Kill Coho Salmon

“Mystery Compound Found to Kill Coho Salmon”, an article by Christopher Dunagan, emphasizes the negative impact of stormwater runoff on different types of fish in the river, specifically coho salmon. It’s proven by scientists that polluted stormwater runoff contains pollutants that kill coho salmon. Pre-spawn mortality in female coho salmon was noticed in rivers when high numbers died before giving birth, especially during times right after a rush of fresh stormwater. Scientists concluded that toxic chemicals were the problem after every other possibility got ruled out. Higher levels of metals were thought to be the cause but evidence proved that theory to be wrong. Salmon embryos interacting with this polluted water leads to brain bleeding,

...MINING AND WATER POLLUTION Water is essential to life on our planet. A prerequisite of sustainable development must be to ensure uncontaminated streams, rivers, lakes and oceans. There is growing public concern about the condition of fresh water in Canada. Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend. Water has been called “mining’s most common casualty” (James Lyon, interview, Mineral Policy Center, Washington DC). There is growing awareness of the environmental legacy of mining activities that have been undertaken with little concern for the environment. The price we have paid for our everyday use of minerals has sometimes been very high. Mining by its nature consumes, diverts and can seriously pollute water resources. Negative Impacts While there have been improvements to mining practices in recent years, significant environmental risks remain. Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment, and disturbance of water during mine construction. Water pollution from mine waste rock and tailings may need to be managed for decades, if not centuries, after closure. These impacts depend on a variety of factors, such as the sensitivity of local terrain, the composition of...

Dinoflagellate Algae

...Negative impacts of Dinoflagellate algae: economic, ecologic, and human health hazards ABSTRACT Increasing pollution both atmospheric and oceanic are encouraging algal growth and increasing the frequency and geographic range of high density dinoflagellate blooms. Public health and economic impacts, as well as negative ecological effects of the aquatic environment are increasing the scientific research done on toxic dinoflagellate species. Contaminated bivalves are causing paralytic shellfish poisoning (PSP) and diarrhetic shellfish poisoning in humans (DSP); with the number of cases increasing steadily in the last 40 years. Toxins released by certain species of the phylum dinoflagellate are the cause of this spreading contamination. Algal bloom locations are dictated by water currents and synaptic weather patterns, and their movement makes it difficult to pinpoint the origin of these blooms. Measuring the level of toxins in shellfish is currently the best way to chart the growing density of these blooms, and to prove the masses of algae are of growing concern. In this review the negative impact dinoflagellate algal blooms are having on aquaculture, human health hazards, and reasons for the increasing frequencies/densities of blooms will be covered; additional information on the shortcomings of incomplete scientific data complied on algal blooms and why scientific research is now being sought after will be reviewed. BACKGROUND Few species of phytoplankton produce...

...INTRODUCTION                           Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food.                         A soil pollutant is any factor which deteriorates the quality, texture and mineral content of the soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse effect on plant growth.                 The introduction of substances, biological organisms, or energy into the soil, resulting in a change of the soil quality, which is likely to affect the normal use of the soil or endangering public health and the living environment. Soil contaminants are spilled onto the surface through many different activities. Most of these are the result of accidents involving the vehicles that are transporting waste material from site of origin to a disposal site.                         Soil pollution is particularly dangerous for the environment and our health because soil, either in the mountains or in the plains, contains the largest part of the water we drink and produces all the food we need. There are many types of soil pollution...

Bad Bug Book

...Bad Bug Book   Handbook of Foodborne Pathogenic Microorganisms and Natural Toxins                                              Introduction  Food safety is a complex issue that has an impact on all segments of society, from the general public to government, industry, and academia. The second edition of the Bad Bug Book, published by the Center for Food Safety and Applied Nutrition, of the Food and Drug Administration (FDA), U.S. Department of Health and Human Services, provides current information about the major known agents that cause foodborne illness. The information provided in this handbook is abbreviated and general in nature, and is intended for practical use. It is not intended to be a comprehensive scientific or clinical reference. Under the laws administered by FDA, a food is adulterated if it contains (1) a poisonous or otherwise harmful substance that is not an inherent natural constituent of the food itself, in an amount that poses a reasonable possibility of injury to health, or (2) a substance that is an inherent natural constituent of the food itself; is not the result of environmental, agricultural, industrial, or other contamination; and is present in an amount that ordinarily renders the food injurious to health. The first includes, for example, a toxin produced by a fungus that has contaminated a food, or a pathogenic bacterium or virus, if the amount present in the food may be injurious to health. An example of the second...

If I Stay

...FOR NICK Finally . . . Always 7:09 A.M. Everyone thinks it was because of the snow. And in a way, I suppose that’s true. I wake up this morning to a thin blanket of white covering our front lawn. It isn’t even an inch, but in this part of Oregon a slight dusting brings everything to a standstill as the one snowplow in the county gets busy clearing the roads. It is wet water that drops from the sky—and drops and drops and drops—not the frozen kind. It is enough snow to cancel school. My little brother, Teddy, lets out a war whoop when Mom’s AM radio announces the closures. “Snow day!” he bellows. “Dad, let’s go make a snowman.” My dad smiles and taps on his pipe. He started smoking one recently as part of this whole 1950s, Father Knows Best retro kick he is on. He also wears bow ties. I am never quite clear on whether all this is sartorial or sardonic—Dad’s way of announcing that he used to be a punker but is now a middle-school English teacher, or if becoming a teacher has actually turned my dad into this genuine throwback. But I like the smell of the pipe tobacco. It is sweet and smoky, and reminds me of winters and woodstoves. “You can make a valiant try,” Dad tells Teddy. “But it’s hardly sticking to the roads. Maybe you should consider a snow amoeba.” I can tell Dad is happy. Barely an inch of snow means that all the schools in the county are closed, including my high school and the middle school where Dad works, so it’s an unexpected day off for him, too. My mother, who...
