Which of the following can be classified under environmental health?

The management of industrial waste is a key component of environmental health because it directly impacts the environment and public health. Proper handling, treatment, and disposal of industrial waste are critical to preventing contamination of air, water, and soil, which can lead to serious health issues for the community and disruption of local ecosystems.

In environmental health, there is a focus on how waste management practices can affect human health and the environment. For example, if hazardous industrial waste is not managed correctly, it can lead to pollution that may cause respiratory problems, waterborne diseases, and various other health issues. Therefore, managing industrial waste ensures that health risks are minimized and the environment is protected, which falls squarely under the scope of environmental health.

The other options, although related to health, do not directly pertain specifically to the environmental health field or emphasize how environmental practices can influence human health as distinctly. The development of pharmaceuticals largely focuses on medical advancements rather than environmental impacts; the study of ecosystem balance, while critical to ecological science, does not directly address human health implications; and the analysis of community lifestyle choices mainly concerns public health and behavioral sciences rather than environmental health specifically.
