Paraquat is a highly toxic herbicide commonly used to control weeds in agricultural and non-agricultural settings. It is a non-selective herbicide, meaning it can kill a wide range of plants. Paraquat is known for its fast-acting and non-residual effects, making it a popular choice for weed control. However, paraquat is also highly toxic to humans and animals. It can cause severe poisoning if ingested, inhaled, or absorbed through the skin. The toxic effects of paraquat primarily affect the lungs, kidneys, liver, and central nervous system. Symptoms of paraquat poisoning may include difficulty breathing, chest pain, vomiting, abdominal pain, and confusion. Due to its high toxicity, paraquat is subject to strict regulations in many countries. In some places, it is banned or heavily restricted. Safety precautions, such as protective clothing and equipment, are necessary when handling paraquat to minimize the risk of exposure.
