TOXIC WASTE - "Synergistic Inequality of the True Apocalypse" 9


   Toxic waste is any material in liquid, solid, or gas form that can cause harm by being inhaled, swallowed, or absorbed through the skin. Many of today’s household products such as televisions, computers and phones contain toxic chemicals that can pollute the air and contaminate soils and water. Disposing of such waste is a major public health issue.

Classifying toxic materials

Toxic materials are poisonous byproducts as a result of industries such as manufacturing, farming, construction, automotive, laboratories, and hospitals which may contain heavy metals, radiation, dangerous pathogens, or other toxins. Toxic waste has become more abundant since the industrial revolution, causing serious global health issues. Disposing of such waste has become even more critical with the addition of

numerous technological advances containing toxic chemical components. Products such as cellular telephones, computers, televisions, and solar panels contain toxic chemicals that can harm the environment if not disposed of properly to prevent the pollution of the air and contamination of soils and water. A material is considered toxic when it causes death or harm by being inhaled, swallowed, or absorbed through the skin.

The waste can contain chemicals, heavy metals, radiation, dangerous pathogens, or other toxins. Even households generate hazardous waste from items such as batteries, used computer equipment, and leftover paints or pesticides.[1] Toxic material can be either human-made and others are naturally occurring in the environment. Not all hazardous substances are considered toxic.

The United Nations Environment Programme (UNEP) has identified 11 key substances that pose a risk to human health:

    Arsenic: used in making electrical circuits, as an ingredient in pesticides, and as a wood preservative. It is classified as a carcinogen.
    Asbestos: is a material that was once used for the insulation of buildings, and some businesses are still using this material to manufacture roofing materials and brakes. Inhalation of asbestos fibers can lead to lung cancer and asbestosis.
    Cadmium: is found in batteries and plastics. It can be inhaled through cigarette smoke, or digested when included as a pigment in food. Exposure leads to lung damage, irritation of the digestive track, and kidney disease.
    Chromium: is used as brick lining for high-temperature industrial furnaces, as a solid metal used for making steel, and in chrome plating, manufacturing dyes and pigments, wood preserving, and leather tanning. It is known to cause cancer, and prolonged exposure can cause chronic bronchitis and damage lung tissue.
    Clinical wastes: such as syringes and medication bottles can spread pathogens and harmful microorganisms, leading to a variety of illnesses.
    Cyanide: a poison found in some pesticides and rodenticides. In large doses it can lead to paralysis, convulsions, and respiratory distress.
    Lead: is found in batteries, paints, and ammunition. When ingested or inhaled can cause harm to the nervous and reproductive systems, and kidneys.
    Mercury: used for dental fillings and batteries. It is also used in the production of chlorine gas. Exposure can lead to birth defects and kidney and brain damage
    PCBs, or polychlorinated biphenyls, are used in many manufacturing processes, by the utility industry, and in paints and sealants. Damage can occur through exposure, affecting the nervous, reproductive, and immune systems, as well as the liver.
    POPs, persistent organic pollutants. They are found in chemicals and pesticides, and may lead to nervous and reproductive system defects. They can bio-accumulate in the food chain or persist in the environment and be moved great distances through the atmosphere.
    Strong acids and alkalis used in manufacturing and industrial production. They can destroy tissue and cause internal damage to the body.

The most overlooked toxic and hazardous wastes are the household products in everyday homes that are improperly disposed of such as old batteries, pesticides, paint, and car oil. Toxic waste can be reactive, ignitable, and corrosive. In the United States, these wastes are regulated under the Resource Conservation and Recovery Act (RCRA).
