Effect on Human Health. Direct effects on human health of the emitted greenhouse gases are believed to be small. Other links between climate change and human health have not been well established, although modest effects could result. For example, temperature increases could stress human health such as heat stress, but in cold areas they could reduce stress. Some diseases... 

The demonstration plot of the experimental site should be constructed to evaluate the effectiveness of phytoremediation. The field activities consist of site mobilization, plot layout an construction, and soil sampling combined with other agricultural practices designed secifically for phytoremediation and adapted for the conditions present at the site. The activities has to be conducted in accodance with the personal protective equipment, level of protection, action levels and other health and safety practices, i.e. hazard analysis general safety reccomendations evaluation of the mechanical, electrical, fire hazards, gas and power lines, heat stress, noise, chemical hazards. 

M. Nonchemical physical exposures in the workplace are important because they can cause systemic effects that mimic chemical toxidromes. The most important example is heat stress, which is a major occupational health issue. Other relevant nonchemioal, work-related physical exposure types include ionizing radiation, nonionizing radiation (such as ultraviolet, infrared, and microwave exposure), and increased barometric pressure (eg, among caisson workers). Except for extremes of exposure, the adverse effects of these physical factors are generally associated with chronic conditions. 

Alagirusamy, 2010). Clothing is considered as a system that interacts with the body and must support thermoregulation of the body by maintaining its thermal balance (constant body core temperature of 37 °C) and providing a comfortable microclimate next to the skin (Li and Wong, 2006). Prevention of heat stress could lead to improved competitive performance for the athlete, whereas unnecessary heat and moisture next to the skin could have adverse effects on both performance and health. 

Work in an impermeable protective snit is a physical strain. The suit limits heat and moisture transport, which leads to elevation of skin and core temperature. This can resnlt in various health effects ranging from transient heat fatigue to serious illness, even death. The type of the clothing and its ventilation, the work activity, climate conditions, and the characteristics of the wearer of the clothing all influence the development of the heat stress.
