Abstract

Microplastics (plastic particles <5 millimeters in diameter) have become a novel food contaminant for humans.Microplastics was estimated that children consume 106-113 microplastics per day and 126-142 particles in adults.The main prevention effort is to identify the presence of plastic particles in food, one of which is sugar. Microplasticsthat are in the digestive tract can enter the bloodstream and distributed to other parts of the body. These particlescannot be destroyed by the body's cellular mechanisms, thus triggering inflammation, genotoxicity, hypersensitivity,oxidative stress, and cell death. The aim of the study was to measure the number of particles, shape and diameter ofplastic particles as contaminants in refined sugar produced in Indonesia. Quantitative descriptive research using 16sugar brands that are produced, known and widely consumed in Indonesia. The research was carried out at theClinical Pathology Laboratory, Widya Mandala Surabaya Catholic University. Quantification of the number, shapeand diameter of plastic particles using a microscope. The examination results showed that all sugar samples containedplastic particles between 5-100 MPs/50 gram of sugar, most of the contaminants were in the form of pellets, and thelargest particle diameter was 367µm.

Abstract

Microplastics are a new pollutant in the air, but the determination of the maximum limit of their existence has not been set in regulations. Microplastics found in the air of building spaces are made from plastic waste. The presence of microplastics in the air is influenced by physical environmental factors. Inhaling microplastics can have a detrimental impact on lung tissue. The research aims to create a mathematical model of the effect of ultraviolet exposure, temperature, and humidity on the quantity of microplastics in indoor air. Mathematical models can be used to predict the quantity of microplastics in the air. The type of research is a true experiment with a posttest-only control group design. Air samples are taken daily for 60 days by the passive method by taking dustfall. The parameters measured include the quantity of microplastics, ultraviolet intensity, temperature, and air humidity. Microplastic examination by visual method using a 40-fold magnification binocular microscope. Analysis of the mathematical model of the effect of ultraviolet exposure, temperature, and humidity on the quantity of microplastics in the form of time series data using linear regression. The results of data analysis show that the effect of the panel regression estimation model, in accordance with the empirical data, is the Fixed Effect Model (FEM). The conclusion based on the results of the study shows that physical environmental factors have an influence on the quantity of microplastics in the air, whose existence can be predicted using FEM modeling that has been made.
