produced the highest microplastic concentrations. Since greywater can be discharged to the sea without treatment in most areas, ships contribute substantially to marine microplastic pollution. The study supports the case for regulating greywater discharge from vessels.
Insights into Global Water Reuse Opportunities
This review examines global opportunities and challenges for reusing treated wastewater, which is becoming increasingly important as water scarcity worsens worldwide. A key concern discussed is that recycled water may contain emerging contaminants including microplastics that current treatment methods do not fully remove. The findings highlight the need for advanced treatment technologies to ensure that water reuse does not become a pathway for microplastic exposure in communities.
Treated wastewater irrigation: unlocking sustainability in agriculture and food security—a comprehensive review
This comprehensive review explores treated wastewater as an alternative irrigation source for agriculture in water-scarce regions. While treated wastewater can improve soil fertility and crop growth, the review notes concerns about contaminants including microplastics that can accumulate in soil and potentially enter the food chain, emphasizing the need for effective treatment technologies.
Microplastics in wastewaters and their potential effects on aquatic and terrestrial biota
This review of over 200 studies found that microplastics from wastewater are contaminating both aquatic and land environments, especially when treated wastewater or sewage sludge is used for irrigation. The microplastics can harm fish, soil organisms, plants, and microbial communities, and they serve as carriers for other toxic pollutants. The findings highlight that wastewater is a major pathway through which microplastics reach farmland and, ultimately, human food and drinking water.
Impact of Wastewater on the Soil–Plant–Atmosphere Interface: Challenges and Remediation Approaches
This review examines the wide-ranging impacts of using wastewater for agricultural irrigation, covering effects on soil health, crop safety, and greenhouse gas emissions. Among the many concerns discussed, microplastics and antibiotic-resistant bacteria emerging from wastewater reuse are flagged as growing threats requiring better monitoring and policy responses. For readers interested in microplastics, the paper highlights how irrigation with wastewater is one of the pathways by which plastic particles enter farmland soils and ultimately the food chain.
Sources and Leakages of Microplastics in Cruise Ship Wastewater
Researchers investigated microplastic sources and leakages from cruise ship wastewater systems, finding that onboard laundry, food waste processing, and sewage treatment all contribute microplastics to discharge, with poorly filtered grey water representing a significant and underregulated pathway to the ocean.
Perception and impact of micropollutants in urine-based liquid fertilizer on crop production: A comprehensive review of Eco-sanitation practices
This review explores the promise and risks of using human urine as a crop fertilizer, noting it contains valuable nitrogen and phosphorus but also pharmaceuticals, heavy metals, and microplastics that can contaminate soil and enter food crops. The presence of microplastics in urine-derived fertilizer is identified as a safety concern that adds to the already complex risk calculus of eco-sanitation practices. The paper underscores how microplastics have permeated even novel, low-tech agricultural inputs, complicating otherwise sustainable approaches.
