Impacts of Microplastics and Nanoplastics on Tomato Crops: A Critical Review
AI summary Read the abstract
This review covers the impacts of microplastics and nanoplastics on tomato crops, documenting disruption at germination, root development, flowering, and fruit production stages. It also examines how these particles alter soil microbial communities and identifies priority research areas for understanding MP effects on major food crops.
The growing prevalence of plastic pollution has raised significant environmental concerns, particularly regarding microplastics and nanoplastics that persist in various ecosystems. As these particles accumulate in terrestrial environments, their potential impact on crop health and growth has become a growing area of focus. Ongoing studies show that microplastics and nanoplastics can disrupt various stages of crop development. Therefore, several studies are currently being conducted on the impact of microplastics and nanoplastics on the germination, growth, and productivity of various crops, highlighting the tomato (Solanum lycopersicum) crop. Although several studies have explored the effects of microplastics and nanoplastics on tomato crops, a comprehensive review of their impacts is still lacking. Therefore, this manuscript presents a detailed review regarding the influence of microplastics and nanoplastics on tomato cultivation. This review revealed that most studies have primarily focused on assessing the effects of microplastics on tomato crop germination, physiological growth, yield, and fruit quality. Therefore, it is essential to conduct further research addressing the impact of nanoplastics on these same aspects.

MICROPLÁSTICOS Y NANOPLÁSTICOS: UNA REVISIÓN SISTEMÁTICA DE SU IMPACTO EN EL CRECIMIENTO DE TOMATE (Solanum lycopersicum)
AI summary Read the abstract
This systematic review analysed published studies on the effects of synthetic microplastics and nanoplastics on tomato (Solanum lycopersicum) growth, examining how polymer type, particle size, concentration, and growth medium modulate phytotoxicity. The review found that MP and NP exposure consistently impaired biomass accumulation, plant height, flower and fruit production, and root and shoot length, with higher concentrations and smaller particle sizes generally producing the most pronounced negative effects.

AI summary Read the abstract
This review examines the growing body of evidence on how microplastics and nanoplastics affect plant health, soil microbial communities, and agricultural productivity. The study highlights that plastic accumulation in agricultural soils can alter crop growth and yield while disrupting soil ecosystem dynamics, and calls for greater attention to agro-ecotoxicology management to address these emerging threats to food production.
Effects of microplastics polluted soil on the growth of Solanum lycopersicum L.
AI summary Read the abstract
This study tested how microplastic-contaminated soil affects tomato plant growth, finding that higher concentrations of plastic particles in soil reduced plant height, root development, and overall crop health. The results suggest that microplastic pollution in farmland could reduce food crop yields and potentially affect the quality of the produce we eat.
Microplastics reshape rhizosphere microbial communities and nutrient cycling in tomato agroecosystems
AI summary Read the abstract
Tiny plastic particles from pollution are seeping into farm soil and disrupting the natural microbes that help tomato plants absorb nutrients like nitrogen and phosphorus. This research found that different types of plastic (like those from packaging and pipes) throw off soil chemistry and bacterial activity in ways that could affect how healthy and nutrient-rich our food crops grow. While this study looked at soil, not food safety directly, it adds to growing evidence that microplastic pollution may be quietly affecting the food system from the ground up.
