Retraction Note to: Characteristics of heavy metal pollutants in groundwater based on fuzzy decision making and the effect of aerobic exercise on teenagers

Abstract

Due to its abundant reserves and pure water quality, groundwater is an important water resource on the earth, which is widely distributed and easy to use, so it is widely used in industrial production, agricultural production, and domestic drinking. Most urban and rural areas in China use groundwater as drinking water source, and the quality of groundwater is closely related to the life of residents. Indiscriminate use of agricultural fertilizers, wanton discharge of industrial wastewater, and untreated wastewater will cause heavy metal pollution in groundwater. Groundwater is polluted by characteristic pollutants, which makes it difficult to deal with, and the deeper the water layer is, the lower the self-purification capacity will be, threatening the health of residents. In this paper, the groundwater samples of 58 towns in l area were collected as the investigation area, and the contents of fluorine ion and 16 kinds of metals and nonmetals were analyzed and discussed by ICP-MS and other equipment, as well as the characteristics of rural groundwater pollution in dry period. At the same time, the index model fuzzy decision making and single factor of health risk assessment model were used to evaluate the carcinogenic and non-carcinogenic risk. Obesity among Chinese adolescents is also a very worrying problem. The current literature supports many weight loss methods. Exercise weight loss can not only reduce fat, but also improve physical strength. In the long run, it can make us gain synergy. In life, people are aware of the impact of aerobic exercise on weight loss, so they rarely use high-intensity temporary strength for training. According to the research of fuzzy decision making, it is applied to groundwater and aerobic movement, so that it can be effectively improved.
