Air Evaluation at Jeddah 1ST Industrial City

Received Date:23 July 2023, Accepted Date:18 September 2023, Published Date:25 October 2023


Objectives: The study aimed to evaluate Air at Jeddah 1st Industrial City using six pollutants, include nitrogen dioxide (NO2), ground level ozone (O3), sulfur dioxide (SO2), carbon dioxide (CO2), carbon monoxide (CO) and particulate matter (PM10& PM2.5) Methods: Methodology of the study focused on site visits of two factories at 1st industrial city including several locations, physical monitoring using approved instrument of Air pollution, data analyzing using specific software, representing the findings in flowcharts and comparing the values to the standards. In order to monitor NO2, SO2, CO, O3, PM2.5, and PM10 pollutants in first industrial city in Jeddah. Findings: Measurements was found that NO2 and SO2 exceeded the permissible limits in certain places, the other parameters show good compliance to NCEC limits. These findings, which were confirmed by the COVID-19 lockdown period in Jeddah, show a very significant decline in pollutants and, as a result, a very significant improvement in air quality. This was caused by noticeably lower levels of NO2 (- 44.5%), CO (- 41.5%), and PM2.5 and PM10 (- 29.5%, each) than the pre-lockdown average, which were observed in Jeddah, the capital city, during the quarantine. According to the study's findings, the decline in transportation, industrial processes, and other economic activities was significantly associated with the concentrations of pollutants. The global lockdown measures have a negative impact on the main causes of air pollution. Novelty: The findings of the current study complement studies conducted during the COVID-19 pandemic, which demonstrated a beneficial reaction to lockdown and show variances in reading measures of the environmental indicators. The outcomes are the first since issuing the standards of NCEC and it shows good compliance. it can also be applied to develop new methods and controls for raising air quality in the future.
