摘要

室内人工照明是家禽生产的一个重要方面。然而，人们对动态照明时间表对家禽舍中粉尘或颗粒物（PM）产生的影响知之甚少。在一个商业蛋鸡鸡舍进行了连续6个月的综合现场测量。每分钟采集粉尘（PM10）浓度、通风量、照明时间、母鸡活动等数据并进行分析。结果表明，光照时间的日变化对母鸡活动和室内粉尘浓度有显著影响。动态光照持续时间的逐渐增加与粉尘排放率的变化的比较表明，换羽后一个月的相关系数为0.802。在此期间，日扬尘排放量增加了12.5倍。研究认为，鸡舍内动态光照是影响蛋鸡活动和粉尘浓度格局的一个新因素。此外，它们可能会大幅增加粉尘的产生。

A new factor of dynamic lighting schedule on dust production in commercial laying hen house

Indoor artificial lighting is an essential aspect of poultry production. However, little is known about the impact of dynamic lighting schedules on the production of dust, or particulate matter (PM), in poultry houses. A comprehensive field measurement was conducted in a commercial laying hen house continuously for six months. Data on dust (PM₁₀) concentration, ventilation rate, lighting schedule, and hen activity were collected every minute and analyzed. Results showed that daily changes in the lighting schedule significantly impacted hen activity and indoor dust concentrations. A comparison of gradual increases in dynamic lighting durations and changes in dust emission rates revealed a high correlation coefficient of 0.802 during the post-molting period, which lasted about one month. During this period, daily dust emission rates increased by 12.5 times. The study concluded that dynamic lighting schedules in laying hen houses represent a new factor influencing diel hen activity and dust concentration patterns. Additionally, they could drastically increase dust production.

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
