Objective

To identify the main chemical occupational hazard factors and their exposure levels associated with condensate oil in natural gas exploitation, and to explore occupational health risk assessment methods for chemical hazards in this industry, so as to provide a basis for accurately preventing occupational hazards and protecting the health of occupational populations.

Methods

Based on occupational health surveys, condensate oil component analysis and continuous monitoring of chemical occupational hazards, the occupational health risks of condensate oil exposure in natural gas exploitation were assessed using the comprehensive index method, ICMM quantitative assessment method and occupational hazard risk index method.

Results

The main occupational hazard factors of condensate oil in natural gas exploitation were benzene, toluene, xylene, n-hexane and cyclohexane. Their time-weighted average concentrations (CTWA) ranged within 1%-50% of the occupational exposure limits (OELs). Among the 10 gas production well stations, only xylene concentration showed statistical significance (P<0.001), while concentrations of the other four chemical toxicants were generally consistent (P>0.05). Short-term exposure concentrations (CSTEL) of all five typical chemical toxicants were detected in the gas field water treatment station, with generally consistent concentrations (P>0.05). Analysis of occupational health risk levels showed that according to the comprehensive index method, benzene was rated as extremely high risk in both gas production stations and gas field water treatment stations, toluene, n-hexane and cyclohexane as high risk, and xylene as medium risk. According to the occupational hazard risk index method, benzene was moderate risk in the gas field water treatment station and mild risk in gas production stations, while all other factors were assessed as no risk. In the ICMM quantitative assessment method, only benzene in the gas field water treatment station was rated as intolerable risk, and all other factors were rated as tolerable risk. The Kruskal-Wallis test showed significant differences in the rating distributions among the three methods (P<0.05), indicating that different assessment systems varied in their ability to discriminate risk levels of hazardous factors.

Conclusion

Benzene, toluene, xylene, n-hexane and cyclohexane should be the key occupational hazards concerned in condensate oil exposure in the natural gas exploitation industry. The improved ICMM quantitative assessment is a suitable method for occupational health risk assessment of condensate oil in natural gas exploitation.

目的

明确天然气开采凝析油存在的主要化学职业病危害因素及其暴露水平，探究该行业化学有害因素职业健康风险评估方法，为精准预防职业病危害因素、保护职业人群健康提供依据。

方法

基于职业卫生调查、凝析油组分分析及职业病化学有害因素连续监测，采用综合指数法、ICMM定量评估法及职业危害风险指数法评估天然气开采凝析油暴露职业健康风险。

结果

天然气开采凝析油主要职业病危害因素为苯、甲苯、二甲苯、正己烷、环己烷，其时间加权浓度（CTWA）处于1%~50%OELs区间，10个采气井站中，仅有二甲苯的浓度水平存在统计学意义（P<0.001），其余4种化学毒物浓度均基本一致（P>0.05）；气田水处理站五种典型化学毒物短时间浓度（CSTEL）均有检出，且浓度基本一致（P>0.05）。职业健康风险等级分析，采气站与气田水处理站综合指数法风险，苯均为极高风险，甲苯、正己烷、环己烷为高风险，二甲苯为中等风险；职业危害风险指数法显示，气田水处理站苯为中度风险，采气站苯为轻度风险，其余均无风险；ICMM定量评估法中仅有气田水处理站苯的风险评级为不可容忍风险，其余均为可容忍风险；三种方法Kruskal-Wallis检验评级分布存在差异（P<0.05）。反映出不同评估体系在有害因素风险等级的判别能力上有所不同。

