Lead Contamination In Oakland
Lead contamination in Oakland represents a serious and persistent public health threat. Lead contamination in modern Oakland comes from three primary sources: remnants from previous industry, deposits from leaded gasoline, and paint chips from leaded paints. Significant portions of the City of Oakland, California have soil lead levels far in excess of 400 ppm, the level at which the US EPA suggests remedial action be taken, and far higher than 80 ppm, the level at which California’s Office of Environmental Health Hazard Assessment suggests action should be taken. Not all areas of Oakland are affected equally: West Oakland's contamination is especially severe, particularly near the former Oakland Army Base, and many of Oakland's poorer neighborhoods also suffer disproportionately (since residents often lack the socioeconomic resources to remediate their lawns, or even to repaint their houses). High blood levels of lead have been linked to a lead poisoning, wide variety of health pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Contamination
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. The brain is the most sensitive. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet. It causes almost 10% of intellectual disability of otherwise unknown cause and can result in behavioral problems. Some of the effects are permanent. In severe cases, anemia, seizures, coma, or death may occur. Exposure to lead can occur by contaminated air, water, dust, food, or consumer products. Lead poisoning poses a significantly increased risk to children as they are far more likely to ingest lead indirectly by chewing on toys or other objects that are coated in lead paint. The amount of lead that can be absorbed by children is also higher than that of adults. Exposure at work is a common cause of lead poisoning in adults with certain occupations at particular risk. Diagnosis is typically by m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lead Poisoning Incidents
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Justice In The United States
Environmental racism is a form of institutional racism, in which people of colour experience environmental harms, such as pollution and the effects of natural disasters, at a disproportionately high rate. Some scholars have coined environmental racism as the "New Jim Crow". Like Jim Crow laws, environmental racism systematically disenfranchises black people. It causes devastating impacts on the physical and mental health of African Americans, and creates disparities in many different spheres of life, such as transportation, housing, infrastructure, health, and economic opportunity. Epidemiologists Joel Kaufman and Anjum Hajat argue that, "discriminatory policies and practices that constitute environmental racism have disproportionately burdened communities of color, specifically African-Americans, Native Americans, Asian Americans and Pacific Islanders, and Hispanic populations." Communities of color are more likely to be located next to pollution sources, such as landfills, pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Poisoning Epidemics
Lead poisoning epidemics refer to instances of mass lead poisoning, and usually occur unintentionally in low income countries. Lead recycling is a common cause of a poisoning epidemic, and it is commonplace and sometimes the only means of providing sustenance in poorer countries. The lack of immediate and obvious health effects often result in people taking excessive risks and few precautions when handling lead. These events can also cause disproportionate childhood fatalities, when levels of toxins become fatal in lower concentrations in children compared with adults. Notable poisoning events This list does not include episodes of fewer that 100 people affected, nor does it include individual lead paint poisoning cases, nor those caused by eating contaminated food or water. The cases below are discrete events of mass lead poisonings. *number tested high is defined as a blood lead level greater than or equal to 10 micrograms per deciliter whole blood (ug/dl) See also * List of ...

Exide Lead Contamination
Exide is one of the world's largest producers, distributors and recyclers of lead-acid batteries. Lead-acid batteries are used in automobiles, golf carts, fork-lifts, electric cars and motorcycles. They are recycled by grinding them open, neutralizing the sulfuric acid, and separating the polymers from the lead and copper. In the US, 97 percent of the lead from car batteries is recycled - which is the highest recycling rate for any commodity. Most states require stores to take back old batteries. Since 2010, operations at seven Exide lead-acid battery plants have been linked to ambient heavy metal levels that posed a health risk to the environment and thousands of residents in neighborhoods surrounding the Exide plants. Exide has been found to be a significant source of lead emissions and/or contamination in Crescentville, Philadelphia (1920 - 1978); Los Angeles County; Frisco, Texas; Muncie, Indiana; Salina, Kansas; Bristol, Tennessee; Reading, Pennsylvania; and Forest City, ...

1989 Loma Prieta Earthquake
The 1989 Loma Prieta earthquake occurred on California's Central Coast on October 17 at local time. The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. With an magnitude of 6.9 and a maximum Modified Mercalli intensity of IX (''Violent''), the shock was responsible for 63 deaths and 3,757 injuries. The Loma Prieta segment of the San Andreas Fault System had been relatively inactive since the 1906 San Francisco earthquake (to the degree that it was designated a seismic gap) until two moderate foreshocks occurred in June 1988 and again in August 1989. Damage was heavy in Santa Cruz County and less so to the south in Monterey County, but effects extended well to the north into the San Francisco Bay Area, both on the San Francisco Peninsula and across the bay in Oakland.

Cypress Street Viaduct
The Cypress Street Viaduct, often referred to as the Cypress Structure or the Cypress Freeway, was a 1.6-mile-long (2.5 km), raised two-deck, multi-lane (four lanes per tier) freeway constructed of reinforced concrete that was originally part of the Nimitz Freeway ( State Route 17, and later, Interstate 880) in Oakland, California. It replaced an earlier single-deck viaduct constructed in the 1930s as one of the approaches to the San Francisco–Oakland Bay Bridge. It was located along Cypress Street between 7th Street and Interstate 80 in the West Oakland neighborhood. It officially opened to traffic on June 11, 1957, and was in use until October 17, 1989. At approximately 5:04 p.m. that day, a magnitude 6.9 earthquake struck the Bay Area, resulting in a large portion of the freeway's upper deck collapsing onto the lower deck. The collapse killed 42 people and resulted in the subsequent demolition of the structure. The Cypress Freeway Memorial Park is located in Oaklan ...

Pyromorphite
Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5( P O4)3 Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. Crystals are common, and have the form of a hexagonal prism terminated by the basal planes, sometimes combined with narrow faces of a hexagonal pyramid. Crystals with a barrel-like curvature are not uncommon. Globular and reniform masses are also found. It is part of a series with two other minerals: mimetite (Pb5( AsO4)3Cl) and vanadinite (Pb5( VO4)3Cl), the resemblance in external characters is so close that, as a rule, it is only possible to distinguish between them by chemical tests. They were formerly confused under the names green lead ore and brown lead ore (''German: Grünbleierz and Braunbleierz''). The phosphate was first distinguished chemically by M. H. Klaproth in 1784, and it was named pyromorphite by J. F. L. Hausmann in 1813. The name is derived from the Greek for ''pyr'' (fire) and ''morfe'' (form) du ...
