What Are PCBs?

PCB contamination is saturated in the Housatonic River and New Bedford Harbor in Massachusetts. PCBs were banned in the U.S. 1979 amid suggestions that these chemicals could have unintended impacts on human and environmental health. These chemicals were banned in the U.S. 1979 amid recommendations that PCBs could have unintended impacts on human and environmental health.

From the 1920s until their ban, an estimated 1.5 billion pounds of PCBs were designed for things such as microscope oils, electric insulators, capacitors, and electric appliances such as tv refrigerators or sets. PCBs were also sprayed on dirt roads to carefully keep the dust down prior to knowing some of the unintended consequences from widespread use.

Prior to the ban in 1979, PCBs entered the air, water, and ground during manufacture and use. Wastes from the manufacturing process that contained PCBs were often placed in dump sites or landfills. Occasionally, accidental spills and leaks from these facilities or transformer fires could result in PCBs entering the environment.

PCBs can be found worldwide. PCBs can degrade, or breakdown in the environment, but the process greatly depends on the chemical makeup of the PCBs. The degrading process depends upon where the PCBs are in the environment also. Typically, PCBs are divided in the environment by sunlight or by microorganisms either. Sunlight plays an important role in the breakdown of PCBs when these are in the air, shallow water, or surface soils. Microorganisms, such as bacteria, algae, or fungi, biodegrade PCBs when within dirt or sediments.

I got right through and then it was on to Customs, where every handbag was scanned through a huge X-ray machine. I didn’t see one bag exposed for inspection. There have been so many items I put didn’t bring beside me because I didn’t want to take a chance that they might be confiscated, and here it turns out that I could have brought virtually anything with me!

Then we walked to the passenger pickup area where I searched the audience for a familiar face. I had been greeted by Adnan, Adnan’s, and Adam sibling Adel. These were all dressed up in the original white dresses men wear called shoes and wore the red and white checkered headgear. My Arabian welcoming committee was much smaller than Adam’s have been because I came during Ramadan, when most people stay up forever to eat and then sleep during the day so they don’t feel as much hunger or thirst. So my entrance took the back seat to their sleep!

I couldn’t believe I was in Arabia after all these years. It was something I had developed imagined. Adnan was proud and excited showing me our new vehicle. It really is a champagne-colored Toyota Fortuner, a make of SUV not sold in America. The defensive plastic was on the seats still, headrests, and visors. There was practically no traffic at all on the drive from the airport terminal to your house.
