摘要

生物过滤器广泛用于处理恶臭气体。了解生物过滤器在实际应用中的生物安全性需要对其生物气溶胶排放特性进行全面调查。在这项研究中，从三个全尺寸生物过滤器的进口和出口捕获的生物气溶胶以及包装材料微生物组进行了为期12个月的研究。对其特征、大小分布及来源进行了调查分析。值得注意的是，超过96%的生物气溶胶来自进口空气而不是包装材料。全尺寸的生物过滤器不仅减少了5-17%的细菌排放，而且降低了潜在的致病性。虽然生物过滤器有效地减少了生物气溶胶的排放，但仍然存在主要来自入口空气的潜在致病性。这项研究强调了在实际应用中评估与生物气溶胶相关的风险时考虑上游过程的重要性。

Do full-scale gas-phase biofilters reduce or increase bioaerosol emissions?

Biofilters are widely utilized for treating odorous gases. Understanding the biosafety of biofilters in real-world applications necessitates a comprehensive investigation into their bioaerosol emission characteristics. In this study, bioaerosols captured from the inlet and outlet, along with packing material microbiome were investigated over a 12-month period from three full-scale biofilters. Their characteristics, size distribution, and sources were investigated and analyzed. Notably, over 96% of the bioaerosols originated from the inlet air rather than from the packing materials. Full-scale biofilters not only reduced bacterial emissions by 5-17% but also lowered the potential pathogenicity. Although biofilters effectively diminished bioaerosol emissions, there are still potential pathogenicity primarily originated from the inlet air. This study emphasizes the significance of considering upstream processes when evaluating the risks associated with bioaerosols in real-world applications.

期刊介绍： The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
