Phthalates are ubiquitously present environmental contaminants. Air and dust are the most important mediums of exposure to phthalates. The present study reviews the presence of phthalates in the air and dust reported from different countries in the last ten years (2007-2017). The phthalate concentrations revealed wide heterogeneity with a mean and median value 6 ± 19 μg/m and 0.5 μg/m respectively in the air and 1.5 × 10 ± 2.2 × 10 μg/g and 7.8x10μg/g respectively in the dust. The highest phthalates levels in the air were reported from India (1.1 × 10 μg/m) and in dust from Bulgaria (1.2 × 10 μg/g). Overall higher levels were reported from developing countries as compared to developed countries. Di (2-ethylhexyl) phthalate (DEHP) and Di-n-butyl phthalate (DBP) were found to be predominant in both air and dust. Temperature, humidity, air exchange rate, building material and indoor maintenance were reported as the important factors influencing the levels of phthalates in the air and dust. In addition to policy level interventions, reducing the use of phthalate containing materials and controlling the factors which enhance the emission from existing sources can help in reducing human exposure to phthalates.

Cement dust is a primary contributor to air pollution and is responsible for causing numerous respiratory diseases. The impact of cement dust exposure on the respiratory health of residents is increasing owing to the demand for construction associated with urbanization. Long-term inhalation of cement dust leads to a reduction in lung function, alterations in airway structure, increased inhalation and exhalation resistance, and heightened work of breath.

Phthalates (PAEs) are a group of endocrine-disrupting environmental chemicals (EEDs) that pose significant risks to human health. PAEs are widespread in various environmental media, including air, dust, water, and soil, and are subject to both horizontal and vertical migration. Human activities significantly influence the distribution of PAEs, yet current research on this relationship remains limited.

Urbanization and industrialization have drastically increased ambient air pollution in urban areas globally from vehicle emissions, solid fuel combustion and industrial activities leading to some of the worst air quality conditions. Air pollution in Ghana causes approximately 28,000 premature deaths and disabilities annually, ranking as a leading cause of mortality and disability-adjusted life years. This study evaluated the annual concentrations of PM NO and O in the ambient air of 57 cities in Ghana for two decades using historical and forecasted data from satellite measurements.

The scales of the gold-dust weevil are green because of three-dimensional diamond-type chitin-air photonic crystals with an average periodicity of about 430 nm and a chitin fill fraction of about 0.44. A single scale usually contains one to three crystallites with different lattice orientations.
