Abstract:
Fipronil is a phenylpyrazole insecticide used in various agricultural, horticulture, and veterinary practices. Besides its wide range of applications, it also causes severe health hazards to the non-targeted organisms especially in developing countries. Fipronil showed hepatotoxic, nephrotoxic, neurotoxic, and altered reproductive development and endocrine system in humans and animals. Several methods have been already introduced for the removal of toxic fipronil including physicochemical and by the implementation of microorganisms. The microbial methods of fipronil degradation are the most promising and environmentally sustainable. The remediation of fipronil from the environment is an emerging task due to its enhanced residual concentration. Herein, we discuss the bioremediation potential of microbial strains in contaminated soil and water. It is shown that fipronil can be remediated from the environment using combined ecotechnologies. This review discusses the toxicity, different physico-chemical and biological methods, and sustainable developments in fipronil-contaminated agriculture and aquatic environments.

Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