结论

天然气开采行业凝析油暴露应重点关注职业病危害因素为苯、甲苯、二甲苯、正己烷、环己烷，改良后的ICMM定量评估是天然气开采凝析油职业健康风险评估的适宜方法。

目的

明确天然气开采凝析油存在的主要化学职业病危害因素及其暴露水平，探究该行业化学有害因素职业健康风险评估方法，为精准预防职业病危害因素、保护职业人群健康提供依据。

方法

基于职业卫生调查、凝析油组分分析及职业病化学有害因素连续监测，采用综合指数法、ICMM定量评估法及职业危害风险指数法评估天然气开采凝析油暴露职业健康风险。

结果

天然气开采凝析油主要职业病危害因素为苯、甲苯、二甲苯、正己烷、环己烷，其时间加权浓度（CTWA）处于1%~50%OELs区间，10个采气井站中，仅有二甲苯的浓度水平存在统计学意义（P<0.001），其余4种化学毒物浓度均基本一致（P>0.05）；气田水处理站五种典型化学毒物短时间浓度（CSTEL）均有检出，且浓度基本一致（P>0.05）。职业健康风险等级分析，采气站与气田水处理站综合指数法风险，苯均为极高风险，甲苯、正己烷、环己烷为高风险，二甲苯为中等风险；职业危害风险指数法显示，气田水处理站苯为中度风险，采气站苯为轻度风险，其余均无风险；ICMM定量评估法中仅有气田水处理站苯的风险评级为不可容忍风险，其余均为可容忍风险；三种方法Kruskal-Wallis检验评级分布存在差异（P<0.05）。反映出不同评估体系在有害因素风险等级的判别能力上有所不同。

结论

天然气开采行业凝析油暴露应重点关注职业病危害因素为苯、甲苯、二甲苯、正己烷、环己烷，改良后的ICMM定量评估是天然气开采凝析油职业健康风险评估的适宜方法。

Objective

To identify the main chemical occupational hazard factors and their exposure levels associated with condensate oil in natural gas exploitation, and to explore occupational health risk assessment methods for chemical hazards in this industry, so as to provide a basis for accurately preventing occupational hazards and protecting the health of occupational populations.

Methods

Based on occupational health surveys, condensate oil component analysis and continuous monitoring of chemical occupational hazards, the occupational health risks of condensate oil exposure in natural gas exploitation were assessed using the comprehensive index method, ICMM quantitative assessment method and occupational hazard risk index method.

Results

The main occupational hazard factors of condensate oil in natural gas exploitation were benzene, toluene, xylene, n-hexane and cyclohexane. Their time-weighted average concentrations (CTWA) ranged within 1%-50% of the occupational exposure limits (OELs). Among the 10 gas production well stations, only xylene concentration showed statistical significance (P<0.001), while concentrations of the other four chemical toxicants were generally consistent (P>0.05). Short-term exposure concentrations (CSTEL) of all five typical chemical toxicants were detected in the gas field water treatment station, with generally consistent concentrations (P>0.05). Analysis of occupational health risk levels showed that according to the comprehensive index method, benzene was rated as extremely high risk in both gas production stations and gas field water treatment stations, toluene, n-hexane and cyclohexane as high risk, and xylene as medium risk. According to the occupational hazard risk index method, benzene was moderate risk in the gas field water treatment station and mild risk in gas production stations, while all other factors were assessed as no risk. In the ICMM quantitative assessment method, only benzene in the gas field water treatment station was rated as intolerable risk, and all other factors were rated as tolerable risk. The Kruskal-Wallis test showed significant differences in the rating distributions among the three methods (P<0.05), indicating that different assessment systems varied in their ability to discriminate risk levels of hazardous factors.

Conclusion

Benzene, toluene, xylene, n-hexane and cyclohexane should be the key occupational hazards concerned in condensate oil exposure in the natural gas exploitation industry. The improved ICMM quantitative assessment is a suitable method for occupational health risk assessment of condensate oil in natural gas exploitation.

