Description

Technical Field

[0002] Organic pollutants refer to pollutants composed of natural organic substances in the form of carbohydrates, proteins, amino acids and fats, as well as some other biodegradable synthetic organic substances. They can be divided into two categories: natural organic pollutants and synthetic organic pollutants. Organic pollutants remain in the soil, causing crops to absorb pesticides from the soil, accumulating in plant roots, stems, leaves, fruits and seeds, and entering the human body through the food chain. After contaminated grains and vegetables enter the human body with food, they will cause symptoms such as fatigue, headaches, and loss of appetite. They will also reduce human immunity, harm the nerve center, induce changes in liver enzymes, and cause teratogenicity and carcinogenesis. Organic pollutants affect the ecosystem in the form of toxicity and reduction of dissolved oxygen in water and soil, endangering human health. Rapid and accurate detection of organic pollution types in soil and water can effectively understand the ecological environment of the site, trace the source of pollution, and carry out scientific management.
