聚苯乙烯（PS）由于其绝缘性能、光学透明性和长保质期而被大量用于一次性食品包装。尽管这些理想的特性，（PS）造成的毒性问题，人类的健康，通过苯乙烯单体浸出到食品。由于回收战略和设施不当和/或缺乏，环境和海洋危害是另一个日益令人关切的问题。这项初步工作的目的是调查的苯乙烯单体从聚（苯乙烯）食品接触材料迁移到食品模拟物的温度，食品成分和接触时间的影响。聚（苯乙烯）杯显示出相对较低的苯乙烯迁移水平，最高为0.110 µ g/mL，而食品容器显示出高得多的苯乙烯浸出水平，高达6 µ g/mL。这可能是由于从低脂肪含量到高脂肪含量的模拟物特征的疏水性增加以及测试温度从5 ° C增加到70 ° C。ANOVA统计分析用于比较三组或更多组数据的平均值，而t检验分析用于比较两组的平均值。对每个单独样品进行该操作，以确定改变温度、模拟物类型或两者对结果中观察到的迁移水平的显著性。在95%置信水平p <0.05下检验所有显著值，得出结论，发现脂肪含量和高温显著增加苯乙烯迁移水平。尼罗红染色方法用于证明颗粒聚苯乙烯以及苯乙烯单体从典型容器迁移到测试的食品模拟物中，随着微塑料摄入证据的增加，这正在成为令人担忧的原因。
Poly(styrene) (PS) has been heavily utilised in disposable food packaging due to its insulating properties, optical translucency, and long-shelf life. Despite these desirable characteristics, (PS) poses toxicity concerns to human’s health through styrene monomer leaching into foodstuffs. Environmental and marine hazards are another growing concerns due to improper and/or absence of recycling strategies and facilities. This preliminary work aims to investigate the effect of temperature, food composition and contact times on the migration of the styrene monomer from poly(styrene) food contact materials into food simulants. Poly(styrene) cups showed a relatively low level of styrene migration with the highest being 0.110 µg/mL, whereas food containers showed a much higher level of styrene leaching with up to 6 µg/mL. This could be due to an increase in the hydrophobicity of the simulants’ characteristics from low to high fat content and the increase in the testing temperatures from 5 °C to 70 °C. ANOVA statistical analysis is used to compare the means of three or more groups of data, whereas t-test analysis is used to compare means of two groups. This was carried out on each individual sample to determine the significance of changing the temperature, simulant type, or both on the level of migration observed in the results. All significant values were tested at 95% confidence level p < 0.05, concluding that fat content and high temperatures were found to significantly increase the level of styrene migration. Nile Red staining method was used to demonstrate that particulate poly(styrene), as well as styrene monomer, migrated into tested food simulants from typical containers, which is becoming a cause for concern as evidence of microplastic ingestion increases.
