  • Arsenic in Drinking Water: What You Need to Know
    Arsenic in drinking water: what you need to know Why should I be concerned about arsenic in my drinking water? In Arizona, groundwater can contain arsenic that comes from natural sources, such as rocks and soils, and from human activities such as mining. Short-term exposure to very high doses of arsenic can cause poisoning. Long-term exposure to small doses has been linked to skin changes, cardiovascular effects, and cancer. Whether you are affected depends on how much arsenic you are exposed to and for how long, as well as your sensitivity to arsenic. What level of arsenic in my drinking water is considered safe? The United States Environmental Protection Agency has set the arsenic standard for drinking water at 10 parts per billion (ppb) to protect consumers served by public water systems from the effects of long-term, chronic exposure to arsenic. 10 ppb is roughly equal to 5 teaspoons of ink in an Olympic-sized swimming pool. Read below to learn more about testing and treating your water to reach 10 ppb arsenic or less. How can I learn what level of arsenic is in Arsenic is colorless and tasteless, my drinking water? so you cannot know it is there If you receive water from a municipal or privately-owned unless you test for it. water company, they are required to test your water for arsenic. You should receive an annual water quality report from your water supplier by July 1st of each year. If you drink bottled water, bottled water companies are not required to report results of any water quality testing.

Esse método é baseado na sorção do tensoativo aniônico (AS−), dodecilssulfato de sódio (SDS), sobre a superfície de γ-alumina, + enquanto um cartucho C18 é utilizado para a pré-concentração dos tensoativos catiônicos (CS ). O método espectrofotométrico, utilizado para a determinação dos tensoativos catiônicos, baseia-se na competição entre o corante catiônico, azul de metileno (MB+), e o CS+, para associação e formação do complexo SDS. O íon complexo formado (MB+) pode ser quantitativamente substituído pelo CS+, levando a um aumento da absorvância medida em 662 nm. Foram estabelecidas ótimas condições experimentais para a separação, pré-concentração e determinação dos tensoativos catiônicos. Sob essas condições otimizadas, realizou-se a pré-concentração (2×) e os resultados mostraram que a determinação do CPC, DTAB e CTAB poderia ser realizada nas faixas de concentração de 1×10-5-2×10-4, 4×10-5-5×10-4 and 5×10-5-5×10-4 mol L-1, respectivamente.

  • Minerals in Your Home Activity Book Minerals in Your Home Activity Book
    Minerals In Your Home Activity Book Minerals in Your Home Activity Book Written by Ann-Thérèse Brace, Sheila Stenzel, and Andreea Suceveanu Illustrated by Heather Brown Minerals in Your Home is produced by MineralsEd. © 2017 MineralsEd (Mineral Resources Education Program of BC) 900-808 West Hastings St., Vancouver, BC V6C 2X4 Canada Tel. (604) 682-5477 | Fax (604) 681-5305 | Website: www.MineralsEd.ca Introduction As you look around your home, it is important to think of the many things that you have and what are they made from. It’s simple - everything is made from Earth’s natural resources: rocks, soil, plants, animals, and water. They can be used in their natural state, or processed, refined and manufactured by people into other useable things. The resources that grow and can be replaced when they die or are harvested, like plants and animals, are called renewable resources. Those that cannot be regrown and replaced, like rocks, soil and water, are called non-renewable resources. All natural resources are valuable and we must use them conservatively. Mineral resources are natural Earth materials that must be mined from the ground. We use them every day, and they are non- renewable. Some are changed very little before they are used, like the rock granite for example, that is commonly used to make kitchen countertops or tombstones. Other mineral resources, like those that contain useful metals, must be processed to extract the metal ingredient. The metal is then manufactured into different parts of a product, like a toaster or a smartphone. Whether you are practicing violin in your room, eating a meal in the kitchen, watching TV in the living room or brushing your teeth in the bathroom, your daily activities use things that come from mineral resources.
