“…The higher value of CH in these cities may be due to industries, transport activities, energy sector, China, Pakistan Economic Corridor, and residential activates, etc. The urban areas showed high concentrations of chemicals as reported in China (Xiao et al 2014) and Pakistan (Murtaza et al 2018). The CH value range is recorded 1-1.2 kg/m 2 /s over Pakistan.…”

“…The results suggested that higher contribution of transport sectors might be due to the production and usage of CH in this sector as compared to other sectors. Another factor may be that most of the human activities (industrial area and the huge traffic) take place in the northern and eastern areas of Pakistan (Murtaza et al 2018). Karachi, Pakistan's largest city with a high percentage of industrial activities and fuel combustion, showed exceptionally high concentration in the south of the country.…”

Chlorinated hydrocarbons (CH) are emitted into the atmosphere by different anthropogenic activities and natural process, which could contribute to global warming and rapid melting of glaciers and cause serious health hazards. The objective of this research was to figure out the spatio-temporal distribution of CH concentration and the influence of climatic variables on CH concentration over Pakistan. Chlorinated hydrocarbons (CH) data was collected from the GEIA Database emissions dataset. The results indicated that CH were significantly distributed over Pakistan in different seasons. Highest concentration of CH was recorded in winter and autumn seasons as compared to the spring and summer seasons. The concentration of CH was maximum in winter season as compared to the other seasons. Spatial analysis indicated that CH concentration (1-1.2 kg/m 2 /s) was higher in the Punjab Province (Lahore, Rawalpindi, Gujrat, Sialkot, and Multan) as compared to the other Provinces, suggesting it could be due to high transport and industries in the region. Surface temperature and specific humidity showed significant positive correlation with CH across the Pakistan. Rainfall showed positive correlation with CH at the south part during spring and autumn seasons while on the north part of Pakistan during summer and winter seasons.The results suggest that CH could cause climate change through radiative forcing or climate forcing in Pakistan. Waste sector and solvent sector (30%) revealed higher level of CH during 2000. This study demonstrates the changing of climatic conditions in different seasons generate a special circumstance for accumulation and transportation of CH in Pakistan.