凝析油（Gas Condensate，GC）是一种特殊的轻质油，具有原始地层温度下为气态和地面常压下凝结为液态的气液两相特征，其成分与原油成因有关，不同地区的凝析油成分不同[1]。我国中原和西南地区是凝析油主要储存地，四川盆地气藏油气较为丰富[2-3]。天然气开采过程中的凝析油为气藏油气凝析而成。研究显示，凝析油含芳香烃（如苯、甲苯、二甲苯）、烷烃（如正己烷）等多种化学有害因素，这些有害因素大多为职业病高风险因素[4-6]。作业过程中因凝析油气液两相的特征，上述有害因素可通过呼吸道、皮肤等途径进入体内。团队前期调研发现，某天然气开采单位凝析油暴露职工有1例疑似职业性慢性苯中毒，其苯的暴露浓度达到苯职业接触限值（OELs）的20%～60%。天然气开采过程中凝析油暴露及其含凝析油污水处理环节作业者的职业有害因素防护形势严峻[7]。目前，国内外针对石油原油、成品油的职业苯暴露及健康效应研究已较为系统[8]，针对凝析油暴露场景下关键危害因子的识别及适宜风险评估方法的研究尚属空白。职业健康风险与危害程度不明[9]，现有评估方法在此类复杂暴露情境中的适用性难以确定，给该行业从业人员的职业病防治与职业健康管理工作带来了挑战。本研究旨在以天然气开采的凝析油暴露为研究对象，根据工作场所连续性危害监测结果，采用综合指数法、职业危害风险指数法及ICMM 定量评估法三种风险评估方法，筛选适用于天然气开采行业凝析油暴露的风险评估方法，为该行业职业病防控与职业健康管理提供科学工具。
1　对象与方法
收起
1.1　对象
根据四川某天然气开采井站现状，结合工作场所职业性有害因素分析，按照15%的比例从64座含凝析油天然气开采井站中随机抽取10个井站和1个气田水集中处理站为研究对象。
1.2　方法
1.2.1　职业卫生调查
职业卫生技术服务人员进行职业卫生调查，包括场所布局、采气工艺、工程防护、个体防护及职业性有害因素接触情况。
1.2.2　职业卫生监测
凝析油原液组分分析采用广东省职业卫生技术质量控制中心技术指南GDOHTQC 001—2020的方法[10]，用W9N08标准谱库检索，相对保留时间RSD和峰面积RSD均小于10%、匹配因子均大于75%的化合物明确组分，报告限为0.1%，对3批次9个凝析油液体原液样品进行组分分析。典型化学毒物监测，由于采气站采用巡检作业模式，工作点位不固定、流动性强，故对采气工岗位采用个体采样，通过随机数表法抽取17名采气工佩戴采样设备。水处理站工艺流程集中、岗位固定，为减少对作业的影响，对水处理工岗位采用定点采样，在9个点位（回注水处理池、钻井液废水接收池、均质隔油池、高浓水池、脱氮水池、压滤机、压裂返排液接收池、300 m3罐、800 m3罐）分别设置采样点，并按照现行国家标准要求对采集样品进行分析[11-15]；采样频次为1次/月，连续6个月，主要设备：全二维气相色谱-飞行时间质谱联用仪（GC×GC-TOF MS）、全二维气相色谱-氢火焰离子化检测器（GC×GC-FID）。
1.2.3　统计学方法
采用Excel 2010建立数据库，SPSS 29.0软件包进行统计分析。正态分布数据采用（）描述，批次浓度比较采用方差分析。非正态分布数据采用中位数（M）、四分位间距（IQR）描述，风险评估方法比较采用非参数检验（Kruskal-Wallis检验），检验水准α=0.05。
1.2.4　职业健康风险评估
采用综合指数法、职业危害风险指数法、ICMM定量评估法：①综合指数法：风险指数。其中：HR为危害等级，ER为接触等级。风险等级：可忽略（R=1）；低风险（R=2）；中等风险（R=3）；高风险（R=4）；极高风险（R=5）[16]。②职业危害风险指数法：风险指数（R）=2健康效应等级×2暴露比值×作业条件等级，风险等级：R≤6为无危害；7~11为轻度危害；12~23为中度危害；24~80为高度危害；>80为极度危害[17]。③ICMM定量评估法：风险评级值（RR）=后果（C）×暴露概率（PrE）×暴露时间（PeE），风险等级：RR<20为可容忍风险；20~69为潜在风险；70~199为高风险；200~399为非常高风险；≥400为不可容忍风险[18]。因原模型暴露时间于4～8h时赋值困难，综合现场实际与行业专家咨询，调整了ICMM模型的赋值条件[19]，见表1。

