Analysis of monitoring results of coal-burning-borne arsenic poisoning in Xiangyang City, Hubei Province from 2014 to 2018 / 中华地方病学杂志

ABSTRACT

Objective:To analyze the monitoring results of coal-burning-borne arsenic poisoning in Xiangyang City, Hubei Province from 2014 to 2018.Methods:In 2014-2018, according to "the Monitoring Plan for Coal-burning-borne Endemic Arsenic Poisoning in Hubei Province", five villages in Xiangyang City were selected as monitoring sites every year. Coal samples from 8 households were collected by four-point method after multi-point sampling and mixing in each site every year, coal arsenic content was detected. Urine samples of 10 adults (half male and half female) were collected to detect the arsenic content in urine. The disease condition of residents with coal-burning-borne arsenic poisoning was surveyed.Results:From 2014 to 2018, there was a significant difference in coal arsenic content ( F=21.572, P < 0.05), and the coal arsenic content in 2018 was significantly lower than those in other years ( P < 0.05); there was no significant difference in arsenic content in adult urine (χ 2=1.647, P > 0.05). During the past five years, 266 suspected cases, 736 mild cases, 633 moderate cases and 18 severe cases were detected. There was no significant difference in the detection rates of arsenic poisoning among different years (χ 2=1.094, P > 0.05). Conclusions:The detection rate of coal-burning-borne arsenic poisoning in Xiangyang City from 2014 to 2018 is relatively stable, and the management of high arsenic coal has achieved initial results. It is necessary to further strengthen disease monitoring, energy diversification transformation and health education of residents, so as to further improve the prevention and management mechanism of coal-burning-borne arsenic poisoning.
