Occupational Safety and Health: Worker Safety in the Space and Science Industries
Propelled by the Cold War, research and testing of rocket motors and fuels flourished in the mid 1900s, exposing workers to the acute effects of toxic chemicals and the as yet unknown chronic and long term effects. Aroun..
Occupational Safety and Health: Worker Safety: Looking Back
Although concern for worker safety was expressed as far back as Hypocrites, it wasn't until 1911, in the wake of the Triangle Shirt Factory fire, that the first worker compensation laws were enacted.
Over-Consumption
Paul Ehrlich, best known for his work on population growth, cites over-consumption as one of the principle threats to the environment.
Paths of Pollution: Cleaning Up the Fox River
The potentially responsible parties for the discharge of PCBs into the Fox River-the companies along the Fox River-propose the natural attenuation method of remediation. EPA does not consider this natural burial of the c..
Paths of Pollution: Great Lakes: Remediation Efforts
Remediation efforts in the Great Lakes Basin are ongoing. Most of the industry is found along the rivers and tributaries, and the objective is to remediate the sediments before they are swept into the open lake. The goal..
Paths of Pollution: Great Lakes: Remediation Methods
The three main methods of remediation are hydraulic dredging, natural attenuation, and capping the contaminated sediments with a layer of clay or sand. Dredging is the preferred method because of its permanency. The cont..
Paths of Pollution: Great Lakes: The Health Effects of PCBs
The population of the Great Lakes region continues to suffer the health affects of PCBs. It is a probable carcinogen, it can affect the immune system, cause IQ deficits and problems integrating socially, and reproductive..
Paths of Pollution: Great Lakes: The Problem of Cross-Contamination
Areas that are not directly contaminated by industrial pollutants can be cross-contaminated through the migration of fish and water fowl. The Wold River is such a spot.
Paths of Pollution: PCBs and the Great Lakes
As industries began to proliferate around the Great Lakes and its tributaries, contamination also began to accumulate in its waters. PCBs, which do not biodegrade, were routinely discharged into the environment before sc..
Persistent Organic Pollutants
Zoologist and World Wildlife Fund senior scientist Theo Colborn talks about the global problem of persistent organic pollutants. She observes that it's a difficult problem to solve because some nations continue to use ch..
