The need for more intensive utilization of expensive and complex equipment has brought about a considerable expansion of shift working. This expansion has been not so much in the number of people on shift work as in the variety of categories of staff who are asked — or required — to work shifts, and in the diversification of patterns of shift working.

This paper aims to investigate the environmental impact of various pollutant emissions including carbon monoxide (CO), carbon dioxide (CO₂), nitrogen oxide (NO_x) and hydrocarbon (HC) from aircraft exhaust gases during the landing and take-off (LTO) cycles at Eskisehir Hasan Polatkan Airport, Turkey, between 2017 and 2018.

The methodology approach used to calculate the emissions from aircrafts is based on the ICAO databank and the actual data records taken from Presidency of The Republic of Turkey Directorate of Communications (DoC).

The maximum amount of total fuel burnt during the two years is 80.898 and 70.168 tons in 2017 and 2018, respectively, while the average fuel burnt per year from 2017 to 2018 is approximately 369.773 tons. The highest CO, CO₂, NO_x and HC emissions are found to be 248.3 kg in 2017, 261.380 tons, 1.708 tons and 22.15 kg, during the 2018 year, respectively. Average CO, HC, NO_x and CO₂ emissions amount per year are observed to be 1.392 tons, 135 kg, 6.909 tons and 1,143 tons, respectively. Considering the average of total emission amount as an environmental factor, as expected, CO₂ emissions contributed the most to the total emissions while HC emissions contributed the least to the total emissions from the airport.

The study presents the approach in determining the amounts of emissions released into the interannual atmosphere and it explicitly provides researchers and policymakers how to follow emissions from commercial aircraft activities at different airports.

The value of the study lies in the transparent computation of the amounts of pollutants by providing the data directly from the first hand-DoC.

The most significant sources and environmental pathways of manmade radionuclides have recently been examined by the RADPATH (Biochemical Pathways of Artificial Radionuclides) project, which was initiated under the auspices of the SCOPE (Scientific Committee on Problems of the Environment) unit. The accident at the Chernobyl nuclear power plant in 1986, with its associated radionuclide release, has provided an unexpected data source concerning movement of materials within various environmental compartments. Outlines some of the findings of the SCOPE‐RADPATH project, a particular focus of which was the Chernobyl accident, with reference to the atmospheric, terrestrial, aquatic and urban environments.

The purpose of this paper is to outline the level of audible carbon monoxide (CO) alarm ownership. In this particular paper the data collected by the fire and rescue services from West Midlands and Merseyside will be analysed, and discussed.

Research was conducted in two stages. Using the indices of multiple deprivation identified whether households in the top and bottom four areas owned an audible alarm. In stage two data loggers were placed into homes to take readings every minute for a total period of three days to three weeks.

There was a noticeable trend that deprived areas were less likely to own audible CO alarms than homes in non-deprived areas. All homes surveyed in stage two had CO levels >0 which further emphasises that anyone can be under health risk and that perhaps the maintenance of gas appliances and other sources is not being conducted at regular intervals.

This paper aims to raise awareness regarding not only the symptoms during CO poisoning but also the ones that have been reported to occur after treatment. It will also disseminate information as to what areas have low alarm ownership and thus more at risk of poisoning. It is hoped that findings from papers such as this one will promote more stringent maintenance and replacement requirements for gas or solid fuel appliances.

Pilot study for the comparison of two English cities has not been conducted before and may lead to more studies of this kind.
