Wastewater Spawned Infectious Disease
Published in Frank R. Spellman, Fundamentals of Wastewater-Based Epidemiology, 2021
Nitrogen and phosphorus are the primary causes of cultural eutrophication (i.e., nutrient enrichment due to human activities) in surface waters. The most recognizable manifestations of this eutrophication are algal blooms that occur during the summer. Chronic symptoms of over-enrichment include low dissolved oxygen, fish kills, murky water, and depletion of desirable flora and fauna. In addition, the increase in algae and turbidity increases the need to chlorinate drinking water, which, in turn, leads to higher levels of disinfection by-products that have been shown to increase the risk of cancer (USEPA, 2007c). Excessive amounts of nutrients can also stimulate the activity of microbes, such as Pfisteria, which may be harmful to human health (USEPA, 2001d).

Substances such as minerals, nutrients, proteins, and unsaturated fats are called as built-up or customary supplements. Most vegetables, wholegrain oats, dairy items, and foods grown from the ground items, for example, meat are wellsprings of nutrient. These help in treatment of heart infections, stroke, waterfalls, osteoporosis, diabetes, and malignancy. Minerals found in plant, creature, and dairy items are helpful in treatment of issues related to bones, iron deficiency, teeth-related problems, and muscle issues; they help improve nerve motivations and heart beats. Salmon fish contains unsaturated fat, for example, omega-3 polyunsaturated unsaturated fats and, therefore, is considered a great controller of the irritation, maintains mind capacity, and declines cholesterol statement in a human body.
Water Pollution
Published in Frank R. Spellman, The Science of Water, 2020
Nutrients are organic and inorganic substances that provide food for microorganisms such as bacteria, fungi, and algae. Nutrients are supplemented by the discharge of sewage. The bacteria, fungi, and algae are consumed by the higher trophic levels in the community. Each stream, due to a limited amount of dissolved oxygen (DO), has a limited capacity for aerobic decomposition of organic matter without becoming anaerobic. If the organic load received is above that capacity, the stream becomes unfit for normal aquatic life and it is not able to support organisms sensitive to oxygen depletion (Mason, 1990; Spellman, 1996).

The importance of diet and nutrition to military readiness and performance has been recognized for centuries. Nutrients sustain health, protect against illness, and promote physical and cognitive resilience, performance and recovery. Irrespective of the food consumed, simply eating a meal can promote comradery and psychological well-being. As such, diet and nutrition are critical components of holistic approaches to maintaining healthy, ready and capable military forces. This concept is reflected in the increasingly inter-disciplinary nature of military nutrition research that explores topics ranging from manufacturing practices influencing ration composition and nutrient delivery, to the individual and environmental factors impacting nutrient requirements, dietary choices and nutrient metabolism. Within this spectrum, emphasis is often placed on the broad topics of: (1) determining operational nutrition requirements in all environments, (2) characterizing nutritional practices of military personnel relative to the required (role/environment) standards, and (3) developing strategies for improving nutrient delivery and individual choices.
