Tastes, odors, and algal toxins in drinking water resources
Taste, odor, and appearance are the three key characteristics that consumers use to judge the quality and safety of water and aquaculture products. The global phenomenon of increased freshwater salinity may affect water quality. Technology is advancing capabilities to detect and treat tastings and odorants (T&O), algal/cyanobacteria cells, and toxins, as well as understanding sensory ...

Occurrence of toxic cyanobacteria and microcystin toxin in domestic water storage reservoirs, Egypt
Residents in many developing countries store treated drinking water in tanks or reservoirs because of intermittent and infrequent water supplies. Many studies have focused on bacterial contamination of domestic reservoir waters, the cyanobacterial and algal contamination is largely unexplored. Therefore, the present study investigates toxic cyanobacteria and their microcystin (MC) toxins in ...

Your Tap Water is More Toxic than you Think
At a Glance A new study proves that while adding chlorine to water has kept water clearer of diseases such as cholera and typhoid fever, it can leave behind toxic byproducts. These byproducts may have the potential to harm an individual’s long term health. At this point we don't even know all the byproducts left in the water from the current treatment methods. Your tap water might ...

Manufacture of a low-cost ceramic microporous filter for the elimination of microorganisms causing common diseases
Africa is one of the most water-scarce continents on earth and the lack of potable water is responsible for the death of approximately 4,900 children every day. An effective way of making sure that water is of good quality is by decontaminating it by means of a household ceramic water filter. The low-cost water filters suitable for the removal of suspended solids, pathogenic bacteria and other ...

What’s in Your Water
Water can be said to be the essence of life. Indeed, in many indigenous cultures, water is strongly linked to a people’s cultural identity. With the unfortunate news about the amount of lead found in Flint, Michigan’s public water system, perhaps more scrutiny and resources will be designated to improve and monitor this vital resource. But before you pour water into your glass, ...

Understanding the shifts in Lake Erie’s algae toxins
Lake Erie is hiding something beneath its green, murky surface, and it’s more complex than it seems. Recent findings from The Ohio State University throw light on this phenomenon. They reveal that during the early summer, we might be overestimating the harm of these toxins. But as we enjoy the last days of sun, these toxins might get stronger than we anticipate. ...

Vulnerability of Quebec drinking-water treatment plants to cyanotoxins in a climate change context
Cyanobacteria are a growing concern in the province of Quebec due to recent highly publicised bloom episodes. The health risk associated with the consumption of drinking water coming from contaminated sources was unknown. A study was undertaken to evaluate treatment plants' capacity to treat cyanotoxins below the maximum recommended concentrations of 1.5 μg/L microcystin-LR (MC-LR) and the ...

Satellites monitor algae toxin levels to ensure drinking water safety
Imagine that your daily routine is disrupted by a sudden ‘do not drink’ advisory for your local tap water because of elevated toxin levels. This scenario became a reality for cities like Toledo, OH in 2014, affecting more than 400,000 residents. The source? Microcystins - toxins produced by cyanobacteria, commonly referred to as blue-green algae. As climate change and human ...

Determining the fate of
Microcystis aeruginosa cells and microcystin toxins following chloraminationThe cyanobacterium Microcystis aeruginosa can produce potent toxins known as microcystins. While many studies have focussed on the chlorination of microcystin toxins, little work has been conducted with respect to the chloramination of the microcystins. In addition, no studies have been reported on the effect of chloramination on intact Microcystis cells. This study was conducted to determine the ...

Algal blooms: What are they?
Algal blooms are also known as marine blooms or water blooms, and are actually a sudden increase in the population of algae in water scenery. Algal blooms usually take place in freshwater, such as lakes and water reservoirs as well as in marine milieus. They can be easily identified by coloration of the water ensuing from the high density of pigmented cells. Though many types of algae can form ...

Reducing the Environmental Impact of Cows` Waste
No disrespect to cows, but they produce a lot of gas. And while farmers may be unfazed by the smell, the gas is methane, one of the most potent greenhouse gases. Across the globe, livestock spew 14.5 percent of all greenhouse gases (methane, carbon dioxide, nitrous oxide and fluorinated gases) released in the environment, and over half that comes specifically from cows, according to a United ...

Impacts of Climate Change on the Occurrence of Harmful Algal Blooms
Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...
