Groundwater contamination by toxic metals and organic compounds is a serious environmental and public health problem (Crini 39). Many of the common contaminants in wastewater are known to be toxic or carcinogenic. Common groundwater contaminants include heavy metal ions, aromatic compounds, and dyes. Additionally, heavy metals are not biodegradable and tend to bioaccumulate, leading to various diseases and disorders. Mercury and cadmium are among the most toxic metals and are very damaging to the environment. Additionally, chromium (VI) is a wide-spectrum toxin, as it is toxic to bacteria, plants, animals, and humans. Organic compounds in groundwater are ...

Lab 2 – Water Quality and Contamination

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

Uranium (U) element was discovered by a German chemist, Heinrich Klaproth, in 1789. Uranium is a radioactive element with an atomic weight of 238.02891 and an atomic number of 92. The uranium element initially discovered by Heinrich was an oxide, uranium oxide. A French chemist, Eugène-Melchoir Péligot, was the first person to produce pure uranium by reacting it with potassium in a heated platinum crucible. The element’s radioactive properties were established in 1896 by a French physicist known as Antoine Henri Becquerel. Currently, uranium can be extracted from various ores such as carnotite (K2(UO2)2VO4· ...

Vince Gilligan’s crime/family drama Breaking Bad (2008-2013) is often cited as one of the greatest television shows ever made, one of the best examples of the era of prestige cable drama. Telling the story of science teacher-turned-meth-cook Walter White (Bryan Cranston) and his burnout assistant Jesse Pinkman (Aaron Paul), Breaking Bad’s serialized narrative, layered performances and dedication to dynamic visual storytelling elevate it in ways not enjoyed by most cable dramas. Perhaps one of the most presentational and ambitious episodes of the series is the tenth episode of season three, “Fly,” directed by Rian Johnson. A classic ...
