As a result of the proposed study it was established that a complex action of carbon oxide and toluene++ in 300 mg/m3 concentration in a combination with heating microclimate (leading to a maximum heat labour condition) results in an increased total biological effect. The coefficient to the complex action of carbon oxide and heating microclimate is equal to 2.5 and toluene++ and heating microclimate to 1.9. These coefficients should be taken into account in establishing hygienic norms for the chemical compounds.

Harnessing street shade to mitigate heat stress: An in-situ parallel investigation under extreme heat conditions in tropical Singapore.

In the face of global rising temperatures and excessive urban heat, developing effective heat mitigation strategies has become increasingly urgent. Street shade, a typical cooling shelter for urban dwellers, has been primarily investigated for outdoor thermal comfort but not extensively under extreme heat conditions. This study explores the cooling efficacy of diverse street shade types in mitigating urban heat, thereby facilitating cities and their residents' adaptation to climatic shifts.

Many occupations, including military and industrial, cannot benefit from large-scale cooling strategies; therefore, personal cooling strategies may be more appropriate. We assessed the efficacy of a ventilated vest (Vest) based on participant' autonomic and cognitive responses during military-related activities in the heat. Male soldiers conducted 90-min trials in 35 °C ambient temperature and 40% relative humidity: i) March with/without Vest (N = 10), ii) Guard duty with/without Vest (N = 8).

Accurately predicting exposure of animals to climate change requires evaluating the effects of warming on the microclimates they occupy. Birds, like many other taxa, make extensive use of cool microsites in vegetation during hot weather. Taking advantage of recent advances in modelling tree canopy microclimates, we combined LiDAR-based individual tree canopy mapping and biophysical modelling to evaluate the current and future availability of cool microsites in a subtropical African savanna landscape.

Background: Global warming is raising increasing concerns about its impact on worker productivity, particularly in industries like construction where outdoor physically demanding jobs are prevalent. This study aimed to perform a meta-analysis to assess the existing evidence on the impact of heat exposure on productivity loss among construction workers.
Methods: We conducted a comprehensive literature search across six databases-Web of Science, PubMed, Embase, Scopus, ScienceDirect, and IEEE-covering the period from database inception to September 18, 2024.

Thermoregulatory behaviour determines an organism's body temperature and therefore its physiological condition, and may differ for organisms situated across climate gradients. Species' preferred or selected temperatures may be higher in warmer locations-referred to as coadaptation-or lower in warmer temperatures-countergradient variation. Here, we tested if rainforest amphibians exhibited coadaptation or countergradient thermal selection across an underappreciated spatial climate gradient (vertical height from forest floor to canopy) and separating diel activity (diurnal versus nocturnal behaviour).
