Abstract:

Antibiotic compounds have the characteristics of broad-spectrum, quick-acting, relatively low cell toxicity, etc., and are widely used in the treatment of bacterial infection in mammals, animal feed or plant organic fertilizers. With the construction of agricultural modernization, nearly 47 kinds of antibiotic compounds directly or indirectly have invaded the soil ecosystem through the application of various compound organic fertilizers, agricultural irrigation water, sewage and man-made pollutants dumping, etc. Between 2013 and 2017, the average antibiotic content of agricultural land in China increased by about 18.6%, and the pollution equivalent of some sampled land exceeded 157% of the normal value set by the United Nations. Excessive antibiotics can interfere with soil biota. Relevant studies show that antibiotic molecules in the soil could enter the plant body through transpiration and interfere with physiological activities such as root respiration and transpiration. In addition, antibiotics could also spread and accumulate through the food chain, thereby expanding the scope and harm of their pollution. This article made statistics and summaries on the relevant research on soil antibiotics from 2010 to 2020, and comprehensively discussed the research progress of the environmental behavior and temporal and spatial distribution of antibiotics in soil, aiming to provide theoretical references for the research on antibiotics in soil.

Key words: soil, antibiotics, environmental behavior, temporal and spatial distribution, pollution
