由于塑料在许多应用中的通用性，它越来越多地用于消费品。然而，这些塑料可能含有对人体有害的无机元素。为了确定塑料的任何潜在健康风险，必须确定塑料的元素组成特征并评估其使用模式。调查典型牙买加家庭的塑料使用情况，并使用XRF分析仪表征消费塑料中的无机元素。为了确定塑料的种类和数量，向住户发放了约200份调查问卷。共收集了7个类别的130个塑料样品，并使用手持式XRF测量了无机元素。家用塑料主要用于储存和个人卫生用品。平均而言，10%的塑料被回收利用，30%被焚烧。无机元素出现在塑料样本Cl > Ti英航> >铁>锌> >某人Cr > Br >铜> V >铅>。元素浓度因塑料的种类而异。绿色塑料中每种元素的浓度最高。这项研究提供了有用的信息表征不同类型的元素存在于普通家用塑料。调查结果用于评估参与者对塑料使用和处置的态度和行为。从一个典型的家庭中获得塑料废物的概况是很重要的。这将有助于制定更有针对性的战略来减少塑料污染。
Plastics are increasingly being used in consumer products due to its versatility in many applications. However, these plastics may contain inorganic elements that may be harmful to humans. To determine any potential health risk of plastics, it was important to characterize elemental composition of plastics and assess usage patterns. To investigate plastic usage in a typical Jamaican household and to characterize the inorganic elements in consumer plastics using XRF analyzer. About 200 questionnaires were distributed to households to determine the types and quantity of plastics. A total of 130 plastic samples from 7 categories were collected and measured for inorganic elements using handheld XRF. Household plastics were mainly used for storage and personal hygiene products. On average, 10% of plastics were recycled, while 30% were burned. Inorganic elements present in plastic samples were Cl > Ti > Ba > Fe > Zn > Sb > Cr > Br > Cu > V > Pb > As. Elemental concentrations varied based on the category of plastics. Green plastics had the highest concentrations of each type of elements. This study provided useful information on characterizing the different types of elements present in common household plastics. Results from the survey were used to assess participants’ attitude and behaviors towards plastics usage and disposal. It was important to obtain a profile of plastics waste from a typical household. This will allow for more targeted strategies to reduce plastics pollution.
