中文摘要：铅锌浮选厂在生产过程中产生大量颗粒物,污染工作环境.以某铅锌浮选厂为研究对象,对厂房内、外颗粒物浓度分布情况进行测试分析,并对其污染状态及健康影响进行深入研究.结果表明:粒径小于10 μm颗粒物其厂房内数量浓度高于厂房外,且数量浓度随粒径变小而增加,厂房内、外颗粒物的数量浓度比平均值大多大于 1.PM10、PM2.5 和PM1 的厂房内质量浓度显著高于厂房外,厂房内PM10、PM2.5分别超过一级标准 5.333 倍和 6.313 倍,超过二级标准 2.614 倍和2.134 倍.厂房内对厂房外颗粒物浓度有较大影响,颗粒物的分布和浓度也有所不同,环境因素对粉尘污染有较大影响.研究结果可为矿山环境颗粒物的有效控制提供数据参考价值.

外文摘要：During the production process in a lead-zinc flotation plant,a large amount of particulate matter is generated,polluting the working environment.This study takes a lead-zinc mine as an example and analyzes the distribution of particulate matter concentration inside and outside the flotation plant.The pollution status and its health impacts are thoroughly investigated.The results show that the quantity concentration of particulate matter smaller than 10 μm inside the average plant is higher than outside,with the quantity concentration increasing as particle size decreases.The average ratio of quantity concentration of particulate matter inside to outside the plant is generally greater than 1.The mass concentrations of PM10,PM2.5,and PM1 inside the plant are significantly higher than those outside,with PM10 and PM2.5 inside the plant exceeding the Grade 1 standard by 5.333 times and 6.313 times,respectively,and the Grade 2 standard by 2.614 times and 2.134 times.The concentration of particulate matter inside the plant significantly influences the concentration outside.The distribution and concentration of particulate matter vary,and environmental factors greatly impact dust pollution.The study's findings provide valuable data for effectively controlling particulate matter in mining environments.
