Based on the date of the main pollutant discharge and the change of pollutant concentration in Z city, this study performed the statistical analysis of the concentration data in excel. The data covers 3 years from 1 January 2015 to 31 December 2017. An exposure-response relationship model was used established to evaluate the health hazards caused by air pollution and the corresponding economic losses, further analyzing the relationship between air pollution, health hazards, and economic benefits. The results of the study showed that the changes in SO(2) and NO(2) concentrations in Z City from 2015 to 2017 have a great influence on the mortality rate of the local population, respiratory mortality, the rate of internal medicine of outpatients, and the rate of chronic bronchitis disease. The economic losses between 2015 and 2017 caused by PM10, the primary pollutant in the air, were 3.9 billion, 3.5 billion, and 2.9 billion respectively, accounting for 3.60%, 2.88%, and 2.09% of Z City's GDP, which were enormous. Finally, countermeasures of feasible treatment and in government performance were put forward.

Purpose
The purpose of this study is to examine whether and how abusive supervision climate impacts team conflict from a mindfulness perspective. Prior research has identified serious dysfunctional effects of abusive supervision climate in teams. Team conflict, which is often a signal for dysfunctional relationships in teams, has however received limited attention. To contribute to this line of research, this study develops and tests a theoretical model on the role of team mindfulness in understanding the link between abusive supervision climate and task, process, and relationship conflict.


Design/methodology/approach
To test the theoretical model, this study collected and analyzed two-wave time-lagged data from 499 employees in 92 teams.


Findings
The results showed that abusive supervision climate aggravated task conflict and process conflict via diminishing levels of team mindfulness. Abusive supervision climate also exacerbated relationship conflict, but the effects did not occur via a decrease in team mindfulness.


Practical implications
While it may not always be possible to prevent the development of an abusive supervision climate in workplaces, other interventions may prevent conflict in teams with abusive leaders. As indicated by the findings, task conflict and process conflict may be reduced if teams are high on mindfulness. Interventions that stimulate team mindfulness might thus improve collaboration in teams with abusive leaders.


Originality/value
This research offers novel insights regarding how abusive leaders might instigate conflict within teams. Specifically, through the unique perspective of mindfulness, the authors are able to offer new insights into how abusive supervision climate affects task, process and relationship conflict. This study offers a novel, yet important, lens to examine how conflict occurs in teams.
