April 25, 2018 - Properties, sources and uses of the element chlorine.

They say scent is the sense with the strongest ties to memory. The smell of chlorine reminds me of swimming lessons at the YMCA. I remember the taste of pennies, my curls drying brittle on the car ride home and the number one rule when swimming: do NOT open your eyes underwater.

The presence of different pollutants in recycled plastics is reviewed in this article. The desirable circular economy of plastics should be linked to the availability of clean recycled plastics with a non-significant and small to nil amount of substances of concern.

Polycyclic aromatic compounds (PAH) are a very large number of naturally occurring and man-made chemicals. The pure compounds are white or yellowish crystalline solids. They are insoluble in water but dissolve readily in fats and oils. Well-known PAHs are the compounds benzo[a]pyrene, fluoranthene, ...

Polycyclic aromatic hydrocarbons (PAHs) are common pollutants in water and have been reported to cause severe health effects in humans as well as the ecosystem. This study examined the concentrations of polycyclic aromatic hydrocarbons and estimated ...

December 16, 2020 - We’ve always mentioned that to maximize your pool chlorine’s effectivity, your pool’s pH levels must be on point. In this blog post, we’ll be going over the relationship of pool chlorine with the pH levels to find out WHY it’s needed to maintain proper pH levels for your pool.

May 3, 2018 - The importance of maintaining proper pH balance cannot be overstated. pH levels in swimming pools effect everything from swimmer comfort, longevity of pool surfaces and equipment, water clarity and more. One of the most overlooked problems associated with pH that is not properly balanced is ...

Chlorine gas is a toxic respiratory irritant that is considered a chemical threat agent because of the potential for release in industrial accidents or terrorist attacks. Chlorine inhalation damages the respiratory tract, including the airways and ...

Polycyclic aromatic hydrocarbons (PAHs) are emitted into the Canadian environment from both natural and anthropogenic sources. Forest fires, which release approximately 2000 tonnes of PAHs per year, are the single most important natural source of PAHs in Canada.

Polycyclic aromatic hydrocarbons (PAHs) are a class of the most common and widespread contaminants. The accumulation of PAHs has made a certain impact on the environment and is seriously threatening human health. Numerous general analytical methods suitable ...

On this page Overview Health effects Environmental effects Sources of emissions References Description Polycyclic aromatic hydrocarbons are formed by the incomplete combustion of coal, oil, petrol, wood, tobacco, charbroiled meats, garbage, or other organic materials. Most of them have no known use.

Pulmonary arterial hypertension (PAH) is a lethal disease. In resource‐limited countries PAH outcomes are worse because therapy costs are prohibitive. To improve global outcomes, noninvasive and widely available biomarkers that identify high‐risk ...

Chlorine is a contact irritant in both humans and animals, and the respiratory tract is the primary initial target organ, with higher exposures affecting multiple internal organs. Very little chlorine gas exists in the environment due to its high reactivity and degradation by sunlight (Hov, 1985).
