Besides affecting health, prolonged exposure to air pollution can also reduce employee’s productivity, finds a study.
The study showed that daily fluctuations in pollution did not immediately affect the productivity of workers.
However, a definite drop in output was witnessed when measured for more prolonged exposures of up to 30 days, the researchers said.
In addition, working in a highly polluted setting for long periods of time could affect your mood or disposition to work.
“Our aim with this research was to broaden the understanding of air pollution in ways that have not been explored. We typically think that firms benefit from lax pollution regulations, by saving on emission control equipment and the like; here we document an adverse effect on the productivity of their work force,” said Alberto Salvo, Associate Professor from the National University of Singapore (NUS).
For the study, published in the American Economic Journal: Applied Economics, the team gathered information from textile factories in China which involved interviewing managers before obtaining access to data.
They compared how many pieces of fabric each worker produced each day to measures of the concentration of particulate matter that the worker was exposed to over time.
“We found that an increase in PM2.5, by 10 micrograms per cubic metre sustained over 25 days, reduces daily output by one per cent, harming firms and workers,” said Haoming Liu, Associate Professor of the varsity.
“The effects are subtle but highly significant,” said Liu.
The researchers, however, remain agnostic about the reasons that explain why productivity goes down when pollution goes up, the study noted. (IANS)
Reductions in Air Pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, a new study suggests.
The study, published in the journal Annals of the American Thoracic Society, reviewed interventions that have reduced air pollution at its source. It looked for outcomes and time to achieve those outcomes in several settings, finding that the improvements in health were striking.
Starting at week one of a ban on smoking in Ireland, for example, there was a 13 per cent drop in all-cause mortality, a 26 per cent reduction in ischemic heart disease, a 32 per cent reduction in stroke, and a 38 per cent reduction in chronic obstructive pulmonary disease (COPD). Interestingly, the greatest benefits in that case occurred among non-smokers.
“We knew there were benefits from pollution control, but the magnitude and relatively short time duration to accomplish them were impressive,” said lead author Dean Schraufnagel from the American Thoracic Society in the US.
“Our findings indicate almost immediate and substantial effects on health outcomes followed reduced exposure to air pollution. It’s critical that governments adopt and enforce WHO guidelines for air pollution immediately,” Schraufnagel added.
According to the researchers, In the US a 13-month closure of a steel mill in Utah resulted in reducing hospitalisations for pneumonia, pleurisy, bronchitis and asthma by half.
School absenteeism decreased by 40 per cent, and daily mortality fell by 16 per cent for every 100 µg/m3 PM10 (a pollutant) decrease.
Women who were pregnant during the mill closing were less likely to have premature births.
A 17-day ‘transportation strategy,’ in Atlanta, Georgia during the 1996 Olympic Games involved closing parts of the city to help athletes make it to their events on time, but also greatly decreased air pollution.
In the following four weeks, children’s visits for asthma to clinics dropped by more than 40 per cent and trips to emergency departments by 11 per cent. Hospitalizations for asthma decreased by 19 per cent.
Similarly, when China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.
“Fortunately, reducing air pollution can result in prompt and substantial health gains. Sweeping policies affecting a whole country can reduce all-cause mortality within weeks,” Schraufnagel said.
