2017
This work describes a new protocol to assess the ecotoxicity of pollutants, including emerging contaminants such as nanomaterials, using the marine bacterium Vibrio anguillarum. This method allows for the determination of the LC50, or mortality, the concentration that causes a 50% decrease in bacteria culturability, after a 6 h exposure.

2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Environmental enrichment involves objects and practices that encourage natural behaviors, improve psychological well-being, and promote better welfare in laboratory rodents. Environmental enrichment should be tailored to the...

Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Alex Wassimi Viruses are a unique group of biological entities that infect both eukaryotic and prokaryotic organisms. They are obligate parasites that have no metabolic capacity, and in order to replicate, rely on host metabolism to produce viral parts that self-assemble inside host cells. Viruses are ultramicroscopic—too small to be viewed with the light microscope, visible only with...
FAQs
Source reduction addresses harmful releases before they require downstream treatment or disposal. In engineering, this principle can be combined with improved resource and energy efficiency to reduce environmental risks throughout a system. Treatment technologies remain important for emissions and wastewater, but preventing pollution at its origin can support cleaner manufacturing and reduce the burden placed on control infrastructure.
Measurement provides observations of environmental conditions, while modeling helps engineers analyze those conditions and evaluate how systems may respond to changing circumstances. Together, they support risk identification, performance assessment, and informed technology decisions. These tools are especially relevant when engineers must monitor air, water, soil, or ecosystem conditions and connect technical performance with public health and ecological outcomes.
Using resources and energy more efficiently can reduce the environmental pressures associated with engineering systems while supporting long-term sustainability. Efficiency is one component of a broader strategy that also includes source reduction, treatment, monitoring, and modeling. Its value extends across manufacturing, infrastructure, renewable-energy systems, and waste management because it links operational performance with conservation and resilience.
Environmental protection uses a layered strategy rather than depending exclusively on treatment after pollution has been generated. Engineers may first identify risks and reduce pollution at its source, then apply treatment to emissions or wastewater, and monitor resulting conditions. This combination addresses prevention, control, and verification, helping technical systems meet environmental standards while limiting harm to health and ecosystems.
A typical approach begins with identifying environmental risks and determining which air, water, soil, ecosystem, or health concerns require attention. Engineers then select source-reduction, efficiency, treatment, monitoring, or modeling measures appropriate to the system. Performance is evaluated through measurement, and technologies may be adapted as conditions change or environmental standards require continued improvement.
Applications include cleaner manufacturing, water and wastewater infrastructure, renewable-energy systems, waste management, and contaminated-site remediation. Each area presents different environmental risks and technical requirements, yet the same engineering priorities remain relevant: reduce pollution, conserve resources, treat harmful releases, and evaluate conditions through monitoring. This broad application makes environmental protection a cross-cutting concern rather than a single technology.
Monitoring and modeling allow engineers to recognize changing environmental conditions and assess whether existing technologies continue to perform appropriately. When conditions or ecological requirements shift, engineers can adapt system designs and management approaches rather than treating current performance as permanent. This responsiveness connects environmental standards with ecosystem resilience, resource conservation, and the long-term protection of human health.
