Do you struggle with understanding how to respond to the human health implications of environmental contamination? Dr Alex Stewart, a medical board member of SEGH, is an editor and contributing author of a new text covering the public health response (known as health protection) to such situations, as well as to emergencies and incidents of infectious diseases.
  • The text comprehensively covers health protection with relevance to practitioners working in every area of the field, whether in public health or environmental sciences or other professions.
  • There are detailed descriptions with practical examples of how to respond to rapidly changing emergencies and complex and chronic environmental hazards and situations.
  • Guidance is provided on the practice of health protection through case studies and scenarios; each one is a realistic insight into health protection situations.
  • Uniquely, the book includes quick reference checklists (SIMCARDs) which provide a hands-on way of dealing with and providing public health advice on different health protection situations (acute & chronic), through concise, practically-focussed crib sheets of essential information and tasks covering a broad range of health protection topics: ideal for use in the field or even exam revision.
  • The textbook is relevant for non-specialists such as environmental scientists, as well as public health and health protection specialists. For non-specialists, and those without a medical background, the first four chapters give the grounding necessary to use the remainder of the book in a practical way.
Health Protection: Principles and practice is the first textbook in health protection to address all three domains within the field — environmental public health; emergency preparedness, resilience and response (EPRR); and communicable disease control — in a comprehensive and integrated manner. Written by leading practitioners in the field, the book is rooted in a practice-led, all-hazards approach, which allows for easy real-world application of the topics discussed.
The chapters are arranged in six sections:
1 In-depth introduction to the principles of health protection
Case studies and scenarios to describe common and important issues in the practice of health protection:
2 Infectious disease
3 Emergency preparedness, resilience and response
4 Environmental public health
5 Health protection tools (epidemiology, statistics, infection control, immunisation, disease surveillance, audit and service improvement)
6 Evidence about new and emerging issues, including environmental issues and disasters.
The book includes more than 100 checklists (SIMCARDs), covering the three domains of health protection. Written from first-hand experience of managing such issues, these provide practical, stand-alone quick reference guides for use in many, if not most, situations, likely or unlikely, that can and will be faced in this continually evolving field.
Both the topical content of Health Protection: Principles and practice, and the clearly described health protection principles the book provides, make it a highly relevant resource for professionals within and without public health and health protection.

  • Membrane fouling control by Ca 2+ during coagulation–ultrafiltration process for algal-rich water treatment 2019-04-16


    Seasonal algal bloom, a water supply issue worldwide, can be efficiently solved by membrane technology. However, membranes typically suffer from serious fouling, which hinders the wide application of this technology. In this study, the feasibility of adding Ca2+ to control membrane fouling in coagulation–membrane treatment of algal-rich water was investigated. According to the results obtained, the normalized membrane flux decreased by a lower extent upon increasing the concentration of Ca2+ from 0 to 10 mmol/L. Simultaneously, the floc particle size increased significantly with the concentration of Ca2+, which leads to a lower hydraulic resistance. The coagulation performance is also enhanced with the concentration of Ca2+, inducing a slight osmotic pressure-induced resistance. The formation of Ca2+ coagulation flocs resulted in a looser, thin, and permeable cake layer on the membrane surface. This cake layer rejected organic pollutants and could be easily removed by physical and chemical cleaning treatments, as revealed by scanning electron microscopy images. The hydraulic irreversible membrane resistance was significantly reduced upon addition of Ca2+. All these findings suggest that the addition of Ca2+ may provide a simple-operation, cost-effective, and environmentally friendly technology for controlling membrane fouling during coagulation–membrane process for algal-rich water treatment.

  • Evaluation of the raw water quality: physicochemical and toxicological approaches 2019-04-13


    Environmental degradation has increased, mainly as a result of anthropogenic effects arising from population, industrial and agricultural growth. Water pollution is a problem that affects health, safety and welfare of the whole biota which shares the same environment. In Goiânia and metropolitan region, the main water body is the Meia Ponte River that is used for the abstraction of water, disposal of treated wastewater and effluents. In addition, this river receives wastewater from urban and rural areas. The aim in this present study was to evaluate the quality of raw water by some physical, chemical and toxicological tests. The physicochemical results found high levels of turbidity, conductivity, aluminum, phosphorus and metal iron, manganese, copper and lithium when compared to the standards of the Brazilian legislation. The values found of toxicity demonstrated a high degree of cytotoxicity and genotoxicity. Therefore, it was concluded that the Meia Ponte River has been undergoing constant environmental degradation, causing the poor quality of its waters. Thus, measures for the prevention and recovery should be adopted for the maintenance of the Meia Ponte River.

  • Review of the nature of some geophagic materials and their potential health effects on pregnant women: some examples from Africa 2019-04-11


    The voluntary human consumption of soil known as geophagy is a global practice and deep-rooted in many African cultures. The nature of geophagic material varies widely from the types to the composition. Generally, clay and termite mound soils are the main materials consumed by geophagists. Several studies revealed that gestating women across the world consume more soil than other groups for numerous motives. These motivations are related to medicinal, cultural and nutrients supplementation. Although geophagy in pregnancy (GiP) is a universal dynamic habit, the highest prevalence has been reported in African countries such as Kenya, Ghana, Rwanda, Nigeria, Tanzania, and South Africa. Geophagy can be both beneficial and detrimental. Its health effects depend on the amount and composition of the ingested soils, which is subjective to the geology and soil formation processes. In most cases, the negative health effects concomitant with the practice of geophagy eclipse the positive effects. Therefore, knowledge about the nature of geophagic material and the health effects that might arise from their consumption is important.
