TL;DR: The latter part of this review considers organic compounds in the following order: agrochemicals, petroleum and crude oil hydrocarbons, PAHs and PCBs.
Abstract: Due to their biological, chemical and physical actions, earthworms can be directly employed within bioremediation strategies to promote biodegradation of organic contaminants. Earthworms have been shown to aerate and bioturbate soils and improve their nutritional status and fertility, which are variables known to limit bioremediation. Earthworms have also been shown to retard the binding of organic contaminants to soils, release previously soil-bound contaminants for subsequent degradation, and promote and disperse organic contaminant degrading microorganisms. This review discusses these earthworm actions upon the soil environment and how they might influence the fate and behaviour of soil associated organic contaminants, subsequently improving bioremediation potential. The latter part of this review considers organic compounds in the following order: agrochemicals, petroleum and crude oil hydrocarbons, PAHs and PCBs.

Abstract: Pesticides usages are intensive all over the world to control insect pests even a commitment to the rapid adoption of integrated pest management techniques. Pesticides are ranked as the most widely distributed chemical contaminants of the environment in the twentieth century. According to data compiled by the United States Environmental Protection Agency and the World Health Organization, over 1000 compounds are used as pesticides, representing many different chemical classes: carbamates, thiocarbamates, organophoshates, dipyridyls, triazines, phenoxyacetates, coumarins, nitrophenols, pyrazoles, pyrethroids, and organic compounds containing chlorine, phosphorus, tin, mercury, arsenic, copper, etc. Millions of tons of pesticides are produced and used annually in close association with agriculture. Many articles, reviews and books are devoted to pesticides.

Abstract: Extensive use of pesticides in agriculture poses a major hazard toward environment and human health thus leading to harmful ailments toward the society. Hazards associated with exposure of agrochemicals and susceptibility of farmers are due to lack of knowledge about the proper handling of pesticides and their safe use. Huge areas of arable land are being subjected to chemical contamination owing to intense use of agrochemicals in the farming lands. Toxic pesticides, such as chlordane, dieldrin, heptachlor, mirex, and toxaphene, have contaminated the farmlands all over the globe specifically in the developing nations. Vermiremediation is an excellent technique for removal of agrochemicals contamination from soil. Earthworms possess the ability to disperse the toxins and reduce the overall concentration of pesticides. Vermitechnology has emerged as an economically feasible, environmentally sustainable, and a socially acceptable technology all over the world. Earthworms are tolerant and can help in the removal of an extensive range of organic and inorganic agrochemicals. Earthworms bring about the removal of organic contaminants through biodegradation, biotransformation, and physical actions. Earthworm participation enhances natural biodegradation of harmful agrochemicals, thus converting them into useful stabilized resource.
