概括

在泰国,暴露于颗粒物 (PM) 对健康构成重大风险,特别是在冬季对成年人来说. 迫切需要空气质量管理,以减轻所有年龄组的这些风险.

科学领域:

环境健康环境健康
空气质量科学空气质量科学
公共卫生风险评估公共卫生风险评估

背景情况:

在快速城市化的东南亚,暴露于颗粒物 (PM) 给健康带来了相当大的风险.
在该地区,综合气象因素和PM的特定年龄健康影响的综合研究是有限的.

研究的目的:

为了评估PM2.5和PM10度的时空变化.
评估泰国曼谷,南塔布里和萨穆特普拉肯的相关非致癌健康风险.
分析儿童,成人和老年人的特定年龄的健康风险.

主要方法:

使用了五年 (2020-2024) 的每日PM数据和气象变量.
采用通用添加模型 (GAM) 来分析污染模式.
使用危险系数 (HQ) 和危险指数 (HI) 评估不同年龄人口的健康风险.

主要成果:

冬季呈现了最高的PM度 (PM2.5: 32.4-33.4 μg/m3; PM10: 56.6-61.7 μg/m3) 的地区.
所有危险指数 (HI) 值都超过了安全值 (>1),成年人面临的风险最高 (冬季HI:9.05-9.28).
观察到健康风险的地理异质性,集中在曼谷的城市核心和萨穆特普拉肯的工业区.

结论:

在所有人口群体和各省份发现,对PM暴露的健康风险始终较高.
鉴定出明显的季节性变化,特别是在冬季,由气象因素驱动.
调查结果强调需要有针对性的空气质量管理战略,特别是在冬季.

Sampling Plans

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
