The garden-city model, characterised by sprawling urban expansion and extensive open spaces, features green and water surfaces alongside substantial road networks, large parking lots and unshaded lands. This diverse landscape contributes to uneven air temperature distribution within the city. Our study investigated urban heat island (UHI) patterns in various urban environments within Putrajaya, focusing on rural, business, residential and near-water areas. Atmospheric data were collected over a year. Putrajaya exhibits two distinct UHI patterns: cool-day-hot-night in residential zones and hot-noon-temperate-elsewhere in impermeable areas. Business areas display alternating patterns based on seasonal climatic conditions and anthropogenic factors. The efficacy of artificial water bodies as a UHI countermeasure in garden cities depends on the size of the water body and the nature of the surrounding land cover. Shaded and green areas exhibit UHI intensities limited to 3°C, while impermeable areas, regardless of proximity to water surfaces, experience UHI up to 6°C. Overall, the garden-city model tends to restrict UHI variations within −1 to 3°C compared to −2 to 4°C in nearby Kuala Lumpur.

This study investigates the environmental impact of end-of-life vehicle (EL V) recycling operations by assessing pollution parameters and noise levels at formal and informal recycling centers compared to a green zone reference area. U sing an integrated monitoring system. This research measured concentrations of particulate matter (PM2.5, PMlO), nitrogen dioxide (N02), carbon dioxide (C02), ozone (03), and noise levels at selected sites in Selangor, Malaysia. Results reveal elevated pollutant concentrations and noise levels at both formal and informal EL V recycling centers relative to the green zone reference area. Diurnal variations in pollutant levels highlight the influence of operational activities and atmospheric conditions. The findings underscore the need for stringent regulatory measures and pollution control strategies to mitigate environmental and health risks associated with EL V recycling activities and promote sustainable practices in the recycling industry.
