Air pollution is a critical problem of the modern world, which has posed dangerous toxicological effects to the environment and human health. Haze is among the most significant pollutants of the new civilized world. Haze originates from various emissions; however, industrial processes and vehicular emissions contribute to significant factors that lead to the formation of haze. As documented by the World Health Organization, six principal air contaminants include ground-level ozone, lead, nitrogen oxides, carbon monoxides, and Sulphur dioxide. Continuous exposure to factors that contribute to the formation of haze promote various toxicological effects on human life such as cardiovascular as well as respiratory ailments, irritation of the eyes, long term chronic ailments like cancer, and neuropsychiatric issues. Air pollution by haze is reported to be a major environmental threat in the progression and incidence of some health complications such as low birth weight, asthma, Alzheimer and Parkinson’ diseases, lung cancer, autism, fetal growth, psychological problems, and ventricular hypertrophy. In this research paper, major causes of pollution by haze are discussed, emission sources and subsequent effects on human wellbeing.
Air Pollution by Haze
The social and economic activities of densely populated areas release large volumes of fine particulate matters. While these fine particulate materials unendingly pile beyond the ability of atmospheric self-cleaning to eradicate it, the haze weather is created. Haze weather is usually a mixture of the effects of stable and static weather. Current scientific studies conducted mostly in western Europe and North America demonstrate that air pollution in urban areas as a result of haze is triggering numerous health issues from eye itching to death. Increase in the speed for urbanization and industrialization in major cities of the world has led to growth in the badness of urban air pollution. “Amounts of fine particles are usually in thousands of micrograms in cubic meter across many cities of the world that are going through modern industrialization” (Astrobum, Apr 30 2017). Grievous installments of air pollution have wrapped a better part of the world. By November 2015, for instance, in China, the cities located to the northern area of the country have recently experienced high levels of haze due to the rise in particulate matter. The particulate matter increased from 360 to 700 µg/m3 up to 28 times much above the levels recommended by the world health organization (WHO).
Exposure to particulate matter has often been linked with numerous health problems; however, issues related to mortality are undeniably the most important to address since they are also among the prevalently amenable issues to the assessment of the world. Most epidemiological data and evidence on quality of air that would be employed in evaluating such approximations originate from developed nation. According to Costa et al., (2014) deaths caused by air pollution is on the rise, and the situation is worsening every year worldwide. Due to exorbitant problems triggered by air pollution in the cities today, the paper finds it critical to discuss the effects associated with haze in affecting the quality of air. It is, therefore, significant to describe the issue of haze in polluting the air, haze’s toxic impacts on the health of humanity and give necessary environmental frameworks as well as the necessary protocols in the industry of air pollution.
Ecologically, pollution of air can lead to severe environmental hazards to essential components of survival such as air, water, and soil. Moreover, it is a grievous risk to the diversity of life on earth. Compelling studies on the correlation between pollution of air and species diversity reduction vividly indicate the destructive impacts of environmental contaminants on the eradication of plants and animals’ diversity (Andersen et al., 2015). Toxicants that are suspended in the air may also prompt reproductive complications in animals’ species. Global climate change, acid rain, and temperature inversion, as a result of the release of greenhouse gases into the atmosphere, are among the most significant environmental effects of air pollution.
