Air sanitization & purification People face many health risks from indoor pollution caused by: normal household activities such as cooking, washing laundry, cleaning, smoking, painting, etc. , and smoking odors, mold and mildew, and volatile organic compounds that slowly evaporate from modern plastics and glues used in building and furnituremaking materials. These pollution causes anxiety, allergic reactions, dizziness, dry cough, eye nose throat irritation, fatigue, fever, headaches, nausea, sneezing, sinus problems. Being exposed to environmental pollution in our living environments has varying degrees of risk that are hazardous. Ozone is both a strong oxidizing agent as well as a strong disinfectant. Because of this, both benefits (oxidation and disinfection) can be achieved during the single step of ozonation. Ozone is an effective and simple solution to achieve clean and healthy indoor air quality. 2. Water sterilization & treatment Ozone is an unstable molecule which readily gives up one atom of oxygen providing a powerful oxidizing agent which is toxic to most waterborne organisms. It is a very strong, broad spectrum disinfectant that has already been widely used in Europe for many years, both to treat water and disease (in particular cancer). Ozone is the ONLY oxidizer that can meet drinking water standards by eliminating such contaminants as cryptosporidium. It is also an effective method to inactivate harmful protozoa that form cysts. It also works well against almost all other pathogens. Some of the advantages of ozone include the production of fewer dangerous by-products and the absence of taste and odor problems. Another advantage of ozone is that it leaves no residual disinfectant in water. Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in France. The FDA has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods and the sanitation of municipal drinking water. 3. Vegetable, fruits & meat washing & sterilization Ozone can effectively kill most bacterial & viruses with more than 99% efficiency, and can also adequately eliminate residues of pesticides and chemical fertilizers on the surface of vegetables & fruits. Besides, ozone has advantages to decompose hormones & antibiotics in meat, poultry & fish, which can damage people’s health. Washing fruits and vegetables in ozonated water helps to reduce the pesticides and herbicide used by growers. It extends their shelf life and they will taste fresher. Some users state it helps in keeping the grease ants away. Others have said drinking ozonated water helps bad breath and relieves acid indigestion. Ozone Food Sanitation is FDA, USDA, EPA Approved: Ozone for food sanitation is recognized by agencies responsible for public health. The Environmental Protection Agency (EPA) approved the use of ozone as an antimicrobial in 1976. In 1982, the Food and Drug Administration (FDA) approved ozone as an antimicrobial additive for bottled water. And in 2001, the FDA and United States Department of Agriculture (USDA) approved the use of ozone as a non-thermal, antimicrobial direct food additive, including as part of a Certified Organic program. 4. Food storage & preservation Ozone is the best way to stop or slow down food spoilage, loss of quality, edibility or nutritional value and thus allow for longer food storage. It’s used to control the growth of unwanted biological organisms because it effectively kills viruses, bacteria, fungi, and parasites, including those causing food spoilage or human diseases. Ozone destroys microorganisms effectively by reacting with oxidizable cellular components and without leaving harmful residues behind. This makes the use of ozone food preservation. 5.

Healthy Waters 101: Water Quality Monitoring for Public Health
There are some who believe that we monitor water quality to protect the water itself, regulating to seemingly arbitrary water quality standards. Some believe that we monitor solely to protect endangered species and their habitat. For our own good, we mustn't lose sight of another type of habitat protection. Two cornerstones of environmental protection are the assurance of safe drinking water and clean water for fishing and swimming. What we're talking about is Healthy Waters for Healthy Humans! Around the turn of the 20th century, advances in environmental epidemiology and environmental engineering led to historic declines in US deaths from waterborne illnesses. One need only look at the death rate due to unsafe water, inadequate sanitation and poor hygiene in underdeveloped countries around the world today to appreciate the protection afforded us here. This webinar will discuss the public health significance of maintaining safe drinking water, healthy stocks of fish and shellfish, and clean water for recreation as well as for agricultural uses. This webinar will introduce water quality professionals to the agencies and associations of public health. This webinar will describe some of the less well-known water quality monitoring programs that interface with public health. Participants can expect to gain another tool to reach for when asked by their stakeholders "Why should I support water quality monitoring?" Healthy Waters for Healthy Humans!

Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

The amount of drinking water required varies. It depends on physical activity, age, health issues, and environmental conditions. Americans, on average, drink one litre of water a day and 95% drink less than three litres per day. For those who work in a hot climate, up to 16 litres a day may be required. Water is essential for life.Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to levels of toxins or suspended solids. Globally, by 2015, 89% of people had access to water from a source that is suitable for drinking - called improved water source. In Sub-Saharan Africa, access to potable water ranged from 40% to 80% of the population. Nearly 4.2 billion people worldwide had access to tap water, while another 2.4 billion had access to wells or public taps. The World Health Organization considers access to safe drinking-water a basic human right. About 1 to 2 billion people lack safe drinking water, a problem that causes 30,000 deaths each week. More people die from unsafe water than from war, U.N. Secretary-General Ban Ki-Moon said in 2010.
