The application of nuclear technique for measuring the bioaccumulation of microplastic in oyster (Crassostera Gigas)
Summary
Researchers used nuclear techniques with radioiodine (131I)-labeled polystyrene to measure the bioaccumulation of microplastics in Pacific oysters (Crassostera gigas), examining how salinity levels and microplastic concentrations affect bioaccumulation and elimination kinetics using a single-compartment biokinetic model.
Abstract This study aims to determine the effect of salinity and microplastic concentration on the bioaccumulation ability of microplastics in oyster ( Crassostera Gigas ) using nuclear techniques. Biokinetic experiments were conducted using a single-compartment approach utilizing 131 I. The biokinetic experiment methods were biota collection, acclimatization, bioaccumulation, and elimination. Bioaccumulation was carried out by placing the biota in an aquarium containing seawater media spiked with PSS- 131 I with concentrations of 0.96, 1.93, and 3.85 mg L −1 and salinity differences of 30, 32, and 34 g L −1 for seven days and depuration for seven days by placing the organism in media without microplastics. The experimental results showed that the highest uptake value (CF) was in the 3.85 mg L −1 concentration treatment, which was 3.1 × 10 −5 mL g −1 and in the depuration process could maintain PSS- 131 I by 47 %. In the salinity treatment, the highest CF was at a salinity of 34 g L −1 with a value of 4 × 10 −5 mL.g-1. In the depuration process, it can maintain PSS- 131 I by 43 %. The experimental results showed that the bioaccumulation rate of PSS- 131 I was affected by salinity and concentration. Concentration and salinity were directly proportional to the increase in bioaccumulation.

Application of nuclear analysis for bioaccumulation of microplastics with iodine-131 in marine organisms
Researchers developed a method using iodine-131 labeled polystyrene to track microplastic accumulation in mangrove plants and milkfish through nuclear analysis. They found that both organisms absorbed the labeled microplastics, with accumulation patterns varying between plant roots and fish tissue. The study demonstrates that radiotracer techniques can be a valuable tool for understanding how microplastics move through marine food chains.

Combined effects of salinity and polystyrene microplastics exposure on the Pacific oysters Crassostrea gigas: Oxidative stress and energy metabolism
Researchers studied how salinity levels affect the toxicity of polystyrene microplastics in Pacific oysters and found that low salinity reduced microplastic uptake but created complex interactions with oxidative stress and energy metabolism. Smaller microplastics generally caused more biological disruption than larger ones across all salinity conditions. This is important because coastal oyster habitats frequently experience salinity changes, and the findings suggest environmental conditions can alter how harmful microplastics are to shellfish.
