The effect of air quality parameters on new COVID-19 cases between two different climatic and geographical regions in Turkey.

Different health management strategies may need to be implemented in different regions to cope with diseases. The current work aims to evaluate the relationship between air quality parameters and the number of new COVID-19 cases in two different geographical locations, namely Western Anatolia and Western Black Sea in Turkey. Principal component analysis (PCA) and regression model were utilized to describe the effect of environmental parameters (air quality and meteorological parameters) on the number of new COVID-19 cases.

Risk assessment and spatial distribution of heavy metal in street dusts in the densely industrialized area.

Street dust samples can be used as an indicator for pollution monitoring especially in big cities. Various environmental problems have been experienced in Dilovasi, Turkey, and studies have been carried out in many different areas; however, no study has been conducted to examine the heavy metal content in street dusts. Therefore, in this study, 20 heavy metals, namely Si, Fe, Al, Zn, Mn, Ti, Cr, Ba, Pb, Ni, Sr, V, Co, Cd, Sb, As, Sn, Mo, Sc and Ag, in the street dusts of Dilovasi were investigated at 40 sampling points.

Assessment of HS and BTEX concentrations in ambient air using passive sampling method and the health risks.

Wastewater treatment plants (WWTPs) may be a source of nuisance in neighbouring places due to hydrogen sulphide (HS) and BTEX (benzene, toluene, ethylbenzene, and xylenes) emissions. In this study, samples were collected from WWTP workplace ambient air and outdoor ambient air around one of the largest WWTPs in Istanbul with a capacity of 250,000 m/day to evaluate the effects of HS and BTEX emissions. Samples were collected in three seasons for 15-day durations: winter (November 2015), spring (May 2015), and summer (August 2016).

Heavy metal content of total suspended air particles in the heavily industrialized town of Gebze, Turkey.

Air pollution is a serious environmental problem in industrialized towns, where a significant portion of the residents live in close proximity to factories and major highways with high traffic load. In this study, the ambient air quality in Gebze, an industrial region with an area of 438 km(2) and a population of 300,000, was characterized in terms for total suspended particulate matter and its composition of trace elements, i.e.
