The Affects of Hazardous Waste Material to the Environment

What are Hazardous Waste Materials?
Hazardous wastes are poisonous byproducts of manufacturing, farming, city septic systems, construction, automotive shops, laboratories, hospitals, and other industries such as Military installations and military training areas. The waste may be liquid, solid, or sludge and 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. The waste can harm humans, animals, and plants if they encounter these toxins buried in the ground, in stream runoff, in groundwater that supplies drinking water, or in floodwaters.

Some toxins, such as mercury, persist in the environment and accumulate. Humans or animals often absorb them when they eat fish.

A common hazardous waste facility is one that stores the waste in sealed containers in the ground. Less toxic waste that is unlikely to migrate, like soil with lead, is sometimes allowed to remain in place under the ground and then be sealed with a cap of hard clay.

Communities may eventually decide to use these sites for golf courses or parks, or to label them “Brownfield’s” sites, suitable for commercial or industrial uses. Even when used properly, many chemicals can still harm human health and the environment. When these hazardous substances are thrown away, they become hazardous waste. Some hazardous wastes come from our homes: our garbage can include such hazardous wastes as old batteries, bug spray cans, and paint thinner.

Regardless of the source, unless we dispose of hazardous waste properly, it can create health risks for people and damage the environment. Violations, like dumping hazardous waste in town dumps to avoid paying the fees charged by waste transporters and waste facilities, may result in hefty fines. In Osan, Airbase, we have an 18 month report on how much disposition of hazmat we have accumulated. Each type of hazmat of different kinds has a different system of proper waste disposal and they are tallied and totaled on what type of waste byproduct it is.

What are the effects of Hazardous waste Materials to the Environment?

Chemicals affect our everyday lives. They are used to produce almost everything we use, from paper and plastics to medicines and food to gasoline, steel, and electronic equipment. More than 70,000 chemicals are used regularly around the world. Some occur naturally in the earth or atmosphere; others are synthetic, or human-made. When we use and dispose of them properly, they may enhance our quality of life. But when we use or dispose of them improperly, they can have harmful effects on humans, plants, and animals.

What kinds of hazardous waste are there?

Most hazardous waste is identified by one or more of its dangerous properties or characteristics: corrosive, ignitable, reactive, or toxic. Corrosive – A corrosive material can wear away (corrode) or destroy a substance. For example, most acids are corrosives that can eat through metal, burn skin on contact, and give off vapors that burn the eyes Reactive – A reactive material can explode or create poisonous gas when combined with other chemicals. For example, chlorine bleach and ammonia are reactive and create a poisonous gas when they come into contact with each other. Toxic – Toxic materials or substances can poison people and other life. Toxic substances can cause illness and even death if swallowed or absorbed through the skin. Pesticides, weed killers, and many household cleaners are toxic.

Where does hazardous waste go?
Ideally, hazardous waste is reused or recycled. If this is not possible, hazardous waste is safely contained while it is stored, transported, and properly disposed of to prevent an accidental release into the environment. Advances in technology have greatly improved our ability to treat or dispose of hazardous waste in a way that prevents it from harming people or the environment. Typical methods of hazardous waste storage and disposal include surface impoundments (storing it in lined ponds), high temperature incineration (controlled burning), municipal and hazardous waste landfills (burying it in the ground), and deep well injection (pumping it into underground wells). More promising methods focus on minimizing waste, reusing and recycling chemicals, finding less hazardous alternatives, and
using innovative treatment technologies.

What are the dangers of hazardous waste management?
Proper management and control can greatly reduce the dangers of hazardous waste. There are many rules for managing hazardous waste and preventing releases into the environment. Even so, a lot can go wrong when we try to contain hazardous waste. Even the most technologically advanced landfills we build will leak some day. Tanks used for storing petroleum products and other chemicals can leak and catch fire; underground storage tanks weaken over time and leak their hazardous contents. Transportation accidents, such as train crashes and overturned trucks, can occur while transporting hazardous substances. There are also cases of intentional and illegal dumping of hazardous waste in sewer systems, abandoned warehouses, or ditches in remote areas to avoid the costs and rules of safe disposal.

How can hazardous waste affect us?
When hazardous wastes are released in the air, water, or on the land they can spread, contaminating even more of the environment and posing greater threats to our health. For example, when rain falls on soil at a waste site, it can carry hazardous waste deeper into the ground and the underlying groundwater. If a very small amount of a hazardous substance is released, it may become diluted to the point where it will not cause injury. A hazardous substance can cause injury or death to a person, plant, or animal if: A large amount is released at one time

A small amount is released many times at the same place
The substance does not become diluted
The substance is very toxic (for example, arsenic).
Coming into contact with a substance is called an exposure. The effects of exposure depend on: How the substance is used and disposed of
Who is exposed to it?
The concentration, or dose, of exposure
How someone is exposed
How long or how often someone is exposed.
Humans, plants, and animals can be exposed to hazardous substances through
inhalation, ingestion, or dermal exposure. Inhalation – we can breathe vapors from hazardous liquids or even from contaminated water while taking a shower. Ingestion – we can eat fish, fruits and vegetables, or meat that has been contaminated through exposure to hazardous substances. Also, small children often eat soil or household materials that may be contaminated, such as paint chips containing lead. Probably the most common type of exposure is drinking contaminated water. Dermal exposure – a substance can come into direct contact with and be absorbed by our skin.

Exposures
Exposures can be either acute or chronic. An acute exposure is a single exposure to a hazardous substance for a short time. Health symptoms may appear immediately after exposure; for example, the death of a fly when covered with bug spray or a burn on your arm when exposed to a strong acid such as from a leaking battery. Chronic exposure occurs over a much longer period of time, usually with repeated exposures in smaller amounts. Chronic health effects are typically illnesses or injuries that take a long time to develop, such as cancer, liver failure, or slowed growth and development. One reason chronic exposure to even tiny amounts of hazardous substances can lead to harm is bioaccumulation. Some substances are absorbed and stay in our bodies rather than being excreted. They accumulate and cause harm over time.
