The substance which cannot be broken down easily like pesticides, insecticides (DDT), mercury, glass particles etc. These remains as such in environment for a very very long time. 

Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered e-waste.

Non-biodegradable wastes can not be broken down by decomposes because they do not have enzymes for the same. They are commonly man made. They are not degraded by micro organism. They pile up and accumulate in nature. 

Biodegradable wastes are naturally degraded by microbes they can also be disposed of thoughts waste treatment plants or converted into an agriculture resources of nature and compost. 

Biomagnification is the accumulation or increasing bioconcentration of lipophilic pesticides in the top members of the food chain. During biomagnification, the concentration of pesticides goes on increasing according to the food chain and highest values occur in the consumers of the top trophic level. So, the value of pesticide will go on increasing from the soil, to the plant and to the bird. 

Dichlorodiphenyltrichloroethane (DDT) is an organochlorine compound used as an insecticide in agricultural fields. The major disadvantage of DDT is bioaccumulation or not easily degrading nature, due to fat solubility it is accumulated in living tissues. The human body is not able to break it which cause its build up in the food chain and causing poisoning in the animals. Its effects can be seen in birds as the production of thin eggshells vulnerable to damage.

Dichlorodiphenyltrichloroethane (DDT) is an organochlorinated chemical used as an insecticide. This compound is highly stable in the environment. It readily stays in the adipose tissues of the living organisms and accumulates at the successive trophic level to cause the biomagnification. In soil, it is not acted upon by the decomposing bacteria so it remains persistent for years. Due to its nonbiodegradable nature, it became a major pollutant of the agricultural soil. Its use was banned by the Stockholm Convention of 2001.

A non-biodegradable pollutant is the one that could not be broken down or decomposed by the decomposing fungi and bacteria present in the water and soil. DDT is an organochlorinated compound used as an insecticide that is chemically stable. It does not dissolve in water rather it mixes with the adipose tissue in the living organisms and persists in the food chain, causing biomagnification. In the soil, it destroys the microbial fauna.
