Summary: Microplastic pollution has emerged as a significant environmental concern in agricultural settings, where its occurrence, sources, and community awareness remain largely underexplored. This study addresses the critical research gap regarding the microplastic presence in Snow Cabbage (Brassica rapa) and Water Spinach (Ipomoea aquatica) grown on an urban farm in Quezon City. Given the city's dense population and the increasing popularity of urban farming, understanding microplastic contamination is essential for ensuring food quality and public health. The objectives aim to isolate, characterize, and identify microplastics from the agricultural soil, water, and plant tissues, to compare the morphology and polymer composition of the isolated MPs from all of the samples, and to assess the community's awareness of microplastic contamination. These objectives were accomplished via composite sampling (soil), manual grab sampling (water), purposive sampling (vegetable samples), and convenience and snowball sampling (survey). A total of 144 suspected microplastics were isolated from various samples, but only 86 microplastics were confirmed through FTIR analysis. The most frequently observed microplastics were color blue and predominantly fragment shaped. The majority of microplastics fell within Class 5, and FTIR identification revealed that Polyphenylene sulfide and Polyacrylamide were the most abundant types present across all samples. Farmer survey unveiled that many agricultural practices employed on farm might potentially contribute to microplastic contamination. While community survey results exhibit a positive perception and strong agreement among respondents regarding the farm’s role in enhancing food accessibility and quality, as well as a moderate level of environmental awareness about microplastic contamination.

Microplastic pollution has emerged as a significant environmental concern in
agricultural settings, where its occurrence, sources, and community awareness remain
largely underexplored. This study addresses the critical research gap regarding the
microplastic presence in Snow Cabbage (Brassica rapa) and Water Spinach (Ipomoea
aquatica) grown on an urban farm in Quezon City. Given the city's dense population and
the increasing popularity of urban farming, understanding microplastic contamination is
essential for ensuring food quality and public health. The objectives aim to isolate,
characterize, and identify microplastics from the agricultural soil, water, and plant
tissues, to compare the morphology and polymer composition of the isolated MPs from
all of the samples, and to assess the community's awareness of microplastic
contamination. These objectives were accomplished via composite sampling (soil),
manual grab sampling (water), purposive sampling (vegetable samples), and convenience
and snowball sampling (survey). A total of 144 suspected microplastics were isolated
from various samples, but only 86 microplastics were confirmed through FTIR analysis.
The most frequently observed microplastics were color blue and predominantly fragment
shaped. The majority of microplastics fell within Class 5, and FTIR identification
revealed that Polyphenylene sulfide and Polyacrylamide were the most abundant types
present across all samples. Farmer survey unveiled that many agricultural practices
employed on farm might potentially contribute to microplastic contamination. While
community survey results exhibit a positive perception and strong agreement among
respondents regarding the farm’s role in enhancing food accessibility and quality, as well
as a moderate level of environmental awareness about microplastic contamination.
