The economy of Galena Park began to suffer in the early 1980s, when cranes used to haul ship cargo were reduced; prior to the early 1980s, a team of workers, known on the docks as longshoremen, took up to one week to unload cargo off a ship. Many lived in the Galena Park area and contributed to its local economy.Galena (PbS): Class 2: Galena is cubic, comparatively soft (hardness 2.5), dark gray with a faint blue nuance, and a bright metallic luster. It is the main mineral of lead, but is often associated with economic amounts of silver. This element may replace lead in the lattice, usually coupled with bismuth or antimony, but in many “argentiferous

Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.Galena also has two governing bodies – the Louden Tribal Council and the City Council. The population is a mix of Alaskan Native and non-native residents. In many communities throughout Alaska, tribal communities retain traditional claims to land and resources. In Galena, this traditional system of resource management posed aThis work is therefore conceptualized to advance knowledge on the potential economic burden of heavy metal pollution of the water, sediment, and soil components of the environment within the communities in Ebonyi State, Nigeria where galena has been mined for many years and is still being mined for lead production.