含凝析油天然气开采主要包括采气和气田水处理两大部分，混合化学毒物的凝析油对劳动者存在健康危害。本研究首次阐明了苯、甲苯、二甲苯、正己烷、环己烷为凝析油五种典型化学毒物。研究表明，含凝析油天然气开采的采气井站和气田水处理站五种典型化学毒物均存在，不同岗位的暴露水平不同，气田水处理站苯暴露浓度最高，这与气田水处理场所含凝析油的污水较为集中，跑冒滴漏或敞开作业凝析油持续挥发有关[20]。提示，含凝析油天然气开采行业，除天然气开采固有职业病危害因素外，应重点关注凝析油挥发物职业防控，尤其是上述五种典型化学毒物。
职业健康风险评估在含凝析油天然气开采行业中应用较少。本研究的三种职业健康评估方法均一致识别苯是凝析油暴露的首要风险因素，与既往研究存在一定差异[6、21]，主要表现为文献中识别的主要风险因素包含硫化氢。然而本研究所涉油品中不含硫化氢成分。在排除这一地域性组分差异后，本研究识别出的核心风险因素与既往研究基本一致。方法在风险分级精度、场景区分能力和防控指导意义上存在差异。综合指数法：操作简便，但存在高估的可能。主要是因为是该方法危害等级过于依赖物质的固有毒性，而对工程防护措施、实际暴露时长等关键风险量化整合不足，导致其在复杂暴露场景下的分辨率和准确性受限[22-23]。职业危害风险指数法引入了作业条件等级，整合了暴露人数、接触时间及防护措施等多维信息，场景区分能力良好，能够实现岗位风险差异识别，适用于早期风险筛查与分级管理。改良的ICMM定量评估法综合性能表现最优，综合了精准识别气田水处理站的苯暴露为“不可容忍风险”和其他毒物及场所均为“可容忍风险”，依托纯定量计算规避人工主观赋权偏差，能将暴露概率和暴露时间因素与连续性监测数据链接，系统整合毒理阈值及加工作业场景通风、防护、作业频率等多维度指标，输出的风险值物理意义明确、定量精准且可溯源，能更全面表征凝析油相关职业健康的实际程度，且其健康后果的赋值能准确反映不同毒物的权重差异，符合“致癌物优先管理”的基本原则，能够客观揭示不同岗位间的风险差异，为制定差异化、精准化的工程控制、个体防护和管理措施提供了可靠的量化依据。本研究识别出水处理站苯暴露风险较高，建议重点加强该场所局部通风、密闭防护及个体防护等综合措施，并优化凝析油储存和转运环节的工程控制措施。
综上，本研究通过凝析油组分分析、连续监测及多种职业健康评估方法，系统阐明了了凝析油作业中应重点关注的化学毒物，并明确了不同职业健康风险评估方法在天然气开采凝析油暴露场景中的适用性，可为该行业职业健康管理的精准化和科学化提供科学依据。
但受研究区域及对象范围所限，凝析油组分特征与作业场景的代表性有待进一步提升；本研究主要针对 ICMM 法中暴露概率与暴露时间赋值进行优化，对多种化学毒物联合作用的探讨尚不充分，可能在一定程度上低估了劳动者的综合健康风险。
未来研究可扩大研究样本量与监测周期，纳入气象条件、作业方式等关键影响因素，并深入构建多毒物联合暴露风险评估模型，从而更全面、真实地反映凝析油暴露所致的职业健康风险。
