Abstract : This report examines the environmental behavior and fate of nonradioactive hazardous chemicals, methods for assessing environmental impacts, and alternatives for achieving land decontamination and cleanup. Nonradioactive hazardous chemicals can be reactive, corrosive, or toxic. Reactive chemicals may be explosive, flammable, or capable of undergoing spontaneous change upon exposure to air, water, or a mixture of other chemicals. Toxic chemicals a high probability of being carcinogenic, mutagenic, teratogenic, or lethal to humans and wildlife. The major pathways of entry into the environment are accidents in handling and storage, industrial accidents, illegal or accidental dumping, leaching from buried toxic wastes, land-treatment of waste waters, herbicide and pesticide use, and use of industrial products. Keywords: Countermeasures, organic chemicals, toxic metals, food-chain pathways, assessment models, land decontamination.
